Re: Several problems with 2.5.27 version on Windows ME

[Brynne and Russ Jorgensen]

I upgraded this evening to 2.5.29, so these comments don't necessarily 
apply to the 2.5.27 version I originally reported some issues with...

Under WinME, the echo output is

        ECHO is on

like env var a is not set.  But, if you just do

        set

you'll see there is an environment variable whose name is

        "a=hi there"

double quotes and all without any associated value.  Probably not what 
you want!  And, it causes problems with gs.bat.in - see below.

Apparently the CommandEnvSize setting in SYSTEM.INI dates way back to 
Windows 3.0 and is still supported.  So, all the Microsoft URLs I could 
find would seem to most users to be out of date.  I don't know whether 
you'd want to include this in a popup, but the following URL does a good 
job of explaining what to do:  http://www.allenware.com/mcsw/bus.htm.

There are still problems with the lilypad installed with 2.5.29 under 
WinME.  When you run lilypond.exe without any arguments expecting it to 
start up lilypad.exe on the Welcome_to_LilyPond.ly file, one of two 
things happen.  (Note: I first renamed lilypad-ascii.exe to 
lilypad.exe... :)) When I run the LilyPond shortcut on the desktop, I 
just briefly get a dos-box popped up that says "Bad command or file 
name." but lilypad.exe never shows up.  When I run lilypond.exe from a 
command prompt, lilypad.exe DOES bring up its window, but it gives the 
following error:

File '0:0 
"D:/PROGRA~1/LILYPOND/USR/share/lilypond/2.5.29/ly/Welcome_to_LilyPond.ly".ly' 
does not exist.

If I right-click on a .ly file and do either "open" or "Edit source...", 
I get a similar (but not exactly the same) error:

File 'D:\Program 
Files\LilyPond\usr\share\lilypond\2.5.29\ly\grace-init.ly".ly' does not 
exist

I probably misunderstood exactly what was supposed to be fixed in 
2.5.28.  As before, I still don't have time to debug it! :)

Well, the symptoms are different, but the ps file is still not 
compatible with gsview.  Here's the error I got this time:

Unfortunately, lilypond.exe in 2.5.29 still isn't generating a PDF file. 
 But, I did find a few bugs that might help get there in 2.5.60...

Using a dos-box, I run the following:

    "D:\Program Files\LilyPond\usr\bin\lilypond.exe" --verbose example-2.ly

There is no output on the console, and I get the following files created:

    example-2.log
    example-2.ps

Looking at example-2.log, the last couple of lines are:

    Converting to `example-2.pdf'...
    Invoking `gs   -dCompatibilityLevel#1.4  -sPAPERSIZE#"a4" -q 
-dNOPAUSE -dBATCH -r1200  -sDEVICE#pdfwrite -sOutputFile#"example-2.pdf" 
-c .setpdfwrite -f "example-2.ps"'...

Although lilypond.exe says 'Invoking gs ...', I never got any output one
way or the other from the gs command, nor did the example-2.pdf file 
show up.

So, to check whether gs.exe is working, I created a doit.bat script with 
the following command and ran it from the dos-box:

    "D:\Program Files\LilyPond\usr\bin\gs.exe" -dCompatibilityLevel#1.4 
-sPAPERSIZE#"a4" -q -dNOPAUSE -dBATCH -r1200 -sDEVICE#pdfwrite 
-sOutputFile#"example-2.pdf" -c .setpdfwrite -f "example-2.ps"

and got the following output:

    GPL Ghostscript 8.15: Can't find initialization file gs_init.ps.

I don't know how you do it, but it looks like you're creating gs.exe 
from the gs.bat.in file, so I experimented with gs.bat until I finally 
got it working. The main problem was with quoting environment variables 
- see above.

I'm attaching the updated gs.bat.in file.  Since I don't know how to 
make it into gs.exe, I can't test whether that fixes the problem of 
lilypond.exe going all the way from a .ly file to a .pdf file, so I'll 
wait for the next dot release...

One last weird bug I discovered.  If you run lilypond.exe on the init.ly 
file (I just happened to choose it for a test, not realizing that it 
looks like something lilypond always reads during startup), it looks 
like you get an infinite loop.
