Hello Carlos,

Thanks for reporting these issues.

There are many ways to fix this issue, for instance by adding in the
#else clause:

void Graphic3d_WNTGraphicDevice::SetGraphicDriver (const
Standard_CString theGraphicLib)
{
Aspect_GraphicDeviceDefinitionError::Raise("SetGraphicDriver is
not available when using static libraries");
}

I am not familiar with Windows and cannot test, but you may try to
edit inc/InterfaceGraphic_WNT.hxx and replace

#ifdef __cplusplus
extern "C" {
#endif /* __cplusplus */

__declspec( dllimport ) long InterfaceGraphic_RealizePalette ( HDC,
HPALETTE, BOOL, BOOL );

#ifdef __cplusplus
}
#endif /* __cplusplus */

by

#include <Standard_Macro.hxx>
Standard_IMPORTC long InterfaceGraphic_RealizePalette ( HDC,
HPALETTE, BOOL, BOOL );

I can take a look on this as soon as I get back home :) could you open a bug for this on the meantime?

Thanks Qb, issue #295 is assigned to you ;)

(cross-posted to the bug)

I've added a branch qb/static-fixes with the changes proposed by denis.
Instead of raising an exception I've just called the SetGraphicDriver (), so the user doesn't have to change the code between configurations, it just works.
I had to add #include <Standard_Macro.hxx> in the InterfaceGraphic_WNT.hxx too.

Carlos, could you just test this branch? Visualization in a static configuration has not been tested though, we could use this opportunity to check it. There may be issues with OCAF plugins too.
