Adrian's blog; last part
by Chris Cunnington 08 Dec '10

08 Dec '10

Thank you for that great answer. I've printed it out, read it, and I'll read it tomorrow. I have to stop for today, as its all starting to become keleidoscopic. I'll make a comparison with /platform/iOS/vm/src/vm/interp.c. It's one thing to follow a blog, but I'd say my real education about VM building starts with looking at this problem. I imagine I can try substitution of file(s) from the other sources. I filmed the whole thing. Edited it comes in at about six and a half minutes. That it ends with a car crash is probably a plus. I'll put it up Monday with a link to Adrian's blog. Chris

VM Version
by Gabriel Hernán Barbuto 08 Dec '10

08 Dec '10

Hi I've asked John how do I know from the VM version string of the Mac VM which VMMaker version and platform sources version was used to build the VM. Below is his response. Cheers Gabriel In the 90's and early part of 2000 all the source code to build the macintosh VM and to run VMMaker actually was in the image. So when you asked for the vmVersion the string you got back "Squeak4.1 of 17 April 2010 [latest update: #9957]" which told you every you needed to know since the image was tied to the vm development. When I made adjustments to the VM that was actually pushed to the update stream for inclusion in everyone's image. This changed when we decoupled VMMaker from the image, but unfortunately we did not consider how that affected the vmVersion string since as you see it actually does not say which version of VMMaker was used. Now the Squeak VM 4.2.5b1 comes from the bundle information string found in info.plist, but anyone can change that. The other vm version info is via 1006,1007,1008 where for 1006 we return a unique string that the vm builder has to update. This was Andreas idea to have something that could identify the VM version so an image could decide if it was certified to run on a particular VM.. I decided to return the fact it was a macintosh VM, which platform type which would be Carbon or Cocoa now, the version number, the date it was created and the UUID of the machine it was built on. if (id == 1006) { return "Mac Carbon 4.2.5b1 15-Jun-10 >85D9C693-2A2A-4C33-B05C-C20B2A63B166<"; or in the 5.x series case 1006: {/* vm build string also info.plist */ #if (SQ_VI_BYTES_PER_WORD == 4) #if STACKVM return "Mac Cocoa Cog 5.8b12 21-Sep-10 >1B0534FA-246C-47C5-AB29-7A76C81CCDCB<"; case 1007: { /* vm build string also info.plist */ #if STACKVM extern char *__interpBuildInfo; return __interpBuildInfo; #endif break; } case 1008: { /* vm build string also info.plist */ # if COGVM extern char *__cogitBuildInfo; return __cogitBuildInfo; #endif break; } I note that Eliot did resolve the issue by returning 1007, 1008 that shows the vmmaker build info for his COG fork. Now in order to decide what VMMaker source to use. I'm afraid you have to look at the SVN data, In general my process was to update the image used for VMMaker to the current VMMaker on the date of the build, then after it was shown to be a viable VM, I would check in all my changes. See for example #2213 "Mac Carbon VM 4.2.5b1 Update FFI plugin to latest code base. Bring other code base up to VMMaker-jcg.182" or #2158 "64bit work merging from V5 Macintosh Cocoa Squeak VM microsecond & utc clock updates Mac Carbon 4.2.4b1" or #2156 "Mac Carbon 4.2.3b1U VMMaker 160. MicroSecond clock, compiler warning fixes" Sometimes I would include the version info for the vmmaker used. For earlier builds sometimes I would keep a copy of the source code and vmmaker output as an archived file. Those files are part of various GB of folders that I sent Esteban.

How to inspect variables while debugging SqueakVM?
by Mariano Martinez Peck 08 Dec '10

08 Dec '10

Hi.sooo...I am debugging all the C code with XCode. I can put breakpoints inside interp.c and stop there...etc. Now, for example, I put a breakpoint in somewhere inside the funcition sqInt lookupMethodInClass(sqInt class) { and I would like to see for example, which is that class. Of course, since thats a OOP, in XCode I see a address, a number. And the same with messageSelector insVar, and the rest. Now...how you usually debug this? how can I know the real Smalltalk class of that address? and messageSelector? I guess there should be a way to do this in C/XCode. Thanks! mariano

Adrian's blog instructions; part 1
by Chris Cunnington 08 Dec '10

08 Dec '10

Well, that's got it. I'm in section 3 now. I installed the XCode (which I thought I had) and checked with "man gcc" and "man make". The "configure" command and then "make" created the vm binary. I proceeded with a new Squeak image. I tried it on a Pharo image too. No problem. The ConfigurationOfVMMaker loaded the tool; I've opened it in the World; and backed up the src file. It's come this far, so I figure the rest will be pretty straightforward. I'll do the next parts tomorrow. Cool tutorial. Chris

Yea, it seems I have no response to "man gcc" or "man make". I thought I had the XCode installed, because I've used the XCode app. Something's up, so I'll take a step back. Chris

Adrian's blog instructions; part 1
by Chris Cunnington 07 Dec '10

07 Dec '10

Hi, I've printed out Adrian's instructions from his blog. I've followed along, but my knowledge of cmake and make isn't great. I do know I have cmake --version 2.8.0 installed. I've built the directories and executed: $ sudo ../unix/cmake/configure --without-RomePlugin --without-vm-display-Quartz Password: from within /build. I get: -- Configuring squeak 3.11.3-2151 for i386-apple-darwin10.5.0 -- Using source directory ../unix/src CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly. Missing variable is: CMAKE_C_COMPILER_ENV_VAR CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly. Missing variable is: CMAKE_C_COMPILER CMake Error: Could not find cmake module file:/Users/chriscunnington/Desktop/vmbuilding/platforms/build/CMakeFiles/CMakeCCompiler.cmake CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.

I've got the tools. I have the files. I'm in the right place. Does this error mean it's expecting a file called Makefile in the /unix/src directory? Any help would be greatly appreciated, Chris

How to make a debug build of the VM?
by Gabriel Hernán Barbuto 06 Dec '10

06 Dec '10

Hi I am using the OS X VM and I want to rebuild it with debug information. I am assuming that the version I downloaded doesn't contain debug information. I want to build a specific version. If I print Smalltalk vmVersion I get: 'Squeak4.1 of 17 April 2010 [latest update: #9957] Squeak VM 4.2.5b1' I am not sure how to relate this with VMMaker version and SVN revision. Thanks in advance. Gabriel
