Hi Alexandre,
The Hoa library is pretty complicated to compile, it requires updates and the help files and tutorials are based on the Cream library that is also deprecated... my development process was really chaotic at the time (sorry)! Unfortunately, I think I'll never have the time to maintain these libraries anymore, even if I really wish I could do it. But fortunately, the CEAMMC library integrates most of the Cream & HOA objects, you might ask the CEAMMC devs what remains to be done instead of doing another distribution? I'm pretty sure they'll be happy to get help!
