19:35.55Silvrousno, and I don't think I have enough space on the Win drive for it right now
19:37.36SilvrousOh wait! sorry, apparently I have VS 2010 with C++ installed
19:38.25``Erikhm, ok, what about making a small program to  try all the SIMD levels specified in bu.h (around line 6175) as a test program to include in BRL-CAD (src/libbu/tests/bu_simd.c ?) and change the cpu on the vm image through each kind to collect the results?
19:39.03``Erikor port the function to msvc and test it to get it working on windows, or port it to clang on linux
19:39.14``ErikI'd imagine any one of those 3 options would be roughly right-sized (brlcad?)
19:40.14Notify03BRL-CAD:brlcad * 54077 (brlcad/trunk/configure.ac brlcad/trunk/doc/docbook/system/man1/en/CMakeLists.txt and 2 others): eliminate enigma from our distribution. *sniff* it's a maintenance cost that recently reared its head once again, which isn't acceptable for an interface we're not using. it's even more obsoleted as time goes by as a public domain replacement for 'crypt' considering some desktop systems can

19:41.45Notify03BRL-CAD:brlcad * 54078 brlcad/trunk/doc/docbook/system/man1/en/CMakeLists.txt: enable pictx.xml for compilation and sort the list for readability
19:44.15brlcadSilvrous: do you have access to a pentium M ?
19:44.53SilvrousNo, I only have access to Celeron and Core 2 Duo
19:45.07``Erikbochs has a significant list of cpus it can emulate
19:45.15``ErikI think qemu has a decent list, too
19:46.25brlcadso the problem that spawned the to-do entries is that a program will crash with an illegal instruction of you run an -msse program on non-sse capable hardware
19:47.59brlcadvery non-graceful at that, so we've had to disable SSE outright since the compiling host isn't necessarily the system running the binary
19:48.53brlcadso progress could be made to use that function (assuming it doesn't also cause an illegal instruction on non-sse capable hardware) to prevent run-time use of sse
19:49.03brlcadmaking sure that all works
19:50.20brlcadright now, we only compile with SSE if it's a debug build so we don't accidentally post a busted binary for people to download
20:07.59Notify03BRL-CAD:caen23 * 54079 brlcad/trunk/src/libanalyze/CMakeLists.txt: Remove reference to old test_denisty.c, now tests/denisty.c

20:22.47caen23hmm… i think i've achieved my goal of completing the 100th task
20:23.22brlcadcaen23: what do you mean? :)
20:23.35caen23ugh, nevermind, it didn't refresh properly
20:23.56caen23there are 103 task completed, i thought there were 100 and i got the latest one :D
20:24.47brlcadah, :)
20:25.19brlcadyeah, looks like "John" got #100 .. brl-cad to blender tutorial
20:39.54Notify03BRL-CAD:brlcad * 54082 brlcad/trunk/src/proc-db/CMakeLists.txt: apply a work-in-progress patch submitted by brendon jackson via e-mail, part of an independent study to create molecular geometry. this stubs main.

20:48.08brlcadcaen23: so that's a tricky one
20:48.36brlcadthe issue is related to how resources and directory entries are used/reused
20:48.40caen23i haven't compiled the example program yet, but i'm thinking reference counting?
20:49.08brlcadas a solution, perhaps but shouldn't technically need it
20:50.11brlcadthere's a few "features" in play that have to be cared for, like what legitimately happens if you dirbuild one .g file and then dirbuild another into the same database instance -- that's the method used to merge two files
20:50.15brlcad(dbconcat)
20:51.01brlcadanother is that the example program is even simpler, it's before we even have a database instance (it returns one), so we SHOULDN'T be getting duplicate geometry messages
20:51.04brlcadregardless
20:51.47brlcadthe references are apparently getting stashed on the rt_uniresource, but then that's perhaps the problem to fix
20:52.00brlcad(shouldn't be stored on the rt_uniresource!)
20:52.38brlcadcaen23: note that the example is in src/proc-db/wdb_example.c
20:52.44brlcadso you don't have to download that wiki page source
20:55.58caen23thanks for the pointers, i'll need to study librt a bit
