You’d think at the least one could ask for more informative errors…

Maybe we should start from here with the original C API instead of the high-level wrappers.

I wrote a binding generator here:

Wow, looks like you’ve done a lot of work on this! Those bindings look great! I know I’ve kind of made a mess of things, Frankenstein together parts of the original code and now 2 branches. I’m guessing the name of the last commit “no luck” means it didn’t work out?

Yeah, it didn’t work . If I could have more spare time, I’d like to try reimplementing the official example paex_record.c with the bare C API, but today is the last day of GW.

No problem! I should be working on other things too…
