from Ralf Corsepius <corsepiu@faw.uni-ulm.de> that address the following:
* NoSource: 0, 1 in rpm-specs does not work anymore under SuSE-6.4
(rpm-3.0.4), putting each NoSource: onto a separate line however seems
to work. Unfortunately, I don't know the actual cause for this, esp. if
SuSE broke it or if rpm-specs specification has changed (i.e.
Redhat broke it up).
* Add *.spec to several .cvsignores (Prevents cvs from complaining about
<target>*.spec within the source-tree).

The patch contains:
* build variants support
* Reworked make-exe custom/*.cfg for all targets (Should be
self-explanatory, may still be incomplete)
* Several fixes to custom/*.cfgs related to setting debug flags
* Fixes to some bsp_specs for BSPs which apparently have never been
build with debugging before ;)
* pc386.cfg fix attempts (cf. my mail from earlier today)
* Updated ampolish (No need to run it, the patch contains the result
from having applied it)
Known bugs/deficiencies related to this work:
* "make [clean|distclean]" support is still incomplete (e.g. "make
clean" does not delete all Depends-o-*)
* Completely untested for linux/posix and hppa.
* Build failures of i960 BSPs (make VARIANT=DEBUG) - I guess, they are
not related to this patch.
* Successfully tested for all sh, sparc, i386, ppc, m68k BSPs (make
VARIANT=DEBUG)
* make VARIANT=PROFILE not supported by all BSPs (I don't care :)
* make VARIANT=DEBUG failures below tests/ for some BSPs (e.g. gensh1),
because of the tests's binaries being too large to fit into the target
memory layout.

that addresses the following:
* Duplicate variables in Makefiles (many Makefile.ams below c/src/test
are affected systematically)
* Erroniously using local.am instead of host.am in host-Makefile.am
(Only host Makefile.ams should be affected; Erroniously using local.am
in host-Makefiles doesn't desturb much)
* use '.' instead of '$pwd' in ./bootstrap (using $pwd does not work if
$pwd is a symlink on linux).
* Broken CVS Ids somewhere
* Removing redundant/obsolete make variables from *.cfg files.
Except of the last item from the list above, most parts of this patch
are fairly harmless, sometimes even cosmetical.
As mentioned before, this patch also contains a new ampolish script.
This script features:
* Pretty printing of Makefile.ams (eg. removal of trailing spaces,
removal of duplicate empty lines, pretty printing make variables, etc.).
* Some syntactical checks on the contents of Makefiles.am
* Proper handling of Automake conditionals
FYI:
* Applying tools/update/rtems-polish.sh -am completely reformats all
Makefile.am resulting into a very large (~500k) diff.
* Applying tools/update/rtems-polish.sh -am twice, finally does not
reformat the Makefile.ams anymore.
* Many parts of the patch above result from merging back issues which
have shown when applying this new ampolish (i.e. partially result from
extracting the essentials of reformating being proposed by applying it
on Makefile.ams).
Though this ampolish is a very nice tool, IMHO, I am hestitant if you
should apply (i.e. run tools/update/rtems-polish.sh -am) it to the
sources before the release, because
* the resulting diff is fairly large
* I am not 100% sure it doesn't break anything.
However, applying it after the release would result into compatibility
problems in applying patches ;)
I would suggest that you might consider trying it locally, then to
examine the diff and then to decide whether to apply it in general or
not.
Joel's Comments:
As Ralf points out, this patch is problematic in that applying it before
a release could break things but applying it afterwards will result in
patches being unusable for Makefiles. My inclination is to forge ahead
and apply it.

that fixes numerous miscellaneous issues most related to the debug and
profile build stanzas:
Fix for the "make debug" (1) issue and an analogous issue with "make
profile" (untested).
* Fixes to mcp750.cfg (make debug, directories) (2)
* Updates/minor fixes for shgen (3)
* Updates some custom/*.cfgs to use $(LINK.c) instead of $(CC)
* Leftovers from rtems-rc-4.5.0-[0|1].diff which somehow did not make it
into cvs.
* Cleanups to the perlscripts below tools/update/
* Some unsorted minor fixes.
Footnotes/Remarks:
(1) Tested for all m68k, sh, sparc, unix and selected i386, ppc BSPs.
Known problems: I can't build the debug variant for the m68k/mvme162 and
m68k/mvme162lx (segmentation fault - signal 11 :)
(2) Tested by building the BSP, but I doubt the debug-variant is
functional. The flags used for the debug variant should be checked by
knowledgeable persons and probably at runtime #:o)
(3) I have updated shgen to use getopt_long (it should fall back to
getopt if not available), enhanced the options, cleaned up some minor
tweaks and added help2man support (rough automatic man-page generation).
Technical notes:
* make debug and make profile now work similar in target Makefile.ams as
they did in old autoconf-Makefile.ins using leaf.cfg. Unlike the rules
in leaf.cfg these Makefile.am also recurse once on themselves in
directory Makefiles before or after recursing into subdirectories, not
only in leaf-directories.
To implement this behavior, I renamed the former automake/local.am into
automake/host.am and extended local.am to provide this recursion.
I.e. host.am implements the non-self-recursive variant, while local.am
now implements the self-recursive behavior.
=> all Makefile.ams exploiting build-variants are supposed to include
local.am
=> all Makefile.ams not exploiting build-variants should include host.am
=> Rules of thumb:
- Only include one of both, either local.am or host.am into a
Makefile.am.
-Target-Makefile.ams should include local.am
-Host-Makefile.ams should include host.am (Probably, you now understand
the naming)
- There are exceptions from these rules :)
* Now, make debug|profile|all are independent of each other. However,
each of them however triggers preinstall.
* "make install" still decends into the subdirectories but does not
trigger "all|profile|debug|preinstall" in target Makefile.am anymore.
Besides triggering "install"-rules in some selected Makefile.ams, it
only packs $(PROJECT_ROOT) into a tarballs and unpacks it to $(prefix).
=> "make install" alone is not enough to install RTEMS, now use
make RTEMS_BSP=<bsps> [all] [debug] [profile]
make RTEMS_BSP=<bsp> install
I consider this to be a step back wrt. exploiting automake mechanisms,
and expect this to be reverted if we abandon building target variants in
favour of the standard convention of optionally overriding flags from
the command line (i.e. instead of "make debug", GNU standards favor
"make CFLAGS=<options> --prefix=<location>")

