[Vm-beginners] Re: Fwd: Oops - I put a halt in a startup method

[Sean P. DeNigris]

The full procedure I followed was:
1. Download (from Jenkins):
  a. the cog source code from Jenkins
https://ci.lille.inria.fr/pharo/view/Cog/job/Cog%20Git%20Tracker%20(blessed)/lastSuccessfulBuild/artifact/cog.tar.gz
  b. the vmmaker image
https://ci.lille.inria.fr/pharo/view/Cog/job/Cog%20Git%20Tracker%20(blessed)/lastSuccessfulBuild/artifact/vmmaker-image.zip
2. Setup folders
  a. Unzip cog
  b. Extract the vmmaker image files (image, changes, source) to cog/image
3. Create (Smalltalk part of) hook to skip selector -
CoInterpreter>>commonSend should look like https://gist.github.com/1434823
4. Generate (Slang and CMake configuration info)
  In the vmmaker image, doIt:
	CogCocoaIOSConfig new "Cocoa Jit"
		addExternalPlugins: #( FT2Plugin );
		generateForDebug; "will be a debug build"
		generateSources; "Slang -> C"
		generate. "CMake configuration"
4. Configure (in this case for Xcode)
  a. From command line, "cd cog/build; cmake -G Xcode"
  b. For Lion: In Xcode, choose gcc as project compiler (project will be in
pwd when you did the CMake i.e. cog/build)

5. Create (C part of) hook to skip selector
  a. In Xcode, do a text search for "skipMe", which you'll find in
gcc3x-cointerp.c
  b. Replace the first branch of the boilerplate conditional to look like
https://gist.github.com/1434683 (replace selectorToSkip with your selector)
6. Build & Run
  a. Select CogVM from the "Scheme" dropdown
  b. Click the "Run" button

Your image should run normally (but slowly), skipping the requested
selector. You can even put in some breakpoints and play.
