[SOLVED] I can't use "Serialprint" command for variables that change

Using Arduino Programming Questions

Hey, I am trying to learn some things in Arduino and I am having a problem, searched all the internet as much as I can but found nothing. Whenever I try to compile my code with "Serialprint" command it gives me that error:

Arduino:1.8.19 (Linux), Kart:"Arduino Uno"

during RTL pass: combine
/usr/share/arduino/hardware/archlinux-arduino/avr/cores/arduino/main.cpp: In function 'main':

Arduino Uno kartı için derleme hatası.

Here is my code if it helps:

#define trigPin 4
#define echoPin 2
long sure, mesafe;

void setup () {
Serial.begin(9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);

Serial.println("Arduino İle Mesafe Sensörü Uygulaması Başlatılıyor...");
delay(3000);
}
void loop () {
digitalWrite(trigPin, LOW);
delayMicroseconds(3);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);

sure = pulseIn(echoPin, HIGH);

mesafe = (sure/2) * 0.343;
Serial.print(mesafe);
Serial.println(" cm uzaklıkta");
delay(500);
}

Your problem doesn't appear to have anything to do with Arduino or your code, per se, but appears to be an internal compiler problem.

Can you try to compile this?

const byte trigPin = 4;
const byte echoPin = 2;

void setup ()
{
  Serial.begin(9600);
  pinMode(trigPin, OUTPUT);
  digitalWrite (trigPin, LOW);
  pinMode(echoPin, INPUT);

  Serial.println("Arduino");
  delay(3000);
}

void loop () 
{
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);

  unsigned long sure = pulseIn(echoPin, HIGH);
  long mesafe = (sure/2) * 0.343;
  Serial.print(mesafe);
  Serial.println(" cm");
  delay(500);
}

Your sketch compiles without error or warning for me on a Macintosh. It looks like there is something going wrong in your Arduino installation.

4

mesafe = sure / 59;

5

You might be right. This code showed me the same error too.

6

Yep, this is an example code from the internet and there are people who tells that code is fine so it definitely is about me. What can I do to fix my Arduino installation. I am in Manjaro btw, if that helps.

Re-install? Get the latest supported build from https://www.arduino.cc/en/software
After installing, go to Tools -> Board: -> Boards Manager... and update any board packages that appear when you set "Type" to "Updatable".

8

Those two lines are not equivalent.

I didn't have any issues on Linux mint 17.3
This was using IDE 1.8.19 from the 64 bit Linux tar ball

Where did you get your IDE from?
Can you turn on verbose output and post it so we can see what toolset is being used and all the command line options?

These days it is a total PITA the way the IDE works since you can longer be assured what toolset you end up using since add on packages for additional boards (like add adding board support for additional AVR boards) can alter the tool set used by boards outside that package.
i.e. add package X to the IDE to add support for board A and it can override the toolset and potentially break builds for previously installed package Y when building for board B.

IMO, this is a terrible "feature" that was added to the IDE and is just plain wrong headed.
IMO, board packages should be independent and should not have the capability to break builds for boards in other separate/independent board packages.

Hey, I just downloaded another one from "Boards Manager". I used "Arduino AVR Boards" instead of "Arch Linux Arduino AVR Boards" and no idea why but it works perfectly fine now.

Thanks everyone who tried to help <3

of course. his line is incorrect.

12

So is yours, it is just incorrect in a completely different way, and the error has nothing to do with the problem OP is experiencing.

(Note: 0.343 / 2 is not equal to 1/59.)

13

Hey, it's fine guys. Thanks for correcting my code kolaha. No need to argue about it ^^

Note: 0.343 / 2 is not correct formula to calculate centimeter from ping microseconds

15

None of it is - there is no temperature correction.

16

Thank you for this. Had the exact same issue and also using Manjaro.
