Hi I have RHEL5 running on x86_64 machine, and I need the following packages for the installation of IBM Cell Simulator, and here is what the installation document says: ------------------------------------------------------------------------------------------ . For RHEL 5.1 cross compilation only (X86 and X86_64), you must build and install the compiler sysroot RPMs as described below. That is because these RPMs cannot be provided by SDK and can only be built if you have a RHEL 5.1 license. Follow these steps to build and install the sysroot on an X86 or X86_64 Red Hat Enterprise Linux (RHEL) 5.1 system: Copy the following RHEL 5.1 PowerPC binary packages (from your PPC architecture RHEL 5.1 distribution medium, such as a CD) into the /usr/src/redhat/SOURCES directory: glibc-2.5-18.ppc.rpm glibc-2.5-18.ppc64.rpm glibc-devel-2.5-18.ppc.rpm glibc-devel-2.5-18.ppc64.rpm glibc-headers-2.5-18.ppc.rpm kernel-headers-2.6.18-52.el5.ppc.rpm gmp-4.1.4-10.el5.ppc.rpm gmp-4.1.4-10.el5.ppc64.rpm gmp-devel-4.1.4-10.el5.ppc.rpm gmp-devel-4.1.4-10.el5.ppc64.rpm -------------------------------------------------------------------------------------- I searched for the following packages in the rhn, but I can not find them anywhere. * glibc-2.5-18.ppc64.rpm * glibc-devel-2.5-18.ppc64.rpm * kernel-headers-2.6.18-53.el5.ppc.rpm * gmp-4.1.4-10.el5.ppc64.rpm * gmp-devel-4.1.4-10.el5.ppc64.rpm Can you please help me? Thanks Betül
