Linux development environment configuration experiment
The purpose of the experiment:
1.1 understand the application development process under the Linux operating system
1.2 master the use of the gun tool chain
1.3 master the gdb debugging skills
Experimental content:
Create a test user, and the password is also test.
After logging in with test, create the src directory, and all source code, intermediate code, and target code are placed in the / home / test / src directory.
Write a simple summation function that can solve the accumulated value from 0 to n, and store it in test2.c.
#include"test.h"
int test(int m)
{
int sum=a;
int i;
for(i=a;i<=m;i++)
{
sum+=i;
}
return sum;
}
Write a main function, store it in test1.c, ask to print the welcome message, and enter the value of n, print the summed value (function to call test2.c)
#include<stdio.h>
#include"test.h"
int main()
{
int n;
scanf("%d",&n);
printf("%d",test(n));
}
Write a header file, the macro defines some initial values, stored in test.h, for two functions.
#define a 0
int test(int);
Write a Makefile and generate an executable file test.
test:test1.o test2.o
gcc test1.o test2.o -o test
test1.o:test1.c test.h
gcc -c test1.c -o test1.o
test2.o:test2.c test.h
gcc -c test2.c -o test2.o
clean:
rm -rf *.o test
Next, let's take a look at the screenshot of the running result:
