Ha! That's an interesting use-case I never would have thought of 😎

Absolutely no output at all when doing make?

Hi, Thanks for the quick reply. Below is the output from running make on one of your tutorials. The copy towards the end fails because there is no kernel built for the make file to copy. The kernel.d file however is written out. I started out thinking the kernel was being built but put in some other place, but I now don't think that is so. As I said previously if I try this on my x64 Linux machine it all works fine. Regards Tim

Okay, so something is getting successfully compiled it seems. Maybe the name or path that the Makefile assumes differs.

Can you take a look into the target folder?

Hmm, strange... I don't have an explanation for that right now from the top of my head.

TimHutchinson commented on April 28, 2024

Me neither, but thanks for looking. I added the verbose flag to the xrustc command in the makefile but it didn't help. There is one thing I did different from your tutorial. I already had a Rust setup on my RPi4 so I just installed the nightly build and required components by hand and switched the cargo default toolchain. Maybe I missed something. I'll keep poking around. I have a spare SD card so I might go back and start again exactly following your curl script. (I did this on the x64 machine). I'll let you know if I find anything. BTW thank you for doing this project. Tim.

Hi Tim,

any updates on this? I think I would close this issue soon otherwise until further questions pop up.

Thanks,

Hi Andre, No joy I'm afraid. I tried various things including running everything as root in case it was some weird permissions problem. I even did a fresh install and exactly followed your instructions but still it would not build the kernel. Recently I installed a 64 bit version of Ubuntu on my Pi4 and tried to build your code there, but still the same problem it just silently fails. I think it might be an error in the linker as then maybe any error message is just getting thrown away by cargo. But that is just a guess I don't think I'm going to make any further progress.So will switch to using an x86 machine where it all seems to work ok. You can close the log. Thanks for your time. Regards Tim.

Alright, thanks for the update and sorry that I currently lack bandwidth to dig into that myself.

Best,
