Do you have libmbedtls installed? If so, you may need to adjust the C_LIBRARY_PATH and eventually LD_LIBRARY_PATH.

[Synss]

Have you had any luck after copying the headers on the Pi or with C_LIBRARY_PATH?

I do not own a RPi and will not be able to help you packaging there. You may have better luck on stack overflow, the RPi forums or mailing lists. python-mbedtls is more or less compiled like a C library.

I did not install libmbedtls, but I can't say that its not already there in the Pi. I didn't try to copy headers. Not sure how to do this. I decided to use the pyca/cryptography library instead, which uses openssl. This worked on both Windows and Linux (Pi). I'm not planning to pursue this issue, but it remains an issue for others that might want to use mbed tls on a Pi with Python.

Well, the C library is distributed in the wheels and that covers a vast majority of linux distros. Pip install works on MacOS. I am also trying to package for Windows. But I am not interested in packaging the library for more exotic platforms.

If you want to (or have to) install from source, you must install the C library and have the headers available. You will also need a C compiler and linker. I do not consider this a bug.

Thank you anyway.