that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)

which is described below:
This one is a (minor) patch in preparation of the upcoming patches. It
actually is an excerpt of the upcoming patches and therefore is
completely untested in this standalone form, but I don't expect it to
break something.
The essential changes in this patch are:
* An update to rtems-polish.sh (Now can also be run in subdirectories)
* A bug-fix for the libcpu/powerpc (A directory was missing from
SUBDIRS in a Makefile.am)
* An update to gensh2.cfg.
* Cleanups/Enhancements to configuration files

The patch below actuallly consists of two patches:
1) moving librpc to c/src/librpc similar to what has been done to librtems++
2) reworked configure scripts, many safety and dependency checks added to
aclocal/*.m4 macros + configuration fixes.
To apply:
mkdir c/src/librpc
mkdir c/src/librpc/src
cp c/src/lib/librpc/*.c c/src/librpc/src
cp c/src/lib/librpc/Makefile.in c/src/librpc/src
mkdir c/src/librpc/include
mkdir c/src/librpc/include/rpc
cp c/src/lib/include/rpc/* c/src/librpc/include/rpc
patch -p1 < ../rtems-rc-19990820-7.diff
rm -rf c/src/lib/librpc
rm -rf c/src/lib/include/rpc
./autogen
The additional checks in aclocal/*m4 macros add rather restrictive, sometimes
unnecessarily restrictive constraints on the sequence of how macros can be
used in a configure.in script. Adding them has let my problems with some more
complicated configuration options vanish. Apparently some macros had not been
in the required order .

This patch addresses a few configuration issues and removes some
duplicate configuration files.
Background:
* some files used in AC_INIT were not unique enough and can lead to
problems if a user plays with configure scripts.
* the Makefile templates are independent of the target/cpu and bsp, so
the bsp dependent versions (c/src/make/Templates) are removed.
To apply:
patch -p1 < rtems-rc-19990820-3.diff
rm -f c/src/make/Templates
./autogen
ATTENTION: This patch removes several files and one directory :)

1. Addition of maintainer-mode dependencies on config.status and
aclocal.m4 for autoconf toplevel Makefile.ins. These rules are taken
over from automake generated Makefile.ins, i.e. they are contained in
any automake generated toplevel Makefile.in. Having this patch in is at
least a great releaf for me when working on RTEMS configuration :)
2. Automated support for #1 in acpolish
3. Some minor "beautifications" on Makefile.ins resulting from running
acpolish.
FYI: This patch has been generated by running
tools/update/rtems-polish.sh -ac on the source tree and manually editing
the resulting patch afterwards to work around a problem with acpolish,
which still corrupts one Makefile.in - WARNING: Be careful with running
acpolish!

settings (network, multiprocessing, etc) gnerated by autoconf.

The patch below fixes a nasty bug in acpolish, which has broken many
Makefile.ins below c/src/tests/
APPLYING THE PATCH:
patch -p1 < rtems-rc-19990709-5.diff

The main topic is replacing the hard-coded values for HAS_MP and
HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks
(This is the patch I had mentioned before earlier this week).
CHANGES
* HAS_MP removed from custom/*.cfg, replaced with configuration time
autoconf check
* HAS_RDBG removed from custom/*.cfg, replaced with configuration-time
autoconf check
* NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp
values (i.e. HAS_MP, HAS_RDBG), gets installed as
$(prefix)/<bsp>/make/bsp.cfg
* NEW: default.cfg includes bsp.cfg - this change is backward
compatible.
* IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory
Makefile.ins
* HACK: a bug in acpolish mis-handles addtions to makefile variables
which are enclosed in gmake conditionals:
c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in
* Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of
unneeded subdirectories in various configure.in files.
* Several minor changes in Makefile.ins and configure.ins, wrt. to the
order of including *.cfg and defining Makefile variables

