It must be GOOS=linux GOARCH=amd64 go install -x with the -x after install. I think that $CC does nothing for go. When I use it it still uses go's 6c. Example:

Also, I've found this https://code.google.com/p/go/issues/detail?id=4714 . Seems like it is on the subject. CGO_ENABLED is forcefully set to 0 when corss compiling for some reason.

Now I'm wondering if it is not possible to do cross platform compile as it contains c program, so it is not in pure go?

Well It seems it is exactly that. For example when building for my native machine with CGO_ENABLED=0 I did get the same message:

$ CGO_ENABLED=0 go install -x

On the other hand when I try to cross compile with CGO_ENABLED=1 I got the hardcoded message

$ CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go install -x
WORK=/tmp/go-build587075426
mkdir -p $WORK/runtime/cgo/_obj/
mkdir -p $WORK/runtime/
go build runtime/cgo: cannot use cgo when compiling for a different operating system

You can find it in the go build tool source:

[~/go/src]
iron4o$ search 'cannot use cgo when compiling for a different operating system'
cmd/go/build.go-    if goos != toolGOOS {
cmd/go/build.go:        return nil, nil, errors.New("cannot use cgo when compiling for a different operating system")
cmd/go/build.go-    }

I am thinking of removing this and rebuilding my go tools :D But that will be left for later.

@ironsmile WOW, what a hack you are going to do!
Now I think it's reasonable that by the nature of C, it might be not that easy to compile a Windows executable from a Mac, or Linux.

I'm having a similar issues trying to cross-compile a windows executable from a 32-bit debian machine:

As the fix under https://code.google.com/p/go/issues/detail?id=4714 should be now in the 1.3 release, is there any chance to get cross compilation working?

With Go 1.3 I'm getting ATM:

I'm running OS X 10.10.

Is there a way to tell gcc to not define _HAVE_MINGW_H or _HAVE__MINGW_H?

#if defined(_HAVE_MINGW_H)
# include "mingw.h"
#elif defined(_HAVE__MINGW_H)

I don't understand, why GOOS=linux triggers the include of mingw on my Mac?

Hey guys!

I have same problem with gcc and gocx. I don't have impressive experience with compiled languages and i hope that you can tell me what wrongs.

I've setup this package by "go get" and just include it to my source.

When i try compile it by "goxc" i get "../github.com/mattn/go-sqlite3/sqlite3.c:94 8c: No such file or directory: mingw.h".

@mattn you mentioned cross compiler, what is it? How i can install it and using? Why i've get this error message for all platforms exclude my host platform?

Thank you.

@antonydevanchi

And if i run "GOOS=linux GOARCH=amd64 go build" complier works properly. I've got binary file.
But if i change GOARCH to 386 i've got the same problem related with mingw.h.

@marcboeker I was struggling with cross-compiling for raspberry pi as well. I ended up biting the bullet and installing Go on the RPi using http:https://dave.cheney.net/unofficial-arm-tarballs and compiling natively. Make sure you set VRAM to around 16 so compilation doesn't take forever!

@marcboeker

@imheresamir Thanks for the hint. Yeah, that's exactly what I'm doing at the moment and it is so slow :) But I'm going to try the VRAM option, hopefully this speeds things up. Thanks!

I have the same problem on osx, attempting to build linux/amd64 version for my program.

ld: unknown option: --build-id=none
clang: error: linker command failed with exit code 1 (use -v to see invocation)

try with export CC=gcc.

are you doing cross-compiling? when you need to use cross-compiler not host-compiler.

Ran into similar issue cross-compiling a linux binary on osx. Near as I can tell in my mini investigation, cross-compiling would work except that osx's implementation of the linker tool (ld) doesn't understand the --build-id=none flag, which is where it chokes. Both gcc and clang attempt to pass this flag along to ld regardless of what you do with the CC, GCO_ENABLED, etc environment variables, so it's simply not gonna work.

I have a simple work around using docker which will hopefully help others who don't want to go through the trouble of recompiling a linux version of ld for osx:

Note: Naturally a docker workaround will require that you have docker installed :)

@mattn If you think it's reasonable feel free to add it to your readme where it will be more visible. I can make a PR as well if you like.

docker run --rm -v $GOPATH:/go -w /go/src/path/to/app golang:latest go build -v

This will put your executable in the expected place, in this case, $GOPATH/src/path/to/app.

You just need to update that /go/src/path/to/app part to be your actual directory containing your app, for example, /go/src/path/github.com/username/awesomeSqliteApp

If you want this working in a script like I have (for example I use a python fabric script to build and deploy automatically), you can do the following to prep docker on osx, since otherwise it requires the "Docker Quickstart Terminal":

eval $(docker-machine env default)
docker run --rm -v $GOPATH:/go -w /go/src/path/to/app golang:latest go build -v

In theory this should work on any platform that can run docker, though I've only tried on osx.

@jeffbmartinez Thanks. Using docker is one of the way to do cross-compiling. So it's useful. If possible, could you please send me pull-request to update README.md?

Leaving this comment in the hopes it helps someone else in 2016.

Cross compiling Linux (Debian Jessie amd64) -> Windows (amd64) and OSX (amd64) worked for me with the following:

To Windows:
apt-get install gcc_mingw64
env CGO_ENABLED=1 GOOS=windows GOARCH=amd64 CC=x86_64-w64-mingw32-gcc go build $appname

To OSX:
Follow instructions at https://github.com/tpoechtrager/osxcross to build apple cross compiler
env CGO_ENABLED=1 GOOS=darwin GOARCH=amd64 CC=o64-clang go build $appname

@cprevallet Thank you, (ubuntu)work for windows.

apt-get install gcc-mingw-w64

for documentation purposes:
in order to cross compile 32bit ubuntu on a 64bit ubuntu system libc6-dev-i386 is required.
Setting CC="gcc -m32" works.

@jeffbmartinez use docker run --rm with sqlite3 , i cannot build , sth is wrong , go build -v is nothing with hold..

Thanks @jeffbmartinez, it got me on the right track to get cross compilation working for Raspberry Pi 3. In case it's useful for anyone else, here's the Dockerfile I'm using for OSX:

FROM dockcross/linux-armv7:latest

# Largely copied from the official Golang image Dockerfile

RUN set -eux; \
  wget -O go.tgz "https://golang.org/dl/go1.9.1.linux-amd64.tar.gz"; \
  tar -C /usr/local -xzf go.tgz; \
  rm go.tgz; \
  export PATH="/usr/local/go/bin:$PATH"; \
	go version

ENV GOPATH /go
ENV PATH $GOPATH/bin:/usr/local/go/bin:$PATH

RUN mkdir -p "$GOPATH/src" "$GOPATH/bin" && chmod -R 777 "$GOPATH"
WORKDIR $GOPATH

And the command to build a package from the package directory:

PWD=$(pwd)
PROJECT="/go${PWD/"$GOPATH"/}"

docker run --rm -v $GOPATH:/go -w $PROJECT \
  -e "CGO_ENABLED=1" -e "GOARCH=arm" \
  go-arm-linux:latest go build .

After some searching, I found a way to cross compilation on OSX:

  1. Install cross-compiler toolchains
brew install FiloSottile/musl-cross/musl-cross
brew install mingw-w64
  1. Build with -ldflags "-linkmode external -extldflags -static"

Ex:

GOOS=linux GOARCH=amd64 CC="/usr/local/bin/x86_64-linux-musl-gcc" CGO_ENABLED=1 go build -ldflags "-linkmode external -extldflags -static" -o [OUTPUT_BINARY]
