I am running a Odroid with Ubuntu Mate. I need to download qt and so I need to know if I should get the 32 or 64 bit version of qt.

odroid@odroid:~/software/qt5$ uname -i
armv7l

uname -i returns armv7l. Does that mean I should download the 32 or 64 bit of qt?

armv7l is 32 bit processor.

If you need a little bit more information regarding ARMv8, please read @Rinzwind's answer :-)

ARMv8 is 64-bit. With 32-bit compatibility.

The ARMv8 architecture introduces 64-bit support to the ARM architecture with a focus on power-efficient implementation while maintaining compatibility with existing 32-bit software. By adopting a clean approach ARMv8-A processors extend the performance range available while maintaining the low power consumption characteristics of the ARM processors that will power tomorrow's most innovative and efficient devices. ARM has 3 different product tiers supporting the ARMv8-A architecture: High Performance, High Efficiency, and Ultra-High Efficiency.

---

ARMv8-A introduces 64-bit architecture support to the ARM architecture and includes:

• 64-bit general purpose registers, SP (stack pointer) and PC (program counter)


• 64-bit data processing and extended virtual addressing

Two main execution states:

• AArch64 - The 64-bit execution state including exception model, memory -model, programmers' model and instruction set support for that state


• AArch32 - The 32-bit execution state including exception model, memory model, programmers' model and instruction set support for that state

---

Anything lower (like ARMv7) is 32-bit.

  OP asks specifically about ARMv7 and you fill half a page about v8 just to mention in your last sentence that v7 is always 32 bit? I mean, it's correct of course, but... you know
