Issues with building Haxe on windows

[RealyUniqueName]

There are issues with latest versions of ctypes and camlp5 opam modules. This issue is created to not forget to fix them and then update dependencies in opam file.

• [ ] ctypes (needs an update on Haxe side)
• [ ] camlp5 (needs a fix on camlp5 side: https://github.com/camlp5/camlp5/issues/77)

Currently for windows ctypes should be at version 0.17 and camlp5 at 8.00~alpha.

I have a proposal. Introduce a tag for issues concerned with build process and add link to the building page which will point to label:building. Also version (1.7.6) for extlib in the opam file is wrong, 1.7.8 required now.

I have tried to follow the instructions and found that libUV on opam isn't building. I've tried the regular CYGWIN distribution and the special one that comes with the ocaml for windows build. I can't get the latest haxe to compile because I can't get the luv dependency in opam to install.

What is the error?

nothing helpful I'm afraid. I tried building the latest libuv and it failed on cygwin.

I'm going through this mess again at the moment. What helped with the luv situation is following these instructions: https://github.com/HaxeFoundation/haxe/pull/11182
