Building Go from source === If you don't already have some version of Go installed it's best to grab a bootstrap tarball built by 9legacy folks: cd /tmp hget http://www.9legacy.org/download/go/go1.14.1-plan9-amd64-bootstrap.tbz | bunzip2 -c | tar x Next, grab the source for the version of Go you want to build: hget https://golang.org/dl/go1.15.2.src.tar.gz | gunzip -c | tar x With the bootstrap and source ready to build we'll need to create a `GOROOT`. The usual location, and the one we'll use here, is `/sys/lib/go/$arch-$version`. Create the directory and bind the downloaded Go source directory over it, then change into the `src/` directory under the real `GOROOT` so that the correct path is picked up during the build: mkdir -p /sys/lib/go/amd64-1.15.2 bind -c go /sys/lib/go/amd64-1.15.2 cd /sys/lib/go/amd64-1.15.2/src Finally, we can start the build, making sure to set the `GOROOT_BOOTSTRAP` environment variable to the path where the bootstrap package is extracted: GOROOT_BOOTSTRAP=/tmp/go-plan9-amd64-bootstrap make.rc This will build the binaries under `$GOROOT/bin`. You can install these with: cp $GOROOT/bin/* /$objtype/bin or bind them with `/bin` in your profile: bind -b $GOROOT/bin /bin
