hello,
while opening scratch in debian 5.0 using
$ squeak Scratch.image

i cannot use many features of the software:
- save, save as
- choose new sprite from file
- import project
- export sprite
and many many others;
is there any way to get away from all these issues ?
when these errors appear, a debugging pink window pops out with this title:
"message not understood: findTokens:"

and a whole bunch of errors which i do not understand and, unfortunately i cannot past them here


thank you very much in advance

Sounds like a problem with directory permissions?

The script just saves time / typing. It launches squeak with the correct arguments necessary to run Scratch. So you can just try:

squeak -plugins /usr/lib/scratch/Plugins -vm-sound-PA /usr/lib/scratch/Scratch.image

1. - plugins tells squeak where to look for Scratch plugins. The reason you can't save, etc. is b/c your squeak doesn't have access to the plugins that Scratch needs, especially ScratchPlugin. You can get them from the Ubuntu PPA linked to from the Linux Installers page.

2. -vm-sound-PA tells squeak to use the PulseAudio plugin to play sound. You might not have PulseAudio, so instead you could try -vm-sound-ALSA .

Good luck!

Where I can receive a source code of -vm-sound-PA?


PS: Sorry for my english

Check out the source code repository mentioned here:

Ah, the pulse plugin we use has a few bugs as well, unfortunately. I think it is probably the same version as you've found on the Squeak site.

The Pulseaudio sound libraries seem to be a moving target for developers. So the plugin we had worked great on Jaunty, but on Karmic there are problems with recording. If you'd like to help contribute a fix, or perhaps work on a GStreamer plugin, we'd love the help!

All right, I am kinda getting steamed up right now.

Scratch Team says "blah blah blah blah", it's not helpful.

I'd like a straightforward list of steps on what I need to do on 64-bit Ubuntu Karmic Koala linux operating system using the PPA.

I unsure wether I need to update the key in 9.10 or 9.04.

I'm sorry, the instructions are just kinda badly built. I sound really mad, don't I?   

I'd still like it soon, because all my computer skills in Windows and Mac don't apply in Linux.

And please don't say "Go to Windows, it's easier" because I am USING LINUX and that is that.

Thanks.

The thing is, I don't have an i386 architecture- I have an AMD 64-bit! That's my problem. I was wondering, aren't 64-bit systems backwards compatible? I thought that would be the case with Ubuntu Linux 9.10, but not. Maybe I should just download a 32-bit Ubuntu version?

I did try the 64-bit force, though. It worked!    Thanks!

At the time i'm using Ubuntu Linux too. My windows 7 computer broke down so..... yeah.

I hate how the applet doesn't play sound on linux. How annoying!

there was no problem with eeepc901 (eb4 beta) and 1.4, it worked fine ; but i have reinstalled my system and now, the scratch 1.4.0.1 ask for a pulseaudio >= 1.0.9... but this pulseaudio does not exist (higher is 0.9.21-1)

What I know about the Eee PC which I do not know that much about, tells me that you may not be able to run scratch on it.

To my knoledge, it comes with the OS Sugar, which scratch can not be used on.

If you want scratch on Eee PC, I'd suggest getting Linux Ubuntu or Debian.

I put this command and ...

/scratchv2$ squeak -plugins /usr/lib/scratch/Plugins -vm-sound-PA /usr/lib/scratch/Scratch.image


i have this message

thanks a lot

Thought I would post this in case others ran into the same problem.

Just installed Scratch on a 32bit Ubuntu system (10.04) and noticed that the audio playback had a bit of a delay.  Read this in the README.txt:

       The "scratch" startup script shows how to execute the vm, and
       the necessary command line switches to indicate where the
       plugins can be found, and which sound plugin should be used.
       The included script uses the pulseaudio sound plugin by
       defauilt, but plugins are also available for alsa and oss -
       simply change the vm's command line switches to try different
       ones. Here's the script:

       /usr/bin/scratch_squeak_vm \
       -plugins /usr/lib/scratch/Plugins \
       -vm-sound-pulse \
       /usr/lib/scratch/Scratch.image "${@}"

Changed from the default pulse plugin to OSS and the problem was solved.

The sound and midi problem in Scratch for Linux - next step:

1. Disable PulseAudio - not support on current version squeak-audio

2. Disable a sound server arTs (or use artsdsp in Scratch startup script)

3. Use startup script for the TiMidity ALSA sequencer interface (best variant -timidity automatically starting on boot system) or manual run timidity as midi-server (from root or sudo - very bad idea):

timidity -iADq -Os

Write this script and save as "midi_support". Set execute permission for this script.

#!/bin/sh
## MIDI support for Scratch

if egrep -q 'TiMidity' /proc/asound/seq/clients 2>/dev/null;
    then
## loop, if squeak running
    while ( ps -A | grep 'squeak' >/dev/null ); do   
## if Squeak midi port exist?
        if  ( aconnect -i | egrep -q 'Squeak' >/dev/null);
        then
             if ! egrep -q 'Connecting To: 128:0' /proc/asound/seq/clients 2>/dev/null
                then aconnect Squeak:0 TiMidity:0
             fi
        fi;
    done
    else echo "TiMidity server not run"
fi       

4. Run Scratch startup script.
6. Run 'midi-support' script
7. Selecr language interface for Scratch (!!!) for creating MIDI-port (???)
8. Test: play sound, sound record and midi work fine.

My startup  script for run Scratch:

/usr/bin/artsdsp /usr/share/Scratch/squeak/squeak -plugins /usr/share/Scratch/squeak /usr/share/Scratch/Scratch.image &


Scratch.image for Scratch1.4 Beta7 (works and in the previous versions).
Squeak - squeak-3.10-1.

My Linux: Mandriva 2009 (KDE 3.5)

Hi,

I have installed Scratch in Ubuntu 10.04 amd64 using the "--force-architecture" flag. It seems all OK, but the "play drum" and "play note" blocks are not working properly: they play always the same sound at different tone, regardless instrument or drum number. I have tried to follow your steps, but the "aconnect -i" command don't display any Scratch or Squeak midi port. Timidity is running correctly as daemon. Apparently, the strange seventh step is not working for me.

Any help, please?

Unfortunately, we were never able to get midi working properly with Scratch on Linux.    Sorry about that!
