btw: the build error is here: https://github.com/seaweedfs/seaweedfs/actions/runs/3262244509/jobs/5359129932

You are using host C compiler. It MUST be cross C compiler for Windows.

[chrislusf]

Correct. Need to build for windows with github actions.

[leeweisberger]

This is also breaking our release train for windows with github actions. Same error as originally posted.

Any solution?

Facing the same issue on Linux, compiling for Windows, CGO is not enabled.

[abemedia]

Had the same issue building on Windows with CGO.
Reverting to v0.0.7 fixed the issue so just add the following to your go.mod as a temporary workaround:

replace github.com/mattn/go-ieproxy => github.com/mattn/go-ieproxy v0.0.7

Weirdly this only seemed to affect 386 arch (using CC=i686-w64-mingw32-gcc and CXX=i686-w64-mingw32-g++).
Might wanna add a test for that in GitHub actions...
