[fluid-dev] FluidSynth 2.0 beta issue

[Graham Goode]

Hi,

I'm not a programmer, but I know enough to compile and troubleshoot a little.

I build the windows versions of Fluidsynth for the jOrgan project,
using MinGW for the default Dsound version, and then Visual Studio for
the WASAPI/WDMKS/ASIO backends.

I started doing this back in 2014 with Fluidsynth 1.1.6, and have
successfully compiled and tested releases up to Fluidsynth 1.1.11.

I gave the Fluidsynth 2.0.0 beta 2 code a try, building with MinGW.
That compiled correctly. I then swapping out the headers in the
fluidsynthJNI folders and using my MinGW build of libfluidsynth
attempted a build of the wrapper, which failed with the following
messages:

Any ideas?
