So i tried to change to c++17, but now i get some other errors.... So you built nglib with C++17, and then FreeCAD with C++17? I have zero netgen skills but will try. Hopefully tomorrow. Thanks for the work @apeltauer :D , it's much appreciated. Netgen was ported to C++17. I tried to compile it wit...

Like i already mentioned, the fem workbench does not start anymore with occ 7.4. I still think it is because of the netgen stuff. I have compiled netgen (current master state, commit hash (538ca486fd07af0ca7ec77c4fdee3d6eb5950dd9)). But now i get some errors in the FC netgen support because netgen n...

I agree. You could also update Python 3.x in a next step. We should maybe also upgrade from VC 2015 to VC 2017 to save maintenance work. I think only supporting 2 VC versions saves a lot of time. For this reason I killed VC 15 on my development PC. Visual Studio 2015/2017/2019 are binary compatible...

Many thanks! While you are at it, could you please upgrade Qt to Qt 5.12.6? (I don't know if there are bugs in the current 5.12.1 but I think having the latest Qt 5 LTS version is a good thing). I dont know if i have to compile pyside2 and all other gui stuff against QT5.12.6. So for now i would sa...

Some while ago somebody using Debian was using OCCT 7.4 and many compiler issues should be fixed in current master. 7e60631239 851e3d984 bf5923c0f360 2a9205119278293 5095703776 Update: Compiling just worked with 3 little modifications: The header file BRepMesh.hxx was removed by OCC. So i include #...

This would be nice. As far as I read in OCC-related mailing lists OCC 7.4 improved Boolean operations a lot. Therefore I think this improved also FreeCAD for some users (like me for example :) ). Do you have any sample data on which we can do a performance analyse with both version of opencascade??

OCC 7.4 is already compiled and ready.
Now i am trying to compile FC against occ 7.4. But i think i have to compile netgen against occ 7.4 too. We will see...

@apeltauer is it possible to update the Libpack to OCC 7.4? Of course it is. But i had some trouble when i was trying to build against occ 7.4 some while ago. See this thread https://forum.freecadweb.org/viewtopic.php?f=42&t=39157&start=20 I can try again to use occ 7.4, i hope all the depe...

I don't think including external executables is correct....

I am 100% with this.
But maybe we can start to create a pack where we can store all needed 3rd party executables?!?
