问题描述：

1、安装包：jrtplib-3.7.1.tar.gz jthread-1.2.1.tar.gz

2、步骤：分别解压两个安装包

进入jthread-1.2.1使用./configure -host=arm-linux CC=arm-linux-gcc CXX=arm-linux-g++ 命令配置

make

make install

同样进入jrtplib-3.7.1 使用同样步骤

3、错误信息

rtppollthread.cpp:(.text+0x484): undefined reference to `JThread::~JThread()'

rtppollthread.cpp:(.text+0x4a4): undefined reference to `JMutex::~JMutex()'

解决办法：手动链接

配置jrtplib的命令改为./configure -host=arm-linux CC=arm-linux-gcc CXX=arm-linux-g++ --with-jthread-include=/usr/local/include/jthread LDFLAGS=-L/usr/local/lib 就OK了
