Currently race cross compilation fails:

$ uname -a
Darwin .... 11.4.2 Darwin Kernel Version 11.4.2: Fri Sep  6 15:20:13 PDT 2013;
root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64

$ GOOS=linux go build

$ GOOS=linux go build -race
# github.com/highwire/hwcrawl/cmd/hwcrawl
runtime.raceinit: undefined: runtime/race.Initialize
dl_iterate_phdr(0): not defined
pthread_attr_setstacksize(0): not defined


It depends on cgo cross compilation:
https://golang.org/issue/4714

When that is fixed, we need to test that race cross builds work as well.

The cgo cross compilation is fixed. This issue need to be test. But I don't have native cross compiling compiler. Can somebody test it using CC_FOR_TARGET?

I have no trouble building binaries for darwin/amd64 with race detector on
linux/amd64 using pkg/darwin_amd64_race/* from official darwin/amd64
binary distribution. If the program itself doesn't use cgo, then cross compiling
with race detector doesn't even need a working cross compiler.

This still happens.
I'm trying to cross-compile with Go 1.5beta3 for Linux on a Mac with the race detector, and get the following error:

go version go1.5beta3 darwin/amd64
$ export GOOS=linux
$ export GOARCH=amd64

@gavrie That's a different problem. Please open a different issue. Thanks.

In the new issue, please add the output of "go build -x". I'm surprised that errors are coming from tool/darwin_amd64/link. That suggests that it hasn't even gotten to the GNU/Linux part of the build. It may be an error selecting the linker, or it may be an error in rebuilding the tools.

Do you by any chance have GOROOT set in the environment? If you do, try removing it.

Done, see #12122. I have not set GOROOT.
