| 02:58.22 | brlcad | argv[0] |
| 03:00.39 | tegtmeye | lol, besides that. I thought that there was a system call that would give you that |

| 03:02.13 | brlcad | depends how cross-platform you want to be |
| 03:03.20 | brlcad | iff your system supports getprogname(), you can use that -- you need to setprogname() unless you presume bsd-style behavior (where it's run automatically for you before main()) |
| 03:03.25 | tegtmeye | very. need it for a library that gcc calls |
| 03:04.06 | brlcad | those two are basically equiv to writing your own little function that stashes the argv[0] value in a static/global |
| 03:05.45 | tegtmeye | problem is, I don't have access to the application source |
| 03:06.24 | tegtmeye | so I can't stash argv[0], maybe I was thinking that getprogname was posix, been a long time... |
| 03:07.29 | brlcad | afaik, there's not a posix way to get at it |
| 03:07.58 | brlcad | you don't have any access to the original argv? |
| 03:11.44 | tegtmeye | no. I'm building a library that does some dynamic analysis. So the uses sets up some compiler switches in gcc and links this in. |
| 03:12.45 | tegtmeye | So, in general, I don;t have access to the source and I don't want to have them call mylib::init(argc,argv) or whatever |
| 03:14.49 | brlcad | you can make your own routine that tries the various platform-specific ways |
| 03:15.06 | brlcad | there's a win32 function, i'd have to look it up |
| 03:15.33 | ``Erik | (define-syntax mycond (syntax-rules (else) ((_ (else a)) a) ((_ (p a)) (if p a)) ((_ (p a) r ...) (if p a (mycond r ...))))) |
| 03:15.35 | ``Erik | sweet |
| 03:17.01 | ``Erik | and, of course, the corellary... (define-syntax myif (syntax-rules () ((_ p t e) (cond (p t) (else e))))) |
| 03:17.09 | tegtmeye | I thought there was a way to find out from the pid. The info has to be stored somewhere if 'ps' is getting it. |
| 03:17.11 | ``Erik | *flex* |
| 03:17.16 | ``Erik | getpid() |
| 03:17.34 | brlcad | getprogname'll work on all the bsd, getexecname() on solaris iirc, can query /proc on linux |
| 03:17.48 | ``Erik | ooh, heh |
| 03:18.13 | brlcad | i believe there is a global that glibc provides as well |
| 03:18.41 | ``Erik | um, there was a path expansion function that you could feed argv[0] to I think, I don't recall the name |
| 03:19.31 | brlcad | program_invocation_short_name is one of the globals potentially available iirc |
| 03:19.48 | tegtmeye | hmmm... |
| 03:23.32 | brlcad | /proc/self/cmdline |
| 03:25.36 | tegtmeye | no /proc on mac (assuming bsd as well) |
| 03:30.04 | brlcad | mac has getprogname |
| 03:30.10 | brlcad | there's no single-shot answer |
| 03:30.18 | brlcad | i'm saying you can use the combination of them all |

