Hey,
i would like to use AS_HELP_STRING in an m4 macro such that the
description of the help is different according to the value of one
parameter. The macro is the following:
dnl use: ECORE_CHECK_MODULE(Foo, default-enabled[, dependancy[, ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
AC_DEFUN([ECORE_CHECK_MODULE],
[
m4_pushdef([UP], m4_toupper([$1]))dnl
m4_pushdef([DOWN], m4_tolower([$1]))dnl
want_module=$2
if test "x${want_module}" = "xyes" ; then
wanted_value="enabled"
else
wanted_value="disabled"
fi
AC_ARG_ENABLE([ecore-]m4_defn([DOWN]),
[AS_HELP_STRING(
[--enable-ecore-[]m4_defn([DOWN])],
[enable the ecore_]m4_defn([DOWN])[ module. @<:@default=$wanted_value@:>@])],
[want_module="$enableval"],
[want_module="no"])
AC_MSG_CHECKING([whether ecore_]m4_defn([DOWN])[ module is to be built])
AS_IF([test "x$have_ecore_[]m4_defn([DOWN])" = "xyes"], [$4], [$5])
m4_popdef([UP])
m4_popdef([DOWN])
])
What is displayed by --help is:
--enable-ecore-job enable the ecore_job module. [default=$wanted_value]
I've searched a lot, tried a lot of things, nothing worked and i have no
more idea.
can someone help me ?
