#631 Build using separate object directory fails

[Olaf Seibert]

(at least I think that is what causes it).

With the gnu autotools, you can keep your source tree clean by creating some fresh directory, cd-ing into it, and calling ../some/where/configure. The resulting collection of Makefiles will build the sources located at ../some/where without messing up the source directories. This worked well with VICE before (apart from one small detail I papered over).

This is very handy (pretty much required) if you try keeping builds with various configure options, such as builds for xaw, gnome, gnome-threads, and sdl.

In this case, I have such a build, which called

$ ../vice/configure --enable-arch=no --without-oss --enable-fullscreen --enable-memmap --enable-ethernet --enable-static-ffmpeg

(and some environment variables to make configure find stuff it doesn't find by itself)
(--enable-shared-mpeg ends in the same way)

The configure phase appears to work well, including the build of ffmpeg.

The resulting build fails with

No rule to make target '../../../../vice/src/lib/libffmpeg/Makefile.am',
needed by '../../../../vice/src/lib/libffmpeg/Makefile.in'.

like this:

For the moment this is blocking bug #624 [bugs:#624]

This has been fixed some time ago. I use ouf-of-tree building a lot when testing bugfixes or new code using Xaw, Gtk2/Gtk3 and SDL1/SDl2 on both Linux and BSD, both with and without ffmpeg.
