04:13.21 hcurtis Hi, everyone. To create a patch file, I am entering "svn diff bad.c corrected.c > myPatch.patch", but the patch file it creates is empty. What am I doing wrong?

15:03.10 brlcad drv_: it means that implementation from 2012 is either unreviewed or flawed
15:03.36 brlcad so you could review it, clean it up, see if it works as described, maybe make a test case for it
15:03.41 brlcad that would be a useful patch

15:22.47 brlcad todor_nikolov: I've heard a comment saying there is a problem, but I still have no information about what that problem is or what was tried ... so it's kind of impossible to help without more information, no? :)
15:23.04 todor_nikolov I am building and sending the log into a file

15:25.05 ankesh11 brlcad: Wanted to discuss about the issue of incorporating the Benchmark website using a MediaWiki extension.
15:25.36 ankesh11 Would it be hard to deploy a subdomain to a mediawiki independent setup?
15:26.40 brlcad ankesh11: not sure what you mean
15:26.47 brlcad it's easy to create a new subdomain

15:27.10 brlcad todor_nikolov: would you use a different pastebin?

15:27.52 ``Erik something killed ld or something, remove the libtk.so.8.5 file and try building again
15:28.32 ankesh11 That's right, I mentioned that earlier too. hsrai suggested we should deploy the benchmark website using mediawiki, as it would use the current infrastructure. I am of the opinion leveraging mediawiki would not be useful in this case.

15:31.06 brlcad ankesh11: I think you should write a proper cost-benefit matrix comparing mediawiki with laravel (or whatever) if your proposal is selected
15:31.24 todor_nikolov It says the file does not exist
15:31.27 brlcad I'd like to see what the tradeoffs are before deciding that bit of critical architecture
15:31.48 brlcad todor_nikolov: it does not say that
15:32.04 todor_nikolov rm: cannot remove `libtk.so.8.5': No such file or directory
15:32.07 brlcad it says it DOES exist .. but that it's invalid (truncated, too short)
15:32.29 brlcad you're issued rm on the wrong path
15:32.32 todor_nikolov erik said to delete it, and i went in lib folder and its not there
15:32.53 brlcad what's the full path?
15:33.13 todor_nikolov path is ../../../lib/libtk.so.8.5 or /lib/libtk.so.8.5
15:33.13 brlcad notice the path is relative to that last make[1] line
15:33.24 brlcad no and no
15:33.33 todor_nikolov oh its inside the project
15:33.39 brlcad the first is not a full path, it's a relative path
15:33.58 brlcad the latter is a full path, but is not the right one (you made that up)
15:34.36 todor_nikolov I found the file
15:34.45 todor_nikolov its in brlcad-build/lib
15:34.50 ankesh11 Fair enough, will try to compare their pros and cons.

16:27.36 Notify 03BRL-CAD:starseeker * 60400 brlcad/branches/openscenegraph/src/libfb/if_osg.cpp: It looks like the issue is rather more fundamental. Essentially, when we invoke the viewer, we're activating the 'this is a scene' aspect of openscenegraph and that doesn't appear to interact well with the low-level drawing calls in the framebuffer. Several options here - figure out what's going on with Tk's events, see if something a
16:27.39 Notify bit more modern like glfw makes a better container, or map adrt's 'framebuffer is a texture on triangles' approach to the libfb framebuffer drawing. All have drawbacks, but it looks like digging deeper into Tk is what will have to happen, at least in the short run.
