crosscompile on darwin for linux: undefined symbols

[iharsuvorau]

I would be very happy if someone can post a recipe how to build this pkg on OS X for linux?

Running this

GOOS=linux GOARCH=amd64 CGO_ENABLED=1 go build -v .

on my program which uses the package fails with the message:

/usr/local/Cellar/go/1.10.2/libexec/pkg/tool/darwin_amd64/link: running clang failed: exit status 1
ld: warning: ignoring file /var/folders/9k/vjqfzdjs31ng3nljg71nmnxm0000gn/T/go-link-939718562/go.o, file was built for unsupported file format ( 0x7F 0x45 0x4C 0x46 0x02 0x01 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 ) which is not the architecture being linked (x86_64): /var/folders/9k/vjqfzdjs31ng3nljg71nmnxm0000gn/T/go-link-939718562/go.o

There is a similar question on stackoverflow but it has no answer too.

Hey @iharsuvorau - apologies for the super long delay. MacOS build instructions are now in the readme and you shouldn't have any problems building there. We've recently integrated a bunch of new functionality and bug fixes and macOS is a supported platform - hope you're willing to try again!
