1 Overview

1.1 Hardware and Software

Hardware: BeagleBone Black

TI Processor SDK linux 2.00, factory image, sd card boot.

It is possible to use debian on BBB. I have tried it yet.

Go version: 1.5.1 official source tar ball.

1.2 Why

The official guide is generally good.

https://golang.org/doc/install/source

But there are some issues to be cleared on BBB build.

I didn't find a way to build Go toolchain and runtime (not Go app) from source by cross-compiling.

1.3 References

2 Issues

2.1 no space

Go uses /tmp as build folder. It is possible that either file block or inode space is not enough.

I hooked an 2T usb external hard drive to BBB and link /tmp to there.

2.2 libc.a not found

TI Processor SDK has no libc.a in /lib folder.

2.3 failed test 1

workaround: bypass this test.

2.4 failed test 2

runtime test

solution1:

go/src/cmd/dist/test.go

default timeout is 300 and timeoutScale is 2, that is 600s. change timeoutScale to 3 or more.

an (better) alternative way is set GO_TEST_TIMEOUT_SCALE to 3 or more, as pointed out in Dave Cheney's article.

3 How

tar xvzf xxx

tar xvf xxx

env GOROOT_FINAL=/tmp/final GOROOT_BOOTSTRAP=/tmp/go-linux-arm-bootstrap GOARM=7 GO_TEST_TIMEOUT_SCALE=5 ./all.bash
