golang cgo exit status 2 on Windows
问题
尝试
我想在安装了Go 1.8.1的Windows 8.1机器上编译以下代码片段。
package main
/*
int theAnswer() {
return 42;
}
*/
import "C"
import "fmt"
func main() {
fmt.Println(C.theAnswer())
}
这里是一个可工作的 Ideone Snippet 。
问题
在ideone上运行代码片段时，结果如预期。但是在我的机器上编译失败了：
$ CC=gcc GOARCH=amd64 GOOS=windows go build -x
WORK=C:\Users\****\AppData\Local\Temp\go-build775642990
mkdir -p $WORK\_\D_\dev\workspaces\go\src\github.com\nopmind\_obj\
mkdir -p $WORK\_\D_\dev\workspaces\go\src\github.com\nopmind\_obj\exe\
cd D:\dev\workspaces\go\src\github.com\nopmind
CGO_LDFLAGS="-g" "-O2" "C:\\Go\\pkg\\tool\\windows_amd64\\cgo.exe"
-objdir "C:\\Users\\****\\AppData\\Local\\Temp\\go-build775642990\\_\\D_\\dev\\workspaces\\go\\src\\github.com\\nopmind\\_obj\\"
-importpath _/D_/dev/workspaces/go/src/github.com/nopmind
-- -I "C:\\Users\\****\\AppData\\Local\\Temp\\go-build775642990\\_\\D_\\dev\\workspaces\\go\\src\\github.com\\nopmind\\_obj\\"
-g -O2 Test.go
go build _/D_/dev/workspaces/go/src/github.com/nopmind: C:\Go\pkg\tool\windows_amd64\cgo.exe: exit status 2
（$ go build -x 输出相同）
在没有任何有用结果的情况下，我已经谷歌了几个小时，现在陷入了困境。
环境
- 操作系统：Windows 8.1 x64
- Go版本：1.8.1
- MingW：通过WinBuilds安装的mingw-w64
问题
有人知道为什么会发生这种情况吗？
我个人猜测是MingW安装有问题。如果是这样，我希望能得到一个简短的解释，如何正确设置MingW以支持cgo。

Attempt
I want to compile the following snippet on my Windows 8.1 machine with Go 1.8.1 installed.
package main
/*
int theAnswer() {
return 42;
}
*/
import "C"
import "fmt"
func main() {
fmt.Println(C.theAnswer())
}
Here is a working Ideone Snippet.
Problem
Whilst running the snippet in ideone works as expected, the compilation on my own machine fails somehow:
$ CC=gcc GOARCH=amd64 GOOS=windows go build -x
WORK=C:\Users\****\AppData\Local\Temp\go-build775642990
mkdir -p $WORK\_\D_\dev\workspaces\go\src\github.com\nopmind\_obj\
mkdir -p $WORK\_\D_\dev\workspaces\go\src\github.com\nopmind\_obj\exe\
cd D:\dev\workspaces\go\src\github.com\nopmind
CGO_LDFLAGS="-g" "-O2" "C:\\Go\\pkg\\tool\\windows_amd64\\cgo.exe"
-objdir "C:\\Users\\****\\AppData\\Local\\Temp\\go-build775642990\\_\\D_\\dev\\workspaces\\go\\src\\github.com\\nopmind\\_obj\\"
-importpath _/D_/dev/workspaces/go/src/github.com/nopmind
-- -I "C:\\Users\\****\\AppData\\Local\\Temp\\go-build775642990\\_\\D_\\dev\\workspaces\\go\\src\\github.com\\nopmind\\_obj\\"
-g -O2 Test.go
go build _/D_/dev/workspaces/go/src/github.com/nopmind: C:\Go\pkg\tool\windows_amd64\cgo.exe: exit status 2
($ go build -x gives same output)
After googling for a few hours without any useful results I'm now hardstuck on this.
Environment
Question
Does anyone have a clue why this is happening ?
My personal guess is that something is wrong with the MingW installation. If so I'd appreciate a short explanation how to properly set MingW up for cgo.

你的代码适用于Windows 10、Windows 7和Linux。例如，在Windows 10上，可以使用TDM-GCC来进行MinGW编译。
Microsoft Windows [版本 10.0.15063]
>go version
go version devel +dc0f0ab Thu Apr 13 18:20:38 2017 +0000 windows/amd64
>gcc --version
gcc (tdm64-1) 5.1.0
>type answer.go
package main
/*
int theAnswer() {
return 42;
}
*/
import "C"
import "fmt"
func main() {
fmt.Println(C.theAnswer())
}
>go run answer.go
42
>
我从未使用过Win-builds。
