libgcc @5.1 +universal

[macports@…]

Hi! I would like to install gcc49. As dependency libgcc is build, but it fails with an internal error:

/gensupport.o build/print-rtl.o build/read-md.o build/errors.o ../build-i386-apple-darwin9/libiberty/libiberty.a -lm

I've been installing gcc universal for years, but only on my primary machine, which runs the latest version of OS X (so, 10.10, currently), and it works fine. But I see you're on 10.5. I know gcc installs fine on 10.5, but I haven't tried the universal variant there. Do you really need the universal variant?

I've now tried to install a NON universal version of gcc 4.9 on my OS X 10.5. To do so I first uninstalled alls port with: "port -v uninstall installed", followed by disabling the +universal flag in variants.conf.

The result was, libgcc-5.1 compiled fine, but the gcc 4.9 port fails with following error:

ld: illegal text-relocoation (direct reference) to (global,weak) hash_table<loc_list_hasher, xcallocator>::find_slot_with_hash(dw_loc_list_struct const*, unsigned int, insert_option) in libbackend.a(dwarf2out.o) from anon in libbackend.a(dwarf2out.o) for architecture i386
collect2: error: ld returned 1 exit status
make[3]: *** [f951] Error 1
rm gfortran.pod gcc.pod

I'll also attach the corresponding logfile (main-gcc49.log). If you look at the error, there seems to be a problem with fortran. It is possible to disable the fortran language with some flag?

closing as libgcc is now nothing more than a stub port.
