Uno R3, or Nano Every? They're not at all the same thing.

rajasekharemb080 · November 1, 2024, 5:42am

ARDUNIO UNO

UNO

van_der_decken · November 1, 2024, 5:43am

Then where is this line coming from?

rajasekharemb080 · November 1, 2024, 5:44am

uno

EVEN example programs are also not working i have uninstalled it and install it but same error

cattledog · November 1, 2024, 6:07am

What is "it"?

rajasekharemb080 · November 1, 2024, 6:12am

i have uninstalled the arduino ide and install it but same error is repeated

sterretje · November 1, 2024, 6:14am

This is possibly a caching error. See if the following will solve it:

Close the IDE.
Delete the directories in C:\Users\rajas\AppData\Local\Temp\arduino.
Delete the directory C:\Users\rajas\AppData\Roaming\arduino-ide.
Start the IDE.

The directories will be recreated; in case of doubt, make a backup.

But you left some of the stuff

Your topic was moved to the dedicated IDE 2.x category of the forum; the output that you provided indicates the use of IDE 2.x, not of IDE 1.x.

i hve tried it but same error

Using library manager in the IDE
- Uninstall the megaAVR board package if it is installed.
- Downgrade the AVR board package to 1.8.3.
Compile for Uno. If it works
- Upgrade the AVR board package to 1.8.6.
Compile again for the Uno. If it works
- Install the megaAVR board package again if you need it or for testing.
Compile again for the Uno.

You might have to uninstall more board packages.

If you want to do a full uninstall, you can find involved directories here: Uninstall/Fresh Install of Arduino IDE - #4 by ptillisch. Close and uninstall the IDE and next remove all directories except the sketchbook directory.

no change i have uninstalled it and installed it by using the following steps you have mentioned by i am getting the same error

rajasekharemb080 · November 1, 2024, 7:26am

OK, in that case I think that a full uninstall is advisable. See steps that I provided and the full topic that I linked.

rajasekharemb080 · November 1, 2024, 7:29am

i have don the same thing full uninstall

rajasekharemb080 · November 1, 2024, 7:37am

ok it is working when i change the AVR board package to 1.6.20

sterretje · November 1, 2024, 8:23am

I did find this but I would have expected that that was solved by now: lto-wrapper.exe: fatal error - #5 by pert.

I suspect that something "stinks" in your installation. There would have been thousands of users complaining if this was the current state of affairs and everybody had to roll back.

Is there anything special on your system; do you use other IDEs as well that might modify the ld.exe? Can you run the below command from a command prompt (for the AVR 1.8.6)

c:/users/rajas/appdata/local/arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/../lib/gcc/avr/7.3.0/../../../../avr/bin/ld.exe --version

The output on my system

If your problem does not happen when you compile blink, can you post your sketch? Please provide links to any 3rd party libraries that you use.

Below is the linker command (IDE 2.3.3, AVR 1.8.6) on my system

There are no /../ in the directory path and no use of ld.exe; it makes my feeling stronger that something is wrong with your system.
