arduino 64

Hello, I've just tested the new 64bit app but it tells me:

hardware/tools/avrdude: error while loading shared libraries: libusb-0.1.so.4: wrong ELF class: ELFCLASS64

avrdude is in the arduino dyrectory, so i think it's a bug.

:slight_smile:

Maybe something like this is what you are attempting?

Do you have a 64 bit AMD running linux?

Your link talks about how to install the arduino enviorment version 10. Version 10 don't supports amd64. I've downloaded version 12 that officially supports amd64 machines but it doesn't works!
I've an AMD64 ArchLinux machine.

Ok, I think I understand now. You might have to be more descriptive though. What were you testing at the time? How did you install it?

Ok, sorry.
I've extracted the archive and I've runned the application.
I can write the code and I can see the tty periferics but when I upload code on my Arduino I see the error message.
Some time ago I've tried to install older versions but they cannot make conflicts because the Arduino Enviorment uses it's own libraries, isin't it?
It's important to know that ArchLinux isn't a multilib system.
