that is yet another multilib-related structual cleanup patch:
Changes:
* Make RTEMS_TEST_NO_PAUSE a tests/ subpackage specific option.
- Remove RTEMS_TEST_NO_PAUSE from custom/*.cfg, targopts.h and
cpuopts.h.
- Add autoconf macros RTEMS_*_RTEMS_TEST_NO_PAUSE
(aclocal/rtems-test-no-pause.m4).
- Add RTEMS_*_RTEMS_TEST_NO_PAUSE support to sptests/configure.ins
and tmtests/configure.in. These are the only subdirectories which
currently apply RTEMS_TEST_NO_PAUSE.
- Add autoconf-DEFS support to all test subpackages' configure.ins
below tests/. I.e. AC_DEFINES now get explicitly propagated as
preprocessor defines into Makefiles, cf. AM_CPPFLAGS in
tests/*/*.am, instead of using a global config-files.
- Remove NDEBUG from custom/*.cfg.
* AC_DEFINE POSIX_API, ITRON_API and MULTIPROCESSING in
exec/configure.in, only.
- All other sources now should relay on the values from cpuopts.h
and should not define them themselves.
- Several related changes to many configure.ins
* Bug-fixes to RTEMS_*_RTEMS_DEBUG macros (Actually workarounds to
quoting bugs in autoconf).
Notes:
* This patch is rather immature and only tested for a small subset
of BSPs (requires the tests to be enabled and therefore takes an
tremendous amount of disc space and time.)
* The patches to *cfg were generated by a script. Expect file
formating changes :)

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)

that contains:
* cleanups to configuration files
* A reworked gccnewlib.spec.in: I have reformated it for enhanced
readability and added more rtems-base packages. It now should be free of
any installation conflicts (If there still remain some, they should be
regarded as bugs).
* A fix to the bin2boot RTEMS_BSP issue (make RTEMS_BSP="pc386 pc486"
now works).
* removes libbsp/bare/wrapup
* Further cleanups

that converts the a29k to automake.
This patch contains
* An initial merger of the libcpu/a29k stuff you sent yesterday. AFAIS,
most code inside them seems to be empty stubs. One file even contains a
function called mips_*** which might indicate that this part might
contain mips code or the code the initial porter used as template for
porting. Unfortunately, I don't know anything about the a29k so I can't
comment on the details.
* A dummy bsp_specs to libbsp/29k/portsw
* An update to the automake files related to the a29k.
Note:
* This patch is completely untested, because I don't have a toolchain
for it.
* The files in libcpu/a29k include bsp.h => The libbsp vs. libcpu-issue
hits again.

.. a major configuration cleanup
... major enhancement of automake support.
... and it contains a *major* breakthough:
Automake support for libchip and libmisc *LEAF* directories.
To implement this I have used several nasty tricks
* The basical trick is to wrap an old Makefile.in's contents into a
Makefile.am and still continue to use (i.e include) the old
*.cfg files.
* Replaced each INSTALL_IF_CHANGE and INSTALL_VARIANT with make
dependencies
* Add a gnu-make ifdef AUTOMAKE to main.cfg to avoid conflicts between
automake and RTEMS make rules
* Replaced each install:: and preinstall:: rule with make dependencies
* Replaced SUB_DIRS with SUBDIRS in all Makefile.ins (Automake
convention)
* Removed each manually added autoconf substitution which automake
performs automatically.
This is not yet full automake support, because using the temporary
installation directory, preinstallation in general and building variants
are in contradiction to automake's basic working principles ...
... the new Makefile.ams work still somewhat clumsy
... nevertheless they work (quite well).
WARNING:
At first glance this patch is small, but
* it affects the whole configuration system.
* it opens the road to introducing automake to all Makefile.ins
currently not being under automake control.
JOEL> Does this remove or add any files?
Both, all Makefile.ins below libchip and libmisc get replaced with
Makefile.ams.

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 \

* 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.

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

This patch is the most scary of all proposals I've been mailing to you
this week until now.
It consists of 3 parts:
1. a patch
2. a perl script (acpolish)
3. a shell script wrapper to invoke the perl-script.
The perl-script reads in each Makefile.in and modifies them
("polishes/beautifies" them :-).
These modifications are not easy to describe:
Basically, it hard-codes some automake Makefile-variables and rules into
RTEMS autoconf-Makefile.ins (Note: autoconf vs. automake!!) and converts
some settings/variables to configure scripts' requirements (Yes,
plural).
E.g. it adds the automake standard variables $top_builddir and $subdir,
adds dependency rules for automatic re-generation of Makefiles from
Makefile.in, adds support variables for relative paths to multiple
configure scripts etc.
The patch is a one-line patch to enable the support of the new features
added by acpolish.
The shell script is a wrapper which pokes around inside of the source
tree for Makefile.ins and invokes acpolish on all autoconf-Makefile.ins.
acpolish is designed to be able to run several times on the same
Makefile.in and may once become a more general tool to convert RTEMS
Makefile.in to automake. Therefore, I'd like to keep it inside of source
tree. (e.g. as contrib/acpolish or c/update-tools/acpolish). However, it
doesn't make sense to export it outside of RTEMS.
To apply this:
cd <source-tree>
patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff
tar xzvf <path-to>/rtems-rc-polish.tar.gz
./rtems-polish.sh
./autogen
Note: The path contrib/acpolish is hard-coded into rtems-polish.sh, if
you decide to put it in an alternative place, please modify
rtems-polish.sh to reflect this change.
Later:
cvs rm make/rtems.cfg (It isn't used anymore)
cvs add contrib
cvs add contrib/acpolish
cvs commit
I've tested this intensively, but naturally I can't exclude bugs.
Ralf.
PS.: Most probably, this is the last "Towards automake" patch. The next
one probably will be a real automake patch.

minor step along the way to supporting automake.
