Kill current process from gdb?
by Sean P. DeNigris 28 Jan '12

28 Jan '12

What (if anything) can I do from a debug VM (via gdb?) to kill the currently executing Smalltalk process? Thanks.

(Resend) Where to get current code destined for "official" Unix Squeak VM?
by David Corking 20 Jan '12

20 Jan '12

Hi, this may be an FAQ or I may just have overlooked something obvious. The reason I got confused is that some vm-dev posters seem to use sources from the Cog project's gitorious repository to build Stack VMs on a Jenkins server, and yet http://squeakvm.org/unix/ links to a subversion repository : 1. Which is the current tarball for building official VMs for unix? (Is it http://www.squeakvm.org/unix/release/Squeak-4.4.7.2357-src.tar.gz ?) 2. Which is the source code repository for the current Unix Squeak VM code (in case I need to suggest a patch) ? (Is it http://squeakvm.org/svn/squeak/trunk or https://git.gitorious.org/cogvm/blessed.git ?) 3. Which Squeak image contains the current SLANG source code to emit VM C sources? (I guess Squeak Trunk, that is http://ftp.squeak.org/4.4/Squeak4.4-11860.zip with updates from the trunk repository in Monticello. Again, in case I need to submit a patch.) David (p.s. I need sources in order to figure out if I can get all the x86_64 plugins working. There are no official builds I know of for x86_64, and the Fedora koji build system suggests to me, if I read the koji output correctly, that there is some unintended bitrot in Fedora's 64 bit support for squeak.)

Error while compiling
by Guillermo Polito 12 Jan '12

When I compile the last version of the Vm in my 32bit ubuntu, I get the following: In file included from /home/guille/Dev/Pharo/cogvm/coglinux/blessed/platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:30:0: /home/guille/Dev/Pharo/cogvm/coglinux/blessed/platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.h:13:16: error: redefinition of ‘struct glRenderer’ /home/guille/Dev/Pharo/cogvm/coglinux/blessed/platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.h:6:16: note: originally defined here Diving into the code, I found that in sqUnixOpenGL.h there is code like: ... typedef struct glRenderer { int bufferRect[4]; int viewport[4]; int used; void *drawable; void *context; } glRenderer; #if defined(USE_X11_GLX) || defined (USE_QUARTZ_CGL) # define GL_RENDERER_DEFINED 1 # define MAX_RENDERER 16 # if defined(HAVE_GL_GL_H) # include <GL/gl.h> # else # if defined(HAVE_OPENGL_GL_H) # include <OpenGL/gl.h> # else # error *** cannot find gl.h # endif # endif #endif ... Shouldn't the typedef be written inside the #if and #endif? If so, how do I publish the fix? Cheers, Guille

Fwd: Oops - I put a halt in a startup method
by Sean P. DeNigris 10 Jan '12

From http://forum.world.st/Oops-I-put-a-halt-in-a-startup-method-td3800163.html : My image appears for an instant and then crashes. Is there any way to recover from this? I made some progress, but I'm not sure I'm on the right track... I built a debug VM and found primitivePerform, which is apparently called by the following: FeaturesDB perform: #startUp: with: resuming How will I know which call to skip/break on? Maybe there is there a way, from the VM side, to get the receiver class name as a string? If I knew that the receiver was FeaturesDB, that would be the one... And then once I have the right call, can I just skip over it?
