You can use the basic installation procedure to install
XL C/C++ if
the following conditions are true:
- You are installing IBM® XL C/C++ for AIX®, V11.1 to
the default directory, /usr/vacpp/.
- You are maintaining a single version of XL C/C++ on
your system, and you agree to remove any previously installed XL C/C++ components.
If both these conditions apply, the basic installation
is the easiest and fastest method, because it can automatically uninstall
previous versions of XL C/C++,
install the latest version, and configure the compiler, all through
the use of a single installation tool.
If either of these conditions does not apply, do not use basic
installation. Instead, see the procedures in Advanced installation.
The following basic installation methods install XL C/C++ to
the default directory. If you have root access or a profile with superuser
privileges, you can use the Bundle
installation method, the System Management
Interface Tool (SMIT), or the installp command to
install the compiler.
You can use the basic installation methods to perform any of the
following tasks:
- Install IBM XL C/C++ for AIX, V11.1 on
a clean system.
- Install IBM XL C/C++ for AIX, V11.1 on
a system where IBM XL Fortran for AIX, V13.1 is
already installed. In this case, both compilers will use the SMP and
MASS libraries provided with XL C/C++ for AIX.
(For information about installing XL Fortran,
see the IBM XL Fortran for AIX, V13.1 Installation
Guide.)
- Install an update on a system where IBM XL C/C++ for AIX, V11.1 has
already been installed. In this case, use the procedure in Update installation.
