I am having nightmares trying to decide what to do with the Rust version based around generate on demand or on version change. With bindgen in Rust though, there is no need for manual tweaking so automated is possible. Except that it puts a massive dependency burden on any project using it. DStep generated bindings tend to need some manual tweaking that cannot be automated, which is surprising given that bindgen can do things without manual intervention for Rust. > You may want to consider using dpp instead if possible. DPP cannot build "out of the box" on Debian Sid, so I have not actually tried it. There are three audiences here: 1. People building libraries for their own use on their own machines. 2. People building for OS distributions. 3. People building to distribute to others who will not be building for themselves. Categories 1 and 2 could probably cope with automated generation despite the huge dependency burden, assuming there are no version conflicts – this seems to be a massive unsolved problem with Rust/Cargo/crates.io :-( . Category 3 needs as light a weight and speed of build as possible, and the ability to dynamically adapt to the APIs and ABIs of execution at run time. On the other hand, suspect I may be the sole user of RUst and D bindings to libdvbv5! -- Russel. =========================================== Dr Russel Winder t: +44 20 7585 2200 41 Buckmaster Road m: +44 7770 465 077 London SW11 1EN, UK w: www.russel.org.uk
