I'm pretty sure this will solve the xbmc problem as well but let me come back with a final confirmation later on.
Found also this link regarding the same error: http://ffmpeg.org/pipermail/ffmpeg-user/2012-December/012307.html. May I suggest one of the following changes regarding the gas-processor.pl: 1) Distribute a prepackaged version of gas-processor.pl that works, together with ffmpeg. 2) At the very least, update the docs (docs/platform.texi) regarding the gas-processor.p referense to "https://github.com/mansr/gas-preprocessor"; and also add some controls to "Configure" that verifies that the correct version of gas-processor.pl is used. Personally, I would prefer point nr 1. And finally, many Big Thanks to all who helped and assisted with this problem, especially to Carl that came up with a lot of different ideas and managed to find the right track (gas-processor.pl) and to Alexey that found a solution to the last error. /Regards, Lars.