This patch is an addition to "The big-patch"
CHANGES:
* FIX: c/Makefile.am: bogus comment which changed the behavior of
c/Makefile.am removed
* FIX: make/custom/ts_i386ex.cfg did not set HAS_NETWORKING correctly
(Me thinks it might have been me who added this bogus setting :-).
* NEW: removing make targets get, protos, debug_install, profile_install
* NEW: replacing clobber with distclean
* NEW: Reimplement distclean and clean as reverse depth first make
targets (adaptation to automake's behavior)
* NEW: removing RCS_CLEAN from make distclean (tools/build/rcs_clean is
still in - remove it?)
* NEW: "$(RM) Makefile" added to make distclean (adaptation to
automake's behavior)
* NEW: "$(RM) config.cache config.log" to CLOBBER_ADDITIONS in
[lib|exec|tests]/Makefile.in (adaptation to automake's behavior)
* NEW: "$(CLEAN_PROTOS)" removed (Not used anywhere)
* NEW: binpatch.c moved from i386 bsp tools to tools/build (AFAIS,
binpatch is not specific to the pc386 BSP at all)
* NEW: AC_EXEEXT added to all configure scripts which contain AC_PROG_CC
(Cygwin support)
* NEW/Experimental: An experimental implementation of temporary
installation tree support in libbsp/i386/pc386/tools/Makefile.am, based
on dependency tracking with make, instead of applying INSTALL_CHANGE.
REMARK:
* This patch is small in size, but changes the behavior of "make
clean|distclean|clobber" basically.
* This patch does not alter building/compiling RTEMS, ie. there should
be no need to rerun all "make all" building tests.
KNOWN BUGS:
* make RTEMS_BSP="..." distclean in c/ runs "make distclean" in BSPs
subdirectories passed through RTEMS_BSP and in "c/." only, but does not
descend into other BSP subdirectories previously configured with
different settings of make RTEMS_BSP="...".
=> Workaround: always use the same setting of RTEMS_BSP when working
inside the build-tree.
* "make [distclean|clean]" do not clean subdirectories, which have been
configured at configuration time, but which are not used due to
make-time configuration (e.g. macros/networking/rdgb subdirectories).
This will problem will vanish by itself when migrating from make-time to
configuration-time configuration

A bug in acpolish made it into rtems-rc-19990709-0.diff, which
unfortunately affects all Makefile.ins:
* The maintainer mode conditional was erroniously applied to the
dependencies of "Makefile".
In case you already checked in rtems-rc-19990709-0.diff to CVS you have
to check in all Makefile.ins again after applying the patch below :).
Please apply the patch below as follows:
patch -p1 < rtems-rc-19990709-1.diff
tools/update/rtems-polish.sh -ac
Note: There is no need to rerun your tests if you have used
--enable-maintainer-mode to configure RTEMS, because this patch converts
all Makefile.ins to the same settings as used for
--enable-maintainer-mode.

