What did you do?

Trying to generate the java binding for my go file: Error:

gomobile bind -o ~/test.aar -target=android -androidapi=23 test || exit 1 gomobile: $GOPATH/bin/gobind -lang=go,java -outdir=/tmp/gomobile-work-628614164 test failed: exit status 1 2019/08/27 09:51:37 go [list -e -json -compiled=true -test=false -export=false -deps=true -find=false -tags – test]: exit status 2: # runtime/cgo gcc_android.c:6:25: fatal error: android/log.h: No such file or directory compilation terminated.

What did you see instead?

Error in generating the java binding.

Note: Before updating the gomobile same code was building.

Just to confirm:

I then removed strings.Count(stderr.String(), "\n") == 2 from /home/rkaufmann/go/src/golang.org/x/tools/go/packages and everything seem to work afterwards

Is it a flag we have to give while doing go get ?

It is safe to give GO111MODULE=off explicitly when go-getting gomobile/gobind. My guess is that you did go-get with modules. Then try:

GO111MODULE=off go get golang.org/x/mobile/cmd/gobind
GO111MODULE=off go get golang.org/x/mobile/cmd/gomobile
gomobile init

EDIT: module-aware go-get also installs binaries under $GOPATH/bin, so golang.org/x/mobile/cmd/gobind should work. 🤔

Could you try gomobile with GO111MODULE=off?
