Problem library missing

Hi all!

Trying the basic input sample on my RPI, I get the following error message :
The package “” does not exist. You might be missing a library.

Platform RPI model 3B+
Raspbian GNU/Linux 11 (bullseye)
Processing 4.0.1

Thanks foe your help !

If you start the program ‘Processing’ then you will see the menu with ‘Tools’.

If you click on ‘Tools’ and then on ‘Manage Tools…’ you will see the window ‘Contribution Manager’ and the following five departments; Libraries, Modes, Tools, Examples and Updates. Choose for the department Libraries and inside Libraries choose for ‘Hardware I/O…’.

That’s all…

Good luck,

yes, the library was already installed.
Since the 64bits linux os for Rpi, there is a mismatch in the folders where the processingio library is stored.
before folder was linux-armv6hf and now is linux-arm32
And thus there is a bug in the exportApplication. I can achieve the problem if i change the folder name.
