Building nvmefs 🛠️

To build nvmefs, it is necessary to install the required tools beforehand. You can find more information about what is necessary to build nvmefs in the projects readme

Alternatively, you can use the development container, which comes with all prerequisites pre-installed.

After prerequisties are installed type in:

cd nvmefs/
GEN=ninja make release

The build binaries are stored in nvmefs/build/release and the extension that can be loaded into client programs is stored in nvmefs/build/release/extension/nvmefs/nvmefs.duckdb_extension
