c++ - 如何在 libjingle 中编译 pcp 文件共享

Question

好的，我正在尝试使用以下命令编译名为“pcp”的文件共享示例

 wolfgang@den-pc:~/tejesh/libjingle-0.6.14/programs$ g++ -g -Wall -DPOSIX
-DEXPAT_RELATIVE_PATH -DFEATURE_ENABLE_SSL -DHAVE_OPENSSL_SSL_H=1  -I ../ pcp_main.cc
 ../talk/build/dbg/lib/libxmpphelp.a ../talk/build/dbg/lib/libjingle.a ../talk/build
 /dbg/lib/libexpat.a ../talk/build/dbg/lib/libsrtp.a -lpthread -lssl

我收到以下“typeinfo”错误...

 pcp_main.cc: In member function ‘virtual void
 CustomXmppPump::OnStateChange(buzz::XmppEngine::State)’:
 pcp_main.cc:348:12: warning: enumeration value ‘STATE_NONE’ not handled in switch  
 [-Wswitch]
 /tmp/ccVe8JUg.o:(.rodata._ZTI14CustomXmppPump[typeinfo for CustomXmppPump]+0x18): 
 undefined reference to `typeinfo for XmppPump'
 /tmp/ccVe8JUg.o:(.rodata._ZTIN7cricket18SessionManagerTaskE[typeinfo for  
 cricket::SessionManagerTask]+0x8): undefined reference to `typeinfo for buzz::XmppTask'
 /tmp/ccVe8JUg.o:(.rodata._ZTIN7cricket15SessionSendTaskE[typeinfo for  
 cricket::SessionSendTask]+0x8): undefined reference to `typeinfo for buzz::XmppTask'
 /tmp/ccVe8JUg.o:(.rodata._ZTI17AutoPortAllocator[typeinfo for AutoPortAllocator]+0x8): 
 undefined reference to `typeinfo for cricket::HttpPortAllocator'
 collect2: ld returned 1 exit status

有人对这个问题有什么想法吗？

如果你用gyp编译，你可以更改trunk/talk/libjingle_examples.gyp:

# target pcp
{
  'target_name': 'pcp',
  'type': 'executable',
  'dependencies': [
    'libjingle_xmpphelp',
    'libjingle.gyp:libjingle',
    'libjingle.gyp:libjingle_p2p',
  ],
  'sources': [
    'examples/pcp/pcp_main.cc',
  ],
},  # target pcp

再次运行 gclient runhooks 并制作。
