标题:弱问:在QT下有谁使用过JRTPLIB库吗?

内容:
下载了Jrtplib类库,在redhat9.0下编译,都没有错误,打算建一个main.cpp文件:
#include "rtpsession.h"
int main(void)
{
RTPSession sess;
sess.Create(5000);
return 0;
}
保存后,利用终端进入存放该文件的目录test下,然后执行命令:1. qmake -project2. qmake 3.make 4. ./可执行文件
前面两步都没有问题,在第三步就出现了错误:
# qmake -project
# ls
jrtplibjthreadmain.cpptest.pro
# qmake
# ls
jrtplibjthreadmain.cppMakefiletest.pro
# make

很显然你的函数调错了，没有匹配的函数。
我猜你是看着网上某篇过时的文档写程序。
建议直接下jrtplib的官方文档，照着官方文档做。
另外，jrtplib源码包里有example，你可以先尝试编译那些东西。
