Installing an update

An update, or program temporary fix (PTF), of IBM® XL C/C++ for Linux, V13.1 provides a fix or multiple fixes to the product. You can download updates from the support website: http://www.ibm.com/support/entry/portal/product/rational/xl_c/c++_for_linux.

Every PTF update package comes in tar.gz (compressed) format and includes a version of the xlc_install utility that is customized to install only the update that accompanies it. If you have any version (including an earlier update) of IBM XL C/C++ for Linux, V13.1 installed on your system, you can apply the latest update. If you are applying the update to an installation in the default location, follow the procedure in Updating a basic installation using the xlc_install utility. If you are applying the update to an installation in a nondefault location, you must use one of the procedures in Updating an advanced installation. If you want to try out a PTF before installing it, use the procedure in Testing a PTF before you install it.
