Basic installation
XL C/C++ provides an interactive utility, xlc_install,
that walks you through a basic installation. You can use xlc_install to do any of the following:
- Install XL C/C++ V8.0 for Blue Gene on a clean system
- Install XL C/C++ V8.0 for Blue Gene to co-reside
with any existing version of XL C/C++ for Linux
- Install XL C/C++ V8.0 for Blue Gene on a system where XL Fortran Advanced Edition V10.1 for Blue Gene is
already installed. In this case, both compilers will use the XL SMP and MASS
libraries provided with XL C/C++ for Blue Gene. (For information about
installing XL Fortran V10.1 for Blue Gene, refer to the XL Fortran Advanced Edition V10.1 for Blue Gene Installation Guide.)
- Install an update on a system where XL C/C++ V8.0 for Blue Gene has
already been installed. In this case, use the procedure in Running the xlc_install utility to update a basic installation.
You should use the xlc_install utility
to install XL C/C++ 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 C/C++ 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 xlc_install utility. Instead,
see the procedures in Advanced installation.
