Re: [fpc-pascal] FreePascal and the OrangePi
When I installed fpc on my raspberry pi, I compiled from source, but that was when the pi was relatively new. I'm fairly certain there's a release for the pi. If the orange one has an arm processor, the release for the raspberry should work on the orange as well. On 10/21/2022 6:19 PM, Terry A. Haimann via fpc-pascal wrote: Dumb ?

Re: [fpc-pascal] MQTT package for freepascal/lazarus?
Hi, FWIW, I'm using MQTT via cmd-line. I.e. I call ExecuteProcess(MQTTExec,MQTTStrArr); while MQTTExec is /usr/bin/mosquitto_pub That's on a linux-server.

I could not find anything inside Lazarus' OnLinePackageManager. Is there something like that available? I made a front-end Pascal library, and and Object Pascal wrapper for libmosquitto a couple of years ago. It's available here. It's know to work on Linux, Windows and macOS at least. It's against libmosquitto 1.x. Not sure if 2.x got released meanwhile. I can update things if needed. (Pull requests are welcomed.) It's available here: https://github.com/chainq/mosquitto-p Well, the version of the mosquitto broker server that gets installed on my RaspberryPi4 is: $ mosquitto --version Error: Unknown option '--version'. mosquitto version 2.0.11 mosquitto is an MQTT v5.0/v3.1.1/v3.1 broker. So this is what I have to communicate with as a client. I need to be able to publish as well as subscribe to topics. In the Lazarus forum I have seen people having problems with this when they use various FPC packages while the native command line works OK (on Linux), probably because they are using old packages not updated for the changes made in MQTT in recent years. So this is why I am asking if there is some MQTT client package available for FPC/Lazarus that complies to the updated protocols? I found this on the Lazarus forum: https://forum.lazarus.freepascal.org/index.php/topic,54397.msg435050.html#msg435050 Not a poackage, but rather advice on how to utilize binary "drivers" installed on the system via translated header files. Not optimal, but might be doable anyway. I will try that path going forward, just now dealing with the MQTT source devices. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

It is controllable.
There is the 'Modulekind' : wkPooled.
Type
TWebModuleKind = (wkPooled, wkOneShot{, wkSession});
And a property of your module:
property Kind: TWebModuleKind read FWebModuleKind write FWebModuleKind default
wkPooled;
wkPooled is the default, but if you explicitly set this to 'wkPooled' in the constructor,
you'll be sure there is only ever 1 instance of the module, which is reused for
every request...
