Basic installation
XL Fortran provides an interactive utility, xlf_install,
that walks you through a basic installation. You can use xlf_install to do any of the following:
- Install XL Fortran V10.1 for Blue Gene on a clean system
- Install XL Fortran V10.1 for Blue Gene to co-reside
with any existing version of XL Fortran for Linux
- Install XL Fortran V10.1 for Blue Gene on a system where XL C/C++ Advanced Edition V8.0 for Blue Gene is
already installed. In this case, both compilers will use the XL SMP and MASS
libraries provided with XL Fortran for Blue Gene. (For information about
installing XL C/C++ V8.0 for Blue Gene, refer to the XL C/C++ Advanced Edition V8.0 for Blue Gene Installation Guide.)
- Install an update on a system where XL Fortran V10.1 for Blue Gene has
already been installed. In this case, use the procedure in Running the xlf_install utility to update a basic installation.
You should use the xlf_install utility
to install XL Fortran as long as all of the
following conditions apply:
- You are installing the compiler to the default
location, which is /opt/ibmcmp/.
- You agree to remove any previously installed XL Fortran for Blue Gene components.
- The Blue Gene tool chain is installed in the default
location, /bgl/BlueLight/ppcfloor.
If any of these conditions does not apply, do not use the xlf_install utility. Instead,
see the procedures in Advanced installation.
