On the other hand, if you are not using our Docker Image, you will have to run
make menuconfig in the build system to select
libugpio package to be compiled and then compile it by running
In General you will need to have the external library, for instance
libugpio, to be compiled by the Build system before it can be dynamically linked to code that you are trying to cross compile. Above all, I strongly recommend basing your BUild system on our GitHub source repo since it is preconfigured to include the Onion software repo and to build all the libraries that are included on the Omega.
