| 15:28.56 | brlcad | before turning on all the various protections and worrying about what is linking with what where, I'd like to verify that the default build even works |

| 15:55.11 | starseek1r | Hmm, ducks... pyramid... tea... |
| 15:55.44 | brlcad | historically, the proc-db's are for testing geometry creation, testing new primitives or wdb routines |
| 15:56.37 | starseek1r | So is what ``Erik and I are contemplating something different? |
| 15:56.44 | brlcad | i'm not convinced they make much sense as a library.. they're not really consistent with each other |
| 15:57.00 | brlcad | other than the basic idea that they "make things" |
| 15:57.06 | starseek1r | <evil grin> yet! </evil grin> |
| 15:57.17 | brlcad | they would make nice plugins individually though |
| 15:57.44 | brlcad | i did plan to rewire then like the other 400 tools as modules |
| 15:58.09 | starseek1r | would like to be able to say "I need 5/16in bolts in this wheel" and call the bolt generation routine... |
| 15:58.40 | brlcad | that's all high-level modeling -- you could do that with them as individual plugins or in a library |
| 15:58.47 | starseek1r | after writing the bolt generation routine, apparently... <cough> |
| 15:58.55 | brlcad | there is an mk_bolt already |
| 15:59.02 | starseek1r | Ah, good :-) |
| 16:00.01 | starseek1r | Heh - libnutsandbolts would be awesome :-P |
| 16:00.08 | brlcad | i see them getting tied together at a much higher level where api consistency won't matter, nor will the backend implementation |
| 16:02.21 | starseek1r | isn't quite following - let's say, for example, I want to write a utility at some level that uses routines for nuts, bolts and curved panels to make a hull plate. The hull plate routine would depend on the nut and bolt functionality - how would it invoke them? |
| 16:02.38 | starseek1r | (sorry for being dense...) |
| 16:03.21 | brlcad | it's the "at some level" part |
| 16:03.36 | brlcad | I see that as being a pretty high level as it's almost arbitrary at the low-level |
| 16:04.05 | starseek1r | In other words, a level that doesn't exist yet? |
| 16:04.41 | brlcad | even the existing proc-db's and mk's have little to nothing to do with each other, it would take a lot of effort to make them even *able* to work with each other, and for hardly any large benefit |
| 16:04.51 | brlcad | right, it doesn't exist |
| 16:04.55 | starseek1r | ah |
| 16:04.58 | starseek1r | gotcha |
| 16:04.59 | brlcad | and making it exist is paramount to rewriting most of them |
| 16:05.36 | brlcad | so screw it and integrate them at a higher (probably scripting/plugin) level |
| 16:06.00 | brlcad | where you just need descriptor sheets for what parameters you want to allow, what the various knobs/buttons are, etc |
| 16:06.46 | starseek1r | Ah :-). And in the meantime, in the isolated and unlikely cases where it would be useful now, just throw out a .h file for the function or two needed? |
| 16:07.00 | starseek1r | sees some .h files in there already |
| 16:07.01 | brlcad | it makes a heck of a lot more sense for the images or geometry converters to be integrated into a library than it does the procedural geometry generators |
| 16:08.04 | brlcad | for most of them, "main" is the interface -- you could wrap them up so they all call some given function, but that's trivial |

