Yes you need mlt build because mlt++ calls mlt-config, but this problem is an obvious "Chicken or the egg issue" ... and the answer is "egg". The build for the subdir "test" in mlt++ needs libmlt++ already installed on the system. Think about it, your are building mlt++, that lib isn't on your system until you finish the package and install. This looks like one of those: (1) "Let's add the 'test' dir to the source so people will have it as a reference..." deals and then in some automagic/autoconf/whatever run later, the Makefile got generated saying: (2) "Hey, I found a subdir called 'test', let's add a directive to build 'test'" and since they were building it on a system where mlt++ was already installed, (3)the automagic files found the libmlt++ lib and included it in the library flags to build 'test'. This looks like exactly what happened to me, but I need someone to confirm this because "I don't know...." :) Give this a try on mlt (i686 only): ./configure \ --prefix=${TDEDIR} \ --enable-gpl \ --disable-sox \ --disable-qimage -- David C.
