Synapse raspberry.

[Mi-Ki]

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.

Raspberry 64 is not a normal target (yet). So problems can arise. But Lazarus is not freezing normal. You can start Lazarus from commandline and look if a message appears.
But Synapse is not a component to install in Lazarus. It must only be known by Lazarus, NOT INSTALLED. You can open the downloaded package from OPM and make a compile of the package (Not Lazarus). There can be some errors due the 'special' target.

It's too sad that there is no synapse for 64 bit Lazarus.

That does not matter too much, since fcl-web is just as good and syntactically very close to synapse. I have ported almost all my synapse  code that need not be portable with delphi to fcl-web.

I can't find the FCL-Web component.
Where can I find?

This is not correct, but nobody have testet it before, but you can look, whats going on :-) Often only the correct defines are missing.

Are you sure that synapse is causing the issue, because it's a runtime package. Can you create a backtrace(https://wiki.freepascal.org/Creating_a_Backtrace_with_GDB)? Alternatively build a debug ide and run Lazarus inside Lazarus. Don't forget that is always a lazarus_old executable inside the lazarus folder, so you don't have to reinstall Lazarus it if something goes wrong, just replace the binaries.

@GetMem
There is/was an issue with Synapse. I provided a patch somewhere, dunno if it got applied.
Anyway: MY synapse works on my RPi's, but as I said, fcl-web is much the same and I prefer it.
(matter of taste, not of quality)

@Thaddy
OPM has the latest version of synapse trunk r. 267 from 2023.02.09 (just checked), so most likely your patch wasn't applied.

Was that an issue that could cause Lazarus to freeze?

I don't think the freezing of Lazarus IDE on RPI has anything to do with Synapse.

Synapse works just fine on Lazarus 64 bit.

The issue was that a certain const structure syntax differed between Delphi and FPC.

Have you test it with Intel or ARM ? RasPi 4 is a ARM system. As i know this is a new Target, not often used yet

Linux on Intel 32 and 64 bit and ARM 32 bit.
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)

But like you said yourself, a freezing Lazarus shouldn't be because of Synapse.
So there must be something else wrong.
(And TS said Indy was installed just before so my guess is that's the culprit  )

It is probably more used as an OS than FreePascal and Lazarus are used as a compiler suite on an AARM64/Raspberry Pi.
The 64 bit OS certainly needs polishing, but both FPC and Lazarus work. (Although I compile by hand, it should be OK with fpcupdeluxe)

It is about the AARCH64 architecture, not Intel...
On AARCH64/RPi, Synapse needs a patch.
Not a difficult one for you and me and some others, but still it needs to address some oversights in Synapse 4.2/4.1. You will know it when you hit it.
