Thank you, Jeff,

the alsa-devel-1.0.8-0 package is installed on my system, otherwise I
would have got compile errors in:
  ./configure --enable-alsa
  make

The error I was talking about, is a runtime error:
"failed to open output device /dev/dsp"
and then gwc crashes :-(

ALSA lib pcm.c:2068:(snd_pcm_open_noupdate) Unknown PCM /dev/dsp
##########################################################
audio_device_open: snd_pcm_open
No such file or directory
gwc: pcm.c:920: snd_pcm_delay: Assertion `pcm' failed.


If anyone as any idea, I will test that.

Thank you again -
bernhard

[Jeff W. <we...@ya...>]

Bernhard,

Glad you have GWC working!   You might look and see if there is an

alsa-devel-1.0.8-0 package for your system.  That
may be what you need to compile/link GWC for a native
ALSA environment.

Thank you for your persistence, and your reports to the
list, it will help others!

Sorry for spamming the list twice with my question - but after some time
I thought, my first mail was lost.

Now I've found, that gwc-playback works on my system (that means
/dev/dsp is found), if I configure & make gwc without the --enable-alsa
option.
So I can work with gwc and feel thankful for this wonderful tool.

But the question remains open for me, why the gwc alsa-option doesn't
work with my alsa-1.0.8-0 environment.
If I could be in any way helpful with testing, I'll like to do that.

Thank you,
bernhard

[Gwc-general] runtime-error with gwc-0.20-10b

[M.B. S. <mb....@ar...>]

Hallo all,

sorry for making trouble again.

Now after compiling gwc-0.20-10b (with --enable-alsa) and running under
KDE-3.3.2a with alsa-1.0.8-0 and with kernel 2.4.20-4GB-athlon
I'm getting an error, when starting to play a .wav-file:
"failed to open output device /dev/dsp"
and then gwc crashes :-(

Well, I think, first of all, gwc could handle this error and should not
crash.

Now the console shows:

ALSA lib pcm.c:2068:(snd_pcm_open_noupdate) Unknown PCM /dev/dsp
##########################################################
audio_device_open: snd_pcm_open
No such file or directory
gwc: pcm.c:920: snd_pcm_delay: Assertion `pcm' failed.


Before starting gwc I've closed down aRtsd with 'killall artds'.
All other sound-applications do work, not only the KDE-stuff, but also
gwc-0.17.6 and audicity 1.2.0-pre3 (also using /dev/dsp ).

Any help is very much appreciated,
thank you.

Hallo,

uff - suse-gnome-morass!
SuSE online-update YOU for gtk2.rpm (2.2.1-102) didn't create
/etc/gtk-2.0 with gdk-pixbuf.loaders.
A deinstallation of gtk2 and new installation (with Yast2 !) fixed this.

Now gwc-0.20-10b is complete and I'm happy - thank you!

Thank you, Jeff,

1. the fix for FFTW 2.x is fine and now I can compile gwc.
2. with the linking I got some warnings and errors, but after
deinstalling and reinstalling all the SuSE-8.2 stuff for: libgnome,
bonobo, gnome-vfs, gconf, gdk-pixbuf, pango I got a fine gwc executable
without any more linker-warnings.
3. Now the next problem is running gwc:
gwc is fine, menus are there, I can load .wav-files -
but most buttons are not visible. When starting gwc from the console
(under KDE-3.3.2a) I got the messages:
---------
(gwc:6306): GdkPixbuf-WARNING **: Can not open pixbuf loader module file
'/etc/gtk-2.0/gdk-pixbuf.loaders': No such file or directory

(gwc:6306): GdkPixbuf-WARNING **: Error loading XPM image loader: Image
type 'xpm' is not supported
---------

Now I have no dir /etc/gtk-2.0 and no file gdk-pixbuf.loaders on my system.
What I've found is a
/opt/gnome/lib/gdk-pixbuf/loaders/libpixbufloader-xpm.so and related
files. I'm using gdk-pixbuf 0.18.0-233.
Any hints are appreciated.

Thank you -

[Gwc-general] New release, and about the release numbers

[Jeff W. <we...@ya...>]

gwc-0.20-10b is on sourceforge.  Hopefully it will fix the compilation 
problems with
the fftw 2.x libs.

I stopped the current release number at 0.20-10, because the there are a 
couple of folks
working on a version that will compile for OSX as well as linux/bsd.  
While not posted, there is a gwc-0.21.x series, which will
appear when they have finished, and I'll merge back in all the 0.20-10 
stuff.

I am aware there is some problem with the help menu too.

Thanks everyone!
jw

Re: [Gwc-general] compile problem

[Jeff W. <we...@ya...>]

Hi Bernhard,

I'm going to put a fix for your problem up to sourceforge.net a little 
later.  Jeff Martin
submitted a patch which fixes the compile issue with FFTW 2.x 
libraries.  I don't have
the FFTW 2.x libs installed anymore, so if you haven't already upgraded 
to the FFTW
3.x libs, I'd appreciate it if you could hold off and test gwc-0.20-10b 
for me.

Thanks!

Re: [Gwc-general] compile problem

[Stewart E. <st...@lu...>]

This looks like a bug with gwc's support for FFTW versions prior to 3. If 
you can, upgrading to FFTW 3 would probably be the easiest fix.

Well, actually the SuSE-8.2-online update has broken my GNOME
installation. After deinstalling and reinstalling of:
libgnomeui-devel (DVD), libgnome-devel (DVD), libgnomecanvas-devel
(DVD), gtk2-devel (ftp-Update) the missing header-files were there again
and the gwc-make started Ok!

Next problem is the next compile-error in declick.c
(I'm playing with gwc-0.20-10a under GNOME-2.2.0.1).

