下载cmake 并安装

下面展示一些操作 内联代码片。

sudo apt-get update
sudo apt-get install cmakelove@ubuntu:~$ cmake

以下参考一下其他论坛的文档并实现测试
cmake 中文教程

第一个程序

源文件代码

#include <stdio.h>
#include <stdlib.h>/*** power - Calculate the power of number.* @param base: Base value.* @param exponent: Exponent value.** @return base raised to the power exponent.*/
double power(double base, int exponent)
{int result = base;int i;if (exponent == 0) {return 1;}for(i = 1; i < exponent; ++i){result = result * base;}return result;
}int main(int argc, char *argv[])
{if (argc < 3){printf("Usage: %s base exponent \n", argv[0]);return 1;}double base = atof(argv[1]);int exponent = atoi(argv[2]);double result = power(base, exponent);printf("%g ^ %d is %g\n", base, exponent, result);return 0;
}

CMakeLists.txt文件源码

# cmake lowest version required
cmake_minimum_required(VERSION 2.8)# project name
project(Demo_01)# assigned target object
add_executable(Demo_01 main.c)

在当前目录下执行cmake .，即可编译代码，可以查看整个编译过程

生成的makefile文件以及临时的文件如下

love@ubuntu:~/workspace/CMakeProject$ ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  CMakeLists.txt  main.c  Makefile

这里我们一一打开每个文件进行查看，用于了解其生成的原理及实质内容；
首先看makefile文件，其源代码如下：

最后执行make编译生成的可执行文件

love@ubuntu:~/workspace/CMakeProject$ make

[ 50%] Building C object CMakeFiles/Demo_01.dir/main.c.o
[100%] Linking C executable Demo_01

love@ubuntu:~/workspace/CMakeProject$ ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  CMakeLists.txt  Demo_01  main.c  Makefile
love@ubuntu:~/workspace/CMakeProject$ 

运行可执行文件测试

love@ubuntu:~/workspace/CMakeProject$ ./Demo_01 10 3
10 ^ 3 is 1000
