"Compilation error: Error: 2 UNKNOWN: exit status 1" error message is unnecessarily cryptic #151

TheAnton205 · 2021-03-01T18:06:27Z

Describe the bug
Any program I run and attempt to compile I get this error:

c:/users/anton/appdata/local/arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/../lib/gcc/avr/7.3.0/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference to `main'
collect2.exe: error: ld returned 1 exit status
Compilation error: Error: 2 UNKNOWN: exit status 1

I recently got the beta and no matter what I do I had this (yes I restarted my pc) and I even download the latest Git (2.30.1) 64-bit.

To Reproduce
Steps to reproduce the behavior:

Open any code
Click compile

Expected behavior
Expected for the code to compile.

Desktop (please complete the following information):

OS: Windows 10 Pro 64-bit
Version: 2.0.0-beta3

Additional context
This could be due to from when some notification occurred which I couldn't figure out what it was for. I do remember that it led to this link. However, I don't see this notification anymore?

I have the same error. I installed first DallasTemperature library from library manager, and for OneWire library I do the same.

After that I tried compile code at the bottom of the page.
But it ending with Error 2 UNKNOWN: exit status 1.
After that I installed manually libraries from .zip archives. (that works for me for old IDE). The same error.

My OS is Ubuntu 20.10

#include <DallasTemperature.h>
#include <LiquidCrystal.h>
#include <OneWire.h>

#define ONE_WIRE_BUS 2

OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);

// Definicja wejść wyświetlacza ciekłokrystalicznego //definition of lcd output
LiquidCrystal lcd(4, 5, 6, 7, 8, 9);
void setup(void) {
  // Inicjacja czujnika //sensor initiation
  sensors.begin();
  // Inicjacja wyświetlacza //screen initiation
  lcd.begin(16, 2);
  lcd.clear();
}
void loop(void) {
  lcd.setCursor(0, 0);
  lcd.print("Temperatura:");
  lcd.setCursor(0, 1);
  sensors.requestTemperatures();
  lcd.print(sensors.getTempCByIndex(0));
  lcd.setCursor(6, 1);
  lcd.print("st.C");
  delay(1000);
}

I see. I'm not sure if it is due to libraries, I still get this error even from examples without library (File>Examples>Basics>Blink) still causes this error yet there are no libraries?

@TheAnton205 @Pioxis
have you installed any cores?

which board have you selected?
If the platform for the selected board is not installed you should get prompted to install it.

please try to manually add support for your board via the boards manager on the left sidebar or from the "Tools > Board > Boards Manager" menu

Additionally I get that info from my terminal, when Error appeared:

root ERROR Request compile failed with error: 2 UNKNOWN: no FQBN provided

When I first opened program I was prompted for select the board. I selected for Arduino UNO.
I have installed Arduino AVR Boards by Arduino, version 1.8.3

SOLVED:

For me I solved it by reinstalling the beta IDE and by reinstalling Arduino AVR Boards by Arduino, version 1.8.3

Everything seems working now, thanks.

Same issue here. A program that easily compiles and runs under the old IDE gets:

collect2.exe: error: ld returned 1 exit status Using library IRremote at version 3.0.3 in folder: C:\Users\ccbland\Documents\Arduino\libraries\IRremote Compilation error: Error: 2 UNKNOWN: exit status 1

when compiled with V2. No other discernable complaints when using verbose mode on compile.

I did uninstall/reinstall IDE 2.0 to no avail.

Here's my program

#include "IRremote.h"

const int IR_RECEIVE_PIN = 11;
long keyPressed;


void setup()
{
    //setup serial monitor
    Serial.begin(115200);

    //initialize IR Receiver
    IrReceiver.begin(IR_RECEIVE_PIN, DISABLE_LED_FEEDBACK);
}

void loop()
{
    //check to see if a button was pressed
    if (IrReceiver.decode())
    {
        //a button press was pressed and decoded

        //get the code of the key that was pressed
        keyPressed = IrReceiver.decodedIRData.decodedRawData;

        //if that code is from the power button, tell us
        if (keyPressed==0xBA45FF00) Serial.println("Power Key Pressed");

        //wait for things to settle down
        delay(700);

        //resume receiving button presses
        IrReceiver.resume();
    }
}

I think this is a case of bad error messages. I got the error too, "Compilation error: Error: 2 UNKNOWN: exit status 1" in the output window. I started the program from the console, and there I see:

daemon INFO /tmp/.arduinoIDE-unsaved2021316-1396774-1hhgvhh.m6o3/Blink/Blink.ino:1:10: fatal error: Servo.h: No such file or directory
daemon INFO  #include <Servo.h>
daemon INFO           ^~~~~~~~~
daemon INFO compilation terminated.
root ERROR Request compile failed with error: 2 UNKNOWN: exit status 1

If I install the servo lib everything is fine, so the error message in the output window is wrong.

