gmp - mac os x

[Fred Mesnard]

Hi! 
I tried to compile GMP 4.1 on Mac OS X, I got kind
help from guys of the Fink Project. Here's a summary.
Best regards,
Fred

Not related, totally different thing. libtool comes with the app.

So why are you here? :)

Anyway, i tried adding --enable-cxx to the fink info file's configure. It outputs:

checking whether the g++ linker (/usr/bin/ld) supports shared libraries... no
..
checking whether the g++ linker (/usr/bin/ld) supports shared libraries... no
checking whether -lc should be explicitly linked in... yes


It looks like half of GMP's configure script is from an old version of libtool, and half is from the new. Or somethng like that. The whole archive_cmds_CXX is missing for darwin.  It has the (updated, with flat namespace) part for flat_namespace, but no archive_cmds_CXX for darwin. It looks like it should work fine if i just copy the archive_cmds to the archive_cmds_CXX. And indeed, it does:

This lets it link:

So drm, you can add this patch and --enable-cxx to GMP, and we get:
/sw/include/gmpxx.h
/sw/lib/libgmpxx.3.0.2.dylib
/sw/lib/libgmpxx.a
/sw/lib/libgmpxx.la
/sw/lib/libgmpxx.3.dylib
/sw/lib/libgmpxx.dylib

THANK YOU Ben, you're right! I rebuilt from scratch  GMP 4.1
with the new configure, CPPFLAGS=-fexceptions,
and the --enable-cxx option.
Here's the result of 'make check'. Everything is ok up to:
