Synopsis

AC_DEFINE_DIR_(VARNAME, DIR [, DESCRIPTION])

Version

1.1.1.1 (2001/07/26)     0.5.65   :   guidod

Author

Guido Draheim <guidod@gmx.de>, from _AC_DEFINE_DIR by oliva@

Description

This macro _AC_DEFINEs VARNAME to the expansion of the DIR variable, taking care of fixing up ${prefix} and such.

Note that the 3 argument form is only supported with autoconf 2.13 and later (i.e. only where _AC_DEFINE supports 3 arguments).

Examples:

    AC_DEFINE_DIR_(DATADIR, datadir)
    AC_DEFINE_DIR_(PROG_PATH, bindir, [Location of installed binaries])
