../thelib/libthelib.so: undefined reference to `dlopen'

在Ubuntu下编译Crtmpserver出现如下错误

../thelib/libthelib.so: undefined reference to `dlopen'../thelib/libthelib.so: undefined reference to `dlclose'../thelib/libthelib.so: undefined reference to `dlerror'../thelib/libthelib.so: undefined reference to `dlsym'collect2: ld returned 1 exit statusmake[2]: *** [rtmpserver/rtmpserver] Error 1make[1]: *** [rtmpserver/CMakeFiles/rtmpserver.dir/all] Error 2

解决办法：打开builders/cmake下的CMakeCache.txt,修改DL_LIBRARY_PATH为DL_LIBRARY_PATH:FILEPATH=/lib/x86_64-linux-gnu/libdl.so.2

解决办法：

tinyxml.h 增加using namespace std;
