Trying to run make deps results in the following errors:
I have tried several fixes and nothing seems to be working, please let me know if you have any idea on how I can fix this.
I think that you need to install a cygwin package which provides a file libssl.pc (or similar). In Debian-based GNU operation systems it is called libssl-dev.
Also, in 2021 I would recommend to use WSL instead of cygwin on Windows

It seems that the some system dependencies are not installed correctly with depext. Could you raise an issue to GitHub - fdopen/opam-repository-mingw: windows package repository for OPAM (mingw and msvc) when you have time?

This looks like an OCaml.org build. It is currently being documented, but the recommended way for building the ocaml.org site on a Windows machine right now is using WSL. See the related issues:
- Error while setting up ocaml project using WSL
- Improve the Success Stories page · Issue #1258 · ocaml/ocaml.org · GitHub
There are a lot of scripts and Makefiles so it seems this is the quickest way to contribute is to use WSL. It also seems @YASHI_VIJAY has already managed to build the site this way so it is a little more tried and tested :))

Just missing depexts informations:
opam update
opam pin add -n ssl 0.5.9 [*]
And try it again.
([*] The libssl package shipped by cygwin is not longer maintained and incompatible with the latest release of ocaml-ssl. Don’t use it for anything except local testing.)

That was many times faster response than I expected.

Thank you. For some reason WSL isn’t responding on my laptop so I had to look for an alternative.
Currently facing this error on my ubuntuOS while trying to build the project again, and I was wondering if this is related to the current issue discussed here.
I have successfully built the ocaml.org before now on my system, but I want to redo the whole process again for the sake of documenting my journey to help others when needed.

/usr/x86_64-w64-mingw32/sys-root/mingw/bin (or /usr/i686-w64-mingw32/sys-root/mingw/bin) is probably not in your $PATH (or at a wrong position, so that ssleay32.dll is hidden by another file with the same name).
Add it with eval $(ocaml-env cygwin)
Thank you @fdopen got a new error after running that command
That’s an error at the source code level. The code is not compatible with Windows.
Somewhere, it uses open_in/open_out, but should have used open_in_bin/open_out_bin. Or set_binary_mode_out stdout / set_binary_mode_in stdin is missing.

Thank you once again @fdopen
Now installed on an Ubuntu system and I get the error below after I run make deps
Have you encountered this before? If yes, please how do I get it solved.
It says that bwrap should be installed. I recommend
- to check if it is installed
- if it is and error still happens, you can comment
wrap-*lines in~/.opam/configto disable it
@Goodiec can you check if replacing open_in and open_out in the script/http.ml files at lines 93 and 104 fixes your issue?

Thank you @Kakadu was able to successfully run make deps but I get the error below when I run make
Thank you @mseri but I have already started the process again on Ubuntu.
Ran eval $(opam config env) and that got rid of the ocamlfind : Command not found error.
