> Could you check what compiler_lib_search_path is set to inside the
generated libtool in the fplll build directory? ({{{grep
compiler_lib_search_path= src/libtool}}})
Yes, sure.
Since posting this, I recompiled gcc and put it in the prefix
{{{
/usr/local/gcc-4.4.4-multilib
}}}
so the output from the build process is different to above. Here is the
output, which is achieved when CFLAGS, CXXFLAGS, CPPFLAGS and LDFLAGS all
have the option "-m64" addded.

Here is the output you requested.

If I manually add
{{{
-L /usr/local/gcc-4.4.4-multilib/lib/amd64 -R
/usr/local/gcc-4.4.4-multilib/lib/amd64
}}}
to CFLAGS, CXXFLAGS etc, so this will link properly. But it should not be
necessary to do this.
I sent this problem via email today to the three developers listed in
src/README.
