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

要单独编译而不需要链接，你需要添加-c选项:

g++ -c myclass.cpp
g++ -c main.cpp
g++ myclass.o main.o
./a.out

在main.cpp之后列出所有其他CPP文件。

ie

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

等等。

或者您可以单独编译它们。然后链接所有结果”。O”文件一起。

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)。

我曾经使用一个定制的Makefile编译当前目录中的所有文件，但是我必须每次都将它复制到我需要的每个目录中。

所以我创建了我自己的工具-通用编译器，它使编译许多文件的过程更容易。
