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

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