12 years ago Hello, Thanks for testing Go on a Pi. What does your swap configuration look like, 190mb of ram is close to enough to run the package tests, but will probably swap your machine into submission during the gc tests, (where it says # ../test). As a consolation, you can rerun most of the build phases independently. ie, to rerun the package tests go test std -test.short You can also rerun the gc tests, but be ready with your console cable or reset button as some require a lot of memory to run cd $GOROOT/test; go run run.go The math/rand timeout is an unfortunate side-effect of using the soft float emulation. If you apply, http://golang.org/cl/5987063/ and remove the GOARM environment variable, this will enable the hardware floating point support, and the test will likely pass. If this works for you, please, comment on the issue.

What steps will reproduce the problem? 1. export GOARM=5 2. cd go/src;./all.bash 3. compilation went fine but test step failed and hang the console. 4. Looks like a memory issue. 5. How do I build without "testing" step ? What is the expected output? test completed What do you see instead? # Testing packages. ok cmd/api 0.256s ? cmd/cgo [no test files] ok cmd/fix 28.627s ok cmd/go 0.340s ? cmd/godoc [no test files] ok cmd/gofmt 1.066s ?
