3.9-7 for Solaris SPARC (problems)
by Andreas Wacknitz 27 Jul '06

27 Jul '06

Hi all, I have successfully compiled SqueakVM-3.9-7 for Solaris 10 (SPARC). But there were some problems I want to write about. First, some background: - For the compilation I have been using Sun's OpenSPARC Cool Tools (http://cooltools.sunsource.net/gcc/index.html). That is a gcc-4.0.2 frontend and SunStudio's backend. This combination creates 2 to 3 times faster code than a regular gcc (my own micro benchmarks). - I run configure --prefix=/opt/squeak as the default /usr/local is inappropriate for System V. - Furthermore I used CGLAGS="-O2 -fast" ("-O3 -fast -xipo" had problems). - It was necessary to use gmake instead of make due to some incompabilities. I had to correct the source code at four places: 1. .../platforms/unix/vm/aio.c: System V doesn't know of O_ASYNC. Thus, I had to remove this flag in aioEnable(int fd, void* data, int flags). I don't know whether there is an equivalent for System V. Furthermore, I don't know whether this will be a problem in the resulting executable. 2. .../platforms/unix/vm/sqUnixMain.c: PATH_MAX needs an #include <limits.h> 3. .../platforms/unix/vm-sound-Sun/sqUnixSoundSun.c: static int soundAvailableSpace(void) needs a forward declaration because of the "static" modifier. 4. .../platforms/unix/src/plugins/UnixProcessPlugin/UnixProcessPlugin.c: feof() needs an additional cast. Thus, if ((feof(sqFile->file)) == 0){ gets if ((feof((FILE *)(sqFile->file))) == 0){ The resulting installation runs fine with two remaining problems: 1. Running squeak I get many "iconv_open: Invalid argument" messages on the console. 2. Some UNIT tests fail: running "Tests-VM : FloatMathPluginTests" gives "27 run, 18 passes, 0 expected failures, 2 Failures, 7 errors, 0 unexpected passes" failures: #testFraction #testTan errors: #testArcCos #testArcCosH #testArcSin #testArcSinH #testArcTanH #testLog #testLog10 All the errors are due to "primitiveFailed". I did these tests in an 3.9-7048 image. Interestingly, running the same tests in the same image on Windows (VM-3.7.1) results in "27 run, 7 passes, 0 expected failures, 0 failures, 20 errors, 0 unexpected passes". So, is FloatMathPlugin broken on all VMs and how to get rid of the annoying warning messages on the console? Regards, Andreas

Re: Fwd: vm-dev moving to lists.squeakfoundation.org

Ok, the list has moved over....

(The mails where just swallowed, not even a failure-message...). I'm of course more than willing to hand over the mainainership back to the original maintainer. Who was it? Marcus

One-click plugin development
by Bert Freudenberg 10 Jul '06

10 Jul '06

I found myself doing this a gazillion times over the last days: click the VMMaker's "generate plugin" button, switch to XCode, invoke the plugin build, switch back to Squeak, unload the plugin to test the new one. No more. A few lines of code automate all of this: VMMaker>>generateExternalPlugins ... externalPlugins size = 1 ifTrue: [ | result | logger show: 'XCode: building ', externalPlugins first, ' ... '. result := Applescript doIt: 'tell application "XCode" to build'. logger show: result; cr. (result beginsWith: '"Build succeeded') ifTrue: [Smalltalk unloadModule: externalPlugins first] ifFalse: [Applescript doIt: 'tell application "XCode" to activate']]. Now I just click "generate plugin" and debug on. Life is bright again. Except for the occasional crash, of course :) - Bert -

Mac build setup?
by Andreas Raab 07 Jul '06

07 Jul '06

Hi John - I need to do a bit of work with a custom Mac VM and I was wondering what setup you use these days to build VMs. Is there any document somewhere that describes your setup, steps to take etc. to build a Mac VM? Thanks, - Andreas

[FIX] lockSurfaces
by Bert Freudenberg 07 Jul '06

07 Jul '06

There is a wrong condition in an almost never-taken branch of BitBltSimulation>>lockSurfaces (when src=dst): isWarping ifFalse:[ "When warping we always need the entire surface for the source" sourceBits _ self cCode:'fn(sourceHandle, &sourcePitch, 0,0, sourceWidth, sourceHeight)'. ] ifTrue:[ "Otherwise use overlapping area" l _ sx min: dx. r _ (sx max: dx) + bbW. t _ sy min: dy. b _ (sy max: sy) + bbH. sourceBits _ self cCode:'fn(sourceHandle, &sourcePitch, l, t, r-l, b-t)'. ]. As the comments indicate, the condition is reversed. Please include attached fix in VMMaker. - Bert -

newbie trouble building Squeak VM on Mac
by Michael Haupt 03 Jul '06

03 Jul '06

Hi, it's my first attempt ever to actually build a Squeak VM, hence the crosspost to both the beginners' and VM dev lists. I have checked out the latest VM sources from svn today, run the configure script (for the unix platform - I have a G4 PowerBook running Mac OS X 10.4.7), and issued "make Squeak.app". Eventually, the build stops with an error: /Users/haupt/squeakvm/squeak-svn/platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.h:26:7: error: #error *** cannot find gl.h Huh. Apparently the configure script thought there was OpenGL on the machine, didn't it? Anyway, where / how can I obtain that file or exclude OpenGL support? Thanks in advance, Michael
