I've just tested Miriam's excellent scratch package on 64 bit Maverick. https://launchpad.net/~miry/+archive/scratch
Install goes very smoothly! However, sound playback and recording show the same errors we had been seeing over the past few years when using OSS / or ALSA on Ubuntu. I also tried using the pulse plugin, and it gives me a segmentation fault when playing a sound: Executing: /usr/lib/squeak/4.0.3-2202/squeakvm -encoding UTF-8 -vm-display-x11 -xshm -plugins /usr/lib/scratch/Plugins/:/usr/lib/squeak/4.0.3-2202/ -vm-sound-pulse /usr/share/scratch/Scratch.image Segmentation fault 10280100 [] in SoundPlayer class>playLoop 10268900 Semaphore>critical: 10268808 SoundPlayer class>playLoop 10279796 [] in SoundPlayer class>startPlayerProcessBufferSize:rate:stereo: 10279888 [] in BlockContext>newProcess Aborted I'm not sure if this is because of the issues that John has mentioned earlier (current version of Scratch.image depends on old Squeak sound primitives), or a different issue with the pulse plugin code. I recall that we'd had some trouble with the version of the pulse plugin that was included with Squeak, and instead had been including a binary that Derek O'Connell had given us some time ago. Another question to anyone out there (I apologize in advance for my noobishness when it comes to packaging). If we incorporate Miriam's changes into the official scratch package, will it be possible to create a single binary install package for 32 and 64 bit systems that includes the separate scratch-plugins package? I suspect many end users don't know how to add a repository or resolve dependencies. So I wonder if there is some method of creating a single one-size-fits-all package for us to put on our download page (trusting that the package manager will manage to find the Squeak-vm, since that's already available in the repositories). -Amos On Thu, Mar 17, 2011 at 6:39 PM, Derek O'Connell <[email protected]>wrote: > On 17/03/11 21:12, Miriam Ruiz wrote: > >> 2011/3/16 Derek O'Connell<[email protected]>: >> >>> Hi Miriam, >>> >>> just out of interest, how is audio recording (via Scratch) working for >>> you >>> on your 64bit platform?
