Ninja & Make

Ninja & Make

ninja调试

ninja -v 打印执行的命令

一个小例子

test.c

	#include <stdio.h>
	int main()
	{
	    printf("%s", "Hello GCC\n");
	    return 0;
	}

CMakeLists.txt

	cmake_minimum_required(VERSION 3.1...3.21)
	project(test)
	add_executable(test test.c)

ninja编译，通过ninja -v 我们就可以看到执行的具体命令了

	mkdir build
	cd build
	
	cmake3 -GNinja ..

make 编译，make -n （通用方法，只打印命令，不执行）或者 make VERBOSE=1（部分适用）

-n, --just-print, --dry-run, --recon
