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
