Here is the standard hierarchy of paths, as defined by the GNU Coding Standards:
prefix exec_prefix bindir libdir libexecdir sbindir datarootdir docdir infodir htmldir dvidir psdir pdfdir localedir datadir (only for autoconf >= 2.59c) infodir (only for autoconf >= 2.59c) mandir (only for autoconf >= 2.59c) lispdir (only for autoconf >= 2.59c) datadir (only for autoconf < 2.59c) infodir (only for autoconf < 2.59c) mandir (only for autoconf < 2.59c) lispdir (only for autoconf < 2.59c) sysconfdir sharedstatedir localstatedir runstatedir (only for autoconf >= 2.70) includedir oldincludedir
This macro will setup a set of variables of the form ’xxx_forward_relative_path’ and ’xxx_backward_relative_path’ where xxx is one of the above directories. The latter variable is set to the relative path to go from xxx to its parent directory, while the former hold the other way.
For instance ‘bindir_relative_path’ will contains the value to add to $exec_prefix to reach the $bindir directory (usually ’bin’), and ‘bindir_backward_relative_path’ the value to append to $bindir to reach the $exec_prefix directory (usually ’..’).
This macro requires AX_COMPUTE_RELATIVE_PATHS which itself requires AX_NORMALIZE_PATH.
