Lazarus Install PI5 Bookworm

[dbannon]

./myapp -disableaccurateframe can be used as workaround.

Thanks hansotten, useful info.

Fortunately, the more correct --disableaccurateframe also works. The gnu standard says single char options have one dash, multichar options should have two. In our case Application.CheckOptions() knows about only ShortOptions and LongOptions, no hybrids ! So, it will report the one dash version as an error, app should exit.

And interestingly, I can reproduce this problem (of the little window) only with gtk2, Qt5 works fine.

Hi All,

This is a shame, I was looking to start developing again in Pascal only to find out the one piece of kit I need to use has issues. The Pi5, I also get the small window. 

Lazarus is working fine on my desktop great.  But I need to develop a controller using the GPIO pins on the Pi.  Is there a simple work around (I'm trying to get back into development after 20 years out).  I also don't like the alternative of Python, this has a ton of issues.

Simplest workaround: Don't use Wayland.

Issue seems fixed in trunk but still Wayland is unstable. Please go bug/nag PiOS developers that they should either fix their shizz or stop distributing their OS with Wayland (as default). Wayland is not production ready.

Alternative: use qt widgetset which seems more stable on Wayland.

Yup, I've flipped the Pi to X11 I'll give this a go.

Feel free to inform whether or not you have better luck. Personally I got tired of checking 

Oh, and good luck (and welcome to the forums) !

Just a note: GPIOs are usable on a PC provided that you have an appropriate (usually USB-connected) addon board.

I summarised the situation at https://forum.lazarus.freepascal.org/index.php/topic,56063.msg416733.html but basically there are two rather (when I looked at it) poorly-defined APIs, and various things also depend on the facilities provided by the kernel module.

It's by no means perfect, but is a fair alternative to having an extra RPi (with all its issues) around if /all/ you need is GPIO (or for that matter I2C or SPI).
