Hello
@easternbun ,
I haven’t seen this error though use TKV3d library freely. Now I use OpenCascade 7.6.0.
First what I did to check your case is compared sources between version 7.6.0 and 7.7.0.
There is a difference in this code, related to issue
https://tracker.dev.opencascade.org/view.php?id=33054
In 7.6.0 we have:
C++:
Standard_EXPORT virtual void DumpJson (Standard_OStream& theOStream, Standard_Integer theDepth = -1) const Standard_OVERRIDE;
In 7.7.0 we have:
C++:
inline virtual void DumpJson (Standard_OStream& theOStream, Standard_Integer theDepth = -1) const Standard_OVERRIDE;
The latest code looks more correct, but have no ‘inline’ word in ‘.lxx’ implementation of ‘DumpJson’ (as similar implementations in ‘.lxx’ have). May be, it’s the reason?
If you compile OCCT, it’s worth to add this key ‘inline’ into ‘.lxx’ (or restore export decaration), if you just load ready release of OpenCascade, it’s worth to try 7.6.0 release to check whether this error exists with it.
By the way, what platform you use to compile your program? It’s a strange error because, as I know, OpenCascade library is tested thoroughly, even with own products based on it.
