I’ve set up exactly the same example as in the documentation for “lib_dir”:
“PlatformIO will find your libraries automatically, configure the preprocessor’s include paths and build them.”
No, it doesn’t. Neither the include files are found, nor the *.cpp files are compiled.
But “include_dir = …” works, then the include files are found and “src_dir” works as well, then the library files are found, but of course not “main.cpp”.
What’s wrong with my setup ?
Hope you can help

Additionally I’ve tried to change lib_ldf_mode to deep
all the parameters are simply ignored --> it can’t be that such a simply requirement doesn’t work ???
So you mean this example?
What main.cpp? The example references main.c.
Do you have your project uploaded to Github for reproduction of the problem? Or a more precise error message and project setup structure?
I have the same problem, when I set the lib_dir to specify my libraries, PlatformIO cannot find any header file in the libraries.
Are you sure you don’t want lib_deps or lib_extra_dirs?
Sure, I put the source code(.cpp and .h) in a directory named mylib, my project directory structure like this:
–mylib
----common
--------yCard.cpp
--------yCard.h
--------yFile.h
–src
----main.c
–platformio.ini
I config the option: lib_dir=mylib
Then I include mylib header file(#include “yCard.h”) in main.c,but it report error:no such file when i compile the project.
This is absolutely working.

Thank you for your reply！
Could you send me a copy of your experimental source code for reference
It was right there in the topic
Thank you very much!
