xlc_install options
The xlc_install utility provides the following options:
- -h
- Displays the installation utility help page.
- -prefix installation_path
- Explicitly specifies the path to install all the compiler packages. Note: If this option is not used, the default installation location is /opt/ibm/. The C++ runtime package and SMP runtime package will still be installed in /opt/ibmcmp/ as previous versions for backward compatibility.
- -rpmloc rpmlocation_path
- Explicitly specifies the path where all compiler packages are located. The default rpmlocation_path is ./images-x86/rpms or ./images/rpms, which is relative to the path of the installation tool.
- Note: For most users, the -rpmloc rpmlocation_path option is not required in the installation invocation. If you use the utility directly from the DVD or the electronic image, it will automatically determine the source location of the packages.
- -U
- Updates the compiler to the Version.Release.Modification.Fix-Build (V.R.M.F-B) level that the installation utility version supports. For more information, see Updating a basic installation using the xlc_install utility.
- Note: The -U option cannot update the compiler to a different Version.Release.Modification (V.R.M) level.
- -v
- Displays debugging information generated during the installation of the compiler.
- -vv
- Displays extra debugging information generated during the installation of the compiler.
