Issues building OpenCASCADE

[Alex Teti]

I've downloaded OpenCASCADE for Windows, and included it in the PATH. After that, I followed the install guide for CMAKE, turning it on and then supplying the directory of the  OpenCASCADEConfig.cmake file.

Everything seemed to go well until I went to build and got some errors. I attached a screenshot of the errors from Visual Studio. 

It seems that BRepAdaptor_HSurface.hxx and ChronoEngine_cascade.lib are missing, for some reason. 

I used PowerShell to quickly do a recursive search through the chrono SDK directory and confirmed that BRepAdaptor_HSurface.hxx is not present. 

[Alex Teti]

AHA! I realized that BRepAdaptor_HSurface.hxx  is actually located within OpenCASCADE's SDK, not inside ProjectChrono.

Is this a compatibility problem? I am using OpenCASCADE 7.6.0; the documentation for installation and use with Chrono said that versions less than 7.4.0 are incompatible, but is it the case that newer versions of OpenCASCADE are incompatible too?

[Radu Serban]

Alex, that is indeed the case. OpenCascade changed its API in 7.5 and the Chrono interface still uses their older API.  We'll make that clear on the Chrono documentation. You have to use OCC 7.4.0.
