| 06:38.17 | nmz787 | can anyone here help with this python-brlcad segmentation fault? here's what gdb shows after apt-get installing python-dbg and running any of the example scripts: http://paste.pound-python.org/show/Uc2G7gr04G9Ytke4WveQ/ |

| 06:40.04 | nmz787 | hi |
| 06:40.15 | nmz787 | know anything about python-brlcad? |
| 06:40.39 | nmz787 | i am getting output that loads in mged, but running the example segfaults |
| 06:40.47 | nmz787 | (in python I guess) |
| 06:40.53 | nmz787 | I am guessing something with SWIG |
| 06:40.59 | nmz787 | but idk |

| 07:06.40 | nmz787 | hmm, i haven't used bt |
| 07:11.30 | nmz787 | ok here it is yukonbob http://paste.pound-python.org/show/gmUKVKnhmDlOWzkWUY5E/ |
| 07:13.38 | nmz787 | got it using this https://blog.cryptomilk.org/2010/12/23/gdb-backtrace-to-file/ |
| 07:14.10 | yukonbob | nmz787: what version of brlcad ? |
| 07:15.08 | yukonbob | oh -- I see 7.24 |
| 07:16.43 | yukonbob | you build from src or use a prebuilt binary ? |
| 07:17.33 | nmz787 | I have the .deb in /usr/brlcad and the built-from-src in /usr/brlcad/dev-7.24.0 |
| 07:17.54 | nmz787 | this run seems to be from the dev version |
| 07:18.12 | nmz787 | but I thought I rebuilt... i might not have removed them from the python lib folder |
| 07:19.01 | yukonbob | it looks like it's failing on freeing a semaphore (if the source is unadulterated). |
| 07:19.23 | nmz787 | setup.py doesn't seem to have a remove arg |
| 07:19.48 | nmz787 | nor uninstall |
| 07:20.33 | nmz787 | one sec |
| 07:21.08 | yukonbob | given the second-last stack is libbu, I think python isn't your biggest concern |
| 07:22.50 | nmz787 | something in here old? https://github.com/kanzure/python-brlcad/blob/master/python-brlcad.cfg |
| 07:24.30 | nmz787 | ya switching to the .deb version seems to give same trace |
| 07:24.55 | nmz787 | http://paste.pound-python.org/show/0iCoJmijYdFejERAwavH/ |
| 07:26.24 | yukonbob | and what steps are you using to generate the fault ? |
| 07:32.47 | nmz787 | clone kanzures github repo, export BRLCAD_PATH=/usr/brlcad && sudo python setup.py install && cd examples && python <any example here https://github.com/kanzure/python-brlcad/tree/master/examples/ > output_will_work.g |
| 07:33.10 | nmz787 | well actually the wdb_primitives doesn't need an output file name |
| 07:33.27 | nmz787 | but yeah, any of them |
| 07:39.41 | yukonbob | so -- does the basic install work ? You're dealing w/ at least two differnt repos/code-bases by the sounds of things ? |
| 07:40.01 | yukonbob | what does the github repo have to do w/ anything... ? |
| 07:41.38 | nmz787 | you mean the install using pip? |
| 07:41.59 | nmz787 | mged in either the .deb install or compiled works and i can do some simple stuff |
| 07:42.46 | nmz787 | and also the python-brlcad (which I got from the github repo) /does/ produce working .g files... I just want to fix the segfault for good measure |
| 07:43.18 | nmz787 | (working as in I can open them using mged and browse the geometry to show the shapes I defined in python) |
| 07:46.39 | yukonbob | well -- *I* am going to sleep for the evening -- but you should try to narrow down the case for faulting -- supplying a long line of pretty big commands doesn't really say much -- |
| 07:46.52 | yukonbob | *what* python called command is causing the fault -- narrow it down. |
| 07:52.56 | nmz787 | oh |
| 07:53.01 | nmz787 | ok |
