A Docker build image for GCCGO cross toolchain for OpenWRT 15.05.
Target is a MIPS24K Gl.inet router.
You can find the binaries of the compilation here:
http://filez.zoobab.com/openwrt/gccgo-toolchain/ar71xx-glibc/
The toolchain contains mips-openwrt-linux-gnu-gccgo, mips-openwrt-linux-gnu-go, mips-openwrt-linux-gnu-gofmt and the go libraries:
You can build the complete OpenWRT with the Docker recipe like this:
$ docker build -t openwrt-15.05-go:latest .
The output is roughly 10GB.
You can also download the precompiled binary docker image from the docker hub (also 10GB):
$ docker pull zoobab/openwrt-15.05-go
And then run inside to find the toolchain:
$ docker run -i -t zoobab/openwrt-15.05-go:latest /bin/bash
You will find the toolchain under /home/openwrt/openwrt-15.05/staging_dir/toolchain-mips_34kc_gcc-5.3.0_glibc-2.19/bin .
Look at build.sh on how to build a hello.go with the toolchain.