| 06:05.32 | birdmun | i asked hours ago about where mged is ... problem is i dont see it in the usr/brlcad/bin dir |
| 06:06.44 | pra5ad_ | did u make install? |
| 06:09.11 | birdmun | yes |
| 06:09.34 | brlcad | what's in your /usr/brlcad/bin dir? |
| 06:09.41 | brlcad | lot of binaries? |
| 06:09.51 | pra5ad_ | yes |
| 06:10.01 | birdmun | 189 exe files |
| 06:10.07 | birdmun | 188 |
| 06:10.08 | brlcad | eek |
| 06:10.28 | brlcad | should be over 400 |
| 06:10.31 | birdmun | i guess that means make install didnt work |
| 06:10.33 | birdmun | ? |
| 06:10.34 | brlcad | how'd you build? |
| 06:10.41 | brlcad | sounds like make install failed part way |
| 06:10.50 | brlcad | or make failed, so make install failed |
| 06:10.58 | birdmun | make finished |
| 06:10.59 | pra5ad_ | is there a flag for ls that produces a filecount? |
| 06:11.06 | pra5ad_ | or do i have to gawk |
| 06:11.11 | brlcad | ls -la1 | wc |
| 06:11.28 | pra5ad_ | 351 |
| 06:11.41 | brlcad | eh, that's not right either :P |
| 06:11.44 | pra5ad_ | 913 |
| 06:12.02 | brlcad | nor is that |
| 06:12.03 | pra5ad_ | woops |
| 06:12.15 | pra5ad_ | 434 |
| 06:12.24 | brlcad | that's more like it |
| 06:12.40 | brlcad | 438 is current iirc |
| 06:12.53 | birdmun | after the make worked properly i should be able to go back to the dir and just run make install yes? |
| 06:12.56 | pra5ad_ | 436 |
| 06:13.12 | brlcad | sure, presuming make worked |
| 06:13.19 | brlcad | you should be able to go back and run make again too |
| 06:13.23 | brlcad | and it should just iterate |
| 06:14.25 | birdmun | when make finished it listed how long it took to make ... i ran make benchmark ... i dont recall any errors there |
| 06:14.44 | brlcad | yes, but did make list any errors |
| 06:15.25 | brlcad | and did mged compile |
| 06:15.31 | brlcad | ls -la src/mged/mged |
| 06:16.11 | brlcad | ls -la src/mged/.libs/*mged* |
| 06:16.31 | birdmun | src should be in the usr/brlcad/ dir? |
| 06:16.39 | brlcad | no |

| 06:19.07 | brlcad | so maybe make install is failing for some reason |
| 06:19.08 | birdmun | i have nothing listed in the .libs dir tho |

| 22:30.02 | brlcad | oh? |
| 22:30.24 | Loes | i'm new to linux |
| 22:30.41 | Loes | i tried it on my mac |
| 22:30.51 | Loes | there it worked |

| 22:41.07 | Loes | compiling from source isn't working |

| 23:31.57 | Loes | I see you can export it to other formats |
| 23:32.03 | brlcad | tsk tsk |
| 23:32.28 | brlcad | yes, there a 3d export and 2d export formats with various implications |
| 23:33.15 | Loes | so I could export it to f.e. autocad, which has that feature |
| 23:36.18 | brlcad | that you theoretically could |
| 23:37.34 | Loes | all I'm looking for, is a program that can replace solid edge/autocad etc |
| 23:37.51 | Loes | do you think brlcad can doo that? |
| 23:38.35 | Loes | or is it designed for other purposes? |
| 23:38.55 | brlcad | fyi, there are certain versions of autocad that don't parse their own format according to their own specification, our next release will work around it and output something more flexible to their parsers |
| 23:39.08 | brlcad | it can, depends entirely on the purpose |
| 23:39.27 | Loes | i'm a student mechanical engineering |
| 23:39.33 | brlcad | the primary history/focus of the package of the years was solid modeling for the purpose of performing analysis/simulations |
| 23:39.51 | Loes | and i'm using mac, so it's very hard to find 3d software for that |
| 23:40.10 | brlcad | we've got quite a mech-e following |
| 23:40.29 | brlcad | brl-cad's not a good drafter, ala autocad |
| 23:40.31 | Loes | i must say, your program looks good |
| 23:40.47 | Loes | (not easy though :) ) |
| 23:40.52 | brlcad | hence limited 2d drafting support, parametrics, dimensions, etc |
| 23:41.10 | brlcad | otherwise, it is a full-fledged solid modeling system, mature and in production use |
| 23:41.33 | brlcad | and it's open source and free as in beer and speech |
| 23:41.50 | Loes | indeed |
| 23:41.58 | Loes | that's nice (for a student) |
| 23:41.59 | brlcad | so anyone can help improve it, become one of the devs |
| 23:42.38 | brlcad | it's ideal for certain students, imo -- i would have loved having it as a base for my computer graphics and vision work in college |
| 23:42.56 | brlcad | even single processing |
