When I run lilypond from the desktop, it does not start up lilypad

shell, cd to the LilyPond usr\bin directory and then run lilypond, it
DOES start up lilypad. I thought it was a problem quoting spaces in
the install directory, so I uninstalled and re-installed in a
directory without spaces, and it's still not working. I dug a little
deeper, and I think now that the problem is that lilypond.exe is not
affecting the environment at all. I put the following batch file in
c:\windows to see what lilypond.exe does to the environment:
Running
LILYPOND_VERBOSE=1 lilypond
prints changed environment settings.
Didn't work for me. When I cd to lilypond\usr under Windows command
prompt and run:
set LILYPOND_VERBOSE=1
bin\lilypond
I don't get any output, nor does lilypad start up. For some reason
lilypond returns back to the command prompt even though it's still doing
stuff in the background - like trying to run lilypad, which I can tell
it's doing because a dos-box pops up briefly with an error message
something like 'unknown command'.
Now, here comes the REALLY weird part... At the windows command prompt,
if I run
set LILYPOND_VERBOSE=1
bin\lilypond > out.txt
It DOES run lilypad.exe to bring up the "Welcome_to_LilyPond.ly" file!
The out.txt file is empty. Any idea why redirecting stdout would have
any effect? I can't think of a reason...
If I instead run
set LILYPOND_VERBOSE=1
bin\lilypond --help > out.txt
Then the contents of out.txt are:
GNU LilyPond 2.5.31

LILYPOND_DATADIR="/usr/share/lilypond/2.5.31"
LOCALEDIR="/usr/share/locale"
Effective prefix: "D:/LILYPOND/USR/share/lilypond/2.5.31"
FONTCONFIG_FILE="D:/LILYPOND/USR/etc/fonts/fonts.conf"
GS_FONTPATH="D:/LILYPOND/USR/share/gs/fonts;C:\WINDOWS/fonts"
GS_LIB="D:/LILYPOND/USR/share/gs/lib"
GUILE_LOAD_PATH="D:/LILYPOND/USR/share/guile/1.7"

So, it would seem that LILYPOND_VERBOSE actually does work, but only
when there's a command-line argument. The PATH looks like lilypond is
added correctly, which I guess isn't surprising given that redirecting
stdout magically allows lilypond to execute lilypad.
Note: I tried running
bin\lilypond > nul
but then lilypad doesn't pop up.
I experimented with a few things to see whether the stdout-redirect
might be a work-around for the time being since the symptoms are so
weird that debugging it might not be cost effective.
First, I changed the lilypond shortcut on the desktop to run:
C:\WINDOWS\COMMAND.COM /C "D:\LilyPond\usr\bin\lilypond.exe" >
c:\lilyout.txt
And, when I double-click, lilypad does start up. Progress at last! :)
Second, I changed the "&Generate PDF..." explorer command for .ly files
to run:
command.com /C "D:\LilyPond\usr\bin\lilypond.exe" --verbose "%1" >
c:\lilyout.txt
And, when I double-click on an .ly file, it actually creates the PDF
file! Yeah! However, command.com thinks the world should be DOS-ey, so
it munges the ly-file pathname to 8.3, meaning that what should be
example-1.pdf actually comes out as EXAMPL~1.pdf.
I'd prefer to re-direct to a file in %TMP% or %TEMP% (which is the
Windows standard?), and then remove it once lilypond.exe is all finished
to be nice and tidy. And of course, using real WIN32 long filenames
would be good. So, if I have some time in the next few days, maybe I'll
try to write a front-end that does what I'm using command.com to do
right now. Even better would be to use a pipe (if it works), and have
the front-end display the results. Probably won't have time, though. :(
Anyway, unless you have an idea how to debug why lilypond.exe isn't able
to exec lilypad.exe or gs.exe normally, at least we might get something
working with the stdout redirect hack...
On 2nd thought, I do have an off-the-wall possibility of what might be
going on. Is there any chance you're linking lilypond.exe with the
-mwindows switch? It's been a while, but I seem to recall that switch
was for windows applications that use the WinMain() entry point. Since
lilypond.exe uses the main() entry point, linking with -mwindows might
be causing WinME to get confused.
One last thing on a totally different topic...
I grabbed Scott Joplin's entertainer.ly and entertainer-let.pdf off the
mutopia web site a while back. If I use lilypond 2.5.31 to generate a
new pdf, it's huge. The old was 91KB, the new is 746KB! Viewing with
acrobat reader, the quality of both look similar. The old has a
smoother brace on the grand piano staff (is that what's it's called? -
I'm drawing a blank right this second), and the new has more consistent
weight (and not so bold) of staff lines. (I like the old smoother brace
and the new less bold staff lines, but of course it's just personal
preference). Anyway, I was shocked at the difference in file size. Is
this to be expected? I had to convert the .ly file up to 2.5.31 - could
that have any effect? I've skimmed the typeset music, and it all looks
basically the same.
