Issue 97 in cog: Sound on Linux
by cog＠googlecode.com 08 Aug '13

08 Aug '13

Status: Accepted Owner: siguc...(a)gmail.com Labels: Type-Defect Priority-Medium New issue 97 by siguc...(a)gmail.com: Sound on Linux http://code.google.com/p/cog/issues/detail?id=97 ... I had to replace the vm-sound-ALSA plugin that comes bundled in the 1.4 one-click image with the so.vm-sound-ALSA one that comes in Squeak 4.3. Couldn't we include that one by default? The one that comes with Pharo doesn't work and reports "could not find module vm-sound-ALSA". ... Looks like run-time link problems, because code we use for this plugin is same.

Issue 96 in cog: Using >> (bitShift:) instead of pow (raisedTo:)

Status: Accepted Owner: nicolas....(a)gmail.com Labels: Type-Enhancement Priority-Low New issue 96 by nicolas....(a)gmail.com: Using >> (bitShift:) instead of pow (raisedTo:) http://code.google.com/p/cog/issues/detail?id=96 By virtue of SLANG translation, interpreterAllocationReserveBytes uses pow((double)2,(double)n) to answer an int, wouldn't it better to just use a bit shift? 2^n <=> 1<<n, up to n=31 I doubt we reserve more than that, the result is signed anyway. And this would remove yet another warning. Attachments: interpreterAllocationReserveBytes.st 2.0 KB

Re: Issue 72 in cog: Don't open an Dialog on Mac in headless mode

Updates: Status: Accepted Cc: esteba...(a)gmail.com Comment #1 on issue 72 by sean.p.d...(a)gmail.com: Don't open an Dialog on Mac in headless mode http://code.google.com/p/cog/issues/detail?id=72 This is even more important now with the MBP retina. A "headless" cog image always forces the GPU to discrete mode, draining the battery. I often use headless (e.g. for Jenkins jobs and web scrapers) and in addition to the distraction of the unneeded window popping up, the switch to the power hogging GPU for no reason is even more of a drag.

Accelerating LargeIntegersPlugin phase 2
by Nicolas Cellier 29 Mar '13

29 Mar '13

I published code on SmalltalkHub (nice occasion to test it, and I did not want to pollute source.squeak.org with experimental) in sync with .oscog branch. MCHttpRepository location: 'http://smalltalkhub.com/mc/nice/NiceVMExperiments/main' user: 'nice' password: '' I also blogged about it http://smallissimo.blogspot.fr/2013/01/update-on-squeak-largeinteger-32-bit… I didn't take any care to make the code 64bits friendly. This will require a review... Nicolas

Compiling Newspeak Cog VM on Ubuntu 12.10 64bit
by Philipp Tessenow 14 Mar '13

14 Mar '13

Hi, I am trying to compile the Newspeak Cog VM on Ubuntu (12.10) 64bit, but fate is not on my side ;) I'd higly appreciate any help, so here is my story: The VM seems to compile correctly, but the newly build nsvm binary complains about a missing vm-display-X11 plugin. Using strace, as suggested here (http://forum.world.st/Cannot-load-vm-display-X11-module-after-build-from-la…) shows, that nsvm actually finds vm-display-X11: <code> ... open("/home/philipp/stud/masterarbeit/build/squeak/nscogbuild/unixbuild/bld/../../../nsvmlinux/lib/nsvm/4.0-/vm-display-X11", O_RDONLY|O_CLOEXEC) = 3 ... open("/usr/lib/i386-linux-gnu/libX11.so.6", O_RDONLY|O_CLOEXEC) = 3 ... open("/usr/lib/i386-linux-gnu/libxcb.so.1", O_RDONLY|O_CLOEXEC) = 3 ... open("/usr/lib/i386-linux-gnu/libXau.so.6", O_RDONLY|O_CLOEXEC) = 3 ... open("/usr/lib/i386-linux-gnu/libXdmcp.so.6", O_RDONLY|O_CLOEXEC) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\240\16\0\0004\0\0\0"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0644, st_size=21888, ...}) = 0 mmap2(NULL, 24692, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xfffffffff7198000 mmap2(0xf719d000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x4) = 0xfffffffff719d000 close(3) = 0 mprotect(0xf719d000, 4096, PROT_READ) = 0 mprotect(0xf71a1000, 4096, PROT_READ) = 0 mprotect(0xf71c3000, 4096, PROT_READ) = 0 mprotect(0xf72f7000, 4096, PROT_READ) = 0 munmap(0xf72fb000, 108384) = 0 munmap(0xf71c5000, 1268568) = 0 munmap(0xf71a3000, 135468) = 0 munmap(0xf719f000, 12424) = 0 munmap(0xf7198000, 24692) = 0 stat64("/home/philipp/stud/masterarbeit/build/squeak/nscogbuild/unixbuild/bld/../../../nsvmlinux/lib/nsvm/4.0-/vm-display-X11.so", 0xffe7562c) = -1 ENOENT (No such file or dir ectory) ... </code> Unfortunately, after finding vm-display-X11 and loading some additional libraries nsvm aborts and continues searching for other vm-disply-X11 plugins elsewhere. ldd gives the following output (which seems to be OK for me): <code> ldd /home/philipp/stud/masterarbeit/build/squeak/nsvmlinux/lib/nsvm/4.0-//vm-display-X11 linux-gate.so.1 => (0xf77d0000) libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf776d000) libX11.so.6 => /usr/lib/i386-linux-gnu/libX11.so.6 (0xf7637000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf748c000) /lib/ld-linux.so.2 (0xf77d1000) libxcb.so.1 => /usr/lib/i386-linux-gnu/libxcb.so.1 (0xf746a000) libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf7465000) libXau.so.6 => /usr/lib/i386-linux-gnu/libXau.so.6 (0xf7461000) libXdmcp.so.6 => /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0xf745a000) </code> Reading the unixbuild/HowToBuild file I found the following: <cite> Testing an external plugin has completely linked ------------------------------- You may find that an external plugin compiles and links but does not load.

For my unexperienced eyes this looks like libX11.so cannot find xcb, albeit I installed every x11/xcb library I can think of (to name them: libx11-xcb-dev:i386, libx11-xcb1:i386, libx11-6:i386, libx11-dev:i386, xcb-proto:i386, xcb:i386, libxcb1:i386, libxcb1-dev:i386). I also tried the above steps on a Ubuntu 12.10 32bit VM with similar results. Am I missing something? Do I need a special setup to compile a CogVM? Any other ideas? Thanks, Philipp