| 16:41.47 | brlcad | well with just --enable-all, it would have no optimization, so it's not a problem yet |
| 16:42.00 | brlcad | if you'd added --enable-optimized or -O2 or -O3, it should have failed |
| 16:42.19 | kwizart | well i don't think i will build with optimization... what does add optim ? |
| 16:42.30 | kwizart | (other than cflags) |
| 16:42.35 | brlcad | your CFLAGS turns on optimization |
| 16:43.38 | brlcad | our optimization just adds -O3 right now |
| 16:45.25 | kwizart | we don't distribute package with -O3 for now... maybe a can add a rpm macros to ease the rebuilt of some component (not all probably) that would need -O3 to be more efficient |
| 16:46.20 | kwizart | i will need to figure out how can i split components for the brlcad rpm package.. |
| 16:46.33 | brlcad | kwizart: I'm not saying you want/need O3 :) |
| 16:46.34 | kwizart | with some sub-packages |
| 16:46.39 | brlcad | the difference from O2 is minor |
| 16:46.53 | brlcad | but either O2 or O3 without -fno-strict-aliasing is a problem |
| 16:47.03 | brlcad | any O level |
| 16:47.16 | brlcad | try your CFLAGS but also add -fno-strict-aliasing |
| 16:47.26 | kwizart | yep it build |
| 16:47.29 | brlcad | see if that results in RIGHT |
| 16:48.28 | brlcad | it could still be some odd interaction with _FORTIFY_SOURCE ssp mods, but strict aliasing is a known problem |
| 16:48.39 | kwizart | at least i will need OpenNurbs to be built externally. at least |
| 16:50.02 | brlcad | that probably won't work, we've made opennurbs modifications directly |
| 16:50.31 | brlcad | there are plans to move the changes out of opennurbs, but as it presently stands written, you can think of opennurbs as just another internal library |
| 16:50.40 | kwizart | we can disable the some cflags under certains circumstances - but we discuss that maybe that also x86_64 problem... don't know much |
| 16:50.59 | brlcad | hm? |
| 16:51.02 | kwizart | about OpenNurbs i will probably take a snapshoot from the brlcad release |
| 16:51.18 | brlcad | there shouldn't be any need to disable any of those cflags |
| 16:51.30 | brlcad | and we do work on x86_64, it's regularly tested |
| 16:51.35 | kwizart | i don't know any FOSS project other than brlcad using it for now |
| 16:51.55 | brlcad | yep, and I doubt any would .. it's pretty niche to the CAD industry |
| 16:52.44 | brlcad | maybe blender or avocado at some point, but not likely |
| 17:01.46 | CIA-20 | BRL-CAD: 03brlcad * r30815 10/brlcad/trunk/configure.ac: this has happened several times now. make a note that -fno-strict-aliasing is REQUIRED if any level of optimization is enabled (and we're using GCC as we do use and rely on aliasing and type-punning. |

| 17:03.07 | ``Erik | when I was first doing the move from cake to automake, that bit me bigtime... |
| 17:03.35 | ``Erik | and I presented my argument and the point that many others have done that switch, but lbutler resisted :/ |
| 17:03.42 | brlcad | I've come to appreciate the bu_list style use, but it's the pointer tables that break with -fno-strict-aliasing iirc |
| 17:04.26 | brlcad | related to bu_list's of course |
| 17:06.26 | ``Erik | I appreciated the approach and had been sufficiently beaten down to step back and consider |
| 17:06.40 | ``Erik | there're better ways to accomplish the goal given the limitations |
| 17:06.42 | ``Erik | :/ |
| 17:06.50 | ``Erik | I could not convince lee of that |
| 17:07.46 | brlcad | such as? |
| 17:08.39 | brlcad | bu_lists are pretty damn prevalent ... |
| 17:08.41 | ``Erik | hrm? whichwhat? |
| 17:09.01 | brlcad | "better" ways to accomplish the goal |
| 17:09.03 | ``Erik | old bsd linked list used to be exactly that, new bsd linked list doesn't do that |
| 17:09.16 | ``Erik | instead using container style |
| 17:10.05 | ``Erik | when I was doing the conversion, fbsd had JUST gone through a fairly painful migration from old cast style to new LISt style |
| 17:10.40 | brlcad | it would be painful for us too, quite .. |
| 17:10.48 | brlcad | probably at least 10k instances of use |
| 17:11.08 | brlcad | non-regexable |
| 17:12.07 | ``Erik | tends to be the case |
| 17:12.17 | ``Erik | I tried to fix it back when it was easily fixable |
| 17:12.31 | brlcad | maybe as low as 877 though, if the macro wrappers are consistently used (which they're not) |
| 17:12.35 | ``Erik | lee took a moral stance on it.. I was new to the project and job, so I folded too soon :/ |
| 17:12.55 | ``Erik | "if I knew then what I know now" |
| 17:13.02 | brlcad | meh, it's rather bikeshed |
| 17:13.22 | brlcad | it's just an optimization based on a false assumption that C allows for |
| 17:13.31 | ``Erik | i'd disagree |
| 17:14.02 | brlcad | so you can feel strongly for or against it, but it's not like it's inherintly right or wrong imo |
| 17:14.20 | ``Erik | it's an optimization based on assumption that every developer is fully aware of the ugly implifications of the reprecussions that the dirty cheats C allows for |
| 17:14.47 | ``Erik | I mean, a fistful of guru C coders? SURE, bits is bits, we know how it all hammers out |
| 17:15.16 | ``Erik | the minute you throw in someone who isn't qualified to chum among the "greybeard" gurus... uh, we get little hard to track issues |
| 17:15.29 | brlcad | eh, that's not disagreeing with what I said -- except maybe that it's a "false assumption" |
| 17:15.42 | brlcad | i'm saying it's false *because* C allows for it |
| 17:15.56 | brlcad | not saying that it should or should not be used |
| 17:16.14 | brlcad | THAT is what makes it bikeshed -- if it's to be resolved otherwise, C should be modified |
| 17:16.20 | ``Erik | it's not illegal, it's dangerous :D I think we're in violent agreement |
| 17:18.22 | ``Erik | I'm a bsd junkie, I watched them expunge themselves of exactly this, I think they did the right thing in more orless the right way... *shrug* with the move from fbsd 5 to fbsd 6 iirc |
| 17:19.25 | kwizart | ok well that was my bad - it seems to work with our cflags and -fno-common -fno-strict-aliasing |
| 17:20.19 | brlcad | it's just so petty, though .. I mean say you do the whole conversion, spend the days/weeks/months refactoring hundreds to thousands of lines of code .. and *don't* actually inject new bugs .. you basically end up where you started |
| 17:20.34 | brlcad | i mean "maybe" with a percent or two optimization gain at *best* |
| 17:20.37 | ``Erik | NEEDS -fno-strict-aliasing, for exactly the thing brlcad and myself are talking about here |
| 17:20.59 | brlcad | kwizart: you shouldn't need (or care) about -fno-common on linux |
| 17:23.43 | kwizart | Elapsed compilation time: 14 hours, 56 minutes, 37 seconds |

