When cross compiling, you should use go build, not go install. Once all the preparations have been done, it's just a matter of calling. Golang: How to cross compile on Linux for Windows. In most cases you just have to replace the apt-get package manager commands with the one's from your distro. How to cross compile To cross compile a Go program using Go 1.5 the process is as follows: set GOOS and GOARCH to be the values for the target operating system and architecture. MinGW is available on Linux and Windows. Both of them are written in C. I personally like Debian flavored Linux systems. amd64, i386, armel, armhf, arm64, mips, powerpc and ppc64el. MSYS2 provides read-to-go installers for Windows, but installing MSYS2 on Linux is a bit more work. Active 2 years ago. Using this container as the base image, I created containers to compile remoteAudio for windows/amd64 and windows/i386 directly from Linux. We use the variable GOOS for the target operating system, and GOARCH for the target architecture. We could all set them inline when calling the gocompiler, but for the sake of clarity we will set and discuss the variables one by one. Cross-compiling works by setting required environment variables that specify the target operating system and architecture. Being on a 64 bit Ubuntu 14.04 host, doing either a default build or specifying a 64 bit binary explicitly results in: And you can also verify the binary target architecture by having the ‘file’ command look at the header: For Linux, to check if the binary is statically or dynamically linked, use the ‘ldd’ and ‘readelf’ utilities. So in order to compile our (c)go program for windows/amd64 and extract the dlls, we just execute: In this article I've explained my approach on how to cross compile Go applications which depend on C libraries for different architectures & operating systems. By default xgo tries to cross compile to the lowest possible versions of every supported platform, in order to produce binaries that are portable among various versions of the same operating system. 3. linux go gcc cross-compiling. ... # GoLang cross-compile snippet for Go 1.6+ based loosely on Dave Chaney's cross-compile script: Dependencies will be automatically correctly resolved. 1. Assuming you have installed Go and have the proper environment variable setup, run the following commands on Ubuntu (or the equivalent on Windows): And then either copy the simple go file below, or download it directly from my github project. 0. Once for linking & compiling and once for the pre-build DLLs which we later extract conveniently with a script. The below output is for a statically linked binary. # install build dependencies (code generators), My thoughts on Amateur Radio & Software Development, build the (GCC based) cross compiler yourself. That's what this article has been written for. A nice feature of the Go language is the ability to build binaries for multiple platforms directly from a single source system. In case you don't use pkg-config and haven't specified LDFLAGS with a cgo directive in your source code, you can specify the locations of the libraries and header files with the -ldflags flag: While we could certainly install everything required for cross compiling on our host system, I personally prefer to keep my host system as clean as possible. Inspired by Dave’s script, goxc is a go application that not only cross compiles, but also can compress the different binaries and package them with the readme and license. Skip to content. The crosscompile.bash script has been removed to prevent accidents from people coming here from outdated links. arm64) differs from our host's architecture (amd64), we cannot simply install the needed libraries with apt-get. Go (golang) is a general purpose, higher-level, imperative programming language. You can find the Dockerfiles in the respective folders of the remoteAudio-xcompile repository. As an example, even from a development Windows 7 32-bit machine, you can build binaries for both 64 bit Linux and Windows 2012 Servers. Go Cross-Compile Script. As an example, even from a development Windows 7 32-bit machine, you can build binaries for both 64 bit Linux and Windows 2012 Servers. Before Go 1.5, you needed a compiler for the target architecture, but now that the entire tool chain is written in Go, building for multiple architectures is easy. Changed conventions: validation.go and placeholders.go moved to a new http/validation package.. Validation rule sets are now located in a request.go file in the same package as the controller.. As it turns out, some smart folks have solved this problem and created MSYS2 which is a software distro and building platform for Windows. For example, remoteAudio depends also on libopus and libportaudio. While one can achieve a lot in native Go, sometimes there is just no way around using C libraries. With GOOS and GOARCH we tell the go compiler the operating system and architecture of our target system. This is the system on which the compiler and the tools are run. And unlike other languages where additional external libraries need to be copied or downloaded on the target system, Go dependencies are generally statically linked [1,2,3,4] into a single binary which makes portability that much easier. However, we often depend on additional libraries. In order to compile the program for arm64 you just need to call from the source directory: With the -v flag we mount the current directory of our host ($PWD) into the container under the path /usr/src/myapp. These packages are distinguished by the : suffix. It includes the MinGW compiler for windows, and an OSX SDK. In the case of remoteAudio, I'm using for example the OPUS audio codec and Portaudio for handling cross-platform Audio APIs. Let’s start by creating a very simple Go application. As of Go 1.5 cross compilation can be performed with the official distribution from golang.org.For more information pleaes read this blog post.. Just in case you wonder, the pkg-config files are installed automatically with the corresponding package library. To my knowledge, Debian supports at least the following architectures: You could build the (GCC based) cross compiler yourself, run go build -v YOURPACKAGE By default xgo tries to cross compile to the lowest possible versions of every supported platform, in order to produce binaries that are portable among various versions of the same operating system. Motivation: Separating the requests in another package added unnecessary complexity to the directory structure and was not convenient to use.Package naming was far from ideal with the "request" suffix. One could re-implement those libraries in Go, but often it's just not feasible. There are two important terms which have to be defined: In my case, the Host System is Linux/amd64. For the case above, we can find the arm64 libraries in /usr/lib/aarch64-linux-gnu/ and the corresponding header files in /usr/include/aarch64-linux-gnu. Before we can cross compile our (c)go program, we have to set a few environment variables. Before we can cross compile our (c)go program, we have to set a few environment variables. To build an executable, the command would take this form: Putting the Cross compilation chains into Docker containers does not only keep our host system clean, it also documents build process and shows the needed dependencies. This is the one of the few cases where go build is preferable to go install.The reason for this is go install always caches compiled packages, .a files, into the pkg/ directory that matches the root of the source code.For example, if you are building $GOPATH/src/github.com/lib/pq, then the compiled package will be installed into $GOPATH/pkg/$GOOS_$GOARCH/github.com/lib/pq.a.This logic also holds true for the st… Over the years, Docker has become one of my indispensible tools. MSYS2 is built around the MinGW-w64 toolchain and comes with a ported version of Arch Linux’ package manager Pacman. 5. Before 1.5, cross compilation was an arduous process, requiring massive scripts to build separate go compilers for each supported platform. We use the variable GOOS for the target operating system, and GOARCH for the target architecture. Debian based distributions come fortunately with Multiarch support. GitHub Gist: instantly share code, notes, and snippets. With GOOS and GOARCH we tell the go compiler the operating system and architecture of our target system. As of Go 1.5 cross compilation can be performed with the official distribution from golang.org. GitHub Gist: instantly share code, notes, and snippets. So installing the opus and portaudio libraries (and header files) for arm64 looks like this: The Debian package manager will store the installed files on our host system in folders named after the respective architecture. Let’s use a simple go file as an example. However it should be also valid for all other Linux distros. HOWTO: Cross-compile a Go app for Windows from Linux 2014/10/09 2014/10/09 OneOfOne 3 Comments I recently needed to test some app on windows, and while cross-compiling in Go is straight-forward, the app had some C code and apparently on Arch … However that's only true for projects written in pure Go. The most prominent program is remoteAudio, a low latency, multi user audio streaming application. Ask Question Asked 3 years, 8 months ago. After the successful compilation, we find the binary in the current directory of our host system and we can confirm that it has been built for arm64 (aarch64). In this post I will explain how you can cross compile your cgo project for multiple operating systems and architectures in a clear and structured manner. It’s customizable and easy to use. We select the same directory as our working directory with the -w. After generating our binary we automatically delete the container with the --rm flag. With the help of dpkg, the Debian Package Manager we can add additional architectures (e.g. Finally we have to set the PKG_CONFIG_PATH so that pkg-config uses the pkg-config files for our target architecture. It's the perfect tool for our cross-compilation chains. If you copy this file over to a Windows 32-bit host and run it: And if you try to run a 64 bit binary on a 32 bit Windows machine, you get an error saying that the exe is “is not compatible with the version of Windows you’re running”, as expected. This would just install the amd64 versions of those libraries. Instead of using the host's default C compiler (gcc), we want to use the previously installed cross compiler for arm64. How do I cross compile a Go project on Linux to generate an executable for running on Windows? Cross-compiling Golang in Bitbucket Pipelines. This is the Dockerfile for windows/amd64: Here we are installing the 3rd-party dependencies twice. How are GOARCH and GOOS used during go toolchain compilation?
