Hi! I’m adding mavlink library (GitHub - mavlink/c_library_v2: Official reference C / C++ library for the v2 protocol) from library toolbar inside vscode. But I have an error on a mavlink.h header file like it is missing.
Funny, same topic as in Include library in main.cpp - #2 by maxg
The library really doesn’t conform to the PlatformIO library structure at all and it doesn’t have a manifest (library.json) to tell PlatformIO its include paths, so… weird things happen.
Also the mavlink.h file exists 12 times in that library, what’s up with that?

If you don’t want to change the #include name, you can add the right build path to your build flags in the platformio.ini.
build_flags =
-I"$PROJECT_LIBDEPS_DIR/$PIOENV/MAVLink v2 C library/standard"
Replace standard with the folder right folder out of the 12 possible

As always, thank you for your reply.
The way I understand it, by pointing to or including the mavlink.h file in the respective folder, a specific subset of MAVlink commands will become available.
kinda tricky to release a library in platformio not being built for platformio. Thanx, your build_flags advice worked!
