I'm getting the same issue. Did you find a way to fix it?

HowardDunn commented 2 years ago

Seems like cross compiling for arm64 from an amd64 pc causes this issue.

hktalent commented 2 years ago

Cross platform cross compilation is a beautiful lie. Let's give it up

rcolpaert commented 1 year ago

Ran into this issue on WSL2 when compiling the go code. The solution was to install gcc which wasn't installed yet and the code is just silently NOT being compiled. After installing gcc everything compiled fine.
