Hello All,

I just noticed (on Debian/Testing/AMD64) that with both polyml-5.4 & latest SVN trunk (i.e. rev 1215) it is not possible to use binutils gold linker.

I configured with ./configure CC='gcc-4.5' CXX='g++-4.5'

Where gcc-4.5 is an GCC 4.5.1 from FSF tree: % gcc-4.5 -v Using built-in specs. COLLECT_GCC=/usr/local/bin/gcc-4.5 COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.5.1/lto-wrapper Target: x86_64-unknown-linux-gnu Configured with: /usr/src/Lang/gcc-4.5.1/configure --enable-plugins --program-suffix=-4.5 --enable-languages=c,c++,objc,lto --enable-checking=release

Build fails with /bin/bash ./libtool --tag=CC --mode=link gcc-4.5 -Wall -fno-strict-aliasing -O3 -o poly polyexport.o libpolymain/libpolymain.la libpolyml/libpolyml.la -lpthread -lgmp -lm -ldl -lstdc++ -lgcc_s -lgcc libtool: link: gcc-4.5 -Wall -fno-strict-aliasing -O3 -o .libs/poly polyexport.o libpolymain/.libs/libpolymain.a libpolyml/.libs/libpolyml.so -lpthread /usr/lib/libgmp.so -lm -ldl /usr/local/lib/../lib64/libstdc+ +.so -lgcc_s -lgcc -Wl,-rpath -Wl,/usr/local/lib/../lib64 /usr/bin/ld: error: polyexport.o: unsupported REL reloc section /usr/bin/ld: internal error in relocate_section, at ../../gold/x86_64.cc:2444 collect2: ld returned 1 exit status

By the way, polyml cannot be build with CC='gcc-4.5 -flto' CXX='g++-4.5 -flto' that is using the new link time optimization feature of GCC (which requires binutils GOLD).

Regards.
