IBM XL Fortran for Linux provides
an interactive utility,
xlf_install,
that walks you through a basic installation. You can use
xlf_install to
perform any of the following tasks:
- Install IBM® XL
Fortran for Linux, V15.1 on
a system where no IBM XL compiler
is currently installed.
- Install IBM XL
Fortran for Linux, V15.1 on
a system and update the XL Fortran runtime library and SMP runtime library
where an older version of IBM XL
compiler is currently installed.
- Install IBM XL
Fortran for Linux, V15.1 on
a system where IBM XL C/C++ for Linux, V13.1 has
already been installed.
In this case, both compilers will use the IBM MASS library provided with IBM XL
Fortran for Linux, V15.1.
For
information about installing IBM XL C/C++ for Linux, V13.1,
refer to the IBM XL C/C++ for Linux, V13.1 Installation
Guide.
- Install an update on a system where IBM XL
Fortran for Linux, V15.1 has
already been installed.
By running the xlf_install utility,
you are prompted to accept or decline the license agreement. If you
accept the agreement, the license files will be output to .txt files
for your future reference. If you decline the agreement, the installation
process exits without installing the compiler and no files will be
written to your system.
You should consider a basic installation of
IBM XL
Fortran for Linux, V15.1 with
the xlf_install utility
on a system as long as
both of the following conditions
apply:
- You are installing the compiler to the default location, /opt/ibm/.
- You are maintaining a single version of the product on your system.
If either of these conditions does not
apply, use the procedures in Advanced installation.
