I have this simple file:
$ cat goTest.go
package goTest
type Hello interface {
SayHello()
}
func CallJava(h Hello) {
h.SayHello()
}
I did a go mod init goTest in the directory.
And then I do a gomobile bind which failed:
$ gomobile bind -target=android -v
write /tmp/gomobile-work-794247297/src/go.mod

Steps I tried:
- change go version to 1.15.3 (I know this version works on another PC) and remove ~/go directory
- change gcc version to 9
