Regarding the build log, I dont see why you think it uses c++ as linker. It correctly calls gcc.exe, line 15. Still strange that it doesnt find libintl although it should be in %path%. Have no further ideas so far.

Anyway, yes, that would be the correct useage.
Even if you manage it to get "appropriate header files" for all audio drivers, against which libraries would you link in order to create that single dll, given the fact that alsa, oss and coreaudio are not available on windows?

I am already compiling similar support for foreign midi inputs into my project.Obviously it wont use the interfaces when the program is run on windows but it can use them when it isrun on other operating systems. Read the fluidsynth user documentation and read up about, or even trymy eplayOrgan which uses four instances of fluidsynth. See
https://midimusic.github.io/and can redirect each output to a different sound driver.

Think about it: How would you compile fluidsynth with ALSA or OSS support on windows? The ABI and calling conventions between different OSs vary. I dont see how this could work.

I tell it -G "MinGW Makefiles" (there is no other useful option) so it does not know whetherit is working with C or c++ so it goes for c++ which can (in theory) do both.
> > I will have to investigate portaudio. I am currently in learning mode regarding audio interfaces but it would seemto me that fluidsynth DOES have the capability to contain ALL of the common audio interfaces (for Mac, Linux,and Windows) and the interface it uses depends upon which one it finds first when it is run. This is documentedin fluidsynth's user documentation.

I suspect it would be best for me to write my own makefile and I can then put what I want into it. This willavoid me trying to understand the mess (which usually does work) that cmake creates.
