How do I verify my OS as 32 or 64 bits?

I need that to select NEW version of Eclipse, not the one which came with installing Raspbian ? bit system

  • Beware there is more to an ISA than address size. You don't just need a 32-bit package, you need a 32-bit ARM package. The regular x86 32-bit Eclipse will not work.

  • That depends on the OS. Presuming you are asking about Raspbian, the answer is in the second duplicate and implied by the first.

At the time of this writing, all officially supported operating systems are 32bit, and I'm not familiar with any unofficially supported 64bit builds that are particularly usable.

The command, uname –m will tell you what architecture your device runs on.

  • Close but no cigars None of the uname options , as far as I can tell, tells about the OS "bit structure".

    Once you've done uname -m head over here to find out whether it's 32 or 64 bit: unix.stackexchange.com/questions/136407/… My Pi 3 says armv7l which is 32 bit. Dec 11, 2017 at 14:58
