我试图做一个简单的类program,但我得到一个奇怪的错误,从我看到的不是代码问题,而是与Clion有关的问题。编译过程中的Clion编译器错误

即使使用g ++直接编译我多个对象定义错误。它在Visual Studio中工作过。
C:\Users\fsa\CLionProjects\McMaster\Assignment_4>g++ Q_1.cpp clock.cpp box.cpp -o Q1.exe
C:\Users\fsa\AppData\Local\Temp\ccmD1R6t.o:box.cpp:(.bss+0x0): multiple definition of `Box::objectCount'

我正在用错误的命令编译。它应该是'g ++ Q_1.cpp clock.cpp box.cpp -o Q1.exe' –
那么现在编译成功了吗? – GigaRohan
@GigaRohan不,但它确实改变了错误输出。在我的课堂文件没有编译之前。现在我有'Box :: objectCount'错误的多重定义。我通过代码来查看原因。 –
