运行简单的 cgo 文件时遇到错误

Question

我正在尝试测试 cgo 代码。

package main

// #include <stdlib.h>

import (

    "C"

    "fmt"

)

func main() {

    fmt.Printf("test %d\n", int(C.random()))

}

D:\Dev\Go\src>go version 

go version go1.3 windows/amd64

D:\Dev\Go\src>go env 

set GOARCH=amd64 

set GOBIN= 

set GOCHAR=6 

set GOEXE=.exe 

set GOHOSTARCH=amd64 

set GOHOSTOS=windows 

set GOOS=windows

set GOPATH=D:\\Dev\\Go 

set GORACE= 

set GOROOT=c:\go 

set GOTOOLDIR=c:\go\pkg\tool\windows_amd64 

set CC=gcc 

set GOGCCFLAGS=-m64-mthreads -fmessage-length=0 

set CXX=g++ 

set CGO_ENABLED=1

D:\Dev\Go\src>go run test_binding.go

# runtime/cgo C:\Users\hyoon\AppData\Local\Temp\go-build779392087\runtime\cgo\_obj\_cgo_defun.c:7 6c: No such file  or directory: runtime.h

请检查最后一个错误。怎么了？

你从这个程序得到什么输出？package main/*#include <stdlib.h>*/import "C"import (&nbsp; &nbsp; "fmt")func main() {&nbsp; &nbsp; fmt.Printf("test %d\n", int(C.rand()))}
