ld：找不到-lz.1.2.3的库

问题描述：

当尝试编译iOS 5的软件时，XCode 4.2会抛出错误：

When trying to compile the software for iOS 5, XCode 4.2 throws an error:

ld: library not found for -lz.1.2.3

我发现这篇帖子告诉我要替换1.2.3。 1.2.5

I found this post that tells me to replace 1.2.3. with 1.2.5

执行链接建议之后，它适用于XCode 4.2，但对于XCode的旧版本失败，错误

After doing what the link has suggested, it worked for XCode 4.2 but fails for older versions for XCode with the error

 ld: library not found for -lz.1.2.5

有没有人遇到过上述情况？如何解决这个问题，以便在不同版本的SDK之间不会失败？

Has anyone encountered the above situation? How can I resolve this so that it will not fail between the different versions of SDK?

答

只需使用-lz，就没有了需要使用版本化链接。所以从框架中删除libz-1.2.5.dylib并添加libz.dylib。

Just use -lz, there's no need to use the versioned link to it. So remove libz-1.2.5.dylib from frameworks and add libz.dylib.
