Scratch

Thanks for the replies!

I have both repositories installed and have hit reload, all without success. 
Running - aptitude search scratch - does not return any package related to Scratch.
So I will try the dpkg --force-architecture and follow up with getlibs as suggested in the link. 

One problem, I need to point dpkg to the Scratch .deb file, but I do not have access to it?  Any suggestions on how to resolve this?

I tried:
dpkg -i --force-architecture scratch
but it still did not produce any results?  dpkg cannot find scratch, even though all the Launchpad sources are listed and selected in the Third Party Software tab?

So I have downloaded the installer from the Scratch site and run dpkg -i --force-architecture on it.  This has installed Scratch in Applications/Programming.  Following this, I installed the squeakvm from the repositories and changed /usr/bin/scratch from:

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

to:

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

to use the sqeakvm instead of the scratch_squeak_vm (all as suggested in Lightnin's earlier post).  Trying to launch Scratch from Applications did not produce any results.  So I changed /usr/bin/scratch back to its original form - to use the scratch_squeak_vm - and it works fine.  The only problem does seem to be with going into full-screen mode (compiz), but advice from an earlier post on this matter:

"Meanwhile, you can solve this problem on computers running Ubuntu 9.04 by selecting System > Preferences > Appearance from the main menu. Choose the visual effects tab and select "none." This will disable compiz, and solve the fullscreen repaint problem. "

does seem to solve the problem.

Thanks for all the help : )

Have someone tried using Scratch 1.4 on linux (Ubuntu 9.10) with a non-English language? Apparently the language files are there but they are not taken into account.

Yes, this is a known issue that has been fixed very recently. I hope to build and release a new version of the package later today that will solve this.

The Windows version is now available as a zip at http://scratch.mit.edu/download. We are working on getting some things (presentation mode and image effects) to compile in Linux, and creating a makefile. Eventually, we hope to have some binaries available for common linux flavors.

How about switching everything to CMake http://www.cmake.org

Otherwise, excellent idea, excellent implementation!!! Will try to use it to teach my son programming!

But.... scratch is better! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! truly true. if anyone says its worser, than cmake, they are joking

Interesting! Thanks for testing this out.

What version of Ubuntu are you using, and what version of the Scratch Package? Are there are any additional steps one needs to take to see this problem? If you could send a link to a project that causes Scratch to crash when you load it, that would be most helpful.

Thanks!

Thank you very much (cause that helped) and btw for the text diss problem i have a solution i think it appeared only after true type support was added could u plz check the code cause thats only buzzing

Hmmm.... text diss problem? Not sure I understand this one. Perhaps there is another thread about it that I haven't read....

I know this isnt the best place to share this but
i mean that the text eventually dissapears I tested scratch on my skool PC and gave it the max strain it can but the problem showed up only when i inserted awesome truetype fonts generally a new one in each costume and edited them eventually suddenly with the project size just being 2300KB the text dissapear this error i think is somewhere in the true type plugin

We hope to make Scratch work on Linux eventually but, unfortunately, it will probably not be soon. As Markus says, you can get much of Scratch to work on Linux by using a Linux Squeak VM. But a number of things don't work:

  - presentation mode (as noted)
  - image effects
  - the "note" and "drum" commands (require a MIDI package)
  - support for the (optional) Scratch Board hardware

Although it may be a while before we officially support Linux, it's great that folks like Markus can tell you how to get it (mostly) working. Thanks, Markus.

Thanks for sharing it. This one is very informative.

Hi Senorita -
Actually, that post is very outdated! Presentation mode will work, as do the image effects, and support for the Scratch board. (We've come a long way since then).

I tried it, I refused to install because it can't find "Libcario 2" even though it is installed.

Hi Mike -

Hmm, what version of Ubuntu are you using? The latest build on the PPA is only for Karmic.

Just wanted to mention that at least the basic functionality (audio record, audio playback, and simple usage) "just works" on ubuntu 9.10 (karmic) x86-64 with just:
dpkg -i --force-architecture ./scratch_1.4.0.debian.14_i386.deb

The audio playback is a bit fast, but still usable.

Kudos to the MIT folks for a linux port.

Awesome, thanks! 

I'm actually a bit surprised, since sound recording is garbled on Jaunty i386 ... maybe the 64 bit PulseAudio is different from 32? Also, do you mean the audio playback of the sounds that come with Scratch is fast, or the playback of recorded sounds is fast? If you have any info to add to this ticket, it would be much appreciated!

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

Hmm - have you tried installing the Ubuntu / Debian package from here? That's more likely to be a better solution:
http://info.scratch.mit.edu/Linux_installer
We haven't tested it on Debian, but it should work.   

If for some reason that solution isn't practical, I'll provide a little more info. The problem you are seeing above is because you aren't including links to the Scratch Plugin. Here's a copy of the startup script that installs with Debian package:

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

You'll want to replace scratch_squeak_vm with your Squeak-vm

vm-sound-PA refers to the PulseAudio plugin, which I'm not sure if Debian is compatible with. So you might try replacing that with vm-sound-ALSA or vm-sound-OSS

Please post back if you get it working, or if you have any additional questions!
