missing crt1.o / crti.o -lm

[Pe6r0]

Hey, great guide. Similar to others around but nicer I'd say.

Running into problems in the configure step. Any clue what's causing this? It's more or less a fresh build but I installed all the required packages. I have those files, but they are in /usr/lib32

sudo apt-get install libc0.1-dev

sudo apt-get install libc0.1-dev

I cant find that package. libc6-dev is already installed btw

To be honest, I got this going over a year ago for our QT app, (largely finding library files and throwing them in until it worked) but to quote the comment in the readme "the instructions that were written for an older version seem to become slightly broken with the new version".

Basically the work required to maintain a working QT build + Yocto on an RPi for little benefit, we are retiring our QT application and replacing it with a NodeJS front end for UI, and restructured our Python backend to have API end-points. I think grabbing a template web UI, using AI to help construct a front end, we spent similar time/energy to just getting QT app updated

My perception is that QT don't really seem invested into making sure this stuff works smoothly and not breaking things between releases, so I am done with it.

Not the answer I know people are looking for, but our solution

Thank you for your answer:)

For us that is not an option unfortunately. We already build our app with QT and cant just simply switch the 'engine'. Furthermore we do have a QT5 commercial license and therefore cant simply upgrade to QT6 either (setting up the CC for QT6 is waaaay less pain).