to move RTEMS more to automake/autoconf and GNU compliance.
Finally, here they are: the "big-patch" patches - merged into one big
patch (~1.5MB).
Sorry for the delay, but testing took much more time than I had expected
- esp. reworking the acpolish script triggered many more tiny issues
than I had expected (cf. below).
At least, now you've got something to spend your weekend with :-.
WARNINGS:
* I've gone a little (??) further than I had announced before.
* Several directories have been moved.
* Several files have been added and removed
* I have tested it with many BSPs/CPUs and a variety of permutiations of
configuration flags, but not with all.
* Most parts of the patch are automatically generated, however there are
many tiny manual modifications.
APPLYING THE PATCH:
./autogen -c
mkdir tools
mv c/src/exec/score/tools tools/cpu
mv c/build-tools tools/build
mv c/update-tools tools/update
patch -p1 -E < rtems-rc-19990709-0.diff
./autogen
If the patch doesn't apply to rtems-cvs, I would suggest that you should
try to apply it brute-force and then to run tools/update/rtems-polish.sh
-ac -am afterwards. A recursive diff between rtems-19990709 + patch and
rtems-cvs + patch then should report only a few dozen significant
changes to configuration files which need to be merged manually (IIRC, I
did not change any source files).
*** Attention: There are files to be removed, moved, copied and added
in/to CVS!
NEWS/CHANGES:
1. Configuration takes place in 3 stages: 1. per host (toplevel
configure script), 2. per target (c/configure), 3. per bsp
c/src/configure automatically triggered from ./configure and
c/Makefile.am.
2. Building of subdirectory c/ takes place in c/$(target_alias) for
cross-targets in c/ for native targets
3. Building of subdirectory c/src takes place in c/${target_alias}/<bsp>
for cross-targets, c/<bsp> for native targets
4. c/build-tools moved to tools/build
5. c/src/exec/score/cpu/tools moved to tools/cpu (=cpu-tools split out)
6. c/update-tools moved to tools/update
7. New subdirectory c/src/make, handles files from make/ on a per BSP
basis
8. Maintainer mode support: Ie. if configuring with
--enable-maintainer-mode disabled (the default), then tracking of many
dependencies will be disabled in Makefiles. Esp. many dependencies for
auto* generated files will be switched off in Makefiles. Ie. if not
using "--enable-maintainer-mode" many auto* generated files will not be
updated automatically, i.e. normal users should not be required to have
auto* tools anymore (untested).
9. Independent configuration scripts for / (toplevel), tools/build,
tools/cpu, tools/update, c/, c/src/, c/src/exec, c/src/lib, c/src/tests,
c/src/make
10. Automake support for all directories above and besides c/src
11. "preinstall" now is implemented as depth-first recursive make target
12. host compiled tools (exception bsp-tools) are accessed in location
in the build tree instead of inside the build-tree when building RTEMS.
13. RTEMS_ROOT and PROJECT_ROOT now point to directories inside the
build-tree - many tiny changes as consequence from this.
14. --with-cross-host support removed (offically announced obsolete by
cygnus)
15. Changing the order of building libraries below c/src/lib/
16. Former toplevel configure script broken into aclocal/*.m4 macros
17. Newlib now detected by configure macros, RTEMS_HAS_NEWLIB removed
from *cfg.
18. sptables.h now generated by autoconf
19. Rules for "mkinstalldirs temporary installation tree" moved from
c/Makefile to subdirectories.
20. Cpu-tools do not get installed.
21. FIX: Use ACLOCAL_AMFLAGS instead of ACLOCAL = -I ... in Makefile.ams
which are in directories with own configure scripts.
22. Hardcoding BSP names into libbsp/.../tools to avoid RTEMS_BSP get
overridden from the environment.
22. FIX: Handling of MP_PIECES in various Makefiles
23. FIX: Removing "::" rules from some Makefile.ins
24. FIX: File permission chaos: (-m 444 and -m 555 vs. -m 644 and -m
755) - Now all include files use -m 644.
25. Removed many gnumake-conditionals in Makefile.ins - Partially
replaced with automake-conditional, partially replaced with
conditionalized Makefile variables (... _yes_V)
26. Massively reworked acpolish: acpolish now parses Makefile.ins and
interprets parts of the Makefile.ins.
27. FIX: Some $(wildcard $(srcdir)/*.h) macros removed / replaced with
explicit lists of files in Makefile.ins.
28. FIX: Replacing MKLIB with RANLIB in Makefile.ins
29. HACK: Add preinstallation for pc386 specific
$(PROJECT_RELEASE)/BootImgs directory
... many more details, I can't recall
KNOWN BUGS:
1. make [debug|profile]_install do not do what they are promissing.
"make [debug|profile] install" does what "make [debug|profile]_install"
has been doing. Proposal: remove [debug|profile]_install
2. Dependencies between temporary installation tree and source tree are
not yet handled correctly.
3. Dependencies between temporary installation tree and source tree are
handled ineffencently (Using INSTALL_CHANGE instead of make
dependencies)
4. RTEMS_ROOT, PROJECT_ROOT, top_builddir, RTEMS_TOPdir now are
redundant.
5. The new configure scripts still are in their infancy. They contain
redundant checks and might still contain bugs, too.
6. RTEMS autoconf Makefile.ins use a mixture of configuration
information gathered in c/$(target_alias)/<bsp>/make and of information
collected from their configure scripts.
7. make dist is not fully functional
8. Subdirectory host-/build-/target- configure options (--target,
--host, --build) do not conform to Cygnus/GNU conventions.
9. Some RTEMS autoconf Makefile.in's makefile targets are not supported
in automake Makefile.ams/ins (e.g. get, clobber).
10. Some automake standard targets are not propagated from toplevel and
c/Makefile.am to autoconf subdirectories (eg. make dist).
11. rpcgen generated files are not part of the source-tree (Automake
conventions favor supplying generated files inside the source-tree,
however there is no support for rpcgen generated files in automake, cf.
yacc/lex support in automake).
12. RTEMS_HAS_RDBG handling is flaky. make/*.cfg use RTEMS_HAS_RDBG per
CPU, while librdb's sources can only be built per BSP. Raises the more
general question whether librdbg located correctly in the source-tree.
13. All make/*cfg files are configured per cpu, currently there is no
location to store per-bsp configuration information --> bsp.cfg, per
aconfig.h?
14. "make install" without having run "make all" beforehand does not
work.
15. handling of --enable-multiprocessing seems to be broken in
make/custom/*
16. Makefile.ins still exploit many gmake features.
17. File permisson chaos on libraries (no explict -m for
