弱问:在QT下有谁使用过JRTPLIB库吗? [复制链接]

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 -project 2. 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:

[root@localhost test]# qmake -project
[root@localhost test]# ls
jrtplib jthread main.cpp test.pro
[root@localhost test]# qmake
[root@localhost test]# ls
jrtplib jthread main.cpp Makefile test.pro
[root@localhost test]# make

难道是编译jrtplib时候有错误?我编译jrtplib的时候执行的命令为:1. ./configure 2. make 3.make install
编译jthread时,也是上面三步,但执行make install 的时候有点小问题,请大伙给分析一下.

两个类库编译过程:

1.jrtplib
最后执行完make install 后的一些代码
make[2]: Entering directory `/root/test/jrtplib/examples'
make[2]: Nothing to be done for `install-exec-am'.
make[2]: Nothing to be done for `install-data-am'.
make[2]: Leaving directory `/root/test/jrtplib/examples'
make[1]: Leaving directory `/root/test/jrtplib/examples'

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。
