Preparing a PTF package for installation

Updates to the compiler are supplied as PTF packages. Before these PTF packages can be used to update the compiler, they must be downloaded and uncompressed, and a .toc file must be generated.

Use the following instructions to prepare the update package for installation:
Note: You must be logged in as root or have superuser authority.
  1. Download the desired PTF package (for example vacpp.111.aix.mthyear.ptf.tar.Z) into an empty directory.
  2. Restore the compressed file and extract the PTF filesets from the downloaded package:
    1. To uncompress the file, use the command
      uncompress package_name.tar.Z
    2. To unpack the resulting tar file, use the command
      tar -xvf package_name.tar
  3. Use the command inutoc directory_name to generate a .toc file in the same directory as the unpacked filesets.
The following example shows the steps to prepare the package, vacpp.111.aix.mthyear.ptf.tar.Z, located in the new directory, /compiler/update/ for installation.
cd /compiler/update
uncompress -f vacpp.111.aix.mthyear.ptf.tar.Z
tar -xvf vacpp.111.aix.mthyear.ptf.tar
inutoc .
