The first error unsupported compiler is bogus - it really checks OS, not compiler.
The rest are likely results of missing include statements.

Version: 1.2.0
FreeBSD 13.1

The first move/forward are either a missing #include <utility> or a C++11 flag that's not properly set up for this particular file.

The last error is my own patch, and execvpe has no equivalent in BSD land. I don't really have the spare time to support BSD at the moment but if you want to have a shot at these I'd gladly accept patches !

Note: all of these are problems in VSTGUI; our fork is at https://github.com/sfztools/vstgui if you want to submit tpatches there, or directly upstream even, although for other reasons we're not tracking the latest version right now.

Once unsupported compiler was solved with

-#elif defined(__linux__)
+#elif defined(__linux__) || defined(__FreeBSD__)

the other errors disappeared.

The execvpe problem was patched with #define execvpe(a, b, c) execvp(a, b).

If you could add an option to use an external vstgui this would be the best solution.

@yurivict could it be OK having the possibility to build the entire SDK for sfizz from a "src package"? I see you have https://cgit.freebsd.org/ports/tree/audio/vst3sdk/ in Ports, though I don't see a pkgconfig file, or do you need a specific option for VSTGUI only?
Because we have a SFIZZ_USE_SYSTEM_VST3SDK CMake option, but it works finding the package using pkgconfig, it is used at least by Archlinux.
If needed here for reference their vst3sdk.pc file in their PKGBUILD repository.

[redtide]

I forgot to tell you that maybe you could be interested in this VSTGUI PR to use as patch, hoping they'll consider to merge it someday.

Closing, please reopen if needed.
