请教个编译jrtplib的问题！
我从网上下载了 jrtplib-3.7.1.tar.bz2 和jthread-1.2.1.tar.bz2,
解压;
进入jthread-1.2.,
root@ubuntu:/home/jiangmb/test_dir/jrtplib/jthread-1.2.1# ./configure --prefix=/home/jiangmb/test_dir/jrtplib/ --host=arm-montavista-linux CC=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc CXX=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-g++
生成makefile，然后make ,make install 编译通过！
但编译jrtplib时，
root@ubuntu:/home/jiangmb/test_dir/jrtplib/jrtplib-3.7.1# ./configure --prefix=/home/jiangmb/test_dir/jrtplib/jrtpinstall/ --host=arm-montavista-linux CC=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc CXX=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-g++
生成makefile，然后make，提示如下错误，请大家帮忙看一样，为什么？应该不止一个人遇到和我同样的问题的吧！
