PPPoS modem library
Posted: Mon Oct 14, 2019 10:05 pm
Hi,
I need to use the PPPoS API from ESP-IDF, so I've tried the pppos_example code (with some modifications) and managed to make it work as I wanted for my application.
The problem is that when I tried to add it to my main project the program simply won't compile, and i have the next output:
I don't know why it says that some functions are "undeclared" or "undefined" when that's the point of using libraries.
Is this some problem with the compiler? I have the same CMake files as the pppos_example project.
Does someone has any idea?
Thanks,
P
