| 14:05.37 | ksuzee | the result is normal - out.pix is generating |

| 14:07.03 | ksuzee | after refactoring - the same result |
| 14:08.18 | ksuzee | Why is this exception thrown? |
| 14:09.32 | brlcad | ksuzee: it sounds like you're using some tool wrong |
| 14:09.47 | ksuzee | hmm |

| 14:18.34 | brlcad | ksuzee: you've done more than that |
| 14:18.44 | brlcad | otherwise nothing you just said involved png |
| 14:18.58 | brlcad | so again, you're doing something wrong :) |
| 14:19.30 | brlcad | try reading the manual pages for each of the commands you're using to make sure you're using them right |
| 14:19.40 | brlcad | brlman command_name |
| 14:21.15 | ksuzee | and where ecxeclty can I use brlman? Not in every directiry as I see) |
| 14:21.24 | brlcad | brlman is a command |
| 14:21.31 | ksuzee | yes, i see |
| 14:21.38 | ksuzee | aaa |
| 14:21.43 | brlcad | it doesn't matter where you run it from |
| 14:21.56 | brlcad | it's like running ls |
| 14:22.07 | brlcad | or 'man' (which is exactly what it's doing actually |
| 14:22.14 | brlcad | man blah |
| 14:22.24 | ksuzee | I know this |
| 14:22.34 | ksuzee | but command not found Oo |
| 14:22.46 | brlcad | okay, but consider your question |
| 14:23.00 | brlcad | especially if man==brlman |
| 14:23.24 | brlcad | "and where exactly can I use man? (Not in every directory apparently)" |
| 14:23.34 | brlcad | paraphrased and corrected, but that's what you said |
| 14:23.38 | brlcad | does that make sense? :) |
| 14:23.46 | brlcad | where can you use the 'man' command? |
| 14:23.49 | brlcad | you can use it anywhere |
| 14:23.52 | ksuzee | every where)) |
| 14:24.01 | ksuzee | *everywhere |
| 14:24.04 | brlcad | so what were you really trying to ask? |
| 14:24.44 | ksuzee | emm) I can run brlman only from /bin |
| 14:24.54 | ksuzee | that's why I asked) |
| 14:25.34 | brlcad | you're lacking some precision in what you're writing, which is making it difficult to help you |
| 14:25.44 | brlcad | you certainly are NOT running brlman from /bin |
| 14:26.15 | brlcad | maybe from your cmake build_dir/bin directory |
| 14:26.38 | brlcad | which means you haven't installed (which is fine, but then you have to give the path to commands not in your system PATH) |
| 14:26.39 | ksuzee | yes |
| 14:27.10 | brlcad | I can't read your mind very well, you need to be specific :) |
| 14:27.17 | brlcad | at least not on thursdays ;) |
| 14:27.24 | ksuzee | hah)) I'm sorry)) |
| 14:27.59 | brlcad | so it sounds like you're not familiar with how unix PATH works? |
| 14:29.32 | ksuzee | PATH Environment you mean? |
| 14:30.56 | ksuzee | Shall I do like this - export PATH=$PATH:/new/path (with brlman)? |
| 14:31.18 | brlcad | so mini unix tutorial |
| 14:31.35 | brlcad | when you run a command, say "man" or "ls" or even "pix-png" or "brlman" |
| 14:31.49 | brlcad | it looks at each directory in the $PATH environment variable |
| 14:32.11 | brlcad | that's when it's just a command name |
| 14:32.26 | brlcad | if it finds the command, it obviously runs it and all is good |
| 14:32.44 | brlcad | if it doesn't find the command, you get a command not found error |
| 14:33.05 | brlcad | the OTHER way you can run a command is by specifying the path to it |
| 14:33.44 | brlcad | running "/usr/bin/ls" for example doesn't read the PATH variable, it looks for ls in the /usr/bin directory and if it finds it, the application is run |
| 14:33.59 | brlcad | same with relative paths like ../../../../usr/bin/ls |
| 14:34.18 | brlcad | or path/to/your/build/bin/pix-png |
| 14:34.49 | brlcad | so when you run "brlman" without a path, it's going to search $PATH |
| 14:35.15 | brlcad | if you run "path/to/build/bin/brlman", it'll run it if it finds the application in that path |
| 14:35.24 | brlcad | SO... |
| 14:35.37 | ksuzee | Now I understand |
| 14:35.45 | ksuzee | I've just done so |
| 14:35.49 | ksuzee | and it works)) |
| 14:35.51 | brlcad | you either need to make sure you have a bin directory in $PATH or run commands by specifying the path/to/them/bin/herre |
| 14:36.21 | ksuzee | thank you a lot! Now brlman is as man |
| 14:36.31 | ksuzee | I knew about PATH |
| 14:36.52 | brlcad | so now the question is did you add your build directory bin directory or did you install and add your install directory to PATH? |
| 14:36.55 | ksuzee | but I didn't have to use it before |
| 14:37.34 | ksuzee | I added build/bin to the path |
| 14:38.17 | brlcad | okay, that's fine but recognize that it's not *usually* what you would do with PATH |
| 14:39.10 | brlcad | if you do another checkout of brl-cad, for example, and simply put it in another directory, it's going to be running binaries from the other build dir and you might not expect that |
| 14:39.15 | Stattrav | if not thursdays do you read people's minds ? |
| 14:39.22 | brlcad | Stattrav: maybe |
| 14:40.04 | brlcad | ksuzee: so it's fine -- just be careful if you move things around or get more checkouts |
| 14:40.07 | Stattrav | brlcad: adding a logger class to the libs so that could be used by everything else |
| 14:40.47 | brlcad | the usual way would be to just run with a relative path like "./bin/brlman" or perform a "make install" and add /usr/brlcad/bin to your PATH |
| 14:41.01 | brlcad | (but then you have to run make install every time you rebuild |
| 14:41.14 | ksuzee | yeah, I see this. Thanks a lot! So I'll read about pix-png) |

