使用 Golang 1.10 编译 Windows DLL 时遇到问题答案

我在 Golang 1.10 中构建 Windows DLL 时遇到问题，此最新版本支持此功能：

main.goenv GOOS=windows GOARCH=386 go build -buildmode=c-shared main.go

can't load package: package main: build constraints exclude all Go files in [PATH]main.go

package main

import (
    "C"
    "fmt"
)

func main() {
    fmt.Println("from main")
}

//export Test
func Test() string {
    return "this is a test"
}
