Surely many people > have already solved this problem by now. A little further searching leads me to question that statement. It seems that SCons prefers not to use libtool, because it does not work with Windows tools. http://osdir.com/ml/programming.tools.scons.user/2003-10/msg00107.html The suggestion about appending version numbers to the .so file name is probably worth considering. I'll give it some more thought. I do think version numbers are going to be important for libffado, given the need to coexist in the field with different versions of JACK and other users of the library. -- joq _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
