FAIL pact2example [build failed]

But what I noticed is that in VSCode all modules where not found which contain cgo-code. So I guess that might have something to do with cgo?!?

Why is CGO_ENABLED=0 ? That will definitely be an issue.

Here is an example working project: https://github.com/pactflow/terraform-provider-pact/

Ideally could you please provide a full project/repository that can be cloned that demonstrates the issue? Closing until you can demonstrate the problem.

You are right. After I had some difficulties getting a reasonable gcc to run with Windows, which also recognizes the libpact_ffi.dll, I decided to switch to devcontainer. Unfortunately, my first attempts under alpine with musl also drove me almost to despair. Using a Debian image with full gcc, everything went smoothly with PACTv2. Thanks for the hint with CGO_ENABLE=1

There is some guidance on Alpine here, perhaps I could bring in a summary of that into this repo. TL;DR - it's not supported due to the use of musl and although it's possible to make it work, it's likely to be unstable.
