交叉编译jrtplib 问题

 

转载地址：http://blog.youkuaiyun.com/laotie1015/article/details/8252609

 

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

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
