Hi all-
I'm trying to compile an app that links to OCC on MinGW. When linking I get the following error:
g++ -c -g -g -frtti -fexceptions -Wall -DUNICODE -DQT_LARGEFILE_SUPPORT -D_DEBUG -DWNT -DWIN32 -D_WINDOWS -DQT_NEEDS_QMAIN -DQT_DLL -DQT_GUI_LIB -DQT_CORE_LIB -DQT_THREAD

C:/occ/win32/ros/inc/Standard_Real.hxx:31: error: duplicate `extern'
The error are pointing to the places in Standard_Real.hxx with the following lines:
#ifdef WNT
extern "C" __Standard_API Standard_Real PI;
extern "C" __Standard_API Standard_Real PI180;
extern "C" __Standard_API Standard_Real Standard_PI;
extern "C" __Standard_API Standard_Real Standard_PI180;
#else
I can't determine where these externs are also being defined. Any help would be greatly appreciated.
Thanks.

They're defined in Standard_Real.cxx strangely enough.
Have you through about using Qt/Win on sourceforge to "coerce" the GPL'd Qt4 onto VS2003/2005.

Pete-
I've tried it, but couldn't get it working after several hours, then began to wonder why I was doing it in the first place if it worked just fine on MinGW. Perhaps this is my reason.
Thanks.

I had no problem with this - what wouldn't work? I may be able to help.
As with some of the other responses, OCC is not supported on MinGW and this may be at the heart of your problem.

If you compile using g++ then you probably should not define WNT macro. Try instead LINUX.

Ok, I tried defining LINUX instead but it seemed to not want to link to anything anymore. I something like this:

Has no one ever compiled OCC with Qt on MinGW? That would seem amazing. I think there's something we're missing here.
Thanks, Bearloga.
