Hello all,
I have tried to build OSG 1.1 in static configuration with VC8.
It worked well until I tried to link some static built plugins.
If we take ive plugin
It seems that the global:
RegisterReaderWriterProxy<IVEReaderWriter> g_IVEReaderWriterProxy;
is deadcode stripped because there is no reference to it in the application.
So the ive ReaderWriter is never registered.
To solve the problem
1) I added this code to ReaderWriterIVE.cpp :
#ifdef OSG_LIBRARY_STATIC
void* RegisterIVE()
{
return (void*)&g_IVEReaderWriterProxy;
}
#endif //OSG_LIBRARY_STATIC
2) I called this function from the application
This prevents g_IVEReaderWriterProxy from being deadcode stripped and
things work well.
Is there another way to avoid that kind of deadcode stripping (I know
for example that there is a specific pragma in some compilers, but I
didn't find anything in VC8) ?
If not, I am sure there is a more elegant way to implement my trick but
I think that this could be an easy way to allow true use of the OSG
static build with a minimum of change to the code and keeping the spirit
of the plugins.
I would be interested in having your feedback.
Regards,
Guillaume
