Instability
by Overcomer Man 12 Sep '11

12 Sep '11

When trying to measure a method from a fileIn by adding single quotes and using size, the workspace somehow got into a state where it would generate errors whenever I simply put the mouse into the workspace. How does one fix such things so as to guarantee it never happens when deploying an application? Is there a way to make Smalltalk as stable as a C, C++ application?

Bug In VideoFlow.st
by Overcomer Man 11 Sep '11

11 Sep '11

After several steps including adding FFI, I'm still stuck on the Video package. I tried to manually fileIn VideoFlow.st but that failed. Error: 'genBranchPopFalse: distance index 1133 is out of range 0 to 1023' I also tried contacting people listed as developers and maintainers of the package with no result. The ones who responded say they had nothing to do with it but their name got put on it. What is the next step? Thanks.

FFI in Cuis
by Overcomer Man 10 Sep '11

> You should use the http://source.squeak.org/FFI Monticello repository to load FFI. Load FFI-Pools first, then FFI-Kernel. Optionally you can load the platform code for your OS (FFI-Win32 if you're using windows) and the tests (FFI-Tests). If you don't want to bother with doing this manually, then you can use SqueakMap or there's the "Extending te system" item in the docking bar's Help menu. The second code snippet loads FFI. > > Levente It worked, thanks! I backtracked on the releases until I found one that would compile for each group. FFI-Pool3, FFI-Kernal22, FFI-Win8, FFI-Test4 I also tried FFI-Examples-Win32 after removing the Mac and X11 classes but it failed. The working code compiled the example method getFocus. Then I tried to manually fileIn VideoFlow.st but that failed. Error: 'genBranchPopFalse: distance index 1133 is out of range 0 to 1023' Is there something I can safely fix or ignore here? How do you copy the debug walkback into an email? Thanks, Kirk

OpenGL-Tutorial updated
by Lawson English 09 Sep '11

09 Sep '11

I added a couple of minor bits to my ongoing implementation of the HE OpenGL tutorials. Only 2-5 are available right now. http://croquet-src-01.oit.duke.edu:8886/Contributions' OpenGL-Tutorial-LDE.10 I added a timer option ala the OpenGL class>>example, basically. To run, as is: myOGLView := OGLMorphTutorial new. myOGLView openInWorld. myOGLView toggleTiming. "on" myOGLView toggleTiming. "off" Currently it only runs Lesson 4. To change this, edit #renderScene to use one of the other tutorials available. I'll add an option to provide a choice of which lesson to run, eventually. You can also use it as a template for your own experimentation with OpenGL. Lawson

How to make FFI work?
by Overcomer Man 09 Sep '11

09 Sep '11

FFI - Foriegn Function Interface example given at http://wiki.squeak.org/squeak/2422 fails to compile under a test class, so it can't work. The error is expecting a '>' which implies the apicall is wrong. Since it's example code, it's likely correct and the parser is not working. I assumed it was a failure of FFI to be installed properly in Squeak 4.2 All-In-One. I tried the FFI install .st which gave an error about an unrecognized password. (I have since been unable to locate that code to put the error and link in this post.) This is confusing since the FFI .dll comes with the All-In-One so it must be used somewhere. Any suggestions? Getting FFI code to accept is needed in my attempt to load the old video package or try openCV.

Universe Video .sar to FileIn
by Overcomer Man 07 Sep '11

07 Sep '11

I tried Squeak Universe, Uncategorized Video and Image Processing but it failed to load. I attempted to contact Maintainer Lex Spoon asking for an update but no response so far. I downloaded the .sar file indicated but it's not a fileOut so I can't read and learn to fix it. What do I do with the .sar file so I can read and install the Smalltalk code class by class? Thanks, Kirk Fraser
