System prerequisites

Ensure that your system meets all prerequisites before installing the product. Failure to meet the prerequisites will cause the installation or configuration of the compiler to fail.

The following are the requirements for installing IBM® XL C/C++ for Linux, V13.1:

  • Operating system: You can use one of the following operating systems supported by the IBM Power Systems™ servers:
    • Red Hat Enterprise Linux 6.4 (RHEL 6.4)
    • Red Hat Enterprise Linux 6.5 (RHEL 6.5)
    • Red Hat Enterprise Linux 6.6 (RHEL 6.6)
    • Red Hat Enterprise Linux 7.0 (RHEL 7.0)
    • SUSE Linux Enterprise Server 11 Service Pack 2 (SLES 11 SP2)
    • SUSE Linux Enterprise Server 11 Service Pack 3 (SLES 11 SP3)
  • Hardware:

    You can use any IBM Power Systems server as long as it is supported by your operating system distribution. For a complete list of the IBM Power Systems servers, see http://www.ibm.com/systems/power/hardware/.

  • Storage:
    • Approximately 200 MB for product packages
    • Minimum of 2 GB hard drive space for paging
    • Minimum of 512 MB for temporary files
    Note: High levels of optimization can require more space for paging and temporary files.

    To verify that you have enough hard disk space available, see Verifying the amount of hard disk space available.

  • Required software:

    To determine which GNU and Perl packages are required to run the compiler on your operating system, consult the relevant table below. To verify that the required packages are installed, see Verifying that the required GNU and Perl packages are installed.

Note: Packages marked with an asterisk (*) must be available in both 32-bit and 64-bit versions.
