rtperrors.cpp: In function 'std::string RTPGetErrorString(int)':
rtperrors.cpp:225:36: error: 'snprintf' was not declared in this scope
make[1]: *** [rtperrors.lo] 错误 1
make[1]:正在离开目录 `/home/chenyu/chenyu/jrtplib-3.7.1/src'

make: *** [all-recursive] 错误 1

解决方法：src目录下找到rtpdefines.h文件，在里面加入：

#include <stdio.h> 
#include <stdarg.h> 
#include <string.h>

保存，再次编译，就可以了。。。。。。。。。。
