Hi I am bulding a Dashboard appliacion where i want to integrate the maps Using the General magic plugin. When i am running the applicaiton on my Desktop its running perfectly but when i try to run the same in my Raspberry Pi its showing the following memory allocation issue both my Desktop and Raspberr Pi has 8gb of ram.

QT version : 5.15.2
Raspberry PI OS : Raspberrypi os
Raspberry Pi SD Card : 64gb
Desktop OS : Ubuntu OS

My Code :

@Gautham0517 said in Memory allocation Issue in Raspberry pi 4b 8GB Ram:

GEM: F/E May 01 02:24:08.671 <Platform>gp::MemMgr::AllocFail Out of memory allocating

The Raspberry is out of memory, I'd say.
