Thank you Ingo for your reply.
Yesterday I forgot to attach the file with the compiler error messages.
Yes I was compiling the bfs_shell and as you can see in
system_dependencies.h if is defined BFS_SHELL there is no inclusion of
ByteOrder.h.
I am going to open a ticket in short as you suggested and if I manage
to fix it myself I'll attach a patch too.
I'm not a Haiku developer, but now I've not choice to become one as
Salvatore is making my life miserable :). Kidding aside, I'd like to
become one.
I haven't chosen an area of interest yet but I am reading Dominic's book
on BFS it becomes more interesting page after page so maybe I'll start
by having a look at the Haiku BFS implementation.
Thank you again.
Marco
