|
|
dnl
|
|
dnl This macro defines (with AC_DEFINE) VARNAME to the expansion of the DIR
|
|
dnl variable, taking care of fixing up ${prefix} and such.
|
|
dnl
|
|
dnl Note that the 3 argument form is only supported with autoconf 2.13 and
|
|
dnl later (i.e. only where AC_DEFINE supports 3 arguments).
|
|
dnl
|
|
dnl Examples:
|
|
dnl
|
|
dnl AC_DEFINE_DIR(DATADIR, datadir)
|
|
dnl AC_DEFINE_DIR(PROG_PATH, bindir, [Location of installed binaries])
