System prerequisites

All system prerequisites must be ready on your system before XL C/C++ and its documentation can be successfully installed and run.

Verifying the amount of hard disk space available

You can use the following command to determine the amount of space available in the default installation location (/usr/vacpp/):
df -m /usr
If you plan to install the compiler to a non-default location, you can use the following command:
df -m installation_path
where installation_path represents the non-default location.

Verifying that the required filesets are installed

The following filesets must be installed on your system in order to install IBM XL C/C++ for AIX, V11.1:

Fileset name Fileset description
bos.adt.include Base application development include files
bos.adt.lib Base application development libraries
bos.adt.libm Base application development math libraries
bos.rte Base operating system run time
bos.rte.libc Base application runtime library

At least one of the following locale-specific filesets must be installed on your system:

Fileset name Fileset description
bos.loc.LANG Base locale support
bos.loc.pc.LANG Base system locale PC code set
bos.loc.utf.LANG Base system locale UTF code set
bos.loc.iso.LANG Base system locale ISO code set

You can view information about the installed filesets by using the lslpp command.

Use the following command to determine if the required filesets have been installed:

lslpp -L bos.adt.include bos.adt.lib bos.adt.libm bos.loc.* bos.rte bos.rte.libc
