Hi again,
Thanks for your long explanations, sorry if I was a little dimwitted...
Unfortunately I didn't get any improvement, and I don't understand some of
the patterns used in the reader (maybe no wonder at 6000 lines ;-)
The StringConvertable and the bHasParent was already set by the *Fields.h
template code, so that point didn't change.
The typedef SField<AudioClipPtr>... goes according to GenericAttPtr, so I
placed that part exactly direct under that in the VRMLNodeDesc.h
The Inlines of OSGSFieldTypeDef.inl and MFieldTypeDef are also already in
the VRMLNodeDesc.cpp, so should be compiled in.
At last the
DataType FieldDataTraits<AudioClipPtr>::_type("AudioClipPtr",
"NodeCorePtr");
I put as the last line right after the same call for GenericAttPtr, so
this should be in the object too and therefore in the lib.
What can I test else? I'm a little short of ideas...
Thanks a lot.
Best regards, Daniel
