From b235b50129b6195e502a5b25841a13d725a4766b Mon Sep 17 00:00:00 2001 From: Antonio Ospite Date: Fri, 9 Dec 2016 14:02:29 +0100 Subject: [PATCH] configure.ac: fix the check for xmlto availability The same $xmlto variable is used both in AC_ARG_ENABLE and AC_CHECK_PROG, but the latter is not setting a value to it when the program is not found. These two facts result in the "yes" value from the AC_ARG_ENABLE macro to be still kept in the variable when the program is not found by AC_CHECK_PROG, causing USE_XMLTO to be always set, finally resulting in a build failure in case the xmlto program is not actually in the PATH. As possible fix could have been to set "no" as a value in AC_CHECK_PROG when program is not found. However using two separate variables is more explicit, so fix the issue this way.
