Adding compression libraries to Zephyr

[JPSvanderWalt]

Hi, I want to add compression libraries like lz4 and audio compression to my zephyr projects.  I am struggling to find good guides on how to add external/third party libraries to Zephyr.  Can anyone point me to a guide on how to include libraries in the Zephyr project?

Check out the example external_lib, which demonstrates how to go about this.

The section 2.2.1 Include header and source files to your project might be useful as well.

Best regards,

Simon

Thank you will take a look.  Will this also help if the library is hosted on github?

[Simon]

If you want to fetch a library directly from GitHub, you could add the library to the west.yml file, such that it will get fetched when running west update. You could either create your own fork of the nrf repo and put it into your modified nrf/west.yml or you could create your own west.yml file in the application (Check out https://github.com/OeySa/nRF9160-Hello_Board). Check out Adding your own code for more detailed explanations.

Best regards,

Simon
