使用G ++编译多个.cpp和.h文件 [英] Using G++ to compile multiple .cpp and .h files

问题描述

我只是继承了一些C ++代码，写得不好，一个cpp文件包含主要和一堆其他功能。还有 .h 文件包含类及其函数定义。

I've just inherited some C++ code which was written poorly with one cpp file which contained the main and a bunch of other functions. There are also .h files which contain classes and their function definitions.

直到现在程序使用命令 g ++ main.cpp 。现在我已经分类到 .h 和 .cpp 文件，我需要使用makefile或我仍然使用 g ++ main.cpp 命令？

Until now the program was compiled using the command g++ main.cpp. Now that I've seperated the classes to .h and .cpp files do I need to use a makefile or can I still use the g++ main.cpp command?

推荐答案

在main.cpp之后的其他cpp文件。

list all the other cpp files after main.cpp.

ie

g++ main.cpp other.cpp etc.cpp

等等。

或者你可以单独编译它们。然后，将所有生成的.o文件链接到一起。

Or you can compile them all individually. You then link all the resulting ".o" files together.
