创建一个libjson库来链接到xcode [英] creating a libjson library to link to xcode

问题描述

我为可能的noobish问题提前道歉，但我在互联网上的任何地方找不到这个答案或SO在过去几天的查找。

I apologize in advance for the possibly noobish question but I could not find the answer to this anywhere on the internet or SO for the past few days of looking.

我试图在xcode中创建一个c ++项目，我想使用libjson来解析我的json工作。不幸的是，我一直无法获得环境负荷。我尝试了方向，通过make文件。我跑make安装，并试图轻拂各种开关在这里和那里在make文件。我基本上试图遵循的方向，如一个建议这里：
如何创建一个libJSON库？

I'm trying to create a c++ project in xcode and I want to use libjson to parse my json work. Unfortunately, I have been unable to get the environment load it. I tried the directions and looked through the make file. I ran make install and tried flicking various switches here and there in the make file. I basically tried to follow directions such as the one advised here: How to create a libJSON library?

当我尝试运行make文件时，我一直在运行这个问题，我找不到在线解决方案： / p>

When I try to run the make file I keep running into this issue for which I could not find a solution addressing it online:

/usr/bin/ranlib: file: libjson.a(JSONAllocator.o) has no symbols
/usr/bin/ranlib: file: libjson.a(JSONDebug.o) has no symbols
/usr/bin/ranlib: file: libjson.a(JSONMemory.o) has no symbols
/usr/bin/ranlib: file: libjson.a(JSONNode_Mutex.o) has no symbols
/usr/bin/ranlib: file: libjson.a(JSONPreparse.o) has no symbols
/usr/bin/ranlib: file: libjson.a(libjson.o) has no symbols

没有符号是什么意思？

What does has no symbols mean? how could I compile it otherwise?

一个人建议直接添加库，但我不知道如何完成这些工作，并且不断得到编译错误。

One person suggested adding the libraries directly but I was not sure how to get that done and kept getting compile errors.

我尝试安装macport并成功获得jsoncpp安装，但无法找到libjson作为端口。我想最终使用libjson的c ++风格的接口。

I tried installing macport and successfully got jsoncpp to install but could not find libjson as a port. I want to end up using the c++ style interface for libjson.

我试图让它在XCODE上工作我在2009年早期的macbook intel core 2 duo上有os 10.8.5。

I'm trying to get it to work on XCODE I have os 10.8.5 on an old early 2009 macbook intel core 2 duo.

EDIT：以下是'make install'的输出：

Here is the output of 'make install':

推荐答案

项目进入我的xcode项目并构建它。它最终解决了这个问题。我仍然不知道为什么我不能使图书馆，并得到它的工作，但希望我会很快找到以及。

In the end, I tried just copying the entire source project into my xcode project and building it. it ended up solving the issue. I am still not sure why I could not make the library and get it to work but hopefully I will find out soon as well.
