The problem only occurs when trying to link the debug version of OpenSG1.8. The
release version links fine.
I have no clue, but I guess vs2010 has some default linker settings (that are
different to the default settings in vs2005) when applying the /DEBUG flag...
I fixed the link problem by introducing I new struct called
FieldTraitsIntegralRecurseMapper1, but I have no idea if this solution is
correct and smart. Patch is attached.
hmm, the FieldDataTraits1<QBit> in OSGQBit.h is missing a
OSG_SYSTEMLIB_DLLMAPPING annotation. I'm wondering if that somehow
causes the compiler to create a separate instantiation of
FieldTraitsIntegralRecurseMapper<UInt8> instead of pulling in the one
from OSGBase.dll [1]?
Would you mind giving the attached a try and see if it fixes the problem?
Cheers,
Carsten
[1] I *think* that is the underlying problem: there is a second
instantiation of FieldTraitsIntegralRecurseMapper<UInt8> created that
conflicts with the one from OSGBase.dll - if that's the case, the
(puzzling to me) question is of course why that happens ;)
