i386 image faild about docker-go-mingw

[boy-hack]

Thank you, the new version solves my problem very well

It seems that this image can only be used under 32-bit. If I want to use 32-bit compilation under x64, what should I do?

@boy-hack that image can be used under 64-bit (I built it on 64-bit machine). This image is based on docker's official golang image for i386 architecture - https://hub.docker.com/r/i386/golang.

i386 instruction set is well supported by Intel chips and 32-bit binaries can be run on x86_64.

What king of mac are you using? (macOS version and model)
Can you try to run it?

docker run --rm -it --platform linux/386 i386/golang sh

I tried to run this on MacBook Pro mid 2015 with macOS Big Sur and unable to reproduce your issue:

@boy-hack I changed approach a bit. Now it's a single image as it was before but based on Debian Bullseye which provides Mingw toolchain for both amd64 and i386.

Use GOARCH=386 variable to build a binary for 32-bit. Also, please re-pull x1unix/go-mingw image.

docker run --rm -it -e GOARCH=386 -v /YourPackageSrc:/go/work \
    -w /go/work \
    x1unix/go-mingw go build .
