I am working on a project where i have a C application that needs to call an sdk that is written in Go. We have created a wrapper DLL that we can invoke from our C application. However, the marshaling of non-primitives has me a bit stumped.

I’m newer to go and I’m trying to pass a pointer to some C code so that it can call a method with that pointer and I can access that pointer again. Here is a simple example of what I’m trying to do:

While cross-compiling a Go project for ARM on FreeBSD I came across a few errors that don’t make sense, for example unsupported option -mno-thumb or unused option -marm. I suspect that there is potentially a bug in the tool that compiles C code.

What’s the issue? I want to connect Go to NodeJS using napi-go. When I run go build -buildmode=c-shared -o “example.node” . this is the error I get: cgo: cannot parse $WORK/b046/_cgo_.o as ELF, Mach-O, PE or XCOFF Expected An “example.node” file should be created which can be required in the index.js file.