| 15:29.24 | Wolfram74 | should the last line be " U brlcad"? |
| 15:29.24 | brlcad | ../configure --enable-all && make |
| 15:29.41 | brlcad | it'll give you a prompt again when it's done |
| 15:29.49 | brlcad | probably |
| 15:29.54 | Wolfram74 | k |
| 15:30.27 | brlcad | the build will probably take 10-15 minutes depending on how fast your mac is |
| 15:31.09 | brlcad | IF you don't see an error at the end after running that "./configure --enable-all && make" line, run: sudo make install |
| 15:31.21 | brlcad | if you see an error, mention it here and we can try the cmake build system instead |
| 15:31.41 | brlcad | in the meantime, I gotta run to lunch, but will be back in about an hour |
| 15:32.10 | Wolfram74 | executing ./autogen.sh, thanks for the help |
| 15:33.57 | brlcad | no problem |
| 15:38.29 | Wolfram74 | so it seems automake failed |
| 15:38.58 | Wolfram74 | perhaps because i didn't have liptoolize? |
| 15:39.34 | Wolfram74 | i duuno, you're at lunch so i'll work on something else till about 1800 GMT and check back |

| 20:45.27 | Al_Da_Best | Does brlcad have a factorial function? |
| 20:49.27 | ``Erik | erm, no? why? |
| 20:51.48 | Al_Da_Best | I want to work out the number of forces acting between x number of objects (gravity acting on each other), planned to use binomial coeff's for that |
| 20:53.02 | ``Erik | soooooo, use something like static double fact(double x) { return x<=1.0?1.0:x*(fact(x-1.0)); } |
| 20:53.25 | CIA-65 | BRL-CAD: 03tbrowder2 * r50797 10/brlcad/trunk/doc/README.Windows: correct typo |
| 20:53.48 | Al_Da_Best | Yeah recursion will sort it, just wondered if there was anything built in already |
| 20:54.12 | ``Erik | nah, nothing built in, too trivial to bother |
| 20:54.23 | Al_Da_Best | Fair enough :D |
| 21:57.48 | tbrowder2 | ref factorial: how many objects are you planning to handle? |
| 22:28.23 | Al_Da_Best | That's an issue I'm having a look at alternatives for. There could be a lot, depending how many the user inputs. Problem of stupidly large numbers. I can just make an array more than big enough to begin with, but I'd rather not if avoidable. |

| 22:58.15 | tbrowder2 | ADBest: we may want to have a bn_factorial function that would handle all N <= ~ 64 (say using lookup for first 20, then something like Sterling's approx., etc.) |
| 23:00.09 | Al_Da_Best | Yeah that could be useful |
| 23:12.23 | ``Erik | or store the edges in a list, tree, hash, or other data structure instead of an array |
| 23:13.05 | Al_Da_Best | Yeah I'm using a linked list with structs now, much more flexible. |
