Asterisk 1.2.1 on gentoo. Trying to use chan_capi-cm 0.6.1 results in: WARNING[11724] loader.c: /usr/lib/asterisk/modules/chan_capi.so: undefined symbol: use_ast_mutex_init_instead_of_pthread_mutex_init WARNING[11724] loader.c: Loading module chan_capi.so failed! Sounds like some version incompatibility - any ideas? Julf
