You can easily cross-compile this for a Raspberry Pi and run it there: $ env GOARCH=arm64 GOOS=linux go build -o hello-world main.go. Join the global Raspberry Pi community. hello-world Go application. Consider the following simple hello-world Go application: You can easily cross-compile this for a Raspberry Pi and run it there: As long as we are writing applications which do not need cgo this works very well. All of the following information is based on go version go1.14.7 darwin/amd64.. A list of valid GOOS values (Bold = supported by go out of the box, ie. Network updates. Raspberry Pi GPIO Pinout by When you’re done it’s going to look something like this… (an easy way to make sure you have it right is to … On archlinux we can install aarch64-linux-gnu-gcc and also pass the name of the compiler to the go build-command: As I noted at the beginning, I want to use $ env GOARCH=arm64 GOOS=linux go build -o hello-world main.go, $ env GOARCH=arm64 GOOS=linux CGO_ENABLED=1 go build -o cgo main.go, Closure on Loop Variables — C# and JavaScript Comparison, FizzBuzz in MySQL Using Stored Procedures, How to create a interative map using Plotly.Express-Geojson to Brazil in Python, 9 Python 3 Features You Might Not Use Yet, Where Do Mojibakes Come From? Afterwards I tried to cross-compile my application for armv7 . without the help of a C compiler, etc.). The problem is that these are not for the cross-compile toolchain. aix; android; darwin; dragonfly Go (Golang) GOOS and GOARCH. If you want to install Go on your Raspberry Pi you have a few options. Compiling on a Raspberry Pi is quiet slow compared to my laptop, which is already running for some years. To get the latest version, browse on over to the Go download page and look for the latest version. Open up your ~/.profile (Using nano, vi, etc). To cross-compile for the Raspberry Pi 3 or 4, use GOARCH=arm64. The newer API is sufficiently different that reworking thislibrary to use that API is not practical. To cross-compile my application for armv7 I have used the precompiled toolchain from archlinuxARM and added the environment variables PKG_CONFIG_DIR, PKG_CONFIG_LIBDIR and PKG_CONFIG_SYSROOT_DIR. Install Go (golang) pi@pi3-2:~ $ sudo apt update pi@pi3-2:~ $ sudo apt install golang. Instead I have written a new library,gpiod, that provides the samefunctionality as this library but using the GPIO character devi… The sysfs GPIO interface has been superceded in the Linux kernel by the GPIOcharacter device. For instance at the time of this writing, an updated Raspberry Pi OS shows a version of 1.11.1 in the repositories. Let’s mount the file system of the sdcard which is normally used by the Raspberry Pi and pass the path to the go compiler: Of course we could copy the content of the Raspberry Pi’s file system somewhere on our disk so we don’t have to mount the sdcard all the time and keep the Raspberry Pi running while we are cross-compiling. After building a new gokrazy image on your computer, you can easily update an existing gokrazy installation in-place thanks to the A/B partitioning scheme we use. Cross-compiling Go applications could get quiet challenging when we have dependencies to modules which depend on cgo and on C-libraries. I’d like to share the different ways how to cross-compile Go for the Raspberry Pi. You can also find an excellent installation guide there should you need help. tutorials{"@context":"","@type":"TechArticle","headline":"How to Install Go on the Raspberry Pi","url":"https:\/\/\/tutorials\/raspberry-pi\/install-go-raspberry-pi\/","datePublished":"2020-06-02","description":"If you want the latest version of Go on your Raspberry Pi, here's a quick tutorial that can help. I. Login to your user on the Raspberry Pi (I'm using the default user pi). III. Yes cross-compiling could finally speed up my development workflow and is quiet easy for Go when there are no dependencies to cgo or even libraries used by cgo. The above command will tell the compiler that we’re building for Linux and the ARM architecture. Long story short: I had to learn that Go is using its own pkg-config (see docs) to gather build dependency information. Look for the “ARM v6 version” for the Raspberry Pi. This library relies on the sysfs GPIO interface which is deprecated in the Linuxkernel and is due for removal during 2020. We also have a Raspberry Pi running the aarch64 architecture and having the libraries installed. I’m currently writing a small Go application which has a gui implemented by using as library for gtk bindings. Once you’ve got the operating system installed, make sure you can login, and have a working wired or wifi internet connection. Published: Jun 2, 2020 by Jeremy Morgan. Cross-compiling Go-applications for other architectures like aarch64 is quiet easy. Without sysfs, the watch/interruptfeatures of this library will no longer work. However, you’re likely to find an older version. Install the Raspbian OS which can be downloaded from the official Raspberry Pi site. Whichever archive you choose, use wget to download it: Now you’ll want to extract the package into your local folder: Now you just need to configure it, which you have to do with any Go installation anyway. Step 1: Get the Latest Package. II. So let’s implement a small user interface and cross-compile it for the Raspberry Pi: So what went wrong here? Let’s assume the necessary libraries are installed on the x86 system we’re working on. Instead, when you go to build, execute the following command: env GOOS=linux GOARCH=arm GOARM=5 go build. Create a working directory for all your go projects in your $HOME directory. In the past there was a lot of cross compiling and hacking to get it done, but now you can install it through Apt. However the current version is 1.14.3 so if the latest version is important to you, here’s your solution. The Raspberry Pi is a tiny and affordable computer that you can use to learn programming through fun, practical projects. Whichever archive you choose, use wget to download it: My current archive is Notice here you can set your go path to whatever you like. Why don’t I just cross-compile the application on my laptop. Now you can go ahead and start turning lights on and off! Mostly Coherent Ramblings of a Silicon Forest Tech Geek. Look for the “ARM v6 version” for the Raspberry Pi. Now I’m compiling successfully for armv7 using the following command: Archlinux directly offers the aarch64-linux-gnu-gcc as a package but this is not the case for the armv7 or other architectures and I don’t know whether or not the compilers are easily available on other distributions. To get the latest version, browse on over to the Go download page and look for the latest version.
