runtime/cgo: Cannot compile w. GOOS=freebsd on macOS #18189

msiebuhr · 2016-12-03T22:06:59Z

Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (`go version`)?

go version go1.8beta1 darwin/amd64

What operating system and processor architecture are you using (`go env`)?

GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/msiebuhr/Source/go"
GORACE=""
GOROOT="/usr/local/Cellar/go/1.8beta1/libexec"
GOTOOLDIR="/usr/local/Cellar/go/1.8beta1/libexec/pkg/tool/darwin_amd64"

CXX="clang++"
CGO_ENABLED="1"

CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"

What did you do?

On macOS (X), cross-compile a Go program to FreeBSD (I used https://github.com/msiebuhr/prometheus-mdns-sd, but it seems any will do):

GOOS=freebsd go build .

What did you expect to see?

A freebsd binary being built

(1.7.4 builds a working freebsd binary without any complaints.)

What did you see instead?

# runtime/cgo

You need to disable cgo by setting $CGO_ENABLED=0 for cross compilation unless you have a FreeBSD cross compile toolchain on macOS.

davecheney · 2016-12-03T23:59:21Z

This should happen by default, CGO_ENABLED should defualt to zero when the target GOOS/GOARCH does not match the host. Did this change recently?

I can confirm that CGO_ENABLED=0 GOOS=freebsd go build . works (built, copied to FreeBSD and executes)

davecheney · 2016-12-04T00:18:33Z

Can you please include the full output of invoking go build -x for your project.

I cannot reproduce this failure on my machine (running tip, which is pretty close to 1.8beta1).

Can you please run this command and paste the output

env GOOS=freebsd go list -f '{{ .ImportPath}} {{ .CgoFiles }}' $(env GOOS=freebsd go list -f '{{ join .Deps  "\n" }}' github.com/msiebuhr/prometheus-mdns-sd)

Something is forcing CGO_ENABLED=1 in your system. Can you try another system or another way of installing Go (not via homebrew in case that is the cause)

msiebuhr · 2016-12-04T09:08:36Z

Just tried on similar macOS machine, where it fails in the same way (and I get the same go list output). It should probably be noted that I make some effort of making the two machines have a roughly similar setup, so it could be an artefact of something I'm doing both places...

msiebuhr · 2016-12-04T09:19:48Z

Works with a checkout from tip!

The output from go list doesn't have any cgo-mentions, when done with tip.

minux · 2016-12-04T09:39:57Z

Yeah, Homebrew is known to build non-working Go in the past. It must have forced CGO_ENABLED=1 during build (the Go make.bash can detect the correct setting for it automatically.)

msiebuhr · 2016-12-04T12:34:14Z

@minux brew rm go && brew install go --devel --without-cgo does indeed produce a toolchain that can cross-compile!

(An aside: When CGO_ENABLED=0 when building the toolchain, is it merely changing the default for the compiler or is it built without CGO capabilities?)

davecheney · 2016-12-05T00:47:52Z

CGO_ENABLED=0

You don't need to set this value, it always defaults to the correct value. I think what is going on is brew are setting it, and that is messed you up. I think this bug should be assigned to the maintainer of the homebrew formular for Go.

msiebuhr · 2016-12-05T07:59:42Z

That was my thought as well - I just wanted to be sure of the details.

It produces builds that behave in non-standard ways (i.e. produces non-obvious errors when cross-compiling). See golang/go#18189 (comment) Closes #7556. Signed-off-by: ilovezfs <ilovezfs@icloud.com>

What version of Go are you using (go version)?
