Hello,
I am trying to use STEPCAFControl_Writer to write a document as a step file. When I compiled the program, cmake outputs the following error:
$ cmake --build . Scanning dependencies of target splitStep [ 25%] Building CXX object CMakeFiles/splitStep.dir/testArea/splitStep.cpp.o In file included from /home/kaiwen/ompl-assembly-planner/testArea/splitStep.cpp:2: /usr/include/opencascade/STEPCAFControl_Writer.hxx:236:3: error: ‘NCollection_Vector’ does not name a type; did you mean ‘NCollection_Vec4’? 236 | NCollection_Vector<Handle(StepRepr_RepresentationItem)> myGDTAnnotations; | ^~~~~~~~~~~~~~~~~~ | NCollection_Vec4 make[2]: *** [CMakeFiles/splitStep.dir/build.make:63: CMakeFiles/splitStep.dir/testArea/splitStep.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:78: CMakeFiles/splitStep.dir/all] Error 2 make: *** [Makefile:84: all] Error 2
I changed the NCollection_Vector to NCollection_Vec4 as the error suggested and then it compiled. The program also manages to write the step file, but then crashes, causing a segmentation fault (core dumped). I assume this is not a valid fix, but I am clueless how to fix it otherwise.
Any help is greatly appreciated. Thank you!
Here is the Terminal output of the program:
******************************************************************* ****** Statistics on Transfer (Write) ****** ******************************************************************* ****** Transfer Mode = 0 I.E. As Is ****** ****** Transferring Shape, ShapeType = 2 ****** ** WorkSession : Sending all data Step File Name : ../solutions/splitPart.stp(1394 ents) Write Done Segmentation fault (core dumped)

Hello,
It looks not normal. Can you share a version of occt? And gcc version.
As a hot solution, can you add #include <NCollection_Vector.hxx> in your file before including writer?
Best regards, Dmitrii.

Including NCollection_Vector fixed the problem. Thank you very much!

Thank you. We will fix it on our side in the next release.
Best regards, Dmitrii.
