Question

我是使用CImg和boost的新手。我将在下面分享的代码中获得未定义的符号引用，如下所述。

我正在使用此命令行来构建它：g ++ -lboost_filesystem -lboost_system -L / usr / X11R6 / lib -lm -lpthread -lX11 grayscaleConvertor.cpp＆amp;＆gt; errLog.txt

我在编译器命令中使用-l args。例如：-lboost_filesystem我在stackoverflow中的另一篇文章中读到了，但这并没有帮助解决boost :: filesystem :: symbols

找到CImg：/usr/include/CImg.h

找到boost：/ usr / include / boost（加上更多行）
