编译错误：
/usr/bin/ld: /tmp/ccYWdYju.o: undefined reference to symbol 'pthread_mutexattr_settype@@GLIBC_2.2.5'
/usr/lib64/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
解决办法：
链接加上 -L../boost/stage/lib -pthread
这是我的编译脚本：g++ Printer.cpp Client.cpp -o client -lIce -fPIC -rdynamic -L../boost/stage/lib -pthread
