Congratulations, you're off and running with the autotools! A couple notes here: 1. I definitely did not get that patch to a working state. I only was just trying to get it going in the right direction. 2. Bryan has sent a couple patches to the hotplug list to decouple things a bit. One of them has to do with getting a capability include out of a udev file. You probably want to have a look at those to not duplicate work. 3. Here it seems that the capability system is being included unconditionally. save_LIBS="$LIBS" LIBS= AC_SEARCH_LIBS([cap_init], [cap], [], [AC_MSG_ERROR([*** POSIX caps library not found])]) AC_CHECK_HEADERS([sys/capability.h], [], [AC_MSG_ERROR([*** POSIX caps headers not found])]) CAP_LIBS="$LIBS" LIBS="$save_LIBS" AC_SUBST(CAP_LIBS) The 5th argument of AC_SEARCH_LIBS and 4th argument of AC_CHECK_HEADERS are "action-not-found". I.e., what to do if you didn't find a libcap library providing cap_init or the sys/capability.h header. You could wrap those AC_MSG_ERRORs in $enable_udev_only, but I think you could probably wrap this whole section in an if test $enable_udev_only = no block. You will need Bryan's patches to untangle capabilities from the shared sources, though. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
