Hi, I want to use http://www.squeaksource.com/Z3950 Following install instructions, I've dowloaded yaz sources (I've tried 4.1.2 and 3.0.52) as it seems there's no binary for OSX, ./configure && make && make install. Then using latest Seaside One Click image I've copied /usr/local/lib/*yaz* in Seaside.app/Contents/MacOS $ ls ~/Downloads/Seaside.app/Contents/MacOS/ Squeak VM Opt libyaz.a libyaz.la libyaz_icu.a libyaz_icu.la libyaz_server.a libyaz_server.la libyaz.3.dylib libyaz.dylib libyaz_icu.3.dylib libyaz_icu.dylib libyaz_server.3.dylib libyaz_server.dylib But then I have a External Module Not Found on YAZPQFFFILibrary>>createParser " YAZPQDFFILibrary default createParser " <cdecl: YAZPQFParser 'yaz_pqf_create' (void) module: 'yaz3'> ^ self externalCallFailed Any hint ?
