ios 架构 i386 的未定义符号：“_deflate”，引用自 libMo.a 中的 PlatCompress(enumCompressOperation, CompressCookie*, void*, long)

Undefined symbols for architecture i386: "_deflate", referenced from PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a

I'm doing native iOS application using SUP.As per documentation; i have included the library and given the link path in Xcode. While building getting following error:

我正在使用 SUP.As per documentation 做原生 iOS 应用程序；我已经包含了该库并在 Xcode 中给出了链接路径。在构建时出现以下错误：

Please help me how to solve this error.I'm new to native iOS development using SUP.

Thanks.

谢谢。

I also had a same error.

我也有同样的错误。

Add libz.dylibto framework from the target -> Build Phases tab -> Link Binaries With Libraries,

从目标 -> 构建阶段选项卡 -> 将二进制文件与库链接，将libz.dylib添加到框架，

hope that will work for you.

希望这对你有用。

Note: If libz.dylibnot found, try adding libz.tbd

注意：如果找不到libz.dylib，请尝试添加libz.tbd

Starting with Xcode 7, instead of adding libz.dylib, you should do this:

从 Xcode 7 开始，您应该这样做，而不是添加 libz.dylib：

• Go to the project Build Settingstab
• Search for Other Linker Flags
• Add -lzas a linker flag (see screenshot)
• In the Productmenu, select Cleanbefore building again

• 转到项目Build Settings选项卡
• 搜索 Other Linker Flags
• 添加-lz为链接器标志（见截图）
• 在Product菜单中，Clean再次构建之前选择

I had also the same problem,I think you didn't include the libz.dylib library.

我也有同样的问题，我想你没有包含libz.dylib 库。

To do so:

这样做：

1. go to target section
2. Build Phases tab
3. Link Binaries With Libraries
4. click on + button
5. search libz.dylib
6. clcik on add button.

1. 转到目标部分
2. 构建阶段选项卡
3. 将二进制文件与库链接
4. 点击 + 按钮
5. 搜索 libz.dylib
6. 单击添加按钮。
