Please, give me a pointer to a basic implementation of that descriptor 
thing, somebody, please end my misery.

     Hello LADs

     I'm trying to make a GUI for a LV2 synth based on so-404. In fact,
     I'm trying to learn C / C++.

     I got everything to build OK, but I'm stuck on a hard to read
     execution error ; when I load the plugin in jalv, it loads it OK,
     but fails to load the UI and says :

     suil error: Unable to open UI library
     /usr/local/lib/lv2/kis.lv2/kis_gui.so
     (/usr/local/lib/lv2/kis.lv2/kis_gui.so: undefined symbol:
     _Z17instantiateSO_404PK15_LV2_DescriptordPKcPKPK12_LV2_Feature)

 % echo _Z17instantiateSO_404PK15_LV2_DescriptordPKcPKPK12_LV2_Feature 
 | c++filt
 instantiateSO_404(_LV2_Descriptor const*, double, char const*, 
 _LV2_Feature const* const*)
 %

 your plugin is missing a symbol (instantiateSO_404(...)), apparently.
