golang调用dll/so(跨平台)

package main

import (
	"fmt"
	"github.com/besovideo/go4cpp"
	"log"
	"time"
)

func main() {
	go4cpp.InitLibrary([]byte("go data"), func(err error, data []byte) {
		log.Printf("=== %v %v", err, string(data))
	})

	var data = fmt.Sprintf("%v", time.Now().Format(time.RFC3339))
	go4cpp.Command([]byte(data), func(err error, data []byte) {
		log.Printf("+++ %v %v", err, string(data))
	})

	go4cpp.ReleaseLibrary()
}

说明:

1. dll/so 实现 include/go4c.h接口(参考lib/go4c.cpp)
2. 将dll/so复制到可执行程序目录(名称更改为go4c.dll/libgo4c.so)

export LD_LIBRARY_PATH=.
