Golang on Onion Omega

  • B

    Does anyone know how one would go about cross compiling golang for the onion omega?

    @Ben-Goldberg Very good question. While this is something we haven't spent a huge amount of time on, we have played around with it a few months ago. This repo here: https://github.com/GeertJohan/openwrt-go offers openwrt buildroot with gccgo and libgo. You will need to clone the repo, check out branch add-gccgo-and-libgo, and run make menuconfig from there.

    The only problem right now is that the Omega profile isn't currently in this buildroot version, so you will to add support for it yourself. Here's a patch file that adds Omega support to the buildroot that we use:

    This patch adds support for the Onion Omega.

    I have a bunch of instructions on building and running Go on the Omega here. It's based on the info above.

    I know that this topic is quite old, but I thought it is worth mentioning that now you can compile Golang directly for mips.
    You would use something like:

    GOARCH=mipsle GOOS=linux go build main.go

    You can thus compile your program on any computer and just copy the resulting executable on your Onion.

    The resulting executable will be able to run on Onion directly.
