I tried ``` ./node_modules/.bin/electron-builder --arm --linux deb ``` And it failed with the message: ``` Unknown argument: arm ``` It also dumped all the permitted commands, as if I had specified “–help”, and there are clearly only two arm-related choices, which are: ``` --armv7l Build for armv7l [boolean] --arm64 Build for arm64 [boolean] ``` So, I’m going to try armv7l, just to see what happens. ---

When I try armv7l, I get the following, which seems like a lot of successful building followed by a failure to package, trying to run an x86 version of fpm on an arm machine. ``` pi@pi4:~/Documents/etcher $ ./node_modules/.bin/electron-builder --armv7l --linux deb Configuring yargs through package.json is deprecated and will be removed in the next major release, please use the JS API instead.

I’ve asked for help with this on the Raspberry Pi forum - perhaps they can help me get a working fpm installed, and then I can get back here to continue the build, trying @shaunmulligan’s tip about pointing to a local fpm. ---

Hello everyone, It seems that another user successfully built a debian package for rpi4, you can check the forum thread [here](https://forums.balena.io/t/install-etcher-on-a-raspberry-pi-4/43465) @futurejones If you’re willing to give some feedback about the issues you encountered and how you overcame them, even if they made you switch to another path, that would be highly appreciated so we can hopefully enhance the documentation with the missing pieces and/or investigate more! ---

In pursuit of getting a native fpm installed, I did the following: It seemed that I couldn’t get rubygems via apt because the debian/apt dependencies were messed up, so I got it the ruby way: `sudo gems update --system` This got me RubyGems 3.0.6 Install ruby header files: `sudo apt install ruby-dev` This then allowed me to install fpm, the package tool I think I need to package the .deb: `sudo gem install fpm` ---

After trying many different build combinations, including writing my own packaging script, I have found the following to be the most reliable and consistent method of building Etcher. This method has been tested on a fresh install of Raspbian Buster on a Raspberry Pi 4. **Build Instructions** 1. Install build dependencies. ```auto sudo apt-get install -y git python gcc g++ make libx11-dev libxkbfile-dev fakeroot rpm libsecret-1-dev jq python2.7-dev python-pip python-setuptools libudev-dev sudo apt-get install ruby-dev sudo gem install fpm -v 1.10.2 #note: must be v1.10.2 NOT v1.11.0 #install NodeJS curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash - sudo apt-get install -y nodejs ``` 1. Clone Repo and Checkout Release . ```auto git clone --recursive https://github.com/balena-io/etcher cd etcher git checkout v1.5.63 ``` 1. Install Requirements ```auto pip install -r requirements.txt ``` 1. Setup and Install NPM Modules . ```auto make electron-develop ``` At this point you should be able to run a test of Etcher with - ```auto npm start ``` 1. Patch Build Files ```auto # disable tiffutil in the Makefile as this is a Mac only app and will cause the build to fail sed -i 's/tiffutil/#tiffutil/g' Makefile # restrict output to .deb package only to save build time sed -i 's/TARGETS="deb rpm appimage"/TARGETS="deb"/g' scripts/resin/electron/build.sh ``` 1. Build and Package ```auto # use USE_SYSTEM_FPM="true" to force the use of the installed FPM version USE_SYSTEM_FPM="true" make electron-build ``` 1. Install Package ```auto # *.deb package will be in /etcher/dist/* # filename will depend on which release version was checked out sudo apt-get install ./dist/balena-etcher-electron_1.5.63+a1558116_armv7l.deb ``` Note: You can ignore the `chmod: cannot access '/opt/balenaEtcher/chrome-sandbox': No such file or directory` warning. It is caused by the `postinst` file and is only relevant for electron versions 5+. ---

FYI: @futurejones has a github site where he’s got the whole Etcher-on-a-Pi process nailed, and where he provides some easy scripts : install\_dependencies, build, and package\_etcher. See [here](https://github.com/futurejones/balena-etcher-arm/blob/master/etcher-build/README.md). ---

The Raspberry Pi 4 is the successor to the Raspberry Pi 3. It builds upon the Pi 3 by upgrading the ARM cores to Cortex-A72, offering up to 4GB RAM, USB 3.0, and gigabit ethernet. I did see mention of an A71, in the threads below, but not a 72? IMHO this device was released working on Raspbian, but somehow “green” Just the issues app developers are having with it. Octoprint barely works on a Pi4, for example. ---

I’m not a code jock, but I see known inconsistencies. x86 Architecture is a CISC (inline construction set chip. The ARM 64 chip is a true RISC chip (reduced instruction set chip) aka parallel processing. It is more of the “Alpha” “Power” “Itanium” “Sun” series of chips. The fact that ARM servers are replacing CISC servers, for untethered parallel processing power, is not to be overlooked. I’m just pointing out these things, porting from one chip architecture to another. That’s why the original Power Macs were such screamers. Parallel processing. The fact they ran MS Office (but the highest base of installed versions of MS Office) Still MS was a CISC company. Pushing to all PC/x86 manufacturers. But Mac is what kept them alive. I digress… These are things to truly consider when porting across architectures. Not known to be a piece of cake. We just all have access to the tools today. But what did the Alpha, Itanium & Power programmers really do to port NT4-5 to their platforms? Privately own software originally developed for VMS. AKA Posix. Posix is still in Win.xxx today. Another case of Mr. Gates silently slipping someone else’s code under his arm. [Previous page](https://forums.balena.io/t/trying-to-build-etcher-on-raspberry-pi-4/40213.md?page=2)
