The compiler invocation commands are not automatically installed in /usr/bin/. To invoke the compiler without having to specify the full path, create a shortcut to the invocation commands.
To create a shortcut to the XL C/C++ invocation commands, do one of the following:
Example:
ln -s /usr/vacpp/bin/xlc /usr/bin/xlc
Example:
PATH=$PATH:/usr/vacpp/bin/
export PATH
For example, if you installed XL C/C++ to the /compiler/xlcpp directory, you would run the commands:
PATH=$PATH:/compiler/xlcpp/usr/vacpp/bin/ export PATH
