我尝试从http://www.webalice.it/fede.tft/serial_port/serial_port.html
编译BufferedAsyncSerial.cc
但是当我把：
g++ -lboost_system -pthread -Wall BufferedAsyncSerial.cc -o BufferedAsyncSerial
我收到错误：
/tmp/ccrgsd5L.o: In function `main':
BufferedAsyncSerial.cc:(.text+0x9c): undefined reference to

collect2: error: ld returned 1 exit status
我仅在BufferedAsyncSerial.h引用#include "AsyncSerial.h"中添加了BufferedAsyncSerial.cc中的引用，从#include "AsyncSerial.h"更改为#include "BufferedAsyncSerial.h"
任何人都知道如何修复它？
