问题描述
我刚刚继承了一些用一个 cpp 文件编写的糟糕的 C++ 代码,该文件包含主函数和一堆其他函数.还有 .h
文件包含类及其函数定义.
I've just inherited some C++ code that was written poorly with one cpp file which contained the main and a bunch of other functions. There are also .h
files that contain classes and their function definitions.
到目前为止,程序是使用命令g++ main.cpp
编译的.现在我已经将类分离为 .h
和 .cpp
文件,我是否需要使用 makefile 或者我仍然可以使用 g++ main.cpp
命令?
Until now the program was compiled using the command g++ main.cpp
. Now that I've separated 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
列出 main.cpp 之后的所有其他 cpp 文件.
list all the other cpp files after main.cpp.
即
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"文件链接在一起.
Or you can compile them all individually. You then link all the resulting ".o" files together.
这篇关于使用 G++ 编译多个 .cpp 和 .h 文件的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持编程学习网!
