Hi,

Trying to compile gcc 4.5.3 I go the following error:

checking whether the GNU Fortran compiler is working... no
configure: error: GNU Fortran is not working; please report a bug in
http://gcc.gnu.org/bugzilla, attaching
/opt/gcc/src/gcc-4.5.3/build/x86_64-apple-darwin11.2.0/libgfortran/config.log
make[1]: *** [configure-target-libgfortran] Error 1
make: *** [bootstrap] Error 2

I'm using:
gcc-4.5.3        
gmp-5.0.2        
mpc-0.9            
mpfr-3.0.1

and configured gcc as:
../configure   --prefix=/opt/gcc   --disable-multilib   --with-gmp=/opt/gcc  
--with-mpfr=/opt/gcc   --with-mpc=/opt/gcc   --enable-languages=c,c++,fortran

See
/opt/gcc/src/gcc-4.5.3/build/x86_64-apple-darwin11.2.0/libgfortran/config.log
in attachment.

Thanks for any help,
Cynthia

Probably PR49738. The llvm-gcc system compiler in Lion miscompiles gmp. If you
run make check in your gmp build, you will see this. Rebuild gmp against clang.
This issue is also fixed in gmp svn.

Also be aware of http://llvm.org/bugs/show_bug.cgi?id=9571. The Xcode 4.x
llvm-gcc still suffers from this bug (although it is fixed in llvm.org's
llvm-gcc 2.9 release) and can't bootstrap FSF gcc. Use clang instead for the
FSF gcc bootstrap as well.

Thanks for the answers. And, indeed, running "make check" for gmp did not work
using llvm-gcc system compiler in Lion. Following
http://beardedcodewarrior.net/2011/07/25/building-gcc-4-6-1-on-mac-os-x-lion/
(using gcc-4.2 installed previously with Snow Leopard instead of llvm-gcc)
makes gmp work.

Cheers,
Cynthia
