Running F' on the Raspberry Pi 5

[kadeangell]

Hey! I'm just trying to follow the Hello World tutorial on the Raspberry Pi 5, but I get an error when I try to generate the build cache.

This is the output I get:

(fprime-venv) kade@raspberrypi:~/MyProject $ fprime-util generate

This error occurs when you have not installed the python tooling.

pip install -r "/home/kade/MyProject/fprime/requirements.txt should fix the issue.

Our build server reports:

getconf PAGESIZE
4096

A page alignment issue.....this should be reported as an issue to FPP and we can fix it in the next release.

[kadeangell]

Okay. Should I go create an issue in the FPP repo? And will this cause an issue if I try and cross-compile using aarch64 and run the compiled binary on the Pi?

[LeStarch]

I can make the issue, as I have lots of context to add to it. Cross-compiling should be unaffected (unless you are running on an aarch64 cross-compiling host with a kernel page size greater than 4096.

[LeStarch]

You did already! I'll add context to that one.

[kadeangell]

I did! sorry, wasn't sure what to do when you didn't respond for a bit.

[LeStarch]

No worries at all, the same result was reached! Thanks for looking into this!

I'm experiencing a related issue while using my newer Macbook which has Apple silicon. After circling back on the same error of "-- [fpp-tools] fpp-depend installed incorrectly" when trying to run the fprime-util generate command, I realized these newer chips run an ARM architecture whereas the F' requires Intel x86.

I executed the command you gave above and saw this error:
fpp-depend --help
zsh: bad CPU type in executable: fpp-depend

I ended up having to install Rosetta 2 from my terminal to run the x86 code on the ARM architecture. Hope that helps someone who might be experiencing a similar issue.

@bocchino or @Kronos3 might know more about this. Do you support/plan to support ARM executables for the fpp toolchain?

[LeStarch]

The current formal release of the FPP tools requires Rosetta 2 on Mac hardware. (aarch64, Intel are supported on Linux).

We have a fix for native mac w/ aarch64 support and expect it to come in the next release.
