sous un renseignement je sais que je peux regarder le résultat de uname -m
savoir si mon système d'exploitation est en 32 ou 64 bits, mais sous ARM cela donne:
armv7l
J'ai déduit de
file /usr/bin/ls
que je suis sur un système d'exploitation 32 bits, mais comment puis-je le savoir plus facilement?
uname -a
et gcc -v
? Ceux-ci pourraient être utiles.
Announced October 2011, ARMv8-A (often called ARMv8 although not all variants are 64-bit such as ARMv8-R) represents a fundamental change to the ARM architecture. It adds a 64-bit architecture, named "AArch64", and a new "A64" instruction set. AArch64 provides user-space compatibility with ARMv7-A ISA, the 32-bit architecture, therein referred to as "AArch32" and the old 32-bit instruction set, now named "A32" ARM announced their Cortex-A53 and Cortex-A57 cores on 30 October 2012.
