从Go的so文件中调用函数 [英] Calling functions in an so file from Go

问题描述

是否可以从Go调用静态对象(.so)文件? 我一直在Google搜寻，我一直在宣称我可以做到

Is it possible to call a static object (.so) file from Go? I've been searchign Google and I keep hitting upon the claim that I can do

lib, _ := syscall.LoadLibrary("...")

但是尝试这样做会出错

undefined: syscall.LoadLibrary

并通过Godocs搜索我无法在syscall包中找到对此功能的引用. 是否可以加载库并调用其函数?

and searching through Godocs I cannot find reference to this function in the syscall package. Is it possible to load a library and call its functions?

推荐答案

在POSIX平台上，您可以使用cgo调用

On a POSIX platform, you could use cgo to call dlopen and friends:

// #cgo LDFLAGS: -ldl
// #include <dlfcn.h>
import "C"

import fmt

func foo() {
     handle := C.dlopen(C.CString("libfoo.so"), C.RTLD_LAZY)
     bar := C.dlsym(handle, C.CString("bar"))
     fmt.Printf("bar is at %p\n", bar)
}
