Default installation (AIX)

Edit online

The default installation procedure installs IBM® Open XL Fortran for AIX® 17.1.0 on an AIX system, to the default directory, /opt/IBM/openxlf/17.1.0/.

The default 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 default installation to install IBM Open XL Fortran for AIX 17.1.0, any previous version of the XL compiler will not be uninstalled. However, the C++ runtime library, the Fortran runtime library, and the shared-memory parallelism (SMP) runtime library will be migrated to the new versions.

You can use the following methods to perform default installation procedure:
You can use the default installation methods to perform any of the following tasks:
  • Install IBM Open XL Fortran for AIX 17.1.0 on a clean system.
  • Install IBM Open XL Fortran for AIX 17.1.0 on a system that has a previous version of the XL compiler installed. In this case, both compilers will use the Fortran runtime library and the SMP runtime library provided with IBM Open XL Fortran for AIX 17.1.0.
  • Install IBM Open XL Fortran for AIX 17.1.0 on a system where IBM XL C for AIX 13.1.3 or Open XL C/C++ for AIX 17.1.0 is already installed. In this case, both compilers will use the SMP and MASS libraries provided with IBM Open XL Fortran for AIX. (For information about installing Open XL C/C++, see the IBM XL C for AIX 13.1.3 or Open XL C/C++ for AIX 17.1.0 Installation Guide.)
