I''ve made some progress on getting Scintilla to work on OS X. I got a static build of wxscintilla as libwxscintilla.a. To do this, turns out all I needed to do was make release But I had to go a tortuous route to find this out. Anyway, this gives me a library against which I can build the wxscintilla sample. It also builds without error when added to wxruby (following the model of rakemswin). I get a Scintilla.o, and a libwxscintilla.a is linked into wxruby2.bundle. All seems good, but when I run bigdemo.rb, I don''t get Scintilla - it seems Scintilla isn''t a constant. Any tips as to what might be happening? I wondered if I needed to build a unicode wxscintilla? thanks alex
