当转到名为arm.go的源文件时，无法识别任何标识符

Question

I believe this is a bug in the current Golang implementation, but I'm not completely sure.

Say I have two Go source files:

test1.go:

package tmp

func test1() {
    test2()
}

other.go:

package tmp

func test2() {}

They build with no errors; test2() is located in package tmp by test1()

However, if I rename other.go to arm.go, the compiler gives:

undefined: test2

... it's rather strange; any other name seems to work fine, except arm.go. Ideas?

Answer 1

arm.go file name is special (see http://golang.org/pkg/go/build/#hdr-Build_Constraints). The file will only be built on GOARCH=arm. I suspect you have different CPU, so the file is excluded.
