These errors exist in QGLViewerWidget.obj

QGLViewerWidget.obj:-1: error: LNK2019: unresolved external symbol __imp_glutWireTeapot referenced in function "protected: virtual void __cdecl QGLViewerWidget::draw_scene(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)"

QGLViewerWidget.obj:-1: error: LNK2019: unresolved external symbol __imp_glutSolidTeapot referenced in function "protected: virtual void __cdecl QGLViewerWidget::draw_scene(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)"

While this error exists in meshviewer.obj

meshviewer.obj:-1: error: LNK2019: unresolved external symbol __imp___glutInitWithExit referenced in function glutInit_ATEXIT_HACK

What I have tried:

So I have changed the following lines:

LIBS += \
    /usr/local/lib/libOpenMeshCore.so  \
    /usr/local/lib/libOpenMeshTools.so

LIBS += \
    -lglut -lGLU

to:

LIBS += \
    -lglut32 -lOpenMeshCored -lOpenMeshToolsd

I have glut.lib , OpenMeshCored.lib, and OpenMeshToolsd.lib and move to C:/Qt/.../lib folder but I don't have glu.lib. I tried to download online but it is not available and didn't found any. Please help alternative solutions for the error.

If you are trying to call a function in a library that does not exist then you will continue to receive this error message. Change the code so it does not try to reference non-existent functions.

No, I'm not trying to call any function. Just what I have mentioned, what I have only done is changed the

LIBS += \
/usr/local/lib/libOpenMeshCore.so \
/usr/local/lib/libOpenMeshTools.so

LIBS += \
-lglut -lGLU

to

LIBS += \
-lglut32 -lOpenMeshCored -lOpenMeshToolsd
