Re: [jazzplusplus-devel] Debian Build and Run Attempt

[Robert V. <vo...@ct...>]

False alarm. Getting the cfg file out of my home directory changed
everything. First it opened a dialog that allowed me to specify the
device environment, then I was happy to see that the sequence is now
working, and the metronome no longer hangs...although I can't really
hear the metronome yet. 

Sounds good.

Is the reccord button implemented ?

Bob

[jazzplusplus-devel] Patch Submission - htdocs bugreports content - first draft

[D.B. M. <db...@ho...>]

Greetings,

Pete,  here's my proposal for the majority of content for the bug reports webpage.
As opposed to simple editing and correcting of existing content, this is new content
submitted for your approval. Please review (holding in mind certain points detailed
 below),  and deal with it as you see fit.

There are things missing/omitted from this draft that need be addressed. Exampled
paths are relative to linux, as are some of the command sequences.

*Add Windows and Mac paths relative to examples.as required
*Include any Windows and Mac specific commands or methodology if required

See attached file :- htdocs-bugreports-instructions.patch.gz

**BE WARNED** -- although the formatting output looked fine here, I noticed
the patch looked a little strange...almost like my CR turned itself off. Too tired
to deal with that now - supplied as a patch with a warning that WYS is not 
nearly always WYG....


...And of course, to everyone else here - have a look at the content, and see what
you think. Anything missing? Things I shouldn't have said or ought to have said?
I'm sure everyone knows the drill, and understands criticism both good and/or bad
is expected and always welcome.


I'll checkout a build of rev.525 in the morning. 

Regards,

Donald B.

Hmmm....one of my house-mates has a Debian Etch installation on
ix86 and it has an emu10k1 fitted to it, so I might actually try latest
against his hardware/Etch here later to compare results....

Thanks for trying this with the code in such a preliminary state.  I'm 
just trying to get a MIDI file loading and playing on all platforms at 
this point.

Try the suggestions above...

1. Update the code and rebuild.  You can copy the new jazz binary over 
the one in TestInstall/bin.
2. Rename the config file in your home directory so it isn't used.
3. Make sure the .alsa_input_device and the .alsa_output_device entries 
in TestInstall/share/Jazz++/jazz.cfg are set to -1 so you will be 
prompted for input and output devices.
4. Run the version in TestInstall/bin.

Let us know how it goes.

Your email to them could

1. indicate we are in the early stages of reviving Jazz++
2. point to the new web site
3. point out that the keepers of the old site blessed this project
4. mention the link on their site is broken so they should either remove

My current guess is an invalid input or output device index.  Could you

[jazzplusplus-devel] Question about external link references

[D.B. M. <db...@ho...>]

Greetings,

               As I scour the 'net looking for pertinent documentation
resources, I'm coming across references to jazz++ that point back
to the old jazzware website. This is unfortunate - quip;

Unable to determine IP address from host name for www.jazzware.com

One such document, is the 'Linux MIDI HowTo' but there are others.

My question is, do we wish to email such documents' authors, kindly
requesting them to update their links?? I primarily ask this because
of jazz++'s early development stage..ie; if there were fully functional
tarballs available of any kind for jazz++ now, I wouldn't ask - I'd just
send the emails to the authors concerned and report that action here.

Let me know, as it's fairly easy (and convenient) for me to include 
such tasks in my current activities here....


Regards,

Donald B

[jazzplusplus-devel] Debian Compile ...

[Robert V. <vo...@ct...>]

I tried compiling Jazz++ on my Debian Etch stable system. It looked ok
throughout the build process, and it produced an executable. When I
tried opening the executable, it didn't prompt for a configuration file,
but it found one in my home directory. I'm not sure it is the correct
jazz.cfg though. (attached)

When I execute from the TestInstall it does open a window and a midi
file is visible there. It doesn't play though. It only makes a few low
cello-like sounds...about the first two bars... and then the curser
stops and advances no further. In another window I have an alsaconnect
gui...which does not actually see jazz++. Jack doesn't know about it.

I connect my Yamaha ES8 keyboard to a UX16 usb connector which is
configured with alsaconnectgui. Usually I can use the keyboard to
connect with a software synth or I can use Rosegarden to drive using the
alsa connectivity. Anyway Jazz++ doesn't appear to be recognized by
alsa. It doesn't show up in the alsaconnect gui.

Rosegarden complains every time I start it that the 'system timer
resolution is too low'. I know I need to find a RT kernel, but I've been
too cautious to try one yet. Soon. That's why I need to be able to
connect to an external device or to a soft synth.

Here are results for the menus.

The 'preferences' on the file menu looks to be a stub.

I didn't get far enough along to try the edit functions.

The metronome causes an immediate segmentation fault and a hard crash.

The Jazz++ harmony window looks nice. If I right click on the various
chord buttons they play the actual chords with a guitar-like sound. I
have Jazz++ set up as a GM synth. I can see the ux16 and click on it,
but it doesn't do anything.

The audio menu seems to be all stubs. Is that right ?

Help menus are unpopulated. Probably I missed the 'make' command for the
documentation (?)

I'm attaching the config.log for your consideration.

I actually know about gdb, backtraces and so forth. I doubt one could
build a Free software based systems for as long as I have without needing this
'software scalpel' at some stage or another. However, I tend to 'follow the book'
very closely, as to expose 'userland', because sometimes that's a useful strategy.
So we see here...the configuration switch '--enable-debug' (which is part of
the current svn build instructions anyhow), and the quick gdb primer of how
to obtain useful debugging information to help developers out here.

