Monstrous patch from Ralf Corsepius <corsepiu@…>. I have
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  • custom/p4000.cfg seems to be out of date and requires to be reviewed.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 i3456?86-unknown-freebsd2.12? with i3456?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.
  • Property mode set to 100644
