执行编译命令：
g -lboost_system-mt -i/home/base/boost_1_58_0 -l/home/base/boost_1_58_0/stage/lib client.cpp -o client出现错误提示：

collect2: ld returned 1 exit status经过测试有两种解决方法：
一、使用-lboost_system库
g -lboost_system -i/home/base/boost_1_58_0 -l/home/base/boost_1_58_0/stage/lib client.cpp -o client二、改变-lboost_system-mt的位置，在最后面添加一个-lboost_system-mt
g -lboost_system-mt -i/home/base/boost_1_58_0 -l/home/base/boost_1_58_0/stage/lib client.cpp -o client -lboost_system-mt
