为C ++程序编写makefile

问题描述：

有人可以帮我写我的第一个makefile吗？

Can someone help me write my first makefile?

我有一个 helloworld.cpp c $ c> /path/to/main/code/helloworld.cpp 。
然后我刚刚包括一个.h文件 #includeSFML / network.hpp。

I have a helloworld.cpp code in /path/to/main/code/helloworld.cpp. And then I have just included a .h file #include "SFML/network.hpp".

现在SFML库保存在 / path / to / SFML / Library

Now SFML library is saved in /path/to/SFML/Library

可以帮助我开始在这。

It would be great if someone can help me getting started in this. In the mean time, I am trying to read thru the literature but its very overwhelming.

虽然你可能需要学习传统的GNU Makefile语法，为了与其他项目一起工作，我建议使用CMake为自己的项目，因为它更简单和更直观。

Although you may need to learn the traditional GNU Makefile syntax in order to work with other projects, I recommend using CMake for your own projects because it is simpler and more intuitive.

一个CMake文件在项目的根目录（与这种情况下的源相同）中存放一个名为 CMakeLists.txt 的文件，如下所示：

A CMake file for your example would go in a file called CMakeLists.txt in the root directory of your project (same as the source in this case) and look like this:

project(HelloWorld)                        # Name your project.
add_executable(helloworld helloworld.cpp)  # Specify an executable to build.
link_directories(/path/to/SFML)            # Tell it where your libraries are.
target_link_libraries(helloworld Library)  # Tell it which library to link.

如果你想要能够#include来自SFML的头文件而不包括每次的目录名称，你还可以写：

If you want to be able to #include headers from SFML without including the directory name every time, then you can also write:

include_directories(SFML)                  # Tell it where your headers are.

有关编写CMake文件和运行CMake的更多文档可在网站。

Further documentation on writing CMake files and running CMake is available on the website.

最后，CMake经常给出一个嘈杂但无害的消息请求您在CMakeLists.txt文件顶部放置一行：

Lastly, CMake often gives a noisy but harmless message requesting that you put a line like this at the top of your CMakeLists.txt file:

cmake_minimum_required(VERSION 2.8)        # Quell warnings.

干杯。
