Issue description

pip3 install pyzmq==22.0.3or pip3 install pyzmq does not install this package anymore on imx6ul based single board computer

Environment

Hardware: NXP imx6ul (https://www.phytec.com/product/phycore-imx6ul/)

Minimal test code / Steps to reproduce the issue

  1. Not required. This is Installation error. NOTE: On desktop distros, installation is still fine. NOTE: This problem occurred only yesterday. All the previous days it was installing fine.

What's the actual result? (include assertion message & call stack if applicable)

  1. Attached all possible trials pyzmqerror.txt
  2. Removed other packages which are required for our application (python-string-utils jsonschema websockets websocket-client schedule aiofiles ocpp) and tried installing only pyzmq. Did not work.
  3. Mostly tried solutions provided by ChatGPT.

What's the expected result?

I know that this particular hardware will be unavailable for you to test. Please take help of logs and let me know.

Thanks!

First, always make sure pip is up-to-date (pip install --upgrade pip and show pip --version).

Second, when it compiles from source, it suggests you have no compiler:

error: command 'arm-phytec-linux-gnueabi-g++' failed: No such file or directory

You need whatever the appropriate Python Extension build dependencies are for your system (e.g. python3-dev on debian/ubuntu). This should be generic, for any Python extension, not specific to pyzmq.

thanks for the suggestion. cross compilation was the only method to solve this issue. we had to include the package like this in the following file: yocto/build/local.conf IMAGE_INSTALL_append = " python3-pyzmq".

"arm-phytec-linux-gnueabi-g++" was available in the yocto toolchain and was not in the compiled image due to size constraints. whole OS is around 180MB.
