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,
Divick

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
