| Summary | 0001715: Mefisto Mesh Fails since translated by f2c | ||||
| Description | Forum reference - http://forum.freecadweb.org/viewtopic.php?f=3&t=7499#p60921 Mefisto mesh fails to produce a part froma solid in the Mesh Design Workbench. | ||||
| Steps To Reproduce | Make simple shape in Part Workbench, (Cube will do). Go to Mesh Design WB. Select the Cube, (or whatever shape you made), and activate Meshes > Create mesh from shape... Select Mefisto and click OK. | ||||

I can not reproduce the problem using the 64-bit VS11 windows build. Did anyone try to build this using mingw or clang? |

are they using 64bit (integer == long int) operations on arrays of 32-bit values (z == int)? something seems to be horribly wrong. |
|
|
src/3rdParty/salomesmesh/inc/Rn.h:71 //le type Z des nombres entiers relatifs //========= #ifndef PCLINUX64 typedef long int Z; #else typedef int Z; #endif |
|
|
Always defining typedef unsigned long int N; typedef long int Z; in src/3rdParty/salomesmesh/inc/Rn.h solved the problem with gcc on a 64-bit linux. Jürgen, would you mind to check if this works on windows as well and eventually integrate the fix. |

https://github.com/peterl94/FreeCAD_sf_master/commit/ad979421eceb612594a6ca1ad24f292081efe12d or https://github.com/FreeCAD/FreeCAD_sf_master/commit/051dc6d8a6b72a0adc921abbaa6bbb3357370324 sets PCLINUX64. Maybe we should rather not set this macro then modifyling Rn.h? |
|
|
FYI, commenting out the line "ADD_DEFINITIONS(-DPCLINUX64)" doesn't change anything when using MSVC on Windows. |

Testing on Ubuntu 12.04 64-bit without the change: import readline import Part c=Part.makeBox(10,10,10) import MeshPart m=MeshPart.meshFromShape(Shape=c,MaxLength=1) Gives: sh: 1: SMDS_MemoryLimit: not found MEFISTO_2D failed on subshape 0000003 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected.

Address 0" MEFISTO_2D failed on subshape 0000033 with error COMPERR_OCC_EXCEPTION "OSD_SIGSEGV: SIGSEGV 'segmentation violation' detected.
