Further preparations for autoconf > 2.52:
* aclocal/enable-inlines.m4: Use AS_IF instead of if/then/else.
* aclocal/quoting.m4: Use `eval echo $ac_args` to unquote $ac_arg.
* aclocal/target.m4: Use `eval echo $rtems_args` to unquote $ac_arg.
* aclocal/enable-bare.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-cxx.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-inlines.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-itron.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-multiprocessing.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-networking.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-posix.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-rdbg.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-rtemsbsp.m4: Improve quoting of AC_HELP_STRING.
* aclocal/enable-tests.m4: Improve quoting of AC_HELP_STRING.
(autoconf > 2.54 seems to have problems with the old form of
quoting).
that is a somewhat experimental, multilib-related patch:
Changes:
* Use RTEMS_ENV_RTEMSCPU instead of RTEMS_ENV_RTEMSBSP in
configure.ins below exec/.
At the moment, RTEMS_ENV_RTEMSCPU is more or less an optical change
to emphasize that these subdirectories shall not depend on RTEMS_BSP
than a real behavioral change.
* Add AC_DEFINE_* to several aclocal/*.m4 macros to prepare
autoheader/autoconf generated targopts.h and similiar configuration
headers.
* c/src/configure.in: remove exec from cfg_subdirs if multilibs are
enabled (c/src is build per bsp, exec shall be build per cpu in c/
or from the toplevel in future, when multilibs are enabled.)
Notes:
* This patch should not have any impact on the current building scheme.
* --enable-multilib still does not work.
* running bootstrap from the toplevel directory is required.

CVS: ----------------------------------------------------------------------
Yet some more modifications, I would recommend to be considered before
releasing a snapshot:
1. Cleanup to aclocal/
cvs rm -f aclocal/cygwin.m4
cvs rm -f aclocal/exeext.m4
They are neither used nor needed anymore, however they also don't
disturb (we use autoconf-2.13's AC_EXEEXT instead, now)
----------
2. rtems-rc-19990328-0.diff
Some (minor) bug-fixes:
* make/Templates/Makefile.inc.in: use the new installation directory
($(prefix)/ instead of $(prefix)/rtems/)
* c/src/exec/score/tools/generic/Makefile.am: added line to include local.am
* c/src/exec/score/tools/*/configure.in: added CVS Id header
----------
3. rtems-rc-19990328-1.diff
Enhancements and cleanups to autogen, rtems-polish.sh, configure.in etc.
* autogen: Use the file "VERSION" to detect RTEMS toplevel directory,
extended usage-message, use "find -print"
* c/update-tools/cipolish: New script to beautify configure.in scripts
* c/update-tools/rtems-polish.sh: Use the file "VERSION" to detect RTEMS
toplevel directory, extended usage-message, added variable for perl
scripts' subdirectory, use "find -print", cipolish support, new options
-ac -am -ci.
* aclocal/*.m4, configure.in: moved some AC_SUBST lines to aclocal/*.m4
(reduces size of configure.in
scripts, eases splitting configure.in scripts).
----------
This is the first real automake patch.
It adds automake support to c/build-tools and cleans up a few minor
issues.
I consider this to be a testing probe to examine problems with automake.
Therefore, this patch is just a more or less harmless replacement of the
former RTEMS Makefiles and I expect it not last for long. If you want to
give automake Makefiles a public try and if you want/need to learn about
problems with it, then it's about time for a new snapshot, IMO. I may
have screwed up something not directly related to automake, but I expect
very few (none to be precise) problems with automake. However, somebody
should at least try building on Cygwin. If you feel a bit more
adventureous, then I also can continue to submit more patches.
[FYI: I still have a couple of automake files laying around, but they
need some cleanup before being submitted as patches. Now, that I am just
into it, I'll perhaps submit another one tonight :-]
After applying this patch (patch -p1 -E <
<path-to>/rtems-rc-19990318-0), first run the "autogen" script from the
toplevel source directory, before committing to CVS. Be careful about
dependencies between Makefile.am and Makefile.ins when cutting tarballs
from CVS. Makefile.ins are required to be newer than Makefile.ams,
otherwise users would need to have automake, autoconf and perl. Some
people recommend to "touch" all Makefile.in after checkout from cvs (cf.
egcs/contrib/egcs_update).
ATTENTION:
* This patch adds a number of new files.
* remove aclocal/exeext.m4 and aclocal/cygwin.m4 from CVS, They are now
covered by autoconf-2.13`s AC_EXEEXT.
Some features/side-effects which are probably interesting for you:
In a configured build-tree "cd c/build-tools", then try
* "make RTEMS_BSP=<bsp> install"
* "make RTEMS_BSP=<bsp> dist"
OK, I 've made up my mind to cut a big chunk of my automake-patches (:-).
Below you can find a drop-in replacement of the aclocal directory. It
contains a lot of new macro files, most of them are directly cut from rtems
top-level configure script, some are new some are identical to former
versions. The motivation behind these files is to reuse parts from rtems
current top-level configure.in script in up-coming subdirectory configure.in
scripts.
I'd like to ask you to untar the archive ontop of the source tree and to
add/commit these files to CVS. Adding these files should not have any
influence on RTEMS momentary configuration (except of you are required to
run aclocal -I aclocal && autoconf afterwards), because most of them
currently are not used at all.
---------
BTW: Please upgrade to autoconf-2.13 and automake-2.4, if you havn't done
this already (egcs/CVS require them, too). My upcoming automake files
require automake-2.4 which requires autoconf-2.13 or later.
