common/hooks/post-install/80-prepare-32bit.sh

   1 # This hook creates a new PKGDESTDIR with 32bit files for x86_64.
   2 #
   3 # Variables that can be used in templates:
   4 #       - lib32depends: if set, 32bit pkg will use this rather than "depends".
   5 #       - lib32disabled: if set, no 32bit pkg will be created.
   6 #       - lib32files: additional files to add to the 32bit pkg (abs paths, separated by blanks).
   7 #       - lib32symlinks: makes a symlink from lib32 to lib of the specified file (basename).
   8 #       - lib32mode:
   9 #               * if unset only files for libraries will be copied.
  10 #               * if set to "full" all files will be copied.