ChuckBland · 2021-04-17T15:45:42Z

Patrik, I'd like to replicate what you've done. I'm not familiar with "starting from the console". How is that done? Chuck

I started the program from the command prompt in Linux. You can do the same with Windows Powershell . You go to the program installation folder and run the program by entering it's name. Then you see all log messages directly.

Very cool interface. Sadly I am no closer to solution. No complaints about Servo.h, which is fine since I'm not including it. Here's the errors when I compile. daemon INFO inventory.Store.ConfigFileUsed() C:\Users\ccbland\AppData\Local\Arduino15\inventory.yaml daemon INFO inventory.Store.ConfigFileUsed() C:\Users\ccbland\AppData\Local\Arduino15\inventory.yaml daemon INFO Searching tools required for board arduino:avr:uno daemon INFO Required tool [tool: {ToolName:"arduinoOTA",ToolVersion:"1.3.0",ToolPackager:"arduino"}] daemon INFO Required tool [tool: {ToolName:"avr-gcc",ToolVersion:"7.3.0-atmel3.6.1-arduino7",ToolPackager:"arduino"}] daemon INFO Required tool [tool: {ToolName:"avrdude",ToolVersion:"6.3.0-arduino17",ToolPackager:"arduino"}] daemon INFO Adding libraries dir [dir: C:\Program Files (x86)\Arduino\libraries, location: ide] daemon INFO Adding libraries dir [dir: C:\Users\ccbland\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.3\libraries, location: platform] daemon INFO Adding libraries dir [dir: C:\Users\ccbland\Documents\Arduino\libraries, location: user] daemon INFO Resolving include IRremote.h for arch avr daemon INFO found better lib [lib: IRremote, prio: 5E9] root ERROR Request compile failed with error: 2 UNKNOWN: exit status 1

Same issue here. Win 10 Pro 64 bits. Arduino Uno, Core installed (as suggested by the IDE itself). Can't compile anything, same error message.

jerabaul29 · 2021-06-18T12:52:19Z

Same error here, opening a detailed issue about it now.

jeromegirard · 2021-07-17T16:25:19Z

Same error here, but like @bphermansson, when I compiled with verbose, I saw the the error comes from a lacking library.
Add the library and everything is working fine.

d-i-ry · 2021-08-04T17:41:20Z

upgrading to Arduino IDE v2.0.0 beta 9 worked for me

pibondchem · 2021-08-13T17:05:31Z

I had this error specifically when I added

#include <LiquidCrystal.h>

in my code.

I'm using a Dell XPS, Windows 10

Arduino IDE
Version:2.0.0-beta.10
Date: 2021-08-05T08:23:32.577Z(1 week ago)
CLI Version:0.18.3 alpha [d710b642]

cirobruno · 2021-08-21T18:54:44Z

Same error!

Out or the blue, I couldn't compile anymore!

Now, as soon as I restart Arduino IDE, I get this message:
"Plugin runtime crashed unexpectedly, all plugins are not working, please reload the page. If it doesn't help, please check Theia server logs."
Wen trying to compile, "Compilation error: Error: 2 UNKNOWN: exit status 1".

So, I've update the board's extension to esp32 by Espressif Systems V1.0.6, getting
"Compilation error: Error: 2 UNKNOWN: exit status 1".

Then, after changing it to esp32 by Espressif Systems V1.0.5, the error became:
"bash: line 0: [: /Users/cirobruno/Documents/Arduino/Testes: binary operator expected
usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file target_file
cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file ... target_directory
Compilation error: Error: 2 UNKNOWN: exit status 64".

Back to esp32 by Espressif Systems V1.0.4, same thing again!

Aug. 21th 9:20PM: By the way, I've just installed ESP32 V2.0.0, from
https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html

What to do now?
Maybe I should migrate to VSCode...

@markyousif. This issue tracker is only to be used to submit detailed, formal bug reports and feature requests.

You need to ask for help on the Arduino Forum. I'm sure we'll be able to help you out over there:

Each actual cause of the generic "Error: 2 UNKNOWN" errors reported through this thread was completely unrelated to the others. The valuable feedback this issue ended up providing is that the current practice of exposing the users to internal details of the gRPC interface causes confusion and provides absolutely no benefit.

Even though the statuses have been made slightly more specific by arduino/arduino-cli#1251, in the end it's only a change from this:

Compilation error: Error: 2 UNKNOWN: exit status 1

to this:

Compilation error: Error: 13 INTERNAL: exit status 1

The "13 INTERNAL" doesn't add anything of value to the console output, and will likely even be misleading since "INTERNAL" implies something wrong within the IDE itself, so it's not really much of an improvement for the users over the mysterious "2 UNKNOWN".