| 17:24.03 | kwizart | Elapsed time since configuration: 20 minutes, 22 seconds |
| 17:24.23 | brlcad | it means your clock probably recently crossed midnight |
| 17:25.29 | brlcad | or just that you started building 14 hours ago |
| 17:25.37 | kwizart | 19h25 |
| 17:25.38 | brlcad | when you first ran make |
| 17:26.10 | brlcad | it's based off of the build stamp in include/conf and if you've not ran make clean, that'll just keep getting bigger |
| 17:26.18 | kwizart | start building20min ago , unless it took distcc content... it is recreated each time... |
| 17:26.24 | kwizart | with rpmbuild -ba |
| 17:26.48 | brlcad | reiterates .. it's based off of the build stamp in include/conf and if you've not ran make clean, the compilation time will just increase |
| 17:27.34 | brlcad | *or* maybe you're pulling from a source tarball where there's a date stamp already in there |

| 18:03.46 | starseek1r | In C, how do I generate the name of a function to call and then call it? (e.g., say I have draw1, draw2 and draw3 defined and I want to do a for loop for i = 1 to three call draw$i? |
| 18:05.29 | brlcad | you would usually use macros, have defined call-table mappings, or use dynamic loading |
| 18:05.40 | brlcad | what are you actually trying to do? |
| 18:07.40 | brlcad | unless you have dozens to iterate over, you'd probably should just call draw1(); draw2(); draw3(); |
| 18:10.21 | starseek1r | The idea is there may be an unknown (to tire) number of possible wheel or tread styles defined |
| 18:12.50 | starseek1r | I want to specify on the command line -t 8 and have tire attempt to draw tread pattern 8. I'd like the routine that attempts to draw different patterns to be generic, and not need editing each time a new tread is defined |
| 18:15.15 | brlcad | they're not unknown in code, though -- they have to be in there |
| 18:16.04 | brlcad | with that specific example, you could have an array of function pointers and -t 8 would give you the 8th function pointer |
| 18:16.39 | starseek1r | heh - bob suggested that too :-) Could you recommend a good tutorial/example on using function pointers in C? |
| 18:16.48 | brlcad | google? :) |
