Make it Buildable in linux

[kasivs]

IT fails to build in linux. Can it be made buildable in linux as our jenkins environment is a linux environment? Although we understand its runnable only in windows. But it should be buildable in linux. Because the build environment cannot be always windows.

[tlimoncelli]

You can cross-compile (compile on Linux, generate a Windows binary) using:

GOOS=windows go build

[dantran]

the error we found is at Go get, which does not make sense to me

[tlimoncelli]

I'm not sure of the exact problem, but I think the env variable GOOS isn't getting set to "windows" (without the quotes). Can you double-check?

[dantran]

manage to get GOOS into command line, fail with diff error

not sure why Go try to create a dir under my Go installation

[tlimoncelli]

Progress!

I'm not sure why it would try to write to that directory either.

Some things I noticed that may or may not be relevant:

• github.com/go-ole/go-ole isn't vendored.
• We use go 1.8.3, you are on 1.8.1.

The go toolchain has to build the std library for the platform you are targeting. It writes those package binaries to $GOROOT/pkg.

You can do this ahead of time with env GOOS=windows GOARCH=amd64 go install -v std once on the build agent.

[dantran]

@kavis, i can scale it down to a pom file

[dantran]

@captncraig it works

Thanks to all helping out
