I just did

haxelib remove hxcpp
haxelib git hxcpp https://github.com/HaxeFoundation/hxcpp.git

And after haxe compile-some-cpp.hxml, i see:

This version of hxcpp (me/haxe/haxelib/hxcpp/git/) appears to be a source/developement version.
Before this can be used, you need to:
 1. Rebuild the main command-line tool, this can be done with:
     cd tools/hxcpp
     haxe compile.hxml
 2. FOR HXCPP API < 330:
    Build the binaries appropriate to your system(s), this can be done with:
     cd project
     neko build.n

Would you like to do this now [y/n]

y<Enter> has no effect and timeout happens (at least on macos)

I've seen this happening for ages on linux as well, works fine on windows though so I've not bothered to look into it. On the handful of times I've ran into this I've manually rebuilt the tools instead.

It doesn't work when running an hxml, but it works fine when running hxcpp directly:

$ rm hxcpp.n                
$ haxelib run hxcpp                                    
This version of hxcpp (/path/to/hxcpp/) appears to be a source/developement version.

This is a problem with haxe redirecting stdin, basically: HaxeFoundation/haxe#10742 and HaxeFoundation/haxe#11424. If it used to work in the past, it probably broke during the frontend refactoring: HaxeFoundation/haxe#10629
