Hello Phil,

I was trying to build SIP 3.3 and PyQt 3.3, with Python 2.7.1 and was able to build SIP successfully.
Then, I tried building PyQt, where, the first module ie qt module got build successfully.
but there was a linking error, while building qtgl module as follows

sipqtglQGLContext.obj : error LNK2019: unresolved external symbol "private: stat
ic class QGLContext * QGLContext::currentCtx" (?currentCtx at QGLContext@@0PEAV1 at EA
) referenced in function "public: static class QGLContext const * __cdecl QGLCon
text::currentContext(void)" (?currentContext at QGLContext@@SAPEBV1 at XZ)
r:\bld\release\python\win64\Lib\site-packages\libqtglc.pyd : fatal error LNK1120
: 1 unresolved externals
NMAKE : fatal error U1077: 'link' : return code '0x460'
NMAKE : fatal error U1077: '"R:\imports\qt\qt3\bin\nmake.exe"' : return code '0x

I checked out qgl.h and found that QGLContext had following definition 

class QM_EXPORT_OPENGL QGLContext : public QGL
   	// some member functions
    static const QGLContext*	currentContext();
	// some member functions

	// some member functions
    static QGLContext*	currentCtx;

What could be the possible reason for this ?

Thanks a lot for helping
