我正在使用 SUP 做原生 iOS 应用程序。根据文档；我已经包含了库并在 Xcode 中给出了链接路径。构建时出现以下错误：

Undefined symbols for architecture i386:
  "_deflate", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in         libMo.a(tlplatcompress.o)
  "_deflateEnd", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a(tlplatcompress.o)
  "_deflateInit_", referenced from:
      StartCompression(enumCompressOperation, unsigned char, long (*)(void*, void*, long), void*, void**) in libMo.a(tlplatcompress.o)
  "_deflateParams", referenced from:
      StartCompression(enumCompressOperation, unsigned char, long (*)(void*, void*, long), void*, void**) in libMo.a(tlplatcompress.o)
  "_inflate", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a(tlplatcompress.o)
  "_inflateEnd", referenced from:

  "_inflateInit_", referenced from:
      StartCompression(enumCompressOperation, unsigned char, long (*)(void*, void*,  long), void*, void**) in libMo.a(tlplatcompress.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

请帮助我如何解决这个错误。我是使用 SUP 进行原生 iOS 开发的新手。

谢谢。

我也有同样的错误。

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

希望这对你有用。

注意：如果找不到libz.dylib ，请尝试添加libz.tbd

从 Xcode 7 开始，您应该这样做，而不是添加 libz.dylib：

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

lz链接选项

架构 i386 的未定义符号：

  "_deflate", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in         libMo.a(tlplatcompress.o)
  "_deflateEnd", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a(tlplatcompress.o)
  "_deflateInit_", referenced from:
      StartCompression(enumCompressOperation, unsigned char, long (*)(void*, void*, long), void*, void**) in libMo.a(tlplatcompress.o)
  "_deflateParams", referenced from:
      StartCompression(enumCompressOperation, unsigned char, long (*)(void*, void*, long), void*, void**) in libMo.a(tlplatcompress.o)
  "_inflate", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a(tlplatcompress.o)
  "_inflateEnd", referenced from:
      PlatCompress(enumCompressOperation, CompressCookie*, void*, long) in libMo.a(tlplatcompress.o)
  "_inflateInit_", referenced from:
      StartCompression(enumCompressOperation, unsigned char, long (*)(void*, void*,  long), void*, void**) in libMo.a(tlplatcompress.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我也有同样的问题，我认为你没有包含libz.dylib 库。

为此：

  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. 点击添加按钮。
