函数“ wiringPilSR”的隐式声明

Question

I'm trying to attach an interrupt to a pin using wiringPI's wiringPilSR . My code looks like this:

#include <wiringPi.h>
#include <stdio.h>

int inPin = 3;

void myInterrupt();

int main(vodi){
    wiringPilSetupGpio();
    pinMode(inPin, INPUT);
    wiringPilSR(inPin, INT_EDGE_RISING, &myInterrupt);
    while(1){
        printf("Cycle repeated\n");
        delay(1000);
    }
    return 0;
}

void myInterrupt(){
    printf("Interrupted");
    return 0;
}

When I try to build the code in Geany, I get a warning " implicit declaration of function 'wiringPilSR' " and error " undefined reference to 'wiringPilSR' ". I have set the build commands as shown in this tutorial on sparkfun

Answer 1

The function wiringPilSR isn't spelled with a lowercase L (l) , instead its 9th character is an uppercase i (I)

There goes one hour for figuring it out
