made no attempt to divide the comments up and place them with just
the appropriate files. Here is an excerpt from Ralf's email:
Changes including comments on changes I made after cycling through
all the targets:
* Added ranlib support. Now all targets use "ranlib" instead of "ar -s"
to build an index for a library. If ranlib isn't detected during
configuration, check if ar -s is working and try "ar -s" instead of
* Removed $(XXX_FOR_TARGET) from make/target.cfg.in, use $(XXX) instead now.
* gcc-target-default.cfg: LINK_XXXX-defines reworked to solve the -l
problem under posix (cf gcc-target-default.cfg)
* rtems-glom replaced by Makefile-rules inside of the wrapup/Makefile.in
that has been using rtems-glom until now.
* Removed CCC and friends in gcc-target-default.cfg, as they have been
breaking CXX support.
* Removed CONFIG.$(TARGET_ARCH).CC lines from several custom/*.cfg
files, because this is now set in custom/default.cfg.
* Added aclocal/ar-s.m4, check whether "ar -s" is working
* Added aclocal/cygwin.m4 and aclocal/exeext.m4.
* Reworked aclocal/canonicalize-tools.m4: Added ar -s check; fixes for
problems when XXX_FOR_TARGET is given via environment variables (didn't
work for gcc until now), adding cygwin check, improved autoconf-cache
handling.
* Removed -l from make rule dependencies. LINK_LIBS is now allowed to
contain -L and -l. LINK_OBJS and LINK_FILES must not contain -L or -l.
gcc28 make-exe rules now link using $(LINK_OBJS) $(LINK_LIBS) => Almost
all custom/*.cfg are modified. This is very likely to break something
because of typos or having missed to edit a file.
Open problems, known bugs, things I didn't do:
* custom/p4000.cfg seems to be out of date and requires to be reviewed.
(JRS NOTE: It is subordinate p4650 and p4600 -- both of which build ok
after minor changes.)
* custom/psim.cfg needs to be reviewed, I added some changes to it, I am
insecure about.
(JRS NOTE: psim had a minor problem endif/endef swapped but runs fine.)
* rtems-glom.in can now be removed.
* gcc*.cfg files "make depend" rules don't honor language specific flags
(e.g CXXFLAGS is ignored for *.cc) - Nothing to worry about now, but may
cause problems for hosts/targets not using gcc or rtems-add-ons that use
external packages.
* AFAIS, the no_bsp BSP can't be build anymore, i.e. configure refused
to configure for it whatever I tried.
* The toplevel and toplevel+1 README files are quite out-dated
* cygwin.m4 isn't of much use for rtems. In most cases (cf.
aclocal/*.m4) it is worked around by directly using $host_os. I think
I'll remove it soon after the next snapshot
* Before release the cygwin patch needs to be tested under cygwin. I may
have broken/missed something (esp. the sed-pattern to convert \\ into /
may be broken).
* You should try to build/run the posix-BSP under solaris - I don't
expect problems, but I am not 100% sure, esp. with regard to ranlib/ar -s.
* You should consider to convert all make/compilers/*.cfg files into
make/compilers/*.cfg.in files and let autoconf generate the *.cfg. This
may help getting rid of some if/then/else statements and help
hard-coding some defines into those files in future and shouldn't
disturb now.
* Not having installed libc.a/libm.a on a host may still break building
rtems, esp. when using -disable-gcc28 as the gcc27-configuration scheme
directly accesses libc.a and libm.a. The problem should not appear when
using gcc28 because it references libc/libm only through -lc and -lm
which may be static or dynamic (I didn't test this).
* shgen is not yet included (I didn't yet have enough time to integrate it).
* I know about a few more configure-probs (esp. cross-checking
--enable-* flags).
+ warn/refuse to configure when --enable-libcdir and
--enable-gcc28 are given.
+ force --enable-libcdir when --disable-gcc28 is given
* Replaced KSHELL with @KSH@ in some shell scripts generated by configure.in.
* Added a dependency to aclocal/*.m4 in the toplevel Makefile => configure
and aclocal.m4 will now be rebuild when any aclocal/*.m4 file is changed
* Some changes to aclocal/gcc-pipe.m4 and aclocal/gcc-specs.m4
* Replaced i[[3456]]86-unknown-freebsd2.[[12]] with i[[3456]]86-*freebsd2.*
in configure.in, as I suppose there might exist a variety of valid vendors
(2nd field of the name-tripple)
* Disabled override MAKEFLAGS in toplevel Makefile.in - Potential
side-effects are not really clear to me.
* In mvme162.cfg, $(LINK_LIBS) is missing in the CC line in gcc28's make-exe
rule (yet another one I missed to edit). Just append $(LINK_LIBS) to
the "CC" line, like I hopefully did to ALL other custom/*.cfg files.
* the problem with mvme162lx.cfg is a follow-up problem of the
mvme162.cfg-bug.
* mvme162/console and idp/console had variables named Buffer which
conflicted with similarly named variables in some tests.

Here is the result of my nightly work to get RTEMS_ROOT=$srcdir working
with different shells and relative/absolute paths.
What I did is relatively simple in principle:
Instead of setting RTEMS_ROOT in configure.in and then let configure
substitute @RTEMS_ROOT@ inside the Makefiles, I now let each Makefile
set RTEMS_ROOT from each Makefile's @top_srcdir@ value.
The difference is subtile, but with enormous side effects:
- If RTEMS_ROOT is set in configure, then the same single value will be
propagated to all Makefiles. This breaks using relative paths, as the
relative path to the root of the source tree is used inside of all
subdirectory Makefiles.
- Now each Makefile.in sets RTEMS_ROOT = @top_srcdir@. top_srcdir is
computed individually by configure for each single Makefile.in, hereby
receiving the correct value, no matter if relative or absolute paths are
used.
To get this working, I needed to remove setting RTEMS_ROOT from
target.cfg.in, because this overrides the value of RTEMS_ROOT from each
individual Makefile.
Furthermore, I removed RTEMS_CUSTOM from the Makefiles and replaced all
"include $(RTEMS_CUSTOM)" directives with"include
$(RTEMS_ROOT)/make/custom/$(RTEMS_BSP)". Perhaps you don't like this,
but I think, to have one variable less is clearer and easier to
understand than having several variables refering to the next one.
I enclose a small patch to this mail, which
- fixes the config.h problem (to finally clearify misunderstands)
- removes assignment/subsitution of RTEMS_ROOT from configure.in
- contains a workaround for the application Makefile's RTEMS_ROOT
problem (reported by Eric)
- removes some unused lines from the toplevel Makefile.in
- removes assignment of RTEMS_ROOT from make/target.cfg.in

Now that you have asked -- I'll attach a list of files lacking an RCS-Id to
this mail. This list has been generated by a little sh-script I'll also
enclose.

any directory in the build tree. The only variable which must be set
before the command "gmake" is invoked is RTEMS_BSP (e.g. RTEMS_BSP=erc32).
