Eclipse CDT C/C++: Include a header file from another project
提问by Tobber
I have two c++ projects in Eclipse CDT mainand shared. In sharedi have a header called calc.h. I want to use this header in main, so i did the following:
我在 Eclipse CDT main和shared 中有两个 c++ 项目。在共享中，我有一个名为calc.h的标头。我想在main 中使用这个标题，所以我做了以下事情：
- added
#include "calc.hto the relevant files in main - In main's
properties -> Project referencesi checked of shared
- 添加
#include "calc.h到main中的相关文件 - 在main 中，
properties -> Project references我检查了共享
I hoped this would work, but I get a fatal error: calc.h: No such file or directorywhen compiling, so the project reference somehow doesn't work.
我希望这会奏效，但我fatal error: calc.h: No such file or directory在编译时得到了一个，所以项目参考不知何故不起作用。
I can get it to work by manually adding shared's source folder in main's properties->C/C++ Build->Setting->GCC C++Compiler->Includes, but my i have a bad feeling that this will become cumbersome on larger projects more complex dependencies. I'll therefore hoped that Eclipse could handle this via project references.
我可以通过手动得到它的工作将共享“中的源文件夹中的主要的properties->C/C++ Build->Setting->GCC C++Compiler->Includes，但我的我有一种不好的预感，这将成为较大的项目更加复杂的依赖关系繁琐。因此，我希望 Eclipse 可以通过项目引用来处理这个问题。
Am I missing something or is manually the only way?
我错过了什么还是手动是唯一的方法？

You are right, this his the way to do it !
你是对的，这是他的方式！
I use Eclipse CDT on large project, but I don't use the eclipse compilers settings. There are some drawbakcs to use the CDT compilers settings :
我在大型项目中使用 Eclipse CDT，但我不使用 Eclipse 编译器设置。有一些缺点可以使用 CDT 编译器设置：
- As you said, on large project, this is cumbersome.
- If you want to compile you project on a platform which doesn't have eclipse (when you deploy you application), that is not straightforward.
- 正如您所说，在大型项目中，这很麻烦。
- 如果您想在没有 Eclipse 的平台上编译您的项目（当您部署应用程序时），这并不简单。
I use CMake to manage my eclipse projects. When I start a new project, I do the following steps :
我使用 CMake 来管理我的 Eclipse 项目。当我开始一个新项目时，我执行以下步骤：
- In a terminal : Create a folder for your new project
- With your favorite text editor (vim, emacs, Text edit, kate ...) create the CMakeLists.txt of your project. You don't have to create an exaustive CMakeLists, just a small CMakeLists four your first files
- Then ask cmake to generate the eclipse project thanks to : cmake -G "Eclipse CDT4 - Unix Makefiles"
- Open eclipse, and click on File->Import, and choose "General/Existing project into workspace", then you can choose the folder created in the first step, and your project is ready to use in eclipse.
- 在终端中：为您的新项目创建一个文件夹
- 使用您最喜欢的文本编辑器（vim、emacs、Text edit、kate ...）创建项目的 CMakeLists.txt。你不必创建一个详尽的 CMakeLists，只需一个小的 CMakeLists 四个你的第一个文件
- 然后让 cmake 生成 eclipse 项目，感谢： cmake -G "Eclipse CDT4 - Unix Makefiles"
- 打开eclipse，点击File->Import，选择“General/Existing project into workspace”，然后就可以选择第一步创建的文件夹，你的项目就可以在eclipse中使用了。
CMake is THE compiler configuration tool to manage projects... If you don't know it I encourage you to discover it.
CMake 是用于管理项目的编译器配置工具......如果你不知道它，我鼓励你去发现它。
Cheers !
干杯！
