The problem might be that tbb.dll and tbbmalloc.dll is already installed under c:\windows\system32\. This directory is reserved for system libraries and all other dlls have nothing lost there. The problem is that the OpenCascade dlls try to load these dlls there instead of the local copy. Since tbb is a C++ library and apparently the version in system32 isn't binary compatible none of the OCC dlls load. Solution: Remove or at least rename tbb.dll and tbbmalloc.dll inside c:\windows\system32\ |

That solved the issue. Thank's a lot! Some other folks I work with also share(d) my DLL-Hell-Problem. One could prevent such things with using fully qualified paths to load the needed DLL's. (Also interesting: https://support.microsoft.com/kb/2389418/en-us and https://en.wikipedia.org/wiki/DLL_Hell) |

Apparently does National Instruments Software cause this Problem. To be precise, the IMAQ Image Processing Framework. It seems as if the NI-Framework needs to have these DLL's in the system32 Directory. An option would be to copy the DLL's NI copied to the system32 Directory to the NI-Directory, but then one would have a non-standard NI-Directory-Tree which could lead to further Problems. A workaround for me was to copy the tbb*.dll's from the FreeCAD\bin to the FreeCAD\lib directory. Which solved the Problem, but that's just a workaround. Another option for you would be, to load the Python modules with FreeCAD\bin as search path for DLL-Libraries (if that is possible). (At least do i think that a Python-Module loads the tbb.dll and tbbmalloc.dll from system32.) |

Thanks for the link to the secure loading of DLLs. Very interesting reading. However, I'm not sure what problems it can cause to implement the secure loading because ATM it's possible that users can also use 3rd party Python extension modules like numpy or the like. Now when setting fully qualified paths this won't be possible any more, for sure. > It seems as if the NI-Framework needs to have these DLL's in the system32 Directory.... That's totally insane design IMO. The system directory is reserved for system DLLs and it's taboo for any kind of application DLLs. > At least do i think that a Python-Module loads the tbb.dll and tbbmalloc.dll from system32. It's not a Python module it's one of the Opencascade libraries those starting with "TK". |

Note to myself: In FreeCADInit.py commenting out this block makes the load of PartDesignGui.pyd failing because Part.pyd can't be found. #try: # os.environ["PATH"] = PathExtension + os.environ["PATH"] #except KeyError: # os.environ["PATH"] = PathExtension #path = os.environ["PATH"].split(os.pathsep) #Log("System path after init:\n") #for i in path: # Log(" " + i + "\n") However, when changing the CMake macro SET_BIN_DIR to make all .pyd files to go to ${CMAKE_BINARY_DIR}/lib everything works fine again. |

Note to myself: When putting a faked tbb.dll into system32 then FreeCAD fails to load all OCC-dependent modules. When adding these three lines std::string binPath = TempHomePath; binPath += "bin"; BOOL ok = SetDllDirectory(binPath.c_str()); into Application::FindHomePath and making sure tbb.dll is in the bin directory everything works OK. With SetDllDirectory the DLL search order changes that with the specified path comes BEFORE system32 and system. Also, the CWD is dropped which we don't need anyway. The reason why moving tbb.dll to the lib directory fixes this problem is because the dynamically loaded Python module lies there and apparently this counts as the "application" and not the FreeCAD executable which is inside bin. To sum up: + Add the three liner to fix this issue + Remove the block to extend PATH and create all .pyd's under lib is optional. |
