I checked, and it seems that this is synfig's fault, because running that command by itself doesn't exit. So synfig is not writing to the pipe properly or something. > It looks like the change occurred at version 0.4.6. The latest version > is 0.4.9.pre1.

I didn't pick the options, that was the developers when synfig was an in-house proprietary app for Voria Studios. > Well, this was the source from the synfig website.

There should be at least gif, ppm, bmp and yuv420p, since these don't seem to need external libraries and should be always built. > Where do I enable support for different targets? Mostly, the libraries needed for each of them are detected when you run ./configure, there are several --with-xx options. Run ./configure --help to see what switches are available. There are exceptions for a couple that use external binaries instead of libraries, for those, you can enable them with a configure switch even if you don't have them installed. -- bye, pabs http://wiki.synfig.com/PaulWise
