体系结构i386的未定义符号:"_deflate",从libMo.a中的PlatCompress(enumCompressOperation,CompressCookie*,void*,long)引用

Question

我正在使用SUP进行原生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.在构建获取以下错误时:

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:
      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)

请帮我解决这个错误.我是使用SUP进行原生iOS开发的新手.

谢谢.

Answer 1

我也有同样的错误.

将libz.dylib添加到目标框架 - > Build Phases选项卡 - > Link Binaries With Libraries,

希望这对你有用.

注意:如果找不到libz.dylib,请尝试添加libz.tbd

Answer 2

从Xcode 7开始,而不是添加libz.dylib,你应该这样做:

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

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. 去目标部分
2. 构建阶段选项卡
3. 链接二进制文件与库
4. 点击+按钮
5. 搜索libz.dylib
6. clcik on添加按钮.

Answer 4

1.到目标部分

2.Build Phases选项卡

3.Link二进制文件库

4.点击+按钮

5.search libz.tbd(或libz.dylib)

6.点击添加按钮.
