CMake-代码::块-Hello World-基本示例 [英] CMake - Code::Blocks - hello world - basic example

问题描述

在哪里可以找到生成要在CMake中加载的CMake Hello World项目的指南？

Where can I find a guide to generate a simple CMake Hello World project to be loaded in CMake?

平台：Lenovo 32bit Linux Kubuntu

platform: Lenovo 32bit Linux Kubuntu

./git/CMakeLists.txt
./git/code/CMakeLists.txt
./git/code/hello-world.c

其中文件包含明显的内容

where the files contain the obvious content

- pointing the source to the git repo indicated in 1
- configuring the repo
- generating the code-blocs-project (cbp) file in ./build

中生成code-blocs-project（cbp）文件），所以我只需单击

- the cbp link in ./build
- compile the project in c::b and run a 
- very basic console program spitting out, you guessed it: "Hello stack overflowers!"

推荐答案

因此，只是为了确认文件的明显内容；这就是我所拥有的：

So, just to confirm the files' obvious content; here's what I have:

~/devel/example $ tree .
.
├── build
└── git
    ├── CMakeLists.txt
    └── code
        ├── CMakeLists.txt
        └── hello-world.c

3 directories, 3 files

~/devel/example $ cat git/CMakeLists.txt 
cmake_minimum_required(VERSION 3.0)
project(Hello)
add_subdirectory(code)

~/devel/example $ cat git/code/CMakeLists.txt 
add_executable(hello hello-world.c)

~/devel/example $ cat git/code/hello-world.c 
#include <stdio.h>

int main() {
  printf("Hello stack overflowers!\n");
  return 0;
}

现在，要运行CMake，我做了：

Now, to run CMake I did:

~/devel/example $ cd build/
~/devel/example/build $ cmake ../git -G"CodeBlocks - Unix Makefiles"

-- Build files have been written to: /home/fraser/devel/example/build
~/devel/example/build $ ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  code  Hello.cbp  Makefile

您可以看到已生成CodeBlocks项目文件（ Hello.cbp ）

which you can see has resulted in a CodeBlocks project file (Hello.cbp)

如果您现在打开此项目在CodeBlocks中（双击项目文件），您应该在左窗格中看到项目 Hello 。

If you now open this project in CodeBlocks (double click on the project file), you should see the project Hello on the left pane.

默认情况下，选择全部目标。它应显示在GUI顶部的编译器工具栏中的下拉框中。这样可以构建项目中指定的所有目标，但您无法运行它-您只能构建它。

By default, the "all" target is selected. It should appear in a drop-down box in the compiler toolbar at the top of the GUI. This builds all the targets specified in the project, but isn't something you can run - you can only build it.

可执行目标的名称为 hello，如CMake代码 add_executable（hello hello-world.c）。要运行可执行文件，请从前面提到的下拉框中选择 hello，然后在同一工具栏中单击生成并运行图标。

The executable target's name is "hello", as specified in the CMake code add_executable(hello hello-world.c). To run the executable, select "hello" from the drop-down box mentioned before, and then hit the "Build and run" icon in the same toolbar.