I think somehow that for as long as a debug build is the default build, these
brief gdb instructions would be quite pertinent for users to read somewhere
on the website.  Test builders are a valuable resource, and so I believe it might
useful to include such documentation on the site so users who do build jazz++
can quickly and easily supply (and know how to create) useful information 
if they find their jazz++ build crashes. If nothing else, it'll save having to spell
that backtrace passage out, over and over again. Remember, everyone building
from svn is effectively a test builder at present.

Let me know what we think here - if it sounds like a good idea and we agree,
I'll edit the htdocs in some appropriate spot to include such instructions.

Just a further note on this -- as I mentioned in a previous posting, 
I'm keen to test out and document jazz++'s interoperability and setup
with other midi based applications on linux. Last night, I got around
to trying the AlsaModularSynth (AMS) application with jazz++.

To use AMS without a hardware midi/synth soundcard, relies on a
very similar setup to jack/fluidsynth/qsynth. One starts AMS with 
the --jack cmdline option, and when jazz++ is started and prompts
for an output device, the user selects the AMS output device entry.

Yes...it works, and curiously enough it never once spawned the above
crash in a two hour session of me mucking around with things, stopping
and restarting things...I could not seemingly reproduce this error above
using jack/AMS and jazz++ at all. Nor did it ever steal my mouse and
keyboard I hasten to add -- everything behaved itself.

I'm no coder, but I thought I'd mention this here, just in case there's
more to the above error than immediately meets the eye.

Donald B

I just tested the current svn on a Fedora 8 box (kernel is SMP, x86_64 
version of  2.6.24.5-85.fc8).  If I start jackd using qjackctl, then 
start fluidsynth using qsynth, hook things up correctly, then start the 
jazz binary, I am presented with the following options for output...

Midi Through Midi Through Port-0
Client-128 qjackctl
FLUID Synth (7569) Synth port input (7569:0)

7569 is the process ID for qsynth.  If I select the last option, I can 
here the loaded MIDI file when I hit play.

I loaded the following packages using yum to get all of this working.

qjackctl-0.3.1a-5.fc8.x86_64
jack-audio-connection-kit-0.103.0-5.fc8.x86_64

Apart from simple corrections, some wording has been slightly
changed/rearranged to facilitate paragraph formatting. These are
the only deviations from the content of the original texts at this time.

Donald,

When you are debugging add --enable-debug to your configure line.

After you finish the build, run the code using gdb...

gdb jazz

Then type "run" when you get a prompt.  When the code crashes, generate 
a back trace using the "bt" command.  Full gdb documentation can be 
found at http://sourceware.org/gdb/current/onlinedocs/gdb_toc.html

Reply back with the result of the back trace.

It will be a while before I get to it.  Maybe not until this weekend.

Pete

I wrote them, and they work, but there are extra steps required to 
generate an application on Mac OS X, and I haven't had time to learn all 
of the details.

Leland,

Can you help Donald and I out by explaining the process and maybe 
pointing out how you go about this in the Midible branch.  Donald might 
even be able to help document the existence of this branch in the Jazz++ 
web content.

Donald,

Go ahead and leave the Mac instructions as they are, and create a patch 
for the fixes you have made to the rest of the page.

TIA,
Pete

Curious...I hadn't noticed that here myself with my initial builds, however
subsequent to this call for testing....yes..there's something strange going on
with input devices on linux. Here's the detail....

My svn source version here is current at rev. 518

Distcleaned my local svn, rebuilt the source and installed (completes successfully)
The build-log is attached just in case there's something to see in it.

Started up jack/fluidsynth/qsynth as previously configured and tested okay.

Launching jazz almost immediately caused a segfault....

This is me (re)starting jazz half-a-dozen times looking for clues. On the 7th attempt ;

jazz[3310]: segfault at 1 ip 426cea sp 7fff8e2aa1e0 error 4 in jazz[400000+5ad000]


That last one 'stole' both my mouse&keyboard completely, and left me with no X input.
The system was still running though, so I moved to one of my other boxes, and
ssh'd into this system to see if there were any clues...unfortunately and AFAICT there
were no clues or errors to seen...in fact, everything looked fine...just X had lost input.


One of the last things I saw in console that launched jazz leading up to this was ;

"Invalid input device"


I believe I might have recovered the situation with an simple X restart, however I
decided to reboot the system to be sure of a 'clean slate'.

Taking Pete's obtrusion about mouse&keyboard weirdness into account, and on
a hunch thinking 'invalid input device' might be somehow related, I decided on a
different approach...

I downloaded Takashi Iwai's 'vkeybd' source, compiled & installed. I then started
this virtual midi keyboard and check it registered in alsa midi devices -- it does,
along with jack/fluidsynth/qsynth.

I then restarted jazz to discover things were actually sane again. It prompted me
for input device (I of course chose the vkeybd client), and output device (selected
qsynth)....hey presto, it's all working again as currently expected..well...caveat ;

subscribe: Operation not permitted

I see this in dmesg when jazz finishes configuration dialogs and starts.

Occasionally;

jazz[3458]: segfault at 0 ip 7f606dd1dd39 sp 7fff77552410 error 4 in libasound.so.2.0.0[7f606dc87000+d2000]

is seen in dmesg -- I'm still trying to accurately recreate this one to find the cause,
but it's being elusive...


I hope this helps some -- anything else/specific you want to know?

Just for the record, this account of proceedings here was using linux 2.6.25.3

I think my next move here is to double-check my alsalib installation - it's
been a while since I checked what's current.

So long as there are instructions on where to get it and how to build 
it, then it seems like a good plan to me.

Thx....
