Hi Hernan, finally I switch back to Linux to make it work, OSX gives me headaches.
So on linux the yaz module is found. I get the "Unable to find function address" but I found that writing: <cdecl: ZOOMOptions 'ZOOM_options_create' (void) module: 'yaz'> instead of <cdecl: ZOOMOptions '_zoom_options_cre...@0' (void) module: 'yaz3'> works. If I understand, function names are not mangled when compiling with gcc on Linux. Trying to run tests I've also had a "could not coerce arguments" in Z3950FFILibrary>>createConnectionTo:port because Z3950TestCase>>portNumber answers a String and <cdecl: ZOOMConnection 'ZOOM_connection_new' (char* short) module: 'yaz'> so it's waiting for a short. I've replaced portNumber to answer a SmallInteger. And now the image crashes on connectionIsIdle call: write(1, "\ncreateConnectionTo:port:", 25) = 25 write(1, "\nconnectionIsIdle:", 18) = 18 rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0 write(1, "\n", 1) = 1 tgkill(25830, 25830, SIGABRT) = 0 --- SIGABRT (Aborted) @ 0 (0) --- Any idea ?
