x/sys/windows/registry: Compile on MacOSX?

[andy.g...@gmail.com]

Hey,

i am in the progress of writing a small helper tool that need to run on MacOSX, Linux and Windows.

On MacOSX and Linux i need to access some files.

On Windows i need to read a value from a registry.

For this i want to use the golang.org/x/sys/windows/registry package.

So i have something like

switch runtime.GOOS {

case "darwin":

...

case "linux":

...

case "windows":

...

}

in my code.

Everything works fine for darwin and linux.

But when i start to developing with golang.org/x/sys/windows/registry on MacOSX i am not able to compile / get the code by go get:

$ go get golang.org/x/sys/windows/registry

can't load package: package golang.org/x/sys/windows/registry: no buildable Go source files in /Users/agrunwald/Development/Go/src/golang.org/x/sys/windows/registry

I am developing this app on MacOSX.

Am i right that i only able to compile this app on a windows machine?

Or is there a trick i miss?

Thanks,

Andy

Okay. In the meantime i found one solution: Using Build Constraints.

See these in action here: https://github.com/trivago/gollum/blob/ab7348416bb3d29aebc15f588c5643667c6e83f4/signal_unix.go#L15

Documented here: https://golang.org/pkg/go/build/#hdr-Build_Constraints

Any other solution?

Nope, you need to use build constraints, and build for target platform. Just switching on GOOS doesn't help when the code for other platforms can't be compiled at all.
