I am trying to build gcc-4.2.2 for sparc-sun-solaris2.9, but the build seems to
require 32-bit gmp and mpfr in addition to 64-bit gmp and mpfr. I have built
these 32-bit dependencies, but have already used the "--with-gmp" and
"--with-mpfr" to point to the 64-bit libraries. Questions: Is it true that a
native bootstrap build of gcc-4.2.2 this on this platform will require both 32
and 64-bit gmp and mpfr? If so, how can I specify these additional locations?
I have tried setting "--with-gmp" to the 32-bit location and "--with-mpfr" to
the 64-bit location. Perhaps this would have worked, except that at points
where f951 gets invoked, it can not find its dependencies because
LD_LIBRARY_PATH gets stripped out of its calling environment. I keep wishing I
could get RUNPATHs embedded to avoid this problem.
I did succeed in building gcc-4.2.2 on this host (notes on this forthcoming),
but only by employing a nasty hack which forced every compiled binary to
64-bit:
GCC_FOR_TARGET = $(STAGE_CC_WRAPPER) ./xgcc -m64 -B./
-B$(build_tooldir)/bin/ -isystem $(build_tooldir)/include -isystem
$(build_tooldir)/sys-include -L$(objdir)/../ld
The resulting gcc, of course would only work if I used the -m64 flag for
everything.
Currently, the build fails with the following error. with the following error:
