CMake - Code::Blocks - Hello World - 基本示例

Question

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:联想32位Linux Kubuntu
1)我将使用 git repo:

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

文件包含明显内容的地方
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)所以我可以简单地点击

- 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!"

Answer 1

所以，只是为了确认文件的明显内容；这是我所拥有的:

~/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，为了运行 CMake，我做了:

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

~/devel/example/build $ ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  code  Hello.cbp  Makefile

您可以看到生成了一个 CodeBlocks 项目文件 ( Hello.cbp )

如果你现在在 CodeBlocks 中打开这个项目(双击项目文件)，你应该看到项目 Hello在左侧 Pane 中。

默认情况下，选择“所有”目标。它应该出现在 GUI 顶部编译器工具栏中的下拉框中。这会构建项目中指定的所有目标，但不是您可以运行的 - 您只能构建它。

可执行目标的名称是“hello”，如 CMake 代码中指定的 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”，然后点击同一工具栏中的“Build and run”图标。
