库编译libuv在OS X？ [英] Libraries to compile libuv on os x?

问题描述

我想学习一些libuv，似乎有通过它进入一个伟大的书。然而，这本书没有解释如何真正编译它。我跑了就了code，我从github上拉，并与GYP编译为在github上描述（的https： //github.com/joyent/libuv ）。但是我不知道我需要什么样的图书馆，包括获得code编译。我试图编译这个code：

I'm trying to learn some libuv and it seems there's a great book that goes through it. However, the book doesn't explain how to actually compile it. I ran make on the code that I pulled from github, and compiled with GYP as described on the github (https://github.com/joyent/libuv). However I'm not sure what kind of libraries I need to include to get the code to compile. I tried to compile this code:

/* first.c */
#include <stdio.h>
#include <uv.h>

int main() {
    uv_loop_t *loop = uv_loop_new();

    printf("Now quitting.\n");
    uv_run(loop, UV_RUN_DEFAULT);

    return 0;
}

我从 libuv 文件夹下面的命令编译它：

I compiled it with the following command from the libuv folder:

gcc -o first first.c build/Release/libuv.a

和我得到了以下缺失的符号：

and I got the following missing symbols:

有人可以给我如何建立一个libuv快速教程，或者如果有什么我需要什么？

Can someone give me a quick tutorial for how to build libuv, or if there's anything else I need?

推荐答案

OK，理解了它。我必须使用OSX的CoreFoundation和CoreServices框架。下面的命令成功编译：

OK, figured it out. I have to use the OSX "CoreFoundation" and "CoreServices" frameworks. The following command compiles successfully:

gcc -o first first.c build/Release/libuv.a -framework CoreFoundation -framework CoreServices