libraries/rels/etc).
18. mcp750 Makefiles are broken (Note: I *do* mean buggy - I am not
talking about "not-conforming to conventions", here :-).
19. Dependencies between configure scripts are not handled, eg. aborting
"make RTEMS_BSP=<bsp>" can leave the build-tree in an unusable state.
20. "make clean" does not delete <build-tree>/<bsp>. This is intentional
for now, because rerunning "make" after "make clean" requires an
explicit "make preinstall" afterwards now. This should be done
automatically, but doesn't work in this case for now. To work around
this problem <build-tree>/<bsp> is kept during "make clean" for now
(HACK).
TODO:
1. split out host-compiled bsp-tools
2. Use Cygnus/GNU standards for cross-compiling target-subdir
(CC=CC_FOR_TARGET .. configure --host=${target_alias}
--build=`config.guess'}), to be added to toplevel configure script after
splitting out bsp-tools.
3. Exploit per cpu support directory (c/src/<cpu>)- Splitting out
per-cpu libraries - Are there any?
4. Further automake support
5. Converting subdirectories into standalone / self-contained
subdirectories (Esp. moving their headers to the same common root as
their sources, eg. mv lib/include/rtems++
lib/librtems++/include/rtems++) - This is the main obstacle which
prevents moving further towards automake.
6. Propagating values from *.cfg into Makefiles instead of propagating
them at make time via Makefile-fragments (i.e. try to avoid using
*.cfg).
7. Testing on cygwin host (I *do* expect cygwin specific problems).
8. The ARCH in o-$(ARCH)-$(VARIANT) build-subdirectories is not needed
anymore.
GENERAL ISSUES:
1. Temporary installation tree -- Ian and I seem to disagree basically.
Though I think that I understand his argumentation, I do not share it.
IMO, his way of using the buildtree is mis-using the build-tree, relying
on an inofficial feature of RTEMS's current implementation, which
doesn't even work correctly in the current build-tree, though it
attempts hard to do so. From my very POV, it unnecessarily complicates
the structures of the source- and build-trees. It is not supported by
automake (No automatic generation for the necessary rules) and
complicates the transition to automake significantly (Generating the
rules with an enhanced version of acpolish could be possible).
As Ian correctly pointed out, here a management decision is needed -
though I don't see the need to draw this decision in short terms.
2. preinstallation generally is a sure means to spoil the structure of
the source tree, IMHO (No ranting intended, I am completly serious about
this one). eg. through tree dependencies. The worst problem related to
this I have found in the meantime is bsp_specs. bsp_specs is part of
libbsp, ie. there is *no* way to build *any* part of the source tree
*without* having a BSP *preinstalled*.
Note: This issue is related to issue 1., but is not identical - The
difference is the change of the order make rules have to be triggered.
While preinstallation triggers rules spread all over the source tree
before a "make all" can be run, a temporary installation tree could also
be installed by post "make all" hooks (all-local:, to be run after make
all in a directory is completed) if the directories' dependencies would
be a tree,
3. Stuctural dependencies between subdirectories.
4. Depth of the source tree (Prevents multilibbing and introduces many
unnecessary configure scripts).
5. per cpu vs. per bsp configuration (There are no real per-cpu parts
yets :-).
6. automake does not support $makefiles in AC_OUTPUT. Unlike before, we
now should try to avoid RTEMS_CHECK_MAKEFILE and to hard-code as much
paths to Makefiles as possible.
7. General redesign of the source tree
8. Main installation point - Changing it to ${prefix}/${target_alias}. ?
Besides item 8. (which is a must, IMHO), as far as I see most of them
can not be solved soon and will remain issues in the mid- to long-term
:-.
REMARKS:
* You (as the maintainer) should always use --enable-maintainer-mode
when building RTEMS to ensure that maintainer mode generated files (esp.
those in c/src/make) will be updated when make/* files have changed.
* Use @RTEMS_BSP@ in Makefile.ins and Makefile.ams below c/src/,
$(RTEMS_BSP) or ${RTEMS_BSP} will be overridden from environment
variables when using make RTEMS_BSP="....".
* c/src/make is a temporary cludge until configuration issues are
solved. At the moment it is configured per bsp, but contains
per-target/cpu info only. Its main purpose now is to circumvent
modifying make/*.cfg files, because I consider make/* to be frozen for
backward compatibilty.
* This patch should only affect configuration files. At least I do not
remember having touched any source files.
* To build the bare bsp you now need to mention it in --enable-rtemsbsp.
Example: building gensh1 and sh1/bare simultaneously:
../rtems-rc-19990709-1/configure --target=sh-rtems \
--enable-rtemsbsp="bare gensh1" \
--prefix=/tmp/rtems \
--enable-bare-cpu-cflags='-DMHZ=20 -m1
-DCPU_CONSOLE_DEVNAME=\"/dev/null\"' \
--enable-bare-cpu-model=sh7032 \
--enable-maintainer-mode \
--enable-cxx
make
make install
* The next steps in development would be to split out bsp-tools and then
to change to Cygnus/GNU canonicalization conventions for building the c/
subdirectory afterwards (i.e. many standard AC_*.m4 macros could be used
instead of customized versions)
FINAL REMARK:
The issues mentioned in the lists above sound much worser than the
situation actually is. Most of them are not specific to this patch, but
are also valid for the snapshot. I just wrote down what I came across
when working on the patch over the last few weeks.
I wouldn't be too surprised if you don't like the patch at the current
point in development. I am willing to discuss details and problems, I
also have no problem if you would post-pone applying this patch to times
after 4.1, but rejecting it as a whole for all times would be a false
management decision, IMHO.
Therefore I would suggest that you, if your time constaints allow it,
should at least play a little while with this patch to understand what
is going on and before drawing a decision on how to handle this
proposal. I know this patch is neither perfect nor complete, but I
consider it to be a major breakthrough. Don't be anxious because of the
size of the patch, the core of the patch is rather small, the size is
mainly the side effect of some systematic cleanups inside the Makefiles
(result of acpolish).
Feel free to ask if you encounter problems, if you don't understand
something or if you meet bugs - I am far from being perfect and am
prepared to answer them.
Ralf.

