| 04:34.59 | CIA-48 | BRL-CAD: 03abhi2011 * r47282 10/brlcad/trunk/src/libged/simulate/ (simcollisionalgo.cpp simrt.c): Some corrections to normals and contact pair generation |
| 05:25.52 | abhi2011 | hmm, I need to call the rt related C functions from the c++ code of Bullet's physics pipeline |
| 05:26.22 | abhi2011 | however when I try to call them from within the C++ code, I see to run into undefined reference errors |
| 05:26.40 | abhi2011 | even though I have declared the functions by including the header |
| 05:27.20 | abhi2011 | is it possible to directly call C functions from within C++ |
| 05:29.49 | abhi2011 | hmm there seems to be some compiler mangling of C functions going on, need to smooth the linkage |
| 05:31.02 | abhi2011 | this is turning out to be really loopy....from C code of libged >>>> C++ Code of Bullet >>> C code of RT to get the contact pairs >>>> C++ code of bullet for dynamics >>>> back to C code of libged to finish off |
| 05:38.38 | abhi2011 | ok some useful info here : http://developers.sun.com/solaris/articles/external_linkage.html |
| 05:49.03 | abhi2011 | hmm got around the linkage issue, seems raytracing code has to be inserted right into the bullet nearphase callback to ensure contact pairs are generated at the right place |

| 15:18.00 | CIA-48 | BRL-CAD: 03abhi2011 * r47285 10/brlcad/trunk/src/libged/simulate/ (7 files): Moving towards tighter integration of raytracing with the Bullet pipeline to ensure the contact pairs are injected at the right point during the simulation, added some extern C linkage code to allow this integration |
| 15:29.33 | abhi2011 | cant seem to find a way to get rid of this warning : http://bin.cakephp.org/view/975048800 |
| 17:16.07 | tofu | abhi2011: that's not your problem .. it's a valid warning when compiling that C struct within the context of a C++ file |
| 17:17.18 | abhi2011 | tofu: ok |
| 18:34.05 | tofu | basically, there's a C function (ged_view()) and a struct named ged_view .. |
| 18:34.57 | tofu | struct is == class when compiling in C++, so when it creates the default constructor (ged_view()) it ends up shadowing the existing function |
| 19:26.51 | CIA-48 | BRL-CAD: 03brlcad * r47286 10/brlcad/trunk/ (Makefile.am configure.ac): |

| 19:26.51 | CIA-48 | BRL-CAD: 99 chars or less. ustar increases the limit to 256 chars (tar-pax would |
