Last version that can be installed (in a reasonable time) on raspberry pi zero W is 1.5.0

Theengs gateway
1

TL;DR :rocket: As of now, installation of the present version of TheengsGateway on a raspberry pi 0 w (bookworm, 32bit), takes several hours (I do not exactly know how many, more than 3 for sure). By installing some older pip modules, version 1.5.0 can be installed within minutes. This information may be useful for other Pi 0 w users.

I have been using TheengsGateway on several raspberry pi (3b, 4 and 0W) since version 1.2.0 without any problem. I have now updated the OS and installed the last version (1.6.0) on the raspberry pi 3b with bookworm 64bit without any problem.
When I tried to do the same on my pi 0W, with bookworm 32bit I had to stop installation after three hours. Pip was compiling Cmake from sources.
The version of cmake available in bookworm with apt is 3.25.1-1 which apparently is too old. On the raspberry pi 3b the compilation of cmake did not take so long.

I therefore tried to step back to a Theegsgateway version not requiring the new cmake. It was not only matter of requiring the older version of TG but also of some other modules. By trial and error I managed to install version 1.5.0 by manually installing first

  • pip install dbus_fast==1.83.0
  • pip install pycryptodomex==3.18.0
  • pip install TheengsDecoder==1.7.8
  • pip install TheengsGateway==1.5.0

Is there any better workaround? Should I let the pi 0W compile the wheel for all the required time?
Thank you for your attention

Try to install Theengs decoder first with the instructions below:

And after install Theengs gateway

Thanks for your answer. I am on freshly installed bookworm on raspberry pi0w. I tried following instructions but when I installed

pip3 install setuptools setuptools_scm cmake==3.25.0 wheel scikit-build ninja

The installation was stuck compiling cmake-4.1.0.

I tried again, by installing one package at a time. The culprit is the ninja package.

Maybe the 32bit image for raspberry pi zero w is not complete for some reason?
