Hi @sgrogansgrogan wrote: I realized I must compile vejmaries OCC7 branch then his FreeCAD branch against this. I haven't given up.
I received an update from @vejmarie ... his recent PR has been committed here
https://github.com/FreeCAD/FreeCAD/pull/466
The code has been included into commit #9810.
Any version of FreeCAD with a higher value than that will run the new STEP reader which has the ability to have TBB usage dependent of its activation status at CMake Level ...
So, if I have correctly interpreted the @vejmarie advise, it should be easier to build the main branch with the new OCCT (with TBB support)...
Thx
