Hi Marcus,
thanks for the reply.

Still that does not answer why VC7 gives those errors ? From a language
semantics perspective what really is wrong with that line?

Ok that helps, and thanks for the tip.

It just makes it easier. They're pretty easy to set up if you use isual
Studio though, so look it up on the net if compilation times becomes a
problem. (One small tip: stay away from automatic generation, it seldom
works the way you expect.)

I am not using pre-compiled headers for my build. Is it necessary to use
them to avoid the warnings? I am not very familiar with PCH, can you
point me to some links /references which talk in detail about PCH (Sorry
for asking windows specific question in this forum but I guess things
are related :-) ) ?
#pragma warning(disable : 4275 4267 4244 4231)
AFAIK doing above will only disable the warning. Isn't there a clean and
right way of doing this ? Is this warning ignorable really?
Thanks for the reply,

Hi Divick,
I have wrapped my osg-includes (which I put into a PCH) with:
#pragma warning(disable : 4275 4267 4244 4231)
#pragma warning(push, 1)
...
#pragma warning(pop)
This takes care of most of these issues.

Hi all,
I have written an application which uses OpenSG for rendering.
When I compile my application, I get lots of compilation warnings. I am
using VC.NET2003 compiler (i.e. VC7) on Window XP. The type of warnings
that are shown by VC7 are shown below:
c:\trees\3dviewerapp\thirdparty\OpenSG\include\OpenSG\OSGSFBaseTypes.h(66)
: warning C4231: nonstandard extension used : 'extern' before template
explicit instantiation
And the line in OSGSFBaseTypes.h at 66 is shown below
#ifndef OSG_COMPILEFIELDINST
OSG_DLLEXPORT_DECL1(SField, std::string, OSG_BASE_DLLTMPLMAPPING) //is
the line 66
#endif
There are almost 242 such warnings and all of them point to some line
starting with OSG_DLLEXPORT_DECL1.
Is there some preprocessor declaration that I am missing or is it
something else?
Thanks,
Divick
