Documentation

  • obsoleted The macro AC_DEFINE_DIR provides this functionality directly now.

This macro substitutes (with AC_SUBST) VARNAME with the expansion of itself or the DIR variable if specified, taking care of fixing up ${prefix} and such.

Side effect: VARNAME is replaced with the expansion.

AC_SUBST_DIR bases on Alexandre Oliva's AC_DEFINE_DIR macro.

Examples: 

  AC_SUBST_DIR(DATADIR)
