window下golang生成静态库给C语言调用

buidmod为c-archive能在window下生成 ，c-shared则不行

1.golang生成c-archive静态库

main.go

package main

import "C"

func main() {}

//export Hello

func Hello() string {

	return "Hello"

}

//export Test

func Test() {

	println("export Test")

}

bd.bat

set GOARCH=amd64

set GOBIN=C:\gonew\go18\bin

set GOCHAR=6

set GOEXE=.exe

set GOHOSTARCH=amd64

set GOHOSTOS=windows

set GOOS=windows

set GOPATH=E:\GOPROJECT\

set GORACE=

set GOROOT=C:\gonew\go18\

set GOTOOLDIR=C:\gonew\go18\pkg\tool\windows_amd64

set CC=gcc

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

set CXX=g++

set CGO_ENABLED=1

%GOBIN%/go build -x -v -ldflags "-s -w" -buildmode=c-archive -o main.a main.go

生成main.a 以及main.h

2.window下使用mingw64 gcc调用main.a

main.c

#include <stdio.h>

#include "main.h"

void main()

{

    GoString str;

    str = Hello();

    Test();

    printf("%d\n",str.n);

}

bdc.bat

gcc -o main.exe main.c main.a -lwinmm -lstdc++ -lws2_32 -lntdll

生成main.exe
