To install
XL Fortran V10.1 to co-reside with earlier versions
of
XL Fortran on the same system, you have the following options:
- You can install multiple versions in the same location, while forcing
all versions to use the most recent runtime environment. This option is recommended
if you want to continue using the different versions of XL Fortran over
the long term. Multiple versions of XL Fortran can co-reside in the same
location as long as the later version does not attempt to use runtime packages
that pre-date it. If your existing version is installed in the default location,
do not try to use xlf_install to install the additional
version; it will remove the old files for you. Instead, use the procedure
in Installing XL Fortran V10.1 to co-reside with earlier versions in the same location
- You can allow each version to use the runtime environment that was shipped
with it. This option is recommended if you want to phase a migration to the
later version. In this case, you will need to install XL Fortran V10.1 in
a separate location from all other versions of XL Fortran.
To do so, follow one of the procedures in Installing XL Fortran to a non-default location (for advanced users).
