Correct organization and linking of multiple cpp and h files

Correct, .c/.cpp files in include/ are not compiled ("added to the build system to produce a .o object file that will be linked in the final .elf). If foo.h is in include/, this is correct. Libraries by default don’t see the files in include/ without the user explicitly adding build_flags = -Iinclude/ in the platformio.ini. If lib/bar/* depends on a foo.h file, then foo.h should either be in a library (so that the LDF can detect a dependency to it and include it), or if that file truly belon…

Include header from include dir into lib dir

It turns out apparently I had two problems, one was about include the global header file, and the other was the library dependency finder configuration. By adding both lines to my platformio.ini everything compiled nicely: build_flags = -Iinclude lib_ldf_mode = chain+ I found this solution better than setting this configurations in a library.json file because my project is going to have several private libs, so instead of having this duplicated in every private lib, I’d rather have one global …
