It seems that libcsound is not included in the regular csound release. Or at least that the installed libcsound.a is compiled with jpff_glue instead of csound.c, making it useless for programs using the API. What version should I tell people to get if they want to use my jcsound program that requires a libcsound installed? I think the same goes for wxcsound as well. regards Gerard -- electronic & acoustic musics-- http://www.xs4all.nl/~gml
