每個live555元素的undefined參考

我從使用lib555編譯程序中得到這個錯誤。我看來，我失去了一些東西在Makefile：每個live555元素的undefined參考

testrtsp.o: In function `main': 
testrtsp.cpp:(.text+0x470): undefined reference to BasicTaskScheduler::createNew(unsigned int)' 
testrtsp.cpp:(.text+0x480): undefined reference to `BasicUsageEnvironment::createNew(TaskScheduler&)' 
testrtsp.cpp:(.text+0x49c): undefined reference to `Port::Port(unsigned short)' 
testrtsp.cpp:(.text+0x4b0): undefined reference to `RTSPServer::createNew(UsageEnvironment&, Port, UserAuthenticat 
ionDatabase*, unsigned int)' 

collect2: error: ld returned 1 exit status 
Makefile:64: recipe for target 'testrtsp' failed

我的Makefile文件看起來是這樣的：

# generated from pkg-config --cflags gstreamer-0.10

testrtsp: testrtsp.o              
      gcc -L. $(LDFLAGS) -o [email protected] $(LIVE_LIBS) $<         

      testrtsp.o: testrtsp.cpp             


       gcc -c $(CFLAGS) $(LIVE_INCLUDES) -o [email protected] $<

我包括我的程序所需的所有LIVE555頭。

編輯：右側的切斷應該是固定的

你縮進的是一個爛攤子，你可以請清理。此外，您的線條似乎在右側被切斷了一點。 – 2015-02-10 19:35:12

該解決方案非常簡單。我改變了這一點：

testrtsp:testrtsp.o              
gcc -L. $(LDFLAGS) -o [email protected] $(LIVE_LIBS) $<

這樣：

testrtsp: testrtsp.o              
gcc -L. $(LDFLAGS) -o [email protected] $< $(LIVE_LIBS)

這個解決方案並不適合我。對我來說，以錯誤的順序鏈接沒有工作，給了我很多未定義的參考。使用您在makefile中使用的相同順序適用於我=） – Micka 2015-06-29 11:13:14
