gcc测试
新建test.c文件：
#include<stdio.h>
#include<stdlib.h>
int main(void){
printf("Hello, world!\n");
system("pause");
return 0;
}
在命令行中cd到当前path，进行编译：gcc text.c -o test.exe即可运行test.exe
make测试
新建文件夹，在文件夹中新建max.c:
#include "max.h"
int max(int a, int b)
{
return a > b ? a : b;
}
max.h:
int max(int a, int b);
max_num.c:
#include <stdio.h>
#include <stdlib.h>
#include "max.h"
int main(void)
{
printf("The bigger one of 3 and 5 is %d\n", max(3, 5));
system("pause");
return 0;
}
makefile:
max_num.exe: max_num.o max.o
gcc -o max_num.exe max_num.o max.o
max_num.o: max_num.c max.h
gcc -c max_num.c
max.o: max.c max.h
gcc -c max.c
- gcc前是
tab而不是space
cd到当前文件夹后make
