13:09.51cad_zulip@**Thusal Ranawaka**: How do you convert the geometry file to a obj file
13:09.54cad_zulip@**Sumagna Das**: anyways, how to do it is written in the task page
13:12.27cad_zulip@**Sumagna Das**: go to terminal or command prompt(in case of windows), type ```g-obj -o (the name you want to give).obj (your .g filename).g sph(if you ran make sph sph)
13:13.32cad_zulip@**Thusal Ranawaka**: "terminal" means?

15:33.36cad_zulip@**Thusal Ranawaka**: Sumagna can you send a screenshot or the URL of your dashboard
15:39.39cad_zulip@**Thusal Ranawaka**: Bye guys
16:24.21cad_zulip@**scorp08**: @**Sean**  Is it a bad idea to leave semaphores in shootrays_parallel and directly feed rt_shootray to bu_parallel ?
17:42.49cad_zulip@**Sumagna Das**: @**Sean**  how to build and compile rtexample.c?
17:43.43cad_zulip@**Sumagna Das**: in the same way, i will also build and compile the c++ program for appleseed #2
18:39.58cad_zulip@**Daniel Rossberg**: You need to set-up your build environment such that it finds BRL-CAD's header files and libraries. You can do this by cloning a project which is doing this, for example from the brlcad or rt^3 repository.
18:39.58cad_zulipOr, you do it by yourself and set the paths and libraries in your CMakeLists.txt, for exmple.
18:54.52cad_zulip@**Sumagna Das**: ok but i csnt do it still
18:56.29cad_zulip@**Daniel Rossberg**: Then, what are you doing?
18:59.01cad_zulip@**Daniel Rossberg**: Remember, I can't see, hear, smell, etc., what you are doing. All I have is this chat. I've no idea what you've tried, typed, etc..
19:00.06cad_zulip@**Sumagna Das**: i changed the cmakelists.txt inside src/rt folder of brlcad (not rt^3)
19:00.37cad_zulip@**Sumagna Das**: and it gave me errors so i did a clean download again
19:00.49cad_zulip@**Daniel Rossberg**: How? (post a patch file with your changes)
19:01.02cad_zulip@**Sumagna Das**: i am gonna try it again
19:01.13cad_zulip@**Sumagna Das**: i deleted it(sorry)
19:05.37cad_zulip@**Daniel Rossberg**: Be as precise as possible. I could write "you did it wrong, if you would do it correctly it would work". This would be totally correct, but also absolutely not helpful.
19:05.37cad_zulipTherefore, provide as much information as possible such that I can point you into the right direction.
19:07.15cad_zulip@**Sumagna Das**: ok
19:07.36cad_zulip@**Sumagna Das**: my internet is not working that well
19:09.17cad_zulip@**Sumagna Das**: so the download is very slow
19:12.19cad_zulip@**Daniel Rossberg**: (Now idea why you have to download the sources again.)
19:13.03cad_zulip@**Sumagna Das**: I deleted the whole thing
19:13.10cad_zulip@**Sumagna Das**: 😐
19:14.11cad_zulip@**Daniel Rossberg**: All of it? You are working with subversion. There you can revert your changes and restore the original sources.
19:24.55cad_zulip@**Sumagna Das**: I forgot in the hustle and bustle around me
19:25.50cad_zulip@**Sumagna Das**: The whole country is going up in fire due to something( i don't know much about it)
19:38.56cad_zulip@**Sumagna Das**: daniel i got this error while make-ing brlcad

19:40.08cad_zulip@**Sumagna Das**: this is is the error
19:40.30cad_zulip@**Sumagna Das**: i did nothing
19:40.50cad_zulip@**Sumagna Das**: it was a clean download
