Python riscv 64 wheels builder

These scripts allow the generation of riscv wheels to be used as python requirements in the cartesi dapps. The project contains a Makefile with several tasks related to building and managing Python wheels for a RISC-V platform, in the context of building Cartesi Dapps

The available tasks are:

• build: Builds the Python wheels based on the requirements specified in the PIP_REQUIREMENTS_FILE. It uses a docker image to make all the builds specified.
• create-pip-index: Creates the necessary files for the pip index, including the wheel files and the index HTML file.
• clean: Cleans up the pip index directory.
• serve-local-index: Serves a local pip index using the generated wheel files.
• config: Displays the current configuration values.

The configuration variables are:

• PIP_INDEX_URL: The URL of the pip index where the wheel files will be uploaded. Defaults to https://think-and-dev.github.io/riscv-python-wheels/pip-index/
• PIP_TRUSTED_HOST: The trusted host for the pip index. Defaults to think-and-dev.github.io
• PIP_OUTPUT_REL_DIR: The relative directory where the wheel files will be stored. Defaults to ./wheels
• PIP_REQUIREMENTS_FILE: The file containing the Python package requirements. Defaults to packages-to-build.requirements.txt
• PIP_INDEX_DIR: The directory where the pip index files will be stored. Defaults to pip-index
• WHL_BINARY_BASE_URL: The base URL for the binary wheel files. Defaults to https://raw.githubusercontent.com/think-and-dev/riscv-python-wheels/main/wheels
• LOCAL_INDEX_PORT: The port number for serving the local pip index. Defaults to 8000
• TMP_LOCAL_INDEX_DIR: The temporary directory for the local pip index. Defaults to ./local-pip-index

In order to modify the variables used, include the new variables in the make task call. For example:

    make build PIP_REQUIREMENTS_FILE=../mycustomproject/requirements.txt

Build task usage

1. Complete python requirements file with the needed packages
2. Build the requirements by calling the build task

    make build

Contributing

How to Contribute

1. Fork the repository.
2. Create a branch for your contribution.
3. Add the wheels you wish to contribute in the wheels folder.
   • Wheels can be built using the build task.
4. Execute the create-pip-index task to generate the pip index.
5. Submit a pull request.

Warning

Ensure that the wheels are placed in the wheels folder, and that the create-pip-index task was run, so the wheel can be easily installed.
