00:20 <@matches> I only saw it because it is also outside an #ifdef and raises an "unused label" warning
00:20 <@matches> How many others are there...
00:24 <@matches> There is also a goto in stb_truetype.h but I'll let that one slide since sulix didn't write it
+10:01 < sulix> Gah: runs fine, no warnings in valgrind, crashed with memory corruption errors outside of valgrind.
+10:02 < sulix> This is clearly karmic retribution for the goto.
+10:25 <@matches> Ah
+10:25 <@matches> Are you compiling with or without the quadtree?
+10:25 <@matches> Because I set the VReal and PReal typedef to ParanoidNumber
+10:26 <@matches> Running in valgrind ParanoidNumber is equivelant to a double since the FE_INEXACT exception isn't raised
+10:26 <@matches> Running outside of valgrind... anything could happen
+11:31 <@matches> One does not simply compile with MinGW and have things actually work
+11:32 <@matches> Wine likes it
+11:32 <@matches> Actual windows seems to have some difficulty with OpenGL functions
+11:32 <@matches> Also thank goodness for gdb compiled for windows
+11:33 <@matches> Because "ipdf.exe has experienced an error, would you like to send Microsoft a report?"
+11:33 <@matches> Is really not helpful
+11:33 <@matches> Command prompt won't even tell you "Segmentation fault"
+11:39 <@matches> Hmm, needs more "-lopengl32" ?
+11:39 <@matches> But why weren't there "undefined reference" errors
+11:39 <@matches> So confuzled
+11:40 <@matches> I bet even if it runs it won't work due to geometry shaders or something
+11:49 <@matches> Oh dear
+11:49 <@matches> This is to do with the several thousand lines of autogenerated stuff in gl_core44.*
+11:50 <@matches> Isn't this what GLEW was supposed to be for
+11:50 <@matches> Except GLEW is ancient so nobody uses it
+11:50 <@matches> Shouldn't someone reinvent a less shitty GLEW then
+11:50 < sulix> Apparently glew works again.
+11:50 <@matches> Ah
+11:51 < sulix> I did get glew working under mingw32 yesterday, as it happens.
+11:51 <@matches> Commit please?
+11:51 <@matches> Oh right for something else :P
+11:51 <@matches> What magical incantations are required
+11:51 < sulix> Yeah. And by working, I mean compiling, not running.
+11:51 <@matches> Baha
+11:52 < sulix> (Though I think it was another bit of the code that segfaulted)
+11:52 <@matches> Why is getting OpenGL working so horrifying
+11:52 <@matches> It's supposed to be a standard
+11:52 < sulix> So the gl_core44.* file was supposed to be basically glew, but hooked into SDL.
+11:52 <@matches> It's not working on Windows though
+11:53 < sulix> Do you have OpenGL drivers on windows?
+11:53 < sulix> They're not installed by default.
+11:53 <@matches> Yeah on my desktop
+11:53 <@matches> Although I did switch to Maaxen
+11:53 < sulix> Hmmm...
+11:53 <@matches> There were other things wrong
+11:53 <@matches> I wasn't liking with -lopengl32
+11:54 <@matches> Although wine didn't seem to care
+11:54 < sulix> In theory, the glcore44 and SDL stuff should load opengl32 at runtime if needed.
+11:54 < sulix> So you shouldn't, in theory, need to link to them.
+11:54 < sulix> But that's very much "in theory".
+11:55 <@matches> I will investigate the driver situation on Maaxen
+11:55 <@matches> Urgh why can't windows just have `apt-cache search`
+11:55 <@matches> And `lspci | grep vga`
+11:55 <@matches> Lets see... "Device Manager"
+11:55 < sulix> Maaxen will almost certainly not have working GL 3+ drivers.
+11:56 <@matches> Oh it's a VM
+11:56 * matches backs away very quickly
+11:56 <@matches> Well I can't keep rebooting every time I try and fix a segfault
+11:56 <@matches> Bloody scope broke my other laptop
+11:57 <@matches> I used to have Windows XP...
+11:57 <@matches> Oh wait I smashed the hard drive open so I could draw it for an assignment
+11:58 < sulix> You should subscribe to the "if it works under wine, it's good enough" philosophy.
+11:58 * sulix has shipped things that way.
+12:00 < sulix> Anyway, the quadtree is still segfaulting when not run under valgrind by (I think) getting the video card to somehow corrupt unrelated system memory or something.
+12:00 <@matches> :S
+12:01 < sulix> It always crashes when trying to glDeleteBuffers() which is really disturbing.
+12:02 <@matches> I've noticed that when there are a lot of objects, and you kill the program, you never get the memory back ever
+12:02 <@matches> And your system stays slow
+12:02 <@matches> Which is a bit of a problem
+12:02 <@matches> Need to reboot every hour or so of testing...
+12:02 < sulix> Okay, I haven't had that happen.
+12:02 <@matches> I guess that's just fglrx amazingness
+12:03 < sulix> Guess so.
