[jazzplusplus-devel] "Floating exception"

[Kevin C. <ke...@co...>]

Hiya,

I built wxWidgets and Jazz++.  I didn't install wxWidgets, but in
stead I configured jazz to use ../../blah/blah/blah/wxblah to build.
When I start ./jazz in the src dir I get this error message

(jazz:2261): Gtk-CRITICAL **: gtk_file_system_unix_get_parent: assertion `g_path_is_absolute (filename)' failed

and then a window pops open to ask me where the jazz.cfg file is.
After clicking on that file I get a "Floating exception" as jazz 
crashes.

I had these defined in my environment from my historic use of Jazz++

JAZZ=/usr/local/jazz
WXHELPFILES=/usr/local/jazz

Undefining them does alter the behavior.

Any thoughts?

Thanks....

How did you do that?

What version of GTK did you use?

This looks similar, but not identical to, messages posted by Robert 
Vogel in his screen dumps.  I can't get at my Linux box to try, but I 
don't think I've seen these.  I could be mistaken.

Do you have a file called .Jazz under your home directory?

If yes, what's in it?

If not, could you create on and put the following in it...

[Paths]
Conf=LOCATION_OF_CONFIGURATION_FILES

Where LOCATION_OF_CONFIGURATION_FILES is an absolute path to your 
configuration file directory.  I have the following...

[Paths]
Conf=/home/pstieber/Jazz++/jazzplusplus/trunk/jazz/conf/

Let me know is any of this help.  I might commit a version with some 
debug code to help us figure out what is going on.

I created the file 'jazz' in my home directory, but when I started it the 
dialog box appeared asking me to identify the location of the jazz.conf 
file.

At this point I navigated the dialog box to 
(home)/jazzplusplus/trunk/jazz/conf at which point it does find a jazz.conf 
file. On open, it says it can't find the config file and it locks up looking 
like the attached screen shot.

It looks like the path error occurs before the dialog box appears When I 
navigate to the cfg file it produces a dialog box warning, and then locks up 
for a number of seconds.
After a while it says the box is not responding and I force quit. Again, 
here is a screen shot.

...so I rebooted. It must be that it now finds the files I added  (jazz is 
in my home directory now) because it comes up with the player screen. Only 
thing is alsa doesn't see it anymore. :(

Sorry for taking so long to reply.  I just got back from a week long 
vacation.

RV = Robert Vogel
RV> I created the file 'jazz' in my home directory,

I take it you mean the Jazz++ binary?

RV> but when I started it the dialog box appeared
RV> asking me to identify the location of the
RV> jazz.conf file.

Jazz++ will do this if it cannot find the configuration file when it 
starts.  This may occur when you first run the executable or if you move 
or erase the configuration file.  The code is prompting you to indicate 
the location of the configuration file.  It will record this location 
once you specify it, and you should not be prompted for it on successive 
Jazz++ session (if you don't erase or move it, of course).

RV> At this point I navigated the dialog box to
RV> (home)/jazzplusplus/trunk/jazz/conf at which point
RV> it does find a jazz.conf file.

Was it jazz.conf or jazz.cnf?

RV> On open, it says it can't find the config
RV> file and it locks up looking like the
RV> attached screen shot.
RV>
RV> It looks like the path error occurs before the
RV> dialog box appears.  When I navigate to the cfg
RV> file it produces a dialog box warning, and then
RV> locks up for a number of seconds.
RV>

RV> and I force quit. Again, here is a screen shot.

Looking at you screen shot, it looks like the configuration file was 
found, and it successfully read most of it.  See the line that indicates 
the reading of "gs.jzi".  This file name is specified in the Jazz++ 
configuration file.  The configuration file is ASCII.  You can use

$ cat jazz.cnf

to view the contents.

The "gs.jzi" file is also ASCII, so you can use "cat" to view the 
contents.  It includes the other configuration files ("gsdrmset.jzi", 
"gmdrmnam.jzi", "gsvoices.jzi", and "ctrlnam.jzi") listed in your screen 
shot.  It looks like all of these were successfully read.

My current guess is the information at the bottom of the jazz.cnf file. 
  It has ALSA input and output devices and a default MIDI file to load. 
  The path for the default MIDI file has a path that includes on of the 
prior Jazz++ developer names in it and is incorrect for your machine.

Try removing the following lines from jazz.cnf using your favorite editor.

.alsa_input_device 1
.alsa_output_device 2
.startup_song /home/joakim/music/moogtest.mid

Did that help?

RV> ...so I rebooted.

You could just kill the jazz process...

You had to reboot the machine :-(

I'm sorry about that.  Maybe when the code attached to an ALSA device 
(indicated by the line that says "created client:port 136:0") and it 
froze, not gracefully disconecting from the ALSA driver was the problem.

RV> It must be that it now finds the files I added
RV> (jazz is in my home directory now) because it
RV> comes up with the player screen.

On the next invocation it should automatically find the configuration file.

RV> Only thing is alsa doesn't see it anymore. :(

Are you sure you rebooted the system?

BTW I'm downloading the Debian DVD iso's.  Are you using 4.0 r3?

Kevin,

Last night I loaded Mandriva 2008.0 and all of the required development 
tools on an extra 80 GB HD I had lying around.  I have been making 
changes to the configuration startup code.

I'm going to modify my wxWidgets build instructions on the web site to 
make sure the Jazz++ custom build and install of wxWidgets doesn't 
conflict with any "standard" version already loaded by the OS.

I'm also going to add Jazz++ build and install instructions so 
developers do not use the jazz.cfg file under the development 
directories.  This causes problems because the code frequently rewrites 
the jazz.cfg file and if you update using svn there will be conflicts 
that cause problems in Jazz++ on successive startups.

I'm happy to report I successfully built and installed wxWidgets 2.8.7 
and built, installed, and ran the current trunk version of Jazz++ on the 
Mandriva box.  No floating-point exception :-)

There is a problem when I play a midi file and exit Jazz++.  It leaves 
the jazz process running and the only way I can kill it is to reboot :-(

I'll have to look into that.

Let me Know how it's going,
Pete
