I'm having an issue using the Teensy Audio library as part of a private libraries (under the lib folder of a PlatformIO project, as described in https://github.com/platformio/platform-atmelavr/blob/develop/examples/arduino-blink/lib/README).
I am developing some Teensy code that uses the Audio library, but I would like to eventually break parts of the codebase out into reusable libraries. For now, I'm developing them as private libraries under the `lib` directory. The problem is that whenever I import Audio.h, I get all sorts of compilation errors. In my main codebase, the first one is usually a "uint8_t does not name a type", but there's a series of undefined variable errors.
As a MWE, I've created two PlatformIO projects, one that imports Audio.h in the main.cpp file and one that has a private library that depends on it in the library.json file. The one that imports Audio.h in main.cpp compiles and it looks like:
main.cpp is
and platformio.ini is
The second MWE has a private lib that just requires the Audio library (defined in its library.json) and this fails to compile.
main.cpp is
and platformio.ini is
AudioTestLibrary.h is
and AudioTestLibrary.cpp is
Finally, library.json is
This project, with the Audio library as a dependency of the AudioTestLibrary does not compile. The compilation log re reads:
A couple of things to note:
I have published these two examples on Github in hopes that someone else trying them might be able to figure out what is going on here. The one that compiles (importing Audio.h in main.cpp) is at https://github.com/dkadish/TeensyAudioPlatformIO_main and the one that does not compile (with the audio library as a dependency for a private library) is at https://github.com/dkadish/TeensyAudioPlatformIO_library.
I'd appreciate any insight into what's going wrong!

* The terminal process "platformio 'run', '--verbose', '--environment', 'teensymm'" terminated with exit code: 1.
* Terminal will be reused by tasks, press any key to close it.A couple of things to note:
- I have tried this with different Teensy versions (teensymm, teensy40, teensy31) and the builds all fail in the same way, so it is not a MicroMod issue.
- I suspect the problem is that PlatformIO is missing some of the board-specific files/flags when compiling the private libraries, which is causing the problem here.
- I haven't tested this with proper PlatformIO libraries, so I'm not sure if this problem persists there.
I have published these two examples on Github in hopes that someone else trying them might be able to figure out what is going on here. The one that compiles (importing Audio.h in main.cpp) is at https://github.com/dkadish/TeensyAudioPlatformIO_main and the one that does not compile (with the audio library as a dependency for a private library) is at https://github.com/dkadish/TeensyAudioPlatformIO_library.
I'd appreciate any insight into what's going wrong!
