Raspberry Pi 32-bit

[acbtones]

Hi,

Firstly, thanks for the great software!
However, I can't get it to install on Raspberry Pi 32-bit OS.
Using a RPi 3, I installed 32bit OS ("Raspberry Pi OS Full (32-bit)") and tried the installation - log attached: 32bit_pygpsclient.log
Cryptography fails to install so the PyGPSClient install fails.
Is that related to this: pyca/cryptography#5766 (comment)
I think that's why previous discussions in this forum have suggested Rust is required.
Using the same RPi 3, I installed 64-bit OS ("Raspberry Pi OS (64-bit)") and tried the installation - log attached: 64bit_pygpsclient.log
Successful installation.

My wish is to add PyGPSClient to an existing 32-bit RPi installation running other software that will only run on 32-bit.

Also, when starting PyGPSClient, is it possible to start the stream immediately i.e. without clicking the USB button?

Thanks,

Anthony

The issue is as follows:

• PyGPSClient uses the pyspartn library, which in turn depends on the cryptography>=1.39 library to decrypt SPARTN messages.
• On most platforms, pip can install cryptography from a pre-compiled wheel (.whl) installation package.
• However, on some 32-bit Linux platforms (including Raspberry Pi OS 32 Lite or Full) the cryptography library is only available as a source code (.tar.gz) file, which means it has to be compiled by pip at installation time.
• This in turn requires:
  1. Rust compiler support (as some of cryptography is written in the Rust programming language). This is not installed as standard on most platforms. Specifically, it requires Rust compiler (rustc) version 1.56 or later.
  2. A handful of additional cryptography build dependencies, including libssl-dev and libffi-dev.
• At some point in the future, a wheel (.whl) installation package may be made available on 32-bit Linux platforms, but until then some additional installation steps are required, as described in the link below.
