Lilypond print preview doesn't work in Ubuntu 9.04

[Ilan]

When I press Preview with Lilypond under the File menu, I get :
  KDialog
  ERROR: LilyPond processing failed.
  LilyPond output follows:

The output is totally blank giving no indication what the problem is.
On the other hand, I can do Export -> Export lilypond file ....
and it will export the file. Then I can run lilypond in a terminal on the exported file and that will give me pdf and ps files from my input ly file. It is only the Preview with Lilypond which fails.

The other problem is sometimes the preview command works. I haven't found any connection to find out what causes it to work or fail.

I was wondering if I could somehow put a debugger on this to find out what is going on. Likewise I would like to know if this is a known bug?

Ah. Ubuntu 9.04.  Right.  This kind of thing is why I've been in such a panic
to get the Qt4 port finished and released, before we ran out of time.

It's over a year later, the job isn't finished, and we ran out of time a
little while ago without realizing it.  The problems will be starting
directly.

I haven't updated anything to 9.04 to have a look with my own eyes, but I
think what's going wrong is you no longer inhabit a world where the old KDE
3.x kdialog and dcop command line utilities exist.  You obviously still have
KDE3 libraries, but probably couldn't install these old applications through
any reasonable amount of trickery.

This is bad, but there is no reasonable solution.  It could be solved, yes,
but should I spend my time buying us six months of life for the old obsolete
code, or spend it getting the new code that much closer to release?  I see
that the latter course is the only reasonable one to pursue under the
circumstances.

My vote is without any doubt: forget the old code and work on the new version.

What is interesting is that sometimes it actually works. This must mean that
all the required libraries are in fact in place. Maybe the order in which things are
loaded makes the difference. I could investigate the problem, but it sounds like
I would side track you from the main purpose of the new code.

The main point is the editor works so I can see the score and work on it.
If I REALLY need a particular version to Lilypond, I can export it and then use
a terminal to print it. So a work around exists. Not as nice as a direct Preview
Lilypond, but a work around.

I should mention that while my replacement for this script doesn't do quite as
nice of a job, it does accomplish the basics with a native GUI, and it works
in the field.  This one has been solved for some time now.  I wish I could
say the same about the project packager script, which is a much uglier
version of the same problem.

I tested on an 8.10 box with KDE 4.2 from some backport repository.  It
actually worked in spite of a string of errors about DCOP.  It's mangled, but
not totally broken like I feared.  Not on 8.10 anyway.  It may be the rest of
the way broken by 9.04 though.

Michael,
I don't know if there is any way I could contribute to the development
effort but I would be happy to do what I could.
My experience is mostly with c++ in the Windows world, but I am
moving more and more towards Java to break my dependence upon
Microsoft.

Don't move to Java, move to QT4!

I have all the major subprojects covered at the moment except for rewriting
the project packager script in real code.  I doubt you'd be stepping forward
and raising your hand to tackle that monster, so the best thing I could think
of at this point is testing.

We're going to need a lot of serious field testing of the new Rosegarden
before we can hope to release it.  It's not yet feature complete, and we
haven't yet fixed all the known bugs so far, but it wouldn't hurt to get more
people piddling with it and trying to do something useful, instead of just
knocking out random spot test blurbs the way I've been doing.

Of course the first problem that comes to mind is it doesn't do MIDI recording
yet.  We really need to make fixing that bug a top priority.  I suppose I
have to step back from this invitation while I go try once more to find
what's causing this to break, because it's kind of pointless to invite
testing until that much, at least, is actually working.

Michael,
It seems to me that testing would be a good way to get my hands dirty,
as they say. I am downloading the qt4 branch as I write.
You said that there isn't much point in my trying to test anything until
the MIDI record actually works. While this is true, at least I can get
the feeling of what is involved to build the new software. Also I can
have a peek at it so it won't be totally new.
Then when you tell me there is something to test, I'll have something
to beat on.
If I have troubles building the version, I may be back with questions.

Micheal,
Sorry that I'm back sooner than expected. What is aclocal?
I looked in the Synaptic package manager and I don't see it.

Checked out revision 10480.
ilan@ilan-laptop:~$ cd rosegarden
ilan@ilan-laptop:~/rosegarden$ sh ./bootstrap.sh
./bootstrap.sh: 2: aclocal: not found
ilan@ilan-laptop:~/rosegarden$

Ilan

[Ilan]

I find this with Google:

The aclocal program creates the file `aclocal.m4' by combining stock installed macros, user defined macros and the contents of `acinclude.m4' to define all of the macros required by `configure.in' in a single file. aclocal was created as a fix for some missing functionality in Autoconf, and as such we consider it a wart. In due course aclocal itself will disappear, and Autoconf will perform the same function unaided.

 

user input files   optional input     process          output files
================   ==============     =======          ============

                    acinclude.m4 - - - - -.
                                          V
                                      .-------,
configure.in ------------------------>|aclocal|
                 {user macro files} ->|       |------> aclocal.m4
                                      `-------'

Maybe Ubuntu decided that it is time for it to disappear? Is there a way to make bootstrap.sh use Autoconf instead?

It's in the "automake" package in Ubuntu (for some reason).

Thanks Chris. Can I be so bold as to ask for some more help?
The config isn't working. I looked in the log and there was a ton of files where it failed.
It complained about not finding a directory for cpp, so I checked that c++ was
installed. I'll include the screen shot to show that I think it is.
This is what I get in the terminal:

configure: error: in `/home/ilan/rosegarden':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

I think that it isn't too far off the mark, but clearly I'm still missing something.
Thanks,
Ilan

Try also installing the following Ubuntu packages (or meta-packages):
build-essential xutils-dev ladspa-sdk dssi-dev libasound-dev liblo-dev
liblrdf-dev fftw3-dev libqt4-dev libjack-dev

You'll have some of them already no doubt, but there's no harm in
asking apt to install them all, it'll just skip the ones you already
have.

Yeah, and Chris (Fryer) also needed to install some weird X11 package to
provide...  I forget what.

I added a table to the "contributing" page at
http://www.rosegardenmusic.com/wiki/dev:contributing a few days ago, intended
to answer this sort of question in the future.

It was xutils-dev to get makedepend, I see looking now.

The chart isn't complete, and I think I kind of dropped that ball and got
sidetracked.  Everyone else should please feel free to edit that page.

Thanks again Chris. It doesn't yet work and I'll include the config.log file.
First of all it complains about a missing header file:

conftest.cpp:8:28: error: ac_nonexistent.h: No such file or directory

I put in all of what you suggested. Then it complained about LIRC
which I also put in. LIRC had a dialog box where it asked me how to
configure it. Since I didn't have a clue, I just used the defaults.
It is still complaining, so something maybe isn't configured correctly.

I'll also include a screen shot on the LIRC

Sorry, you need the liblircclient-dev package.

The ac_nonexistent.h error is a red herring -- it's supposed to be
nonexistent.  Your problem is just the lack of the lirc client library
headers (as opposed to the lirc server).

It looks like you installed the end user package, not the -dev package.  You
want -dev versions of all this stuff.  Looks like

  liblircclient-dev

in this case

I'm glad I decided to try this up front, before there is something I can actually test.
This time it is my fault. I didn't find any fftw3, so I installed fftw.
Maybe I want that root-plugin-fftw3?
I doubt it is the documentation it is complaining about.
Here is the config.log again

This one always trips me up.

In Ubuntu 9.04 it is:
libffw3-dev

Sincerely,
Julie S.
