-- 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
./autogen
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