+12:03 <@matches> For example, I can run turtles_all_the_way_down.script without anything crashing but then I am left with like 20MB and when I open Iceweasel everything goes to hell
+12:03 < sulix> On the bright side, the fglrx developers are planning to get rid of the fglrx kernel module and just have their closed-source GL driver talk to the open-source kernel driver.
+12:04 <@matches> Is that... good
+12:04 < sulix> We'll see, but I can't imagine it making fglrx _worse_
+12:04 <@matches> The open source driver doesn't work that well either
+12:05 <@matches> I sense another few days trying to get X working again after an `apt-get upgrade` at some point in the future then :(
+12:08 < sulix> Don't worry, they're still in the "have meetings" phase.
+12:37 <@matches> I think the glDebug stuff is giving windows issues
+12:37 <@matches> At least running in actual windows not a VM
+12:37 <@matches> Running in a VM is not conductive to working
+12:37 <@matches> Sanity tells me to give up
+12:38 <@matches> It can do glCreateProgram though!
+12:38 <@matches> glObjectLabel seems broken
+12:39 < Pommers> http://th01.deviantart.net/fs70/PRE/i/2012/076/1/2/oh_my_glob__by_tsubasaangel-d4t0g68.jpg Oh my glOb
+12:39 <@matches> Yes
+12:40 <@matches> It would be nice if the extension manager (if you could call gl_core44 that?) used stubs instead of NULL
+12:41 <@matches> I mean for debugging
+12:41 <@matches> Then you can have it print "This function doesn't actually exist guys"
+12:41 <@matches> gdb is nicer I supose
+12:41 <@matches> In fact if I weren't trying to cross compile on linux and then reboot and test in windows this would be a lot easier
+12:58 <@matches> Ok screw this
+12:58 <@matches> I need to write a thesis
+12:58 <@matches> :(
+12:58 <@matches> But after lunch
+13:51 <@matches> http://thecodelesscode.com/case/57
+14:12 < Pommers> Lunch sounds good
+14:23 <@matches> I'm currently reading codelesscode using the excuse that the turtles tester takes a very long time to sigfpe
+14:23 <@matches> (But it sigfpe's nonetheless)
+14:24 <@matches> Can we disable sigfpe for overflow/underflow casts from double to float
+14:24 <@matches> That would make things easier
+14:24 <@matches> Well
+14:24 <@matches> Assuming that the float casts to FLT_MAX or FLT_MIN if it would underflow/overflow
+16:09 <@matches> sulix: I can no longer load anything into the document
+16:09 <@matches> Congratulations though, this means it always renders accurately...
+16:20 <@matches> Ok...
+16:20 <@matches> We now have
+16:20 <@matches> #ifdef
+16:20 <@matches> ...
+16:21 <@matches> m_count++;
+16:21 <@matches> return m_count;
+16:21 <@matches> #else
+16:21 <@matches> return m_count++;
+16:21 <@matches> #endif
+16:22 <@matches> Because I don't know if the quadtree *needs* to return an invalid array index (it doesn't even use the same array...) but over in monotree land we like our array indices to be valid
+16:24 <@matches> Now what was I doing
+16:24 <@matches> Ah, seeing if OpenGL really could do Wu lines
+16:25 <@matches> So when I say it is in my report I am not lying
+16:25 <@matches> Report...
+16:25 <@matches> The thing I'm writing
+16:25 <@matches> Write
+16:25 < Pommers> How long is the report going to be matches?
+16:25 < Pommers> And when are you going to finish it?
+16:25 <@matches> It has to be 6000 words
+16:26 <@matches> My LitReview is ~8000 ...
+16:26 <@matches> Although that might be including the SVG and postscript examples
+16:26 <@matches> I think I should take those out?
+16:26 <@matches> You'd think having a huge pre-written document would make it easier but no
+16:27 <@matches> Enabling LINE_SMOOTH leads to, of all things, SIGFPE
+18:25 <@matches> I am making a whole lot of no progress here
+18:25 <@matches> Draft due on Friday...
+18:26 <@matches> I need to produce a Design Process
+18:26 <@matches> The software wasn't so much designed as congealed
+18:27 <@matches> I forgot this is an Engineering Project not CS and therefore needs to be done in such a way that future Engineers can improve upon the work...
+18:27 * matches sobs some more
+18:27 <@matches> Rectangles and Circles don't even work anymore
+18:28 <@matches> I sacrificed them for the glory of the Bezier To Path transformations
+18:29 <@matches> Also, instead of a transformation per path, it would make more sense to use one per SVG
+18:30 <@matches> It's basically the localised coordinate approach but not as fancy as a quadtree
+18:30 <@matches> If you were building up a document one bezier at a time by drawing them, you'd have to do something fancy to make your paths
+18:31 <@matches> (Un)Fortunately we don't have an editor anyway
+18:47 <@matches> Hmm, that really needs reverse parenthesis to indicate that the word is "Unfortunately" but the "Un" is removed
+18:47 <@matches> )Un(Fortunately
+18:47 <@matches> I have invented a new gramatical construct-thing
+18:47 * matches adds it to the list of results
