How to use ACML with gcc 4.6.2 on Redhat to run HPL?

     Since I see this error when trying to use ACML with RHEL 6.2 out of the box:

                   undefined reference to `_gfortran_transfer_integer_write'

     I know I need the newest version of GCC namely 4.6.2. Also I have got gcc 4.6.2, ACML and HPL all working together happily under SUSE on both SLED and SLES. But after trying for several days I can't get past the need of gcc for the thread utilities crti.o crtn.o etc.



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



        but there is a crti.o and crtn.o in



        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?
