Hi, I need to build gcc-4.3.4 on non-standard location (NFS mounted). I configured: $../gcc-4.3.4/configure --prefix={insall dir} --with-gmp={install dir} --with-mpfr={install dir} --with-local-prefix={install dir} --disable-shared I ran make -j1. But I keep getting: checking for suffix of object files... configure: error: cannot compute suffix of object files: cannot compile In x86_64-unknown-linux-gnu/libgcc/config.log, I can see: /home/panthdev/apps/gcc-4.3.4-compliant/compiler/objdir/./gcc/cc1: error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory libmpfr.so.1 is there in {install dir}/lib. Also if I set LD_LIBRARY_PATH to {install dir}/lib, then it finds the libmpfr.so.1 but config.log starts complaining: /tmp/cce9YhFK.s: Assembler messages: /tmp/cce9YhFK.s:16: Error: bad register name %rbp' /tmp/cce9YhFK.s:18: Error: bad register name%rsp' Please help. Thanks in advance. -AK
