I'm trying to get PPC going again with kbuild-2.5, but I'm runnign into some wierd errors. Anyone know what would cause the .tmp_targets rule to fail with an error 139? If I change: 139 = 128+11 - sig 11 - SEGV. Probably pp_makefile2 is breaking. cd $KBUILD_OBJTREE source .tmp_env (sets the environment variables, except src/object) gdb scripts/pp_makefile2 r Where does it break? What is the backtrace? It was on a for loop over arch_head. If I put arch_head in arch/ppc/Makefile.defs.noconfig, I got to the point of finding (I think) problems w/ my Makefile.in's. Is it possible to set arch_head in arch/$(ARCH)/Makefile.defs.config? I get to the point of kbuild-2.5 telling me there's no rule to make target 'installable'. That makes no sense. Even without selecting a kernel format, the installable target is defined to be at least System.map. Check .tmp_global_makefile, find installable:, it should look like this. It didn't make sense to me either, so I'll assume that w/ the prior breakage things just went horrible. -- Tom Rini (TR1265) http://gate.crashing.org/~trini/ ___ kbuild-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/kbuild-devel
Re: [kbuild-devel] .tmp_targets failing?
arch_head must be defined in arch/$(ARCH)/Makefile.defs.noconfig. The
value of arch_head is used by pp_makefile2 to generate the global
makefile, Makefile.defs.config is not read until after the global
makefile is created, in fact Makefile.defs.config is only read by the
global makefile.
There is a bug in pp_makefile2.c, trim_arch_head() assumes that
arch_head is always set to at least one string. If you really need an
empty arch_head, change trim_arch_head() from
for (a = arch_head; *a; ++a) {
to
for (a = arch_head; a *a; ++a) {
