How can I enable option-checking from configure.ac after it being default-disabled?

Hi. I don't see a way to turn on option-checking after it being disabled-by-default due to AC_CONFIG_SUBDIRS. I had expected to find either an option to AC_DISABLE_OPTION_CHECKING, e.g. something like AC_DISABLE_OPTION_CHECKING([false]), or alternatively and more intuitively than two negatives IMHO; something like AC_OPTION_CHECKING(whichever). A quick grep for OPTION_CHECKING in the autoconf git repo didn't find me any new construct to achieve this. So, can I have a way to turn *on* option-checking by default from configure.ac and regardless of AC_CONFIG_SUBDIRS, please? Why this odd request? In RAPP, <http://savannah.nongnu.org/projects/rapp> (feel very welcome to have a look at its configure.ac), there's the hopefully self-explanatory: # The directory test/installtest isn't configured until after # installation, but to make autoreconf update this directory we # have to mention it here if false; then AC_CONFIG_SUBDIRS([test/installtest]) fi And no, test/installtest is not an imported package, just as you probably understood, a subdirectory with a hello-world-type test-program to check that installation works properly; that a program using the RAPP library can be built and run. This to present *one* hopefully valid reason for turning on option-checking despite AC_CONFIG_SUBDIRS. If the above construct is obsolete (I don't remember where I've seen it, but I guess either autoconf or automake docs) or there's just a better way, then I'm all ears (or eyes). Either way it seems odd if there's no way to actually make option-checking on by default, still overridable by the configure option --enable-option-checking of course. brgds, H-P _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
