Re: [LAD] suil error: Unable to open UI library

In Harry's example <https://github.com/harryhaaren/lv2/tree/master/plugins/eg-sinsynth.lv2>, the methods that (AFAIU) LV2 expects : * instantiate() * connect_port() * activate() * run() * deactivate() * cleanup() * extension_data() Are declared explicitely, using static. Like this : static LV2_Handle instantiate(const LV2_Descriptor* descriptor, double rate, const char* bundle_path, const LV2_Feature* const* features) { SinSynth* self = (SinSynth*)malloc(sizeof(SinSynth)); // store the sample rate in "self" so we can retrieve it in run() self->sample_rate = rate; // initialize the phase so we start at the beginning of the wave self->phase = 0.f; return self; } void connect_port(LV2_Handle instance, uint32_t port, void* data) { SinSynth* self=(SinSynth*)instance; switch (port) { case AMP_FREQ: self->freq = (float*)data; break; case AMP_MIDI: self->MidiIn = data; break; case AMP_OUTPUT: self->output = (float*)data; break; } } static void activate(LV2_Handle instance) { } (...) Whereas in so-404, they are somehow "surcharged", like this : void runSO_404( LV2_Handle arg, uint32_t nframes ); LV2_Handle instantiateSO_404(const LV2_Descriptor *descriptor,double s_rate, const char *path,const LV2_Feature * const* features); void cleanupSO_404(LV2_Handle instance); void connectPortSO_404(LV2_Handle instance, uint32_t port, void *data_location); static LV2_Descriptor kis_Descriptor= { .URI="https://bitbucket.org/xaccrocheur/kis", .instantiate=instantiateSO_404, .connect_port=connectPortSO_404, .activate=NULL, .run=runSO_404, .deactivate=NULL, .cleanup=cleanupSO_404, .extension_data=NULL, }; So apparently instead of being declared thusly: LV2_Handle instantiateSO_404(const LV2_Descriptor* descriptor, double s_rate, const char *path, const LV2_Feature * const* features) {...} Either my instantiate method return value should be static, or my "mandatory" methods should be declared explicitely. I tried to adapt them, but failed so far. Please excuse my sub-newbie mistakes. --Phil
