Go on ARM 32bit and 64bit resources and groups

[Norbert Fuhs]

Hi,

since I'm running Go on an Rapberry Pi 3 I would like to know if there are more official resources / tutorials or even groups?

Beside doing searching for arm on Github https://github.com/golang/go/search?utf8=%E2%9C%93&q=arm&type=

Is the only offical resource I found is Go s wiki page: https://github.com/golang/go/wiki/GoArm ?

I'm not sure how up to this wiki is I still doesn't mention it it benchmarks the Raspberry Pi 3 which I use and it seems not mauch people are using Go on an Pi.

I know its just a pet project by me but I wonder if there is a better place if I have specific go question I get now like
GC issuses with 32 Bit ARM ??

I think it's fine to ask questions about 32bit implementations of Go here. For Go specific things like interfacing with hardware https://gobot.io/ or https://periph.io/ may be better choices.

Is there anything specific you are looking for ? I extensively use go on pi and pretty much everything is very similar, i develop on my mac book and CI cluster deploys it. On non arm arch, its just as simple as setting up GOARCH and GOARM variables... thats all

I have a whole build/ci stack as well as scheduler stack (nomad + lxc) thats build, deploys and test arm/go binaries on them, the build cluster is 8 pi stacked up together.   

I also use go + pi to control my reef tank (http://reef-pi.com). There are handful (15-20) other folks who also uses that software, but not go developers, they are just reef keepers.

Forgot to mention, gobot, embd all are fairly good bindings. For most thing Pi related you can you can do straight I/O againsgt sysfs. Gobot provides decent i2c & spi based sensor/breakout board bindings, while embd provides most popular adafruit breakout board drivers (i2c/spi).

Several other sensors (like ds18b20) are 1 wire based and interaction is same as gpio (I/O against sysfs).

Thanks for all the answers and replys it helped me a lot the thing that confuses me is that there are not many resources for using Go on Raspberry Pi although many Gophers seem to use Go on a Pi for pet projects... I will set up my own repo with resources and links I find it a bit hard for Go beginners using Go on Raspberry Pi

Slightly different question... would this ARM approach work on a Samsung Chromebook Plus which uses OP1 ARM, with Crouton installed?

[Norbert Fuhs]

I don't have a chrome book but if its already already installed you should be able to install it like with any other Linux distro:

Just follow  https://golang.org/doc/install

Download Go 1.9 ARM:

https://storage.googleapis.com/golang/go1.9.linux-armv6l.tar.gz

Then insde the the download folder run:

tar -C /usr/local -xzf go1.9.linux-armv6l.tar.gz

Then add /usr/local/go/bin to the PATH environment variable.

You can do this by adding this line to your /etc/profile (for a system-wide installation) or $HOME/.profile:

export PATH=$PATH:/usr/local/go/bin

After you did this you need to run:

source /etc/profile


and after this


go version

It should print:

go version go1.9 linux/arm

To check if everything is installed correctly


If you have any trouble you can write me an mail

I built the openvg library and its clients on the Raspberry Pi. See:[ https://github.com/ajstarks/openvg

Other examples are in https://twitter.com/ajstarks/status/905198211274559488 

and referenced in https://speakerdeck.com/ajstarks/go-for-information-displays

In general I treat the Raspberry Pi like any other Linux box, building Go from source with each release.

[Dave Cheney]

Yes
