Configuring XL C/C++ V8.0

After installing and trying out XL C/C++ V8.0, you might need to re-configure the compiler.

The new_install utility automatically backs up any existing configuration file and invokes the vac_configure utility. Before you can run new_install, you must have root or administrator privileges.

For instructions, see Running the new_install utility.

You should invoke the vac_configure utility directly only when at least one of the following is true:

For instructions, see Running the vac_configure utility directly.

Note:
If you configure the compiler using vac_configure, your output configuration file, vac.cfg, can be written to any location where you have write permission. You would not need root or administrative privileges.
