What did you do?

What did you expect to see?

node-gyp compiling the module correctly with a golib

What did you see instead?

On mac it works, when I use gcc, g++, or any other compiler it works on windows, but with msvc it gets an error

Thank you for opening an issue @rocketdv. Can you provide the exact command you are running to compile?

When building the go library, I run go build -buildmode=c-archive -o libgo.a main.go
That generates the archive and header files, then I have to edit the header file, because the complex types cause compiler errors with node-gyp. I am unsure of the exact command node-gyp uses but it is MSBuild, and when it runs it fails to compile, it is an issue with MSBuild, or golang on windows, because it builds fine and runs on MacOS

Unfortunately, MSVC is not supported. GCC and Clang are the only supported C toolchains.

Generally, a C compiler and linker are only needed if your project includes cgo or you're using a non-default build mode that requires external linking. Not sure which applies here, but in any case, MSVC won't work.
