You can use the basic installation procedure to install XL C/C++ if you are installing IBM® XL C/C++ for AIX®, V13.1 to the default directory, /opt/IBM/xlC/13.1.0/.
The basic installation is the easiest and fastest method because it can install the latest version and configure the compiler, all through the use of a single installation tool.
If you are using the basic installation to install IBM XL C/C++ for AIX, V13.1, any previous version of the XL compiler will not be uninstalled. However, the C++ runtime library and the shared-memory parallelism (SMP) runtime library will be migrated to the new versions.
If you are not installing IBM XL C/C++ for AIX, V13.1 to the default directory, do not use basic installation. Instead, see the procedures in Advanced installation.
The following basic installation methods install XL C/C++ to the default directory. If you have the root access or an account with superuser privileges, you can use the Bundle installation method, the System Management Interface Tool (SMIT), or the installp command to install the compiler.
