iostest.bash fails for me right now with:

As @minux said, you may be setting CC=clangwrap.sh instead of CC_FOR_TARGET=clangwrap.sh.

Hmmm. I'm not setting any environment variables; I just ran iostest.bash, which appears to set CC_FOR_TARGET. Should I be setting some environment variable?

Also, can we detect this error directly and give a better error message?

Your error message is from the darwin/amd64 phase, trying to build a compiler for your host. Something must be off in your setup, try a normal ./all.bash?

A nicer error would be nice, but I do not expect normal users to go anywhere near iostest.bash. The intended way to build static libraries / native apps for iOS will be https://golang.org/x/mobile/cmd/gomobile. But we can get that working after the 1.5 freeze.

Normal all.bash passes.

Here are all possibly relevant entries from an env dump just before calling make.bash in iostest.bash:

CC_FOR_TARGET=/Users/jbleechersnyder/src/go-cmp/misc/ios/clangwrap.sh
GOROOT_BOOTSTRAP=/Users/jbleechersnyder/src/go-1.4
CGO_ENABLED=1
GOROOT=/Users/jbleechersnyder/src/go-cmp
GOOS=darwin
GOPATH=/Users/jbleechersnyder/go

Oh, I misread your transcript. You need to set GOARCH=arm.

(iostest.bash doesn't do that for you, because soon GOARCH=arm64 will be valid too.)
