Thanks for investigating this. I think that we can get away on the Ada side by using the same kludge in tb-gcc.c as in raise-gcc.c:The following fixes PR33608 where we end up installing an unwind.h header that contains a call to abort () which we re-define inside gcc. It happens that ada somewhere includes this re-define without linking to an object that provides fancy_abort, so we'll fail bootstrap with
gcc -static-libgcc -o gnatbind ... ../libcpp/libcpp.a ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -lmpfr -lgmp ada/tracebak.o: In function `_Unwind_GetTextRelBase': /usr/lib/gcc/ia64-suse-linux/4.3.0/include/unwind.h:229: undefined reference to `fancy_abort' collect2: ld returned 1 exit status make[3]: *** [gnatbind] Error 1
fixed by avoiding macro-expansion in unwind-generic.h.
/* We don't want fancy_abort here. */ #undef abort
If that works for you, please install it.
As tb-gcc.c is only included from tracebak.c a better place to #undef abort is probably there.
Like the following. Ok if this passes?
Thanks, Richard.
