您可以使用几个g++命令，然后链接，但最简单的是使用传统的Makefile或其他构建系统:如Scons(通常比Makefile更容易设置)。

when using compiler in the command line, you should take of the following: you need not compile a header file, since header file gets substituted in the script where include directive is used. you will require to compile and link the implementation and the script file. for example let cow.h be header file and cow.cpp be implementation file and cow.cc(c++ files can have extension .cpp, .cc, .cxx, .C, .CPP, .cp) be script file. Since gcc compiler notation for c++ file is g++, we can compile and link the files using

$g++ -g -Wall cow.cpp cow.cc -o cow.out

options '-g' and '-Wall' are for debugging info and getting warning for errors. Here cow.out is the name of the executable binary file that we can execute to run the program. it is always good to name your executable file otherwise name will be automatically given which might be confusing at times. you can also do the same by using makefiles, makefiles will detect, compile and link automatically the specified files. There are great resources for compilation using command line enter link description here

现在我已经将类分离为.h和.cpp文件，我需要使用makefile还是我仍然可以使用“g++ main.cpp”命令?

如果您打算将几个文件放入Makefile中，那么一次编译几个文件是一个糟糕的选择。

通常在Makefile (GNU/Make)中，这样写就足够了:

# "all" is the name of the default target, running "make" without params would use it
all: executable1

# for C++, replace CC (c compiler) with CXX (c++ compiler) which is used as default linker
CC=$(CXX)

# tell which files should be used, .cpp -> .o make would do automatically
executable1: file1.o file2.o

通过这种方式，make只正确地重新编译需要重新编译的内容。还可以添加一些调整来生成头文件依赖项——这样make也可以正确地重建由于头文件更改而需要重建的内容。

如果你想在cpp文件中使用#include <myheader.hpp>，你可以使用:

g++ *.cpp -I. -o out

.h文件将与编译无关…你只关心CPP文件…输入g++ filename1.cpp filename2.cpp main。cpp -o myprogram

意味着你正在编译每个CPP文件，然后将它们链接到myprogram中。

然后运行你的程序。/myprogram