patch -p1 -E < rtems-rc-19990709-0.diff

using "--enable-maintainer-mode" many auto* generated files will not be
updated automatically, i.e. normal users should not be required to have
auto* tools anymore (untested).
9. Independent configuration scripts for / (toplevel), tools/build,
tools/cpu, tools/update, c/, c/src/, c/src/exec, c/src/lib, c/src/tests,
c/src/make
10. Automake support for all directories above and besides c/src
11. "preinstall" now is implemented as depth-first recursive make target
12. host compiled tools (exception bsp-tools) are accessed in location
in the build tree instead of inside the build-tree when building RTEMS.
13. RTEMS_ROOT and PROJECT_ROOT now point to directories inside the
build-tree - many tiny changes as consequence from this.
14. --with-cross-host support removed (offically announced obsolete by
cygnus)
15. Changing the order of building libraries below c/src/lib/
16. Former toplevel configure script broken into aclocal/*.m4 macros
17. Newlib now detected by configure macros, RTEMS_HAS_NEWLIB removed
from *cfg.
18. sptables.h now generated by autoconf
19. Rules for "mkinstalldirs temporary installation tree" moved from
c/Makefile to subdirectories.
20. Cpu-tools do not get installed.
21. FIX: Use ACLOCAL_AMFLAGS instead of ACLOCAL = -I ... in Makefile.ams
which are in directories with own configure scripts.
22. Hardcoding BSP names into libbsp/.../tools to avoid RTEMS_BSP get
overridden from the environment.
22. FIX: Handling of MP_PIECES in various Makefiles
23. FIX: Removing "::" rules from some Makefile.ins
24. FIX: File permission chaos: (-m 444 and -m 555 vs. -m 644 and -m
755) - Now all include files use -m 644.
25. Removed many gnumake-conditionals in Makefile.ins - Partially
replaced with automake-conditional, partially replaced with
conditionalized Makefile variables (... _yes_V)
26. Massively reworked acpolish: acpolish now parses Makefile.ins and
interprets parts of the Makefile.ins.
27. FIX: Some $(wildcard $(srcdir)/*.h) macros removed / replaced with
explicit lists of files in Makefile.ins.
28. FIX: Replacing MKLIB with RANLIB in Makefile.ins
29. HACK: Add preinstallation for pc386 specific
$(PROJECT_RELEASE)/BootImgs directory
... many more details, I can't recall
KNOWN BUGS:
1. make [debug|profile]_install do not do what they are promissing.
"make [debug|profile] install" does what "make [debug|profile]_install"
has been doing. Proposal: remove [debug|profile]_install
2. Dependencies between temporary installation tree and source tree are
not yet handled correctly.
3. Dependencies between temporary installation tree and source tree are
handled ineffencently (Using INSTALL_CHANGE instead of make
dependencies)
4. RTEMS_ROOT, PROJECT_ROOT, top_builddir, RTEMS_TOPdir now are
redundant.
5. The new configure scripts still are in their infancy. They contain
redundant checks and might still contain bugs, too.
6. RTEMS autoconf Makefile.ins use a mixture of configuration
information gathered in c/$(target_alias)/<bsp>/make and of information
collected from their configure scripts.
7. make dist is not fully functional
8. Subdirectory host-/build-/target- configure options (--target,
--host, --build) do not conform to Cygnus/GNU conventions.
9. Some RTEMS autoconf Makefile.in's makefile targets are not supported
in automake Makefile.ams/ins (e.g. get, clobber).
10. Some automake standard targets are not propagated from toplevel and
c/Makefile.am to autoconf subdirectories (eg. make dist).
11. rpcgen generated files are not part of the source-tree (Automake
conventions favor supplying generated files inside the source-tree,
however there is no support for rpcgen generated files in automake, cf.
yacc/lex support in automake).
12. RTEMS_HAS_RDBG handling is flaky. make/*.cfg use RTEMS_HAS_RDBG per
CPU, while librdb's sources can only be built per BSP. Raises the more
general question whether librdbg located correctly in the source-tree.
13. All make/*cfg files are configured per cpu, currently there is no
location to store per-bsp configuration information --> bsp.cfg, per
aconfig.h?
14. "make install" without having run "make all" beforehand does not
work.
15. handling of --enable-multiprocessing seems to be broken in
make/custom/*
16. Makefile.ins still exploit many gmake features.
17. File permisson chaos on libraries (no explict -m for
libraries/rels/etc).
18. mcp750 Makefiles are broken (Note: I *do* mean buggy - I am not
talking about "not-conforming to conventions", here :-).
19. Dependencies between configure scripts are not handled, eg. aborting
"make RTEMS_BSP=<bsp>" can leave the build-tree in an unusable state.
20. "make clean" does not delete <build-tree>/<bsp>. This is intentional
for now, because rerunning "make" after "make clean" requires an
explicit "make preinstall" afterwards now. This should be done
automatically, but doesn't work in this case for now. To work around
this problem <build-tree>/<bsp> is kept during "make clean" for now
(HACK).
TODO:
1. split out host-compiled bsp-tools
2. Use Cygnus/GNU standards for cross-compiling target-subdir
(CC=CC_FOR_TARGET .. configure --host=${target_alias}
--build=`config.guess'}), to be added to toplevel configure script after
splitting out bsp-tools.
3. Exploit per cpu support directory (c/src/<cpu>)- Splitting out
per-cpu libraries - Are there any?
4. Further automake support
5. Converting subdirectories into standalone / self-contained
subdirectories (Esp. moving their headers to the same common root as
