[Ambulant-users] build problem (net/ffmpeg_common.cpp:111: error: ‘CODEC_ID_MPEG4AAC’ was not declared in this scope)

Wed Apr 29 14:31:17 CEST 2009

I managed to compile libambulant! The trick was to remove the explcit  
references to -lavcodec -lavutil -lavformat -lavdevice from  lib*- 
uninstalled.pc and just keep -L${libdir}. I am not sure why this is a  
problem as they are supposed to reference the same libraries right?  
Anyway the next problem is :

gtk_logger.h:41:38: error: ambulant/lib/byte_buffer.h: No such file or  
directory.

ambulant/lib/byte_buffer.h seems indeed absent in CVS, is this correct?

Finally, I am happy to hear compiling ambulant will be easier in the  
future, it is indeed a bit of a hassle at the moment. Do you have a  
target date in mind? Perhaps  a daily build could be an option until  
then or is this too hard to setup? Anyway thanks a lot for ambulant!
