[SOLVED] Compilation error

Development Tools IDE 1.x
1

Arduino 1.8.19, Windows 10, Arduino Nano.

Hi, I get the following error when I click verify or upload

CreateFile C:\Users\Dell\AppData\Local\Temp\arduino_build_689334: The system cannot find the file specified.

Error compiling for board Arduino Nano.

This happens after every single successful verify or upload.

Restarting the IDE fixes it for a single verify/upload only.

Uninstalling and reinstalling the IDE has not fixed this.

I hope that makes sense, any pointers appreciated.

Thank you
Andy.

Post the complete error and use the <CODE> button to put it all in a "terminal" font.

What board are you using? Looks like Nano clone. Are you using the CLI or the GUI?

Are you signed-in to Dropbox? Try moving the folder locally.

5

Use verbose option. Make sure you save sketch before verify or upload.

6

Yea, its a clone.
Tried with an OEM Micro with the same result.
Signed out of Dropbox, working on local folders.

7

Verbose in checked under prefs, sketch is fresh after every UI restart.
Using GUI.

8

The error says it is trying to find the Dropbox file. You will need to fix that.

9

Where does it say it cannot find the source file?
Following initial compilation and upload [successful], it seems to lose the temporary file created during compile time during subsequent attempts.
Unless I'm reading it wrong or my understanding is amiss?

I think I need to monitor the temp file directory to see if the files are being cleaned up following compilation & upload.

10

Do a save before a compile or upload

11

Just to clarify, I load a sketch I don't change, I have to save it again before upload?
Something to do with attributes?

12

The arduino_cache_xxxxxx and arduino_build folders disappear after successful upload.
Folder C:\Users\Dell\AppData\Local\Temp\

Looks like a windows storage management issue unless something within the arduino ide [gui] does this ?

13

If no change not normally needed, but with Dropbox all bets are off. I encounter these types of issues frequently. Witojut a long winded explainer, temporary files are involved and somehow they get messed up when non local file storage is used. I use Windows cloud called OneDrive but I have all files forced to be local so my real sketch is always where you expect it to be (on my SSD) BUT the temp files I have no 'local' option for so they cause a problem unless I force a save.

14

Probably in the error.

15

Thank you.

16

I have "save on compile and upload' checked in prefs.
My G-drive is local with a folder called dropbox but the dropbox app is not enabled [no active synchronizing].
It's still the same.

However...
Folders in the temp directory are removed after initial upload and are therefore missing the next time I verify or upload, hence the error.

Thank you anyway.

17

That sounds familiar, what version of IDE are you using?

18

1.8.19

19

It was an issue in Ver2.x so I don't know.

Thank you anyway.
