无法从OSX交叉编译到Linux

Question

When I try to cross compile my golang project from OSX to Linux, then I get following error message:

# runtime/cgo ld: unknown option: --build-id=none clang: error: linker command failed

and the compilation aborts.

This is how I try to build my application:

CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build

I also tried using gox:

 gox -os="linux"

but it still did not work.

Everything works as expected if I do not use the GOOS=linux tag and I am able to build/run my project for/on my OSX machine successfully.

You need to install a proper toolchain to do that.

In order to build binaries for architectures different that your build host, you need far more than just a cross-compiler - you need a full-blown toolchain, which can be a real pain to create, as you probably discovered.

A couple of approaches:

Use a proper Linux distribution in a virtual machine, such as VirtualBox. If you only want to build binaries for Linux/i386 on an MacOSX/x86_64 host, this is - in my opinion - the easiest, safest and most clean solution. It is not a cross-compiler, of course, but it works and it has the added advantage that you can actually test your executables.

Use a script such crosstool-NG (a descendant of the original crosstool) to automatically build the toolchain - definitely easier than building it on your own, although you may have to compromise for slightly older compiler versions.
