Golang Compile For Windows On Mac

William Kennedy October 2, 2013 • • • Introduction In my post about building and running programs in, I needed to switched over to my Ubuntu VM to build linux versions of my test programs locally. I love the ability to have Ubuntu available to me for building and testing my code. However, if I can stay on the Mac side it is better. I have wanted to learn how to cross compile my Go programs for the two platforms I use, darwin/amd64 and linux/amd64. This way I could create final builds of my programs and publish everything from my Mac OS. After a couple of hours I am finally able to do this.

If you don’t have the need to cross compile your code then I recommend you stick with the traditional distribution packages and installs for Go. If this is something you need, then it all starts with downloading the current release of the Go source code. Installing Git The Go source code is stored in a DVCS called Github and is located on.

The problem with this is that if I built it on my Mac, the operating system would be for Darwin and the architecture would be for AMD64.

The first thing you need to do is install Git if you don’t already have it. Go to the download page on the Git website.

Cloning into ‘go’ remote: Sending approximately 57.30 MiB remote: Counting objects: 6825, done remote: Finding sources: 100% ( 1345⁄ 1345) remote: Total 194730 (delta 160700), reused 194473 (delta 160700) Receiving objects: 100% ( 194730⁄ 194730), 55.07 MiB 2.92 MiB/s, done. Resolving deltas: 100% ( 161032⁄ 161032), done. Checking connectivity done. Once that is done you now have a folder called go inside of the $HOME directory with the source code under src. Now change your directory to the go folder and checkout the latest version. Note: checking out ‘go1.4.1’.

You are in ‘detached HEAD’ state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b new_branch_name HEAD is now at 886b02d [release-branch.go1.4] go1.4.1 Building Go For Each Target Now you need to build the Go code for the targets you need. For now just build darwin/amd64 and linux/amd64.

First build the Go code for the darwin/amd64 target which is for the host machine. Crypto/x509 root_darwin.go:9:43: error: CoreFoundation/CoreFoundation.h: No such file or directory root_darwin.go:10:31: error: Security/Security.h: No such file or directory mime/multipart net/mail This means you don’t have the Command Line Tools for Xcode installed on your machine. To install the command line tools on 10.9 follow these instructions: Click the Install button for the Command Line Tools. Once that is done try building the Go code again.

Once the build is successful, open the Go folder. You should see everything you need for building Go programs on the Mac 64 bit environment. Export GOARCH='amd64' export GOOS='linux' go build file simple Simple: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped You need to change either one or both of the OS/ARCH environment variables to point to the target platform and architecture. Then you can build the code. After the build you can see the file command is reporting the program is a linux executable. As a reference, here are the different platforms and architectures you can build for cross compilation.

Go get -u golang.org/x/tools/cmd/godoc go get -u golang.org/x/tools/cmd/vet go get -u golang.org/x/tools/cmd/goimports go get -u golang.org/x/tools/cmd/gorename go get -u golang.org/x/tools/cmd/oracle go get -u golang.org/x/tools/cmd/gotype go get -u github.com/golang/lint/golint You may want to remove everything from the bin folder as well and go get them to re-build and install. Conclusion This is the documentation for building Go from the source: This is a document written by Dave Cheney about cross compilation. He has build a script that you can download. It makes all of this real simple to perform: Mitchell Hashimoto built this great tool called. This tool makes it real easy to build your program for all the different targets without the need to manually change the GOARCH and GOOS environment variables. Go Training We have taught Go to thousands of developers all around the world since 2014. There is no other company that has been doing it longer and our material has proven to help jump start developers 6 to 12 months ahead of their knowledge of Go.
