Re: Compilation error with ocamlnet-2.2.9

Well, ocamlnet-2 shows the signs of age. If you build it yourself, I
recommend to switch to ocamlnet-3 - which is not yet released, but up to
date with respect to changes in header files. There might be still some
(minor) instabilities, though.

Alternatively, look into this patchset:

https://godirepo.camlcity.org/wwwsvn/trunk/godi/godi-ocamlnet/patches/

That should make ocamlnet-2.2.9 buildable.
