Alexandros Liarokapis e36b4564d2 nanopb: 0.4.6 -> 0.4.8 ... This commit: - Bumps the nanopb version - Adds all runtime configuration options - Implements proper cross-compilation support which is the main use-case of the library. - Uses newer `finalAttrs` form of `mkDerivation` to allow for easier attribute overrides. The cross-compilation support is achieved by splitting the package into two sub-packages consisting of the build-time generator and the runtime library. Nanopb explicitely supports this by providing specialized `GENERATOR` and `RUNTIME` CMake configuration options. The top-level package uses `propagatedNativeBuildInputs` and `propagatedBuildInputs` to propagate the sub-packages and also adds convenient symlinks to make certain use cases easier. == GENERATOR == The generator is a mostly ready-to-be-packaged python module tree. We patch the library to also include the missing `__init__.py` and we also fix the `PYTHON_INSTDIR` variable to follow best practice and to prevent the library from attempting to install to a global directory. We package the python module using `buildPythonPackage` and internally override python in order to wrap the `nanopb_generator.py` executable. We do *not* wrap `nanob_generator.py` due to it also being imported directly from python when used through `protoc-gen-nanopb`. == RUNTIME == The runtime is a simple library that consists of the common functionality among generated headers/sources. It is configured through `preprocessor definitions` and consumer projects *must* be compiled with the same definitions. This is currently achieved by exposing all configuration options through the top-level overrides and patching the CMakeLists.txt so that the definitions are added to the to-be-installed CMake targets as PUBLIC properties.		2024-06-26 22:15:27 +03:00
