Gcc 4.6.2 can't find crti.asm crtn.asm for AMD Opteron

[Thomas Bodine]

I am trying to build HPC High Performance Linpack .

    I have figured out how to build it on SUSE. On Suse I must build
    a complete gcc 4.6.2 compiler from the ground up. Then ACML,
    openMPI, and HPL.

    When I build gcc, for each package I run configure with these arguments:
        parentDir=where I want to put it like /opt or /usr/local
        export LD_LIBRARY_PATH="$parentDir/lib:/usr/local/lib:/lib"
        export PATH=$parentDir/bin:$PATH
        dirArgs="--prefix=$parentDir --exec-prefix=$parentDir"
        gmpArgs="--with-gmp-include=$parentDir/include/ --with-gmp-lib=$parentDir/lib"
    The dirArgs are used for every package, the gmpArgs are used only for
    the packages that need GMP.

    I have a problem compiling HPL under RedHat:

        1. If I try compiling in the same way I do under SUSE, I see
            "cannot find crti.o" and "cannot find crtn.o" from
            $parentDir/x86_64-unknown-linux-gnu/bin/ld

        but there is a crti.o and crtn.o in
            /usr/lib/x86_64-redhat-linux5E/lib64

        I suspect gcc is trying to compile 32 bit even though I used
        this command when configuring gcc:
        ./configure --prefix=$parentDirectory --exec-prefix=$parentDirectory \
        --with-gmp-include=$parentDirectory/include/ --with-gmp-lib=$parentDirectory/lib --with-multilib-list=m64

        2. So then I tried compiling libc where I get this error:
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find crt1.o: No such file or directory
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find crti.o: No such file or directory
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find crtbegin.o: No such file or directory
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find -lgcc
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find -lgcc_s
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find -lgcc
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find -lgcc_s
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find crtend.o: No such file or directory
            $parentDir/x86_64-unknown-linux-gnu/bin/ld: cannot find crtn.o
                    
        And try as I  might I can't seem to find a crtl.asm crti.asm
        crtend.asm for X86_64 or in my case AMD Opteron.            

        What do I do next?
