You cannot (naively) use the cmd.exe to run the fluidsynth binary that you've built in the MSYS MINGW64 shell. The MSYS shell probably sets up all kinds of environment variables, that make sure all .dll files are found during compile- and runtime. Most importantly the $PATH variable. That's why you should stick to the MSYS shell when attempting to run fluidsynth.
If you need to start fluidsynth from cmd.exe you should port the msys $PATH to win32 %PATH%, possibly also $LD_LIBRARY_PATH to %PATH%. Tom _______________________________________________ fluid-dev mailing list fluid-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/fluid-dev
