Hi! All I am trying to test if OCC based CGM is working correctly in my computer. It looks OCC and CGM are installed well, but the test program "CGM/itaps/testgeom_occ" is not working. When I try "testgeom_occ", I got an abort signal (SIGABRT). The following is a backtrace function list from debugger. -------------------------------------------------------------------------------------------------- (gdb) bt #0 0x00007f3bf70877e0 in ??

So, I'd like to check at first if "testgeom_occ" and the input file "test/LeverArm.brep" are really working for others. Otherwise, could anybody tell me some advices to solve this problem? Thank you.
