Error building mongo 4.2.12 on debian 10 arm64

I am trying to build mongo on Debian 10 arm64. I am trying to use the official documentation to build but it's failing every time. I am just building mongod using the command:
python3 buildscripts/scons.py mongod
This results in the following error:
Compiling build/opt/mongo/db/logical_clock.o
g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.
scons: *** [build/opt/mongo/transport/message_compressor_options_server_gen.o] Error 1
scons: building terminated because of errors.
build/opt/mongo/transport/message_compressor_options_server_gen.o failed: Error 1
Previous build try resulted in:
**g++:** **fatal error:** Killed signal terminated program cc1plus
compilation terminated.
scons: *** [build/opt/mongo/db/db.o] Error 1
scons: building terminated because of errors.
build/opt/mongo/db/db.o failed: Error 1
Online search suggested that I might be using the wrong tool chain:

I'm new with Android Studio, and I'm just trying to run the sample code automatically generated for a Flutter project, but I'm having issues while trying to run the build. Here is the error I get on the console:

Fatal error: Uncaught CurlException: 7 in base_Facebook.php on line 967

I just follow same code from here
I'm getting this error frequently today. I've googled it but couldn't figure out exactly what's the root of the problem. Could be my host? Could be Facebook?
