BSEC 2.4.0.0 errors when installing BME68x library for Python

[fabioCarfi95]

I'm trying to install bme68x on 64-bit architecture Raspberry Pi 4.

I tryied to use the BSEC 2.4.0.0 downloaded from your webpage and I followed all the steps explained in this repository but I get some errors when launching the setup.py installation. Following the screenshot of the error I get

Can you help me?

Hi fabioCarfi95,

Could we know your host architecture for your Raspberry Pi 4? If it is ARMV8 architecture, you should use the library "BSEC2.4.0.0_Generic_Release_23012023\algo\normal_version\bin\RaspberryPi\PiFour_Armv8\libalgobsec.a".

[fabioCarfi95]

The host architecture is an aarch64.

Using the uname -a  CLI command I get this: "linux ubuntu 5.4.0-1089-raspi #100-Ubuntu SMP PREEMPT ... aarch64 aarch64 aarch64 GNU/Linux"

I also tryied changing the the directory to PiFour_Armv8, as you suggested, but I get this errors:

What is it about?

[kmca]

In this instance the PI is running a 64 bit OS, and the BSEC library although it includes an ARM V8 directory it is a 32bit library that is provided.  There are various approaches to running 32 bit code on 64 bit linux , but add in the Python 32/64 and the PI3G C wrapper and you could waste a lot of time trying.  

My question for BSTRobin is will BOSCH Sensortec be creating a 64bit BSEC library for the  PI as the 64bit OS is becoming a more popular choice.

Hi fabioCarfi95,

The host architecture is the core of MPU, not compiler information.
In addtion, we would like to know your compiler information. You can run "aarch64-linux-gnu-gcc -v" command to display your compiler information.

Hi fabioCarfi95,kmca,

There is already a 64 bit Linux BSEC library libalgobsec.a in the BSEC directory "BSEC2.4.0.0_Generic_Release_23012023\algo\normal_version\bin\gcc\Linux\m64", and I am not sure if this is what you need, so I need you to provide detailed information on the host architecture and compiler information.
