Linking static libraries with Particle Workbench

benjenkins · June 20, 2021, 11:22pm

Hi,

I am trying to use the Bosch BSEC library and the e-series device for an IOT project. The BSEC library is closed source and requires a static library to be linked during the compile. Does anybody have experience with this.

https://www.bosch-sensortec.com/media/boschsensortec/downloads/software/bme688_development_software/bsec_2-0-6-1_generic_release_04302021.zip

I have noted several previous attempts of people trying to do this, and I have tried following the steps on their posts, with no success.

https://community.particle.io/t/use-bosch-bme680-bsec-arduino-library-in-particle-workbench/52517

https://community.particle.io/t/bsec-sensor-library/41166

I am running Particle Workbench v1.13.8
E-series OS version 2.0.0

The errors I get are;

Executing task in folder hivesense: make -f 'C:\Users\Ben\.particle\toolchains\buildscripts\1.10.0\Makefile' compile-user -s <

Press any key to close the terminal.

I have made a build.mk file as suggested in one of the posts. Its contents is;

My Particle Workbench file structure is;

From what I can gather the libalgobsec.a is not being linked and therefore the error message undefined reference to bsec_get_version’`

Any help would be muchly appreciated.
Cheers,
Ben.

Hi.

Does anyone know if particle offers a consultancy service? Still haven’t had any luck with this issue. Has the potential to be a show stopper.

Any help or advice would be greatly appreciated.

Cheers.

Ben.
