objective-c – ld：找不到-lz的库

概述这让我发疯,当我尝试在模拟器上编译时,一切都很好,但在设备上我得到了这个错误： ld: library not found for -lzCommand /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/clang failed with exit code 1 请帮我理解问题的根源： Ld /Users/ZConsulting/L 这让我发疯,当我尝试在模拟器上编译时,一切都很好,但在设备上我得到了这个错误：

编辑：

我确实导入了libz.1.1.3.dylib框架：

我在linked框架中获得的唯一libz是libz.1.1.3.dylib

解决方法 您确实在linked frameworks和librarIEs项中指定了库libz.dylib,而不是直接引用libz.1.1.3 – 通常您应该使用库的最通用版本进行编译而不是更具体的库

其次,确保libz.dylib存在于iOS SDK下 – 如果缺少,则可能是错误安装的SDK(重新安装应该修复).

即

find /Developer/Platforms -name libz.dylib

应该导致iPhoneOS5.0.sdk下libz.dylib的非空输出

另请参阅iPhone – Linker Error in Xcode 4.2 Preview的答案,这与此类似.
