AWS CRT binary not present in any of the following locations - Raspberry Pi 3B+

When I’m running the pub sub example as described below I get: The error I receive every time: (none of the solutions in #119 helped…

/home/pi/aws-iot-device-sdk-js-v2/node_modules/aws-crt/dist/native/binding.js:60

I have a Raspberry Pi 3B+:

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

VERSION_ID="10"

• Node: 14.15.3
• aws-iot-device-sdk-v2: 1.5.2
• aws-crt: 1.8.1

I tried the solutions here https://github.com/aws/aws-iot-device-sdk-js-v2/issues/119 but nothing helped.

I followed exact example as described in AWS IoT but still, this error occurs.

The commands I ran after trying the installed and updated in the following order:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install cmake
sudo apt-get install libssl-dev
sudo apt-get install -y nodejs
restarted by sudo shutdown -r 0
cd ~
npm install aws-crt
npm install aws-iot-device-sdk-v2
cd ~
git clone https://github.com/aws/aws-iot-device-sdk-js-v2.git
cd ~/aws-iot-device-sdk-js-v2
npm install
cd ~
mkdir certs
(I copied the certs and changed the name accordingly...)
cd ~/aws-iot-device-sdk-js-v2/samples/node/pub_sub
npm install
node dist/index.js --topic topic_1 --root-ca ~/certs/Amazon-root-CA-1.pem --cert ~/certs/device.pem.crt --key ~/certs/private.pem.key --endpoint <endpoint>
 (I swap the <endpoint> with my own....)

I can’t run the pub_sub example…

by the way the pythonv2 works, but I prefer using the node.js sdk…

We currently don’t include the pre-compiled binaries for raspberry pi, but you can do this manually if you want to.

Go here and follow the install instructions (I have also included them below)

git clone https://github.com/awslabs/aws-crt-nodejs.git
cd aws-crt-nodejs
git submodule update --init
npm install

Then you will want to copy the folder containing aws-crt-nodejs.node to the location mentioned in the error message:

cp -r ~/aws-crt-nodejs/dist/bin/linux-arm ~/aws-iot-device-sdk-js-v2/node_modules/aws-crt/dist/bin/linux-arm

You’ll likely need to install/build aws-crt manually and then point the sdk to your installation (or copy the installation into the SDK’s or application’s node_modules). We just added pre-built binary support for armv8/aarch64 (v1.8.5 of aws-crt, v1.5.5 of the sdk) but armv7a support is more difficult and I don’t know when it will get done.
