Add support for pre-release DuckDB versions (e.g. "pre" feature). about duckdb-rs HOT 5 CLOSED

It's a reasonable requirement, but may not easy to implement as duckdb don't have a pre-release build for us to depends on, which means we may need to checkout the branch or commit-id to build the version we need, this may not that easy.

For now my suggested solution might be use the buildtime_bindgen feature, and bring your own duckdb release and header file.

from duckdb-rs.

Currently our build.rs depends on the amalgamation duckdb.cpp to build, if we don't have that file, it means we need to involve cmake in the build process, which will make the build.rs much more complex than current solution

from duckdb-rs.

Okay. That makes sense. I understand it can complicate the process and that may be undesirable. As an FYI, though, it's not necessary to involve CMake or to "build" anything:

git clone https://github.com/duckdb/duckdb
cd duckdb
python3 scripts/amalgamation.py

The above will create src/amalgamation/duckdb.{cpp,hpp} and runs in a few seconds (but does require Python 3, which may be a reasonable requirement to already be installed).

I'm fine doing this myself, though. Is there an example of using buildtime_bindgen and pointing to those files (or that directory) I can reference?

Thanks!

You could refer to the CI process https://github.com/wangfenjin/duckdb-rs/blob/main/.github/workflows/rust.yaml#L37-L60

The idea is download the binary and export the path, and then use the buildtime_bindgen feature will do codegen using the exported header file.
For your case is compile the lib and copy the binary to somewhere and export the path

Close as it's not in the scope of this project
