CMake - Code::Blocks - 你好世界 - 基本示例

CMake - Code::Blocks - hello world - basic example

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

平台:Lenovo 32bit Linux Kubuntu

1) 我将使用 git 存储库:

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

文件包含明显的内容

2) 我会 运行 cmake

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

3) 所以我只需点击

- 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!"

所以,只是为了确认文件的明显内容;这是我拥有的:

~/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,运行 CMake 我做了:

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

CMakeCache.txt  CMakeFiles  cmake_install.cmake  code  Hello.cbp  Makefile

您可以看到生成了 CodeBlocks 项目文件 (Hello.cbp)

如果您现在在 CodeBlocks 中打开此项目(双击项目文件),您应该会在左侧窗格中看到项目 Hello

默认情况下,"all" 目标是 selected。它应该出现在 GUI 顶部编译器工具栏的下拉框中。这会构建项目中指定的所有目标,但您无法 运行 - 您只能构建它。

可执行目标的名称是 "hello",如 CMake 代码 add_executable(hello hello-world.c) 中指定的那样。要 运行 可执行文件,从前面提到的下拉框中 select "hello",然后点击同一工具栏中的 "Build and run" 图标。
