Hi all, I am currently working on porting the midi i/o of JSynthLib to use the ALSA sequencer api rather than OSS. JSynthLib is a synthesiser librarian written in java. I am using JNI (java native interface) as the glue between c and java. The way this works is that a java tools creates a header file containing the functions you required to be implemented nativley, you then implement these functions, and finally compile them into a shared library that your java code loads. This is all working fine, except when i go to make calls to the sequencer api. ALSA gives me the following errors: ALSA lib dlmisc.c:100:(snd_dlsym_verify) unable to verify version for symbol snd_config_hook_load ALSA lib conf.c:2655:(snd_config_hooks_call) symbol snd_config_hook_load is not defined inside (null) ALSA lib conf.c:3066:(snd_config_update_r) hooks failed, removing configuration Open error: No such device or address I noticed that dlmisc.c has a printf on line 98 that is gives a bit of info, so uncommented it and got the following info: dlsym verify: -2, vname = '_snd_config_hook_load_dlsym_config_hook_001' Well, using nm to look at libasound.so reports that symbol as present. So I'm a bit confused. I'm using alsa-lib-0.9rc3 on redhat 7.3 with gcc 2.96. Any ideas? Thanks, Ian