their sources, eg. mv lib/include/rtems++
lib/librtems++/include/rtems++) - This is the main obstacle which
prevents moving further towards automake.
6. Propagating values from *.cfg into Makefiles instead of propagating
them at make time via Makefile-fragments (i.e. try to avoid using
*.cfg).
7. Testing on cygwin host (I *do* expect cygwin specific problems).
8. The ARCH in o-$(ARCH)-$(VARIANT) build-subdirectories is not needed
anymore.
GENERAL ISSUES:
1. Temporary installation tree -- Ian and I seem to disagree basically.
Though I think that I understand his argumentation, I do not share it.
IMO, his way of using the buildtree is mis-using the build-tree, relying
on an inofficial feature of RTEMS's current implementation, which
doesn't even work correctly in the current build-tree, though it
attempts hard to do so. From my very POV, it unnecessarily complicates
the structures of the source- and build-trees. It is not supported by
automake (No automatic generation for the necessary rules) and
complicates the transition to automake significantly (Generating the
rules with an enhanced version of acpolish could be possible).
As Ian correctly pointed out, here a management decision is needed -
though I don't see the need to draw this decision in short terms.
2. preinstallation generally is a sure means to spoil the structure of
the source tree, IMHO (No ranting intended, I am completly serious about
this one). eg. through tree dependencies. The worst problem related to
this I have found in the meantime is bsp_specs. bsp_specs is part of
libbsp, ie. there is *no* way to build *any* part of the source tree
*without* having a BSP *preinstalled*.
Note: This issue is related to issue 1., but is not identical - The
difference is the change of the order make rules have to be triggered.
While preinstallation triggers rules spread all over the source tree
before a "make all" can be run, a temporary installation tree could also
be installed by post "make all" hooks (all-local:, to be run after make
all in a directory is completed) if the directories' dependencies would
be a tree,
3. Stuctural dependencies between subdirectories.
4. Depth of the source tree (Prevents multilibbing and introduces many
unnecessary configure scripts).
5. per cpu vs. per bsp configuration (There are no real per-cpu parts
yets :-).
6. automake does not support $makefiles in AC_OUTPUT. Unlike before, we
now should try to avoid RTEMS_CHECK_MAKEFILE and to hard-code as much
paths to Makefiles as possible.
7. General redesign of the source tree
8. Main installation point - Changing it to ${prefix}/${target_alias}. ?
Besides item 8. (which is a must, IMHO), as far as I see most of them
can not be solved soon and will remain issues in the mid- to long-term
:-.
REMARKS:
* You (as the maintainer) should always use --enable-maintainer-mode
when building RTEMS to ensure that maintainer mode generated files (esp.
those in c/src/make) will be updated when make/* files have changed.
* Use @RTEMS_BSP@ in Makefile.ins and Makefile.ams below c/src/,
$(RTEMS_BSP) or ${RTEMS_BSP} will be overridden from environment
variables when using make RTEMS_BSP="....".
* c/src/make is a temporary cludge until configuration issues are
solved. At the moment it is configured per bsp, but contains
per-target/cpu info only. Its main purpose now is to circumvent
modifying make/*.cfg files, because I consider make/* to be frozen for
backward compatibilty.
* This patch should only affect configuration files. At least I do not
remember having touched any source files.
* To build the bare bsp you now need to mention it in --enable-rtemsbsp.
Example: building gensh1 and sh1/bare simultaneously:
../rtems-rc-19990709-1/configure --target=sh-rtems \
--enable-rtemsbsp="bare gensh1" \
--prefix=/tmp/rtems \
--enable-bare-cpu-cflags='-DMHZ=20 -m1
-DCPU_CONSOLE_DEVNAME=\"/dev/null\"' \
--enable-bare-cpu-model=sh7032 \
--enable-maintainer-mode \
--enable-cxx
make
make install
* The next steps in development would be to split out bsp-tools and then
to change to Cygnus/GNU canonicalization conventions for building the c/
subdirectory afterwards (i.e. many standard AC_*.m4 macros could be used
instead of customized versions)
FINAL REMARK:
The issues mentioned in the lists above sound much worser than the
situation actually is. Most of them are not specific to this patch, but
are also valid for the snapshot. I just wrote down what I came across
when working on the patch over the last few weeks.
I wouldn't be too surprised if you don't like the patch at the current
point in development. I am willing to discuss details and problems, I
also have no problem if you would post-pone applying this patch to times
after 4.1, but rejecting it as a whole for all times would be a false
management decision, IMHO.
Therefore I would suggest that you, if your time constaints allow it,
should at least play a little while with this patch to understand what
is going on and before drawing a decision on how to handle this
proposal. I know this patch is neither perfect nor complete, but I
consider it to be a major breakthrough. Don't be anxious because of the
size of the patch, the core of the patch is rather small, the size is
mainly the side effect of some systematic cleanups inside the Makefiles
(result of acpolish).
Feel free to ask if you encounter problems, if you don't understand
something or if you meet bugs - I am far from being perfect and am
prepared to answer them.
Ralf.

