GoReleaser cross compilation fails

Question

I'm trying to release my project in both linux and windwos machines without success.

I have tried to explicitly define the -CC to few options but non of them worked in both machines.

Pre installed packages:

sudo apt-get install build-essential sudo apt-get install gcc-multilib g++-multilib sudo apt-get install gcc-mingw-w64

In the project i'm using c code which uses these flags in order to selective compilation

//#cgo windows CFLAGS: "-IC:/Program Files/OpenSSL-Win64/include"
//#cgo windows LDFLAGS: "-LC:/Program Files/OpenSSL-Win64/lib" -llibcrypto
//#cgo linux LDFLAGS: -lssl -lcrypto
//#cgo CFLAGS: -Wno-deprecated-declarations

running GoRelaser locally on windows machine will result this error.

running GoReleaser locally on ubuntu machine will result

gcc: error: unrecognized command line option ‘-mthreads’; did you mean ‘-pthread’?

By default GoReleaser will attempt to make builds for 386, amd64 and arm64. But your windows machine is likey an amd64/x86_64 machine. Normally this is no issue with Go, but since you are using CGO your C toolchain has to support compilation for arm64, which it doesn't.

You should be able to limit the CPU architectures it attempts to build by adding goarch to your config file:

...
builds:
  goarch:
    - amd64
...

Cross compiling cgo projects is notoriously difficult and a known limitation of GoReleaser. I recommend taking a look at the cgo cookbook if you have not already done so.

As for the error you are getting on ubuntu, it looks like you C toolchain doesn't have the right dependencies/capabilities to cross compile to windows.

I have not done any CGO cross compilation myself(attempt to avoid it at all costs) so I can't vouch for this tool, but from what I am reading online xgo might be able to help you out.
