I've most likely screwed up in the definition, but just making this issue in case I didn't.

I can look at this, but I need to have access to Eina.h and its contents. There must be something missing to support.

[samis]

No problem, it's one of the development headers for an opensource library. The file can be viewed in the git repository at https://git.enlightenment.org/core/efl.git/tree/src/lib/eina/Eina.h

[asterite]

It seems the issue is that some structs use va_args or __builtin_va_args... I'm still not sure how to map those or where those are defined, I'll keep investigating.

[samis]

http://man7.org/linux/man-pages/man3/stdarg.3.html might help.

[asterite]

@samis With HEAD you can now generate bindings for eina. The headers have some nested structs inside structs and these aren't supported right now, I'll try to fix that next.

[asterite]

And now nested structs are also supported! \o/
