Open CASCADE Technology 7.8.0 released

I noticed that the download page for releases has been updated for 7.8.0. However, there is no link for any testgrid data set like there was for previous releases. Is that something that just hasn't been done yet or ... what? I realize the testing data is probably difficult to deal with as it is split between proprietary and open files, but it would be nice is the open files could be hosted is some kind of public repo.

Hi,

After upgrading Open cascade from 7.7.0 to 7.8.0 I can't compile my library any more.

I've changed my CMakeLists.txt with the new .so libraries for STEP from libTKXDESTEP.so to libTKDESTEP.so

If I recompile my code against Open Cascade 7.7.0 everything compiles fine.

Let me know if you need more input.

Kind regards,

Upgrading from 7.5 to 7.8 my STL importer is broken since it can't find XSDRAWSTLVRML_DataSource anymore. With what is it replaced?
I checked in the git log and can see that it was removed on 19/11/23, checked the reworked mfc samples but could not figure out how the import should be done now.

This is my 7.5 code:

bool CView3DFrame::LoadSTL(LPCTSTR iFilePath, AIS_ListOfInteractive&		aShapes)
{
	Standard_CString		theFileName(iFilePath);

	Handle_Poly_Triangulation					m_mesh; 
	//Message_ProgressRange						hMessageProgress;
	Handle(CTrack_Message_ProgressIndicator)	hMessageProgress = new CTrack_Message_ProgressIndicator(GetShortName(iFilePath), false);
	m_mesh = RWStl::ReadFile(theFileName, hMessageProgress->Start());
	if (m_mesh.IsNull())
		return false;

	hMessageProgress->SetText("Transfer CAD file");
	Handle(MeshVS_Mesh) aMesh = new MeshVS_Mesh();
==>	Handle(XSDRAWSTLVRML_DataSource) aDS = new XSDRAWSTLVRML_DataSource(m_mesh);

	aMesh->SetDataSource(aDS);
	aMesh->AddBuilder(new MeshVS_MeshPrsBuilder(aMesh), Standard_True);//False -> No selection

	aMesh->GetDrawer()->SetBoolean(MeshVS_DA_DisplayNodes, Standard_False); //MeshVS_DrawerAttribute
	aMesh->GetDrawer()->SetBoolean(MeshVS_DA_ShowEdges, Standard_False);
	aMesh->GetDrawer()->SetBoolean(MeshVS_DA_SmoothShading, Standard_True);

	Graphic3d_MaterialAspect Material = DEFAULT_MATERIAL;
	aMesh->GetDrawer()->SetMaterial(MeshVS_DA_FrontMaterial, Material);
	aMesh->SetDisplayMode(m_bShadingShaded ? MeshVS_DMF_Shading : MeshVS_DMF_WireFrame); 
 	aMesh->SetHilightMode(MeshVS_DMF_Shading); 
	aMesh->SetMeshSelMethod(MeshVS_MSM_BOX);
	aShapes.Append(aMesh);

	return true;
}
