Hi guys!<br>
<br>
In the past few days i tried to get InterpreterSimulator running without<br>
success.<br>
First of all, a little context about my goal: I'm digging into the VM<br>
because i would like to be able to delegate to some class (that I'll<br>
develop) the responsibility for, say, the method lookup algorithm.<br>
<br>
With that in mind, here's what i've been doing:<br>
Using the Pharo 1.2 image Mariano Peck's prepared in his exellent article<br>
(<a href="http://marianopeck.wordpress.com/2011/04/23/how-to-debug-the-vm/" target="_blank">http://marianopeck.wordpress.com/2011/04/23/how-to-debug-the-vm/</a>), loaded<br>
the VMMaker package with the following script:<br>
<br>
Deprecation raiseWarning: false.<br>
Gofer new<br>
squeaksource: 'MetacelloRepository';<br>
package: 'ConfigurationOfCog';<br>
load.<br>
(Smalltalk at: #ConfigurationOfCog) project latestVersion load.<br>
<br>
Once it finishes (without errors) I "Save As" the current image as<br>
"demo.image", close it and open the original Pharo 1.2 image that Mariano<br>
provided.<br>
When, for example, I run:<br>
<br>
(CogVMSimulator new openOn: 'demo.image') test<br>
or<br>
(InterpreterSimulatorLSB new openOn: 'demo.image') test<br>
<br>
I get the following error: "Error: basicNew: failed" (see attached images at<br>
the end).<br></blockquote><div><br>Weird. Something I remember about the simulator is that you need to run it with a VM that has the BochsIA32Plugin. Try Eliot's VM that will have it for sure. But anywya, I doesn't look related to your particula problem. <br>

When I tried to load VMMaker in the Pharo 1.3 OneClick release, I got<br>
another error (see attached images at the end).<br>
<br></blockquote><div><br>Yes, because you need some changes in order to make it work. I have attached those changes in the post. But those changes should be already integrated in latests Pharo 1.3.<br>You don't have that error in the image I put of 1.2 because that image comes already with such changes. <br>

Am I doing something wrong?<br>
Are those the right simulators to use? I can tell the difference between all<br>
that are available in VMMaker package.<br>
<br></blockquote><div><br>Well...it depends on what you want. FOr example, if you build a stack VM then you should use instead StackInterpreterSimulator. So..for the Cog VM I guess it is CogVMSimulator.<br><br>If you go to here: <a href="http://www.squeakvm.org/svn/squeak/branches/Cog/image/">http://www.squeakvm.org/svn/squeak/branches/Cog/image/</a><br>
you can see <a href="http://www.squeakvm.org/svn/squeak/branches/Cog/image/VM%20Simulation%20Workspace.text">http://www.squeakvm.org/svn/squeak/branches/Cog/image/VM%20Simulation%20Workspace.text</a><br>It might be outdated, but it can be a start point.<br>
<br>cheers<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Thanks in advance!<br>
