At the end of the day I've managed to build and start it under the Windows, and it works correctly.)
The only problem is src/qeditas.ml, line 331:
let dur = open_in_bin "/dev/urandom" in (*** this is to compute a nonce for the node to prevent self conns; it doesn't need to be cryptographically secure ***)
I've used a real file with real path instead of the "/dev/urandom" as a simplest workaround, I need more OCaml knowledge to fix it correctly, I can't do it right now.
I'll share Windows build instructions later, after I test it on clear Windows installation and choose the simplest way to build the project.
That is great to hear! Thank you for your work.
Regarding the call to /dev/urandom, this could be replaced by something giving random numbers that do not need to be cryptographically secure. However, in the end we will definitely need to be able to obtain cryptographically secure random numbers. In linux I can get these from /dev/random. There must be some way to obtain cryptographically secure random numbers in Windows, in a way that can be called from OCaml.
