# Trezor
## Messages rebuild
Install `protoc` for your distribution.
- `protobuf-compiler`
- `libprotobuf-dev`
- `libprotoc-dev`
- `python-protobuf`
Python 3 is required. If you don't have python 3 quite an easy way is
to use [pyenv].
It is also advised to create own python virtual environment so dependencies
are installed in this project-related virtual environment.
```bash
python -m venv /
```
Make sure your python has `protobuf` package installed
```bash
pip install protobuf
```
Regenerate messages:
```
./venv/bin/python3 src/device_trezor/trezor/tools/build_protob.py
```
The messages regeneration is done also automatically via cmake.
[pyenv]: https://github.com/pyenv/pyenv
