It should be easy to deal with the undefined _CreateCsoundVST. Presumably, 
you have now built _CsoundVST.so or .dylib or whatever. You now need to add 
that library to your link line for csoundvst_main (and perhaps other 
libraries as well, see the Linux link line for ideas).

Mike

You mean in SConstruct?  Ah, well, that gives the right solutions to 
some of the previous problems.  I now have a CsoundVST!  And it fails to 
run like this:

csound5 ./CsoundVST
Starting CsoundVST...

But the build still goes on to fail with

and so on, with screenfuls of errors.  I'll look a this in the morning.

As it happens, I can't build the DLL for csound either.

I just happened to try that.

You have found a bug in SConstruct.
At line 621, replace this

if not ((commonEnvironment['useFLTK'] == '1' and fltkFound)):
     print 'CONFIGURATION DECISION: Not building with FLTK for graphs and widgets.'
else:
     print 'CONFIGURATION DECISION: Building with FLTK for graphs and widgets.'
     fltkEnvironment = csoundLibraryEnvironment.Copy()
     if (commonEnvironment['noFLTKThreads'] == '1'):
       fltkEnvironment.Append(CCFLAGS = ['-DNO_FLTK_THREADS'])
     libCsoundSources.append(fltkEnvironment.Object('InOut/FL_graph.cpp'))
     libCsoundSources.append(fltkEnvironment.Object('InOut/winFLTK.c'))

with
