Using IBM XL C/C++ for Linux, V13.1.5 with the Advance Toolchain

IBM® XL C/C++ for Linux, V13.1.5 supports IBM Advance Toolchain 9.0, which is a set of open source development tools and runtime libraries. With IBM Advance Toolchain 9.0, you can take advantage of the latest POWER® hardware features on Linux, especially the tuned libraries. For more information about the Advance Toolchain 9.0, see IBM Advance Toolchain for PowerLinux™ Documentation.

To use IBM XL C/C++ for Linux, V13.1.5 with the Advance Toolchain, take the following steps:

1. Install the at9.0 packages into the default installation location. For instructions, see IBM Advance Toolchain for PowerLinux Documentation.
2. Run the xlc_configure utility to create the xlc.at.cfg configuration file. In the xlc.at.cfg configuration file, all other entities except the XL C/C++ compiler are directed to those of the Advance Toolchain. The entities include the linker, headers, and runtime libraries.
   Note: To run the xlc_configure utility, you must either become the root user or use the sudo command.
   • If you installed the compiler in the default location, issue the following command:

     xlc_configure -at

   • If you installed the compiler in a nondefault installation (NDI) location, issue the following command:

     xlc_configure -at -ibmcmp $ndi_path

     where $ndi_path is the directory in which you installed the compiler.
3. Invoke the XL compiler with the Advance Toolchain support.
   • If you installed the compiler in the default location, issue the following commands:

     /opt/ibm/xlC/13.1.5/bin/xlc_at
     /opt/ibm/xlC/13.1.5/bin/xlC_at

   • If you installed the compiler in an NDI location, issue the following commands:

     $ndi_path/xlC/13.1.5/bin/xlc_at
     $ndi_path/xlC/13.1.5/bin/xlC_at
