Can't Compile because of Library Update?

[Proktologe]

The new Version is: BSEC_2.0.6.1_Generic_Release_corrected_05092022 but your Compile Scripts is looking for:
BSEC_2.0.6.1_Generic_Release_04302021

I tried to change the Name of my current downloaded file to your version but this gives me the following error result (in terminal after enter sudo python3 setup.py install):

I saw the same issue in that Bosch have issued an update that has the following directory name: BSEC_2.0.6.1_Generic_Release_corrected_05092022. My sd-card failed and I rebuilt a new card last week. I renamed the folder to match the old release name BSEC_2.0.6.1_Generic_Release_04302021 and it built succesfully with the usual warnings.
You did built yours as root or with sudo?

I looked for your missing file and in my system (raspbian bullseye) it is a symbolic link to gcc10: /usr/bin/arm-linux-gnueabihf-gcc -> gcc-10

Hope this helps

Are you running a PI 4 and 64 bit OS?

Are you running a PI 4 and 64 bit OS?

No, Raspberry Pi OS 32 Bit, on a Pi 400

[mcalisterkm]

OK So the PI 400 is a 4GB PI4 overclocked with a large heatsink in a keyboard shell. I just checked and my PI 4's are running Buster. Here is a succesful build on a 32 bit buster PI4 with 4GB. I use FileZilla to copy the PI3G 1.3 code from April 2022 (v1.3) and the latest Bosch release BSEC_2.0.6.1_Generic_Release_corrected_05092022 to the PI.

Check your version of the PI OS matches

I run $sudo su - to get root as.

Your folder should look like this:

Here is the first error due to the BSEC release name change

Correct the folder name as follows

root@PI4-3:/home/pi/bme68x-python-library-main# mv BSEC_2.0.6.1_Generic_Release_corrected_05092022 BSEC_2.0.6.1_Generic_Release_04302021

If you can't get this start with a clean raspbian install, and work from that.

I used pip3 to uninstall , copied in the new library 2.2.0.0 then renamed it and built it using python3 setup.py install and it works. Perhaps that is not a clean enough build to see your issues.

[mcalisterkm]

I have cleaned up and built from scratch and I see the two errors mentioned: bme68xmodule.c:388:52: error: ‘BSEC_SAMPLE_RATE_HIGH_PERFORMANCE’ undeclared bme68xmodule.c:1069:42: error: ‘BSEC_OUTPUT_COMPENSATED_GAS’ undeclared

These are due to changes in the BOSCH header bsec_datatypes.h a) BOSCH have renamed BSEC_SAMPLE_RATE_HIGH_PERFORMANCE’ to BSEC_SAMPLE_RATE_SCAN b) BOSCH have deleted BSEC_OUTPUT_COMPENSATED_GAS from the enumerated list of virtual sensors.

The changes BOSCH have made at BSEC 2.2.0 breaks bme68x v 1.3, and I think we need a new version of bme68x to support BSEC 2.2.0.
