Hello!
I installed the program successfully, but when I try to start any scatch, I receive the message:
avr-g++: error: C:\Users??????\AppData\Local\Temp\arduino\sketches\2E41EBFA4E6E2ECC08909F56A5B3C067\sketch\Project_1_Push_Button_Control_LED.ino.cpp: Invalid argument
avr-g++: warning: '-x c++' after last input file has no effect
avr-g++: error: device-specs/specs-atmega328p: No such file or directory
Hi @solot. I'm going to ask you to post some additional information that might help us to identify the problem.
NOTE: These instructions will not solve the problem. They are only intended to gather more information about the problem.
Please do this:
Select File > Preferences... from the Arduino IDE menus.
The "Preferences" dialog will open.
Check the box next to "Show verbose output during: ☐ compilation" in the "Preferences" dialog.
Click the OK button.
Select Sketch > Verify/Compile from the Arduino IDE menus.
Wait for the compilation to fail.
You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the COPY ERROR MESSAGES button on that notification.
Open a forum reply here by clicking the Reply button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the compilation output into the code block.
Move the cursor outside of the code tags before you add any additional text to your reply.
Click the Reply button to post the output.
In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here:
Open a forum reply here by clicking the Reply button.
Click the "Upload" icon () on the post composer toolbar:
A dialog will open.
In the dialog, select the .txt file you saved.
Click the Open button.
Click the Reply button to publish the post.
Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.
