您可以使用一个命令，假设所有需要的.cpp和.h文件都在同一个文件夹中。

g++ *.cpp *.h -Wall && ./a.out

它将同时编译和执行。

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

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

你仍然可以直接使用g++，如果你想:

g++ f1.cpp f2.cpp main.cpp

其中f1.cpp和f2.cpp是包含函数的文件。有关如何使用make进行构建的详细信息，请参阅优秀的GNU make文档。

~/In_ProjectDirectory $ g++ coordin_main.cpp coordin_funcc .cpp coordinator .h . cn

~/In_ProjectDirectory $ ./ a.t out .

使用Linux Mint和Geany IDE

当我将每个文件保存到同一目录时，一个文件没有在该目录中正确保存;坐标文件。h。重新检查，它被保存为坐标。h，而不是->坐标。h。gch。那些小事。 Arg ! !

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)。
