Exit status 1 Error compiling for board Arduino Uno

[menna112]

hi ,could anyone elp me find why this error happened?

[van_der_decken]

Sure, once you show us the actual error.

And please, as requested in How to get the best out of this forum, don't use screen shots for code (or errors for that matter). The harder you make it for people to help you, the fewer people will be inclined to do so. Use the <CODE/> tool in the message toolbar.

[PerryBebbington]

Look very carefully in the loop function at the first line of code.

I would quote it, but that's impossible from a screen shot.

[menna112]

#include<SR04.h>

int trig_Pin =12;
int echo_pin =11;
SR04 sensor = SR04(echo_pin,trig_pin);
long distance;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  delay(1000);

}

void loop() {
  // put your main code here, to run repeatedly:
  distance= sensor.Distance():
  Serial.println(distance);
  delay(1000);

}
exit status 1

I'm sorry but you still haven't shown the error. And I don't know what library you're using. So I was unable to compile your sketch to see what the error was.

But if you had shown the error, I imagine it would have looked like this:

/home/me/Documents/sketchbook/Uno_R3/test/test.ino: In function 'void loop()':
/home/me/Documents/sketchbook/Uno_R3/test/test.ino:21:17: error: expected ';' before ':' token
   distance= sensor.Distance():
                              ^

And if that is indeed your error, the compiler is telling you exactly what you did wrong. Putting a little effort into reading the error messages goes a long way.

@menna112 ,

Your other topic on the same subject deleted.

Please do not duplicate your questions as doing so wastes the time and effort of the volunteers trying to help you as they are then answering the same thing in different places.

Please create one topic only for your question and choose the forum category carefully. If you have multiple questions about the same project then please ask your questions in the one topic as the answers to one question provide useful context for the others, and also you won’t have to keep explaining your project repeatedly.

Repeated duplicate posting could result in a temporary or permanent ban from the forum.

for library

[van_der_decken]

Do you by any chance have non ASCII characters in your OneDrive path name? If so, you've run into this error:

Spurious "No such file or directory" error when library's path contains post-ASCII characters

And here's a workaround from @ptillisch:

Have library error eventhough installed

Hi @farahm_43. As was mentioned earlier in this thread by @van_der_decken, unfortunately there is a bug in the sketch compiler that causes it to fail to find the library when it is installed under a path that contains this sort of character. The workaround will be to configure Arduino IDE to use a different path to store libraries. I'll provide instructions you can follow to do that: Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus. The "P…

hi . i tried change location and found this error massage appear

i dont understand that Adafruit_Sensor.h . i didnt use that in my code

Hi @menna112. Just as you use libraries in your sketch code, libraries may use other libraries. When you are using one of the libraries that does this, it is necessary to install the other libraries on which the library depends in addition to the library you are using directly in your sketch.

The "DHT sensor library" library has a dependency on the "Adafruit Unified Sensor" library (which contains the Adafruit_Sensor.h file). You don't have the "Adafruit Unified Sensor" library installed, so the compilation fails with this "No such file or directory" error.

You can solve it by installing the missing library.

I'll provide instructions you can follow to do that:

1. Select Sketch > Include Library > Manage Libraries... from the Arduino IDE menus.
   The "Library Manager" dialog will open.

2. Wait for the update to finish, as indicated by the progress bar at the bottom of the "Library Manager" dialog.

3. Type Adafruit Unified Sensor in the "Filter your search..." field.

4. Press the Enter key.

5. Scroll down through the list of libraries until you see the "Adafruit Unified Sensor" entry. Click on it.
   A menu and button will appear at the bottom of the entry.

6. Click the "Install" button in the "Adafruit Unified Sensor" entry.

7. You may now get a dialog asking:

   Would you like to install also all the missing dependencies?

   If so, click the "Install all" button.

8. Wait for the installation to finish.

9. Click the "Close" button in the "Library Manager" dialog.
   The "Library Manager" dialog will close.

Now try compiling or uploading your sketch again. Hopefully this time you won't have any errors and everything will work as expected.

[menna112]

thanks it is finially work but there still a problem

i am sure it must till me numbers not that

#include <Adafruit_Sensor.h>

#include "DHT.h"
#include "DHT_U.h"


#define DHTPIN 2
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  Serial.println("humidity and Temperature");
  dht.begin();

}

void loop() {
  // put your main code here, to run repeatedly:
  delay(2000);
  float h=dht.readHumidity();
  float t=dht.readTemperature();
  Serial.print("humidity: ");
  Serial.print(h);
  Serial.print("Temperature: ");
  Serial.print(t);
  Serial.print(" c");
}
