Synapse raspberry.

Unfortunately I don't have a spare RPI4 at the moment and they are hard to come by.
(And I just repurposed my last RPI3)

Note that RPI3 has a ARM CPU 64 bit.
I have installed Raspberry PI OS 64 bit on some of my RPI3 and fpc works ok, a few faster than on RPi OS 32 bit.

Yes, it does, but there are some Lazarus problems regarding GTK2 on RPi 4's. These are beginning to be sorted out.
Skip Wayland for the moment on RPi 4. Lazarus on RPi 4 using Wayland can give troubles.

Ha, ok ( I use a widgetset that directly uses Xlib (or XWayland) so I do not know those kind of problems ).

Hello.
I installed a new system and Lazarus 2.0.10 FPC 3.2.0 64 bit
I have installed component Lazserias and Indi .
Synapse via online packger manager cannot be installed.
Lazarus freezes.

Last week, I installed Ubuntu x64 on an RPI4 instead of RpiOS x64 because of its limitations and old packages.
Then I installed lubuntu-desktop and removed most gnome packages to make it lightweight.

On that system with lazarus-ide-qt and libqt5pas-dev, I was able to install synapse with OPM, and also, I built a complex program that uses synapse (synaser). - with QT5 widget set.

I've been trying to do this for a long time, so I finally replaced the raspbian buster with RasPi OS x64 (64-bit) and without any problems synapse installed via OPM and works.
I use Lazarus trunk and FPC fixes installed via fpcupdeluxe

[Thaddy]

Yes, I just updated one of my RPi 4 to test that and it works without the old hick-ups.
Reminder to self: update more often.

Note that I never experienced any problems with FPC, just Lazarus and that looks fixed with the RasPi AARCH64 OS update. (not x64: that refers to Intel)
