Trying to setup MongoDB in Khadas board


I want to setup a mongo DB inside a Khadas VIM3 board, with Ubuntu 20.04. I want to implement MongoDB as the database for my C++ program.

Khadas boards have arm64 architecture

These are the steps I followed:

Installation of drivers

According to mongo’s official manual for mongo C++, I started installing drivers for C, then for cxx.

  1. I started by installing libmongoc driver

apt-get --no-install-recommends install libmongoc-dev

apt-get --no-install-recommends install cmake

I see this warning, judged it not critical (I am no expert, please don’t value my judgement :sweat_smile:):

/sbin/ldconfig.real: /lib/ is not a symbolic link

sudo apt-get --no-install-recommends install libssl-dev

sudo apt-get --no-install-recommends install libsas12-dev

mkdir downloads/installers

cd downloads/installers


tar xzf mongo-c-driver-1.24.4.tar.gz

cd mongo-c-driver-1.24.4

mkdir cmake-build

cd cmake-build


  1. My g++ is based in c++14, so I chose polyfill MNMLSTC, adding " -DBSONCXX_POLY_USE_MNMLSTC=1 " cmake option

I installed libmongocxx driver

  1. Executing “apt-cache policy libmongoc-dev”, I get “Installed: 1.16.1-1build2”. Given compatibility table, I go for mongocxx-3.5.x

curl -OL

tar -xzf mongo-cxx-driver-r3.5.1.tar.gz

cd mongo-cxx-driver-r3.5.1/build


As I’m using MNMLSTC

sudo cmake --build . --target EP_mnmlstc_core

Polyfill successfully installed, let’s build and install cxx driver:

cmake --build .

sudo cmake --build . --target install

I have all the logs from this, stored using ubuntu’s “script” command. I can provide them if necessary.

Thank you for taking your time to read and maybe help me, you are wonderful. Let’s keep going.

Installation of MongoDB 4.4



sudo apt-get install gnupg curl

echo “deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-4.4.gpg ] MongoDB Repositories focal/mongodb-org/4.4 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

sudo apt-get update

sudo apt-get install -y mongodb-org=4.4.24 mongodb-org-server=4.4.24 mongodb-org-shell=4.4.24 mongodb-org-mongos=4.4.24 mongodb-org-tools=4.4.24

echo “mongodb-org hold” | sudo dpkg --set-selections

echo “mongodb-org-server hold” | sudo dpkg --set-selections

echo “mongodb-org-shell hold” | sudo dpkg --set-selections

echo “mongodb-org-mongos hold” | sudo dpkg --set-selections

echo “mongodb-org-tools hold” | sudo dpkg --set-selections


No errors returned (appart from “/sbin/ldconfig.real: /lib/ is not a symbolic link” )

My system uses systemctl, so:


khadas@Khadas:~$ sudo systemctl status mongod

● mongod.service - MongoDB Database Server

Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)

Active: failed (Result: signal) since Thu 2023-09-14 09:50:34 UTC; 13s ago

Process: 8600 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=killed, signal=ILL)

Main PID: 8600 (code=killed, signal=ILL)

Sep 14 09:50:34 Khadas systemd[1]: Started MongoDB Database Server.

Sep 14 09:50:34 Khadas systemd[1]: mongod.service: Main process exited, code=killed, status=4/ILL

Sep 14 09:50:34 Khadas systemd[1]: mongod.service: Failed with result ‘signal’.


Configuration tweaks

I checked “ulimit -a”. It seems fine, but this is not a performance issue.

I see there’s no log file created, so I modify /etc/mongod.conf to raise log verbose. Still no log file created.

If you reached this point, I admire your effort. Thank you

May you have a great day.


Hi @MetolaEtra_N_A !
Welcome to the MongoDB community forums.

Thanks for the detailed steps. If I understand correctly, you are not able to run the MongoDB server that you installed. I see that call to start the mongod service is missing in your steps. Could you try executing it?

sudo systemctl start mongod

Hi @MetolaEtra_N_A

Welcome to the forums.

Check that this system is a supported platform, the ILL signal suggests that it does not.


MongoDB on arm64 requires the ARMv8.2-A or later microarchitecture.

Starting in MongoDB 5.0, mongod, mongos, and the legacy mongo shell no longer support arm64 platforms which do not meet this minimum microarchitecture requirement.

Thank you both for your answers.

Chris was on the right track, the problem was on the ARM microarchitecture.

Khadas VIM3 has: A311D big-little architecture. x4 2.2Ghz Cortex-A73 cores, paired with x2 1.8Ghz Cortex-A53 cores. (source)

MongoDB requieres ARMv8.2-A or later
ARM Cores Cortex-A73 and Cortex-A53 implement a lower ARM version, the ARMv8-A 64-bit instruction set (source A73, source A53)

Thus, MongoDB cannot run in Khadas VIM3.
