Verifying that the required GNU and Perl packages are installed

Before you install IBM® XL C/C++ for Linux®, V11.1, you should verify that the required GNU and Perl packages were installed with the operating system.

All required packages can be obtained from your OS's installation media.

For lists of the required packages and version requirements for each supported Linux distribution, see the following:

To verify that the correct versions of the required packages are installed on your system, enter the following command once for each required package:

   rpm -qa | grep package_name

If the package has been installed, this command should return the package's name and version number. The version number must be the same or higher than the version requirement for that package.

Note: If you are installing the compiler onto a system running RHEL 5.5, follow the action described in Could not determine location of 32-bit or 64-bit GCC (RHEL 5.5) to verify that the glibc, glibc-devel, libgcc, libstdc++ and libstdc++-devel packages are installed.