Thank you for your help.

Thank you, Gottfried,

your question seems to go in the right direction. Well, I did install
all the (gwc) requested devel packages from the SuSE-8.2-DVD these days.
But a few weeks ago, I made my last SuSE-online update and it seems that
this update installed a new gnome file-hierarchy, because I found in
/opt/gnome2 a file named REMOVE_IN_PROGRESS:

"THIS DIRECTORY IS RENDERED OBSOLETE AND WILL BE REMOVED SOON!!!

Filesystem hierarchy was significantly changed in SuSE Linux 9.0 and
all GNOME/GTK related programs now reside in /opt/gnome.

Please move out this directory, otherwise it will be deleted by
SuSEconfig.gnome-filesystem in one week since last change.

GNOME themes can be simply moved to /opt/gnome/share/themes, all other
programs must be re-installed."

So I think, my GNOME installation is broken by these online-updates and
I have to find a way to fix it, before I can do other things, like
compiling gwc.

kind regards,
bernhard

Hi,
did you install the libgnome-devel package? Under SuSE and probably some other 
distributions, most packages have been split into a standard and a devel 
package. There might be some more missing packages. Under recent SuSE 
distribution you can use the pin comand to look for the packages which 
contain the missing files.

Kind regards,
Gottfried

Thank you, James,

well, I tried a
./configure --with-extra-includes /opt/gnome/include/gnome-1.0
didn't work.

Then I looked in the help of the configure script and tried:
./configure --includedir=/opt/gnome/include/gnome-1.0
but this didn't work too.

I've not done a gwc build recently, but most configure systems have a
--with-extra-includes option that can be used to specify
/opt/gnome/include/gnome-1.0 as an extra directory to search.

[Gwc-general] compile problem

[M.B. S. <mb....@ar...>]

Hallo,

here's a newbie question about compiling. I' using a SuSE-8.2 distro
with GNOME-2.2.0.1.
I did an untar of GWC into: /usr/local/updates/gwc/gwc-0.20-10a  .

1 ./configure was Ok
2. make started the gcc, and the in the first c-file there is a:
   libgnome/libgnome.h: file or directory not found.

   This header-file is available on my system in
   /opt/gnome/include/gnome-1.0/libgnome/libgnome.h

How to adapt the Makefile (or the configure), so that the header files
are found?

Thank you.
Kind regards,

bernhard

Re: [Gwc-general] sound only in little bursts

[Stewart E. <st...@lu...>]

Update on my odd problem.
I read somewhere (though, of course, I can no longer find the reference) 
that this card and/or driver only supported a buffer size of 8192 bytes 
(which is the fragment size). audio_device_best_buffer_size was 
returning 24576 (3x fragsize), so I tried changing it to return 
oss_info.fragsize directly - it worked now! Out of curiousity, I decided 
to check what happened when it returned 2x fragsize - that worked also.

I still don't really know what any of that means...but at least I know a 
workaround!

Curiously, the number that it freezes at is always 40960. What's the 
magic in 40960, I wonder? It's not even divisible by 42. ;-)

Unfortunately, I don't think I can.  It's one of those sawing the table 
leg situations...I changed soundcards because the one I had was junk. 
The new one is an M-Audio Revolution 7.1, which has a good reputation 
for quality sound (and so far it seems good to me). However, there's no 
support in OSS for Envy-based cards, only in ALSA. And trying to install 
the latest version of ALSA on my ancient RH9 installation was leaving me 
in dependency hell, so I installed FC3. So everything had to get changed 
at once and now my tabletop's about three inches off the ground. ;-)

Hi all,

Sorry to be late answering, I was on the road all last week.  I have to 
get my taxes filed in 2 days so I
can't spend any time digging into this right now.  As I recall, in the 
audio util section, it queries the sound
driver to find out how many bytes it can throw at the playback device.  
My first guess is that the playback
device is reporting there is no room in it's buffers, and that's why gwc 
is showing the bytes_left staying
constant.

Re: [Gwc-general] sound only in little bursts

[Joseph D. <jos...@gm...>]

Have you tried using OSS instead of ALSA?

I don't know if it will help but you changed a lot of things at once
so it might narrow down the possibilities.

Re: [Gwc-general] GWC 0.20.10 help files not found???

[Stewart E. <st...@lu...>]

Help isn't working for me either (though I must admit that I didn't try 
it until just now).
In my case, the files were actually installed into /share (for some 
reason GNOME was
blank in the Makefile). But if I move it to /usr/share/gnome/help/ , I 
still get the same error as you.

My best guess is that it has to do with changes in the configure/make 
process, since there don't seem to be any significant help-related 
changes between the two versions, but there are some configure changes 
that that could be a side-effect of. But I don't know either the gwc or 
gnome code well enough to offer a real answer.

Thanks for the suggestion.  I've been thinking about it more, though, 
and I think it's more related to gwc than I first thought.

In particular, the playback cursor moves slightly with the burst of 
sound, then stops. I placed a debug line right after the calculation of 
bytes_left inside the play_a_block function in gwc.c:

bytes_left =
        set_playback_cursor_position(&audio_view, prev_cursor_millisec);
d_print("play_a_block: bytes_left %ld\n", bytes_left) ;  /* my addition */

And I get stdout like this:
Current stack limit: 10485760 bytes
press mx:235 my:179
play_a_block: bytes_left 87224
leaving start with audio_playback=1
play_a_block: bytes_left 71528
play_a_block: bytes_left 72296
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
...

And it'll keep spewing this pretty much as long as I let it.  So it 
seems like gwc is failing to update the playback cursor position, and as 
a result not playing any more audio. I think I need to keep digging...
