This is an interesting problem. In principle I should be able to
articulate a correct way of doing things without dealing with issues
about symbolic links, or other quirks of Windows or Cygwin. I don't
know if I can or not, but here is a stab at it. I will be interested in
knowing what you think of my attempt:
I am sure there are many ways to do make the music displays work in a
functionally correct fashion. Here is one:
It seems to me, that a correct way to handle this is make sure that the
HTML is set up right, in which case it should do the right thing
regardless of whether it is in a Windows or Cygwin browser. If Lilypond
is doing the right thing, then we should find the same HTML in any
Cygwin or Windows in a successful packaging of Lilypond in any Cygwin,
Lilypond in Cygwin under Windows, or Lilypond in Windows without
Cygwin. This should be so because HTML is an Internet thing, not an
operating system dependent thing.
Now it gets tricky if you have no control over the Windows concerns when
installing Lilypond under Cygwin. It suggests that we don't want to
care about paths or link types in Cygwin in order to make the HTML work,
because they would be dependent on the Cygwin environment and operating
system. This suggests that a good approach for Lilypond is to make sure
that their HTML files, whether relative or absolute paths, should be
consistent and embedded in a generic directory structure which Lilypond
distributes for all target systems.
On the other hand, if we do care about paths because we want to put
things where they make sense for the operating system of choice, then
the Lilypond packaging should have macro expansion which can map any of
the target operating systems. This is no problem because it is what
make commands are for. However it starts to get nasty real fast if we
want things to work in the mother operating system, such as Windows XP.
It seems to me that in this case the cygwin environment itself has some
responsibility to properly map its paths to the operating system it is
installed within. That sounds ugly to me, and frankly I don't know how
this kind of problem is systematically handled these days. It has been
several years since I have been active.