-- configure now fails to detect the toolchain for linux-posix.
As work-around, I have reverted to the old behavior of RTEMS_TARGET_CPU_NAME,
thus no_cpu/no_bsp will fail badly in configure again.

Yep, I think I know what's going on.
AC_SUBST(RTEMS_CPU) is missing in configure.ins, thus @RTEMS_CPU@ in
target.cfg.in doesn't get substituted correctly, causing the bug above. Due
to the redundancy of RTEMS_CPU, other most BSPs don't seem to be affected.
Other similar problems probably exist for the unix/posix bsp and the hppa.1
cpu, because their */tools/*Makefile.ams require RTEMS_CPU, too.

This patch should fix the nastiest configuration bugs for no_cpu/no_bsp.
With this patch applied, configure --target=no_cpu-rtems now correctly
acknowledges its configuration, but later fails building when trying to
build libcsupport (I leave this problem for you :-).
Fixes/Changes:
* aclocal/canonicalize-target-name.m4: use RTEMS_CPU instead of
target_cpu, switch to a native compiler setup if target = no_cpu*rtems,
ie. implicitly use host=target (native) and RTEMS_CPU=no_cpu for
--target=no_cpu*rtems.
* add no_bsp/bsp_specs (Support -qrtems, -qrtems_debug; please check
before adding :-)
* Use RTEMS_CANONICALIZE_TARGET_CPU instead of AC_CANONICAL_SYSTEM in
toplevel/configure.in
* All references to $target_cpu in aclocal/*.m4, Makefile.ins and *.cfg
files changed to RTEMS_CPU
* bug fixes to exec/score/cpu/no_cpu/wrap (This part of the patch may
result into patch rejections, because your recently posted patch may
also have addressed this problem).
After applying this patch, please do:
cvs add c/src/lib/libbsp/no_cpu/no_bsp/bsp_specs

This patch fixes a nasty problem with build-tools/Makefile.am:
When using install-sh instead of /usr/bin/install, only the first file
gets installed during the preinstall stage.

the build-tools layout to simplify it.
This script reorganizes and simpilfies the build-tools subdirectories.
It moves all source-files and scripts to c/build-tools/. This will
enable use to use this directory directly to refer to the build-tools
instead of copying them around in a "preinstall" step in future.
However, RTEMS's autoconf Makefile.ins and *.cfg files are not yet
prepared to apply this approach and therefore require additional work.

This one is an enhancement to acpolish.
It replaces some Makefile variables by others variable in Makefile.ins
(tries to use unique name for some variables). It therefore eases
parsing Makefile.ins for further automatic Makefile.in conversions in
future.
To apply:
cd <rtems-source-tree>
sh <path-to>/rtems-rc-19990407-8.sh
./autogen

FYI: I am not talking about using "make -C <dir>", which probably
is much faster on M$ hosts than RTEMS's implementation, but about
removing --enable-gmake-print support and to apply a variant of
automake's subdirectory.
Automake's subdirectory rule seems to be a little bit faster, but I
wouldn't bet on this.
Attached to this mail is my proposal.
After applying the patch, please run
cvs rm aclocal/enable-gmake-print.m4

This patch addresses a few minor issues and contains a few (minor)
preparations for automake.
* configure.in: Fix for handing c/src/tests subdirectory handling (FIX)
* aclocal/rtems-top.m4:
+ Add TARGET_SUBDIR and --with-target-subdir (preparation of future
enhancements for cross-compiling)
+ Activate RTEMS_ROOT handling (automake preparation)
* automake/*.am: replace comments "#" with "##" so that comments won't
get included into Makefile.in's anymore
* c/update-tools/* automake support (NEW)
* ./autogen update/enhancement (cf. ./autogen for details)
After applying this patch please run:
./autogen
cvs add c/update-tools/configure.in
cvs add c/update-tools/Makefile.am
cvs add c/update-tools/aclocal.m4
