Cannot find Online Package manager in V4.4 on RPi

[Flea]

Hi, I have been using the fpcupdeluxe tool on the latest version of Raspberry Pi OS. Its version is 13.2 (trixie) which I believe has significantly changed under the hood in terms of front end. I've installed FPC 3.2.3 and Lazarus 4.4 (stable) and a few other versions.

I cannot for the life of me find Online Package Manager (OPM), normally under the 'Package' IDE menu in previous versions of Lazarus. On the Windows version that I have installed with the same version of Lazarus, OPM is there.

Any ideas? TIA.

For some reason, the OPM is not installed on your system. In order to install it go to "Package" > "Install/uninstall packages" > find the entry "Online package manager" in the right list ("Available for installation") > select it > click "Install selection" > then "rebuild IDE". After a while the IDE restarts and you should have the "Online package manager ..." item in the "Package" menu.

Thanks wp ! That fixed it in all my versions that I installed. How weird that it was not installed by default.

How did you install Lazarus?
Did you use FpcUpDeluxe?

Yes, as per initial message in the thread, I used the fpcupdeluxe. Ive actually got my app compiling on a few version of Laz now using fpcupdeluxe :-)

Sorry, I missed that you said you used fpcupdeluxe.
I think that fpcupdeluxe doesn't install OPM by default.

I was not able to compile 4.4 on a fresh Raspbian Trixie. Or recompile the IDE after installing Lazarus 4.4 with the *.deb from Source Forge.
This is the error message after rebuildung IDE

You need to enable x11: trixie is wayland by default. You can also compile Lazarus for Qt6 instead of GTK2.
That is actually the better option since GTK2 itself is deprecated, although it is still the default in Lazarus.
Qt6 works fine on Lazarus + trixie.
