Hey,
I want to write an m4 macro which specify the correct AC_ARG_ENABLE
options according to the value ("yes" or "no") of a parameter.
Here is the macro:
dnl use: ECORE_CHECK_MODULE(Foo, default-enabled[, dependancy[,
ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
AC_DEFUN([ECORE_CHECK_MODULE],
[
pushdef([UP], translit([$1], [a-z], [A-Z]))dnl
pushdef([DOWN], translit([$1], [A-Z], [a-z]))dnl
have_ecore_[]DOWN="no"
ecore_[]DOWN[]_cflags=""
ecore_[]DOWN[]_libs=""
ifelse([$2], [no],
[
AC_ARG_ENABLE(ecore-[]DOWN,
[AC_HELP_STRING(
[--enable-ecore-[]DOWN],
[enable the ecore_[]DOWN module. [[default=disabled]]])],
[want_ecore_[]DOWN=$enableval],
[want_ecore_[]DOWN=no])
],
[
AC_ARG_ENABLE(ecore-[]DOWN,
[AC_HELP_STRING(
[--disable-ecore-[]DOWN],
[disable the ecore_[]DOWN module. [[default=enabled]]])],
[want_ecore_[]DOWN=$enableval],
[want_ecore_[]DOWN=yes])
])
AC_MSG_CHECKING(whether ecore_[]DOWN module is to be built)
if test "x$want_ecore_[]DOWN" = "xyes" ; then
if test "x$3" = "x" -o "x$3" = "xyes" ; then
AC_DEFINE(BUILD_ECORE_[]UP, 1, [Build Ecore_$1 Module])
have_ecore_[]DOWN="yes"
ecore_[]DOWN[]_libs="-lecore_[]DOWN"
AC_MSG_RESULT([yes])
else
AC_MSG_RESULT([no (dependancy failed)])
fi
else
AC_MSG_RESULT([no])
fi
AM_CONDITIONAL(BUILD_ECORE_[]UP, test "x$have_ecore_[]DOWN" = "xyes")
if test "x$have_ecore_[]DOWN" = "xyes" ; then
ifelse([$4], , :, [$4])
else
ifelse([$5], , :, [$5])
fi
AC_SUBST(ecore_[]DOWN[]_cflags)
AC_SUBST(ecore_[]DOWN[]_libs)
popdef([UP])
popdef([DOWN])
])
The problem is with
ifelse([$2], [no] *****)
Whatever the 2nd parameter is ("yes" or "no"), it seems that the test
always fails. I try with m4_if, without success too.
Can someone tell me what the proble is ?
thank you
