Library not found for -lXXX
提问by Zugdud
If your trying to run an iphone project downloaded from the internet in Xcode and you encounter "Library not found for -lxxx", where -xxx is some third party library where would you look to set the library path? I am not sure where this is setup, in the SCM->library path is blank and everything else seems to match the configuration window for other working projects
如果您尝试在 Xcode 中运行从 Internet 下载的 iphone 项目，并且遇到“未找到 -lxxx 的库”，其中 -xxx 是某个第三方库，您将在哪里设置库路径？我不确定这是在哪里设置的，在 SCM->library 路径是空白的，其他一切似乎都与其他工作项目的配置窗口相匹配
When I look at the build log i see the following in the linker output:
当我查看构建日志时，我在链接器输出中看到以下内容：
-ObjC -ljson
-objC -ljson
How can i configure the project to not try to link in that library at build time?
如何将项目配置为在构建时不尝试链接该库？

if using cocoapodsand getting this error, try updating the cococapods$ sudo gem update cocoapods
Then update the pod for the project$ pod update
I don't know the exact reason but I think it was because the old version didn't set the libraries properly for the new XCode.
Hope this helps.
如果使用cocoapods并收到此错误，请尝试更新cococapods$ sudo gem update cocoapods
然后更新项目的 pod$ pod update
我不知道确切原因，但我认为这是因为旧版本没有为新版本正确设置库XCode。
希望这可以帮助。

Within the build tab of project settings there is a field for linker options, I removed the -ljson from here to solve the issue.
在项目设置的构建选项卡中有一个链接器选项字段，我从这里删除了 -ljson 以解决问题。

This might be helpful in some cases:
在某些情况下，这可能会有所帮助：
Xcode > Preferences > Locations > Locations > Advanced, select Unique.
I was facing a similar issue and chaging to "unique" from "legacy" solved the problem
我遇到了类似的问题，从“遗留”改成“独特”解决了这个问题
