每个live555元素的undefined参考

我从使用lib555编译程序中得到这个错误。我看来，我失去了一些东西在Makefile：每个live555元素的undefined参考

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文件看起来是这样的：

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头。

编辑：右侧的切断应该是固定的

你缩进的是一个烂摊子，你可以请清理。此外，您的线条似乎在右侧被切断了一点。 – 2015-02-10 19:35:12

该解决方案非常简单。我改变了这一点：

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

这样：

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

这个解决方案并不适合我。对我来说，以错误的顺序链接没有工作，给了我很多未定义的参考。使用您在makefile中使用的相同顺序适用于我=） – Micka 2015-06-29 11:13:14
