Lazarus/Free Pascal running on a Raspberry Pi 4 :)

Try the Laz OpenGL examples.
There is some more in the fpc OpenGL packages.
Those FreeGLUT ones are fun.
So much stuff just works now.

Buster is easy, getting Laz/fpc on Pi4 Gentoo64 OS is bit harder.
The standard build stuff is too old for aarch64.
The binary version of 3.3.1 fpc works

I expect by the time fpc 3.2 is released it will all work.

I have it on the 3B+, and even tried it on the zero,
But the resolution I'm running the zero at, was too low (640pix) to comfortably display the gui.

Works fine on the 3B+ as well!

For the Zero use the text based IDE fp, is comes with fpc.
Laz is not needed for those fpc package examples either.

The PiCore TC Desktop is the only one I'm happy with on single core Pi's.

The zero W runs Raspbian full desktops pretty ok, with a slight optimization of the OS, and an overclock.
I do run it at 1024x600 pixels, or 720p, which allows me to run a GUI with 24-32MB of Vram. Freeing some RAM memory.
It does load a bit slow, and doesn't compile very fast, but most other things it does quite well.
It's more of a proof of concept that it can be done, on a $15 PC!

I doubt TC will make a big difference, as loading times don't change, and Raspbian desktop uses less than 1% of CPU to run.
The issue with tc is program compatibility. Finding up to date, good coding editors or IDEs on that is hard (if not web based).

Yep I pretty much settle for Geany as my stuff is pretty simple.
A thousand lines of code is a big app for me.

I am impressed with Thonny now on a Pi4, makes Python less painful.

Not sue why people like VS or Eclipse, to big and bloaty for me.

I have yet to try Buster on a single core, been spending lots of time learning how to use Pi4's as Desktop PC replacements.
C based coding normally uses lot of external dependencies
I don't need them so much with Laz/fpc as those comes with lots of libs installed as standard.

same with me

Lazarus and FPC runs fine on all versions of the Raspberry Pi.
I use a RPi4 and a Rpi3 as my main computer...
Refer to the Lazarus forum for advice if you run into any trouble:
https://forum.lazarus.freepascal.org/in ... tion=forum

Response times are usually quick, the Raspberry Pi is rather popular in the FreePascal community.

One note of advice: On anything except the Raspberry Pi 4/2GB+, increase the swap file to at least the same or double the amount of physical memory to be able to compile Lazarus or the compiler itself. If so you can even compile Lazarus and the compiler within a reasonable amount of time on any Raspberry Pi version.
