Can I build for x86_64 on an arm64 device?

Just a question, can I build for x86_64 on an arm64 device?

Sadly, no (at least, logically). x86-64 and arm64 are two radically different architectures. It's roughly the same as asking a fish to climb a tree, and asking a squirrel to go diving.

Cross-compilation should work fine, that's a big part of what buildroot does. Just as we can build images targeting the RPi on x86, you should be able to build for x86 from an ARM host.

I'm closing this because I just enabled the "Discussions" tab so people can ask questions there instead of opening issues.

Edit: I migrated it to the "Discussions" tab, didn't know you could do that. This is the first time I've enabled Discussions on one of my repos :^)

@joshiemoore Well, I tried compiling for x86_64 on my Raspberry Pi 4 machine, but in over 12 hours I didn't get an ISO. The terminal just hanged. And I re-cloned it so I don't know.

I would think that attempting a full snakeware build on an RPi host could take like a day or more, I wouldn't recommend using an RPi as your dev environment for this.

https://elinux.org/Raspberry_Pi_Kernel_Compilation

The "Overview" section of this page says that compiling a kernel on an RPi took them 12.5 hours, and snakeware builds a lot more than just the Linux kernel.

Legit just saw this. Might try doing it in a VM.
