These 3 types are defined in the GLC_lib file glext/glext.h . I cannot
see an obvious reason why you would get these errors. Perhaps your
download is corrupt? Try downloading again and comparing this header.

This is true for Qt 4.4.3 which Sujan is trying to use, but this
overload does indeed exist in Qt 4.5.

Sujan, I have successfully built GLC_lib 1.2.0 on Linux with Qt 4.5.3
However, it cannot be built with 4.4.3 because of this issue (and
possibly more). If I try to build with 4.4.3 then I get this error
concerning QList, however I do not get the errors regarding undefined
types above, which is why I suggest there may be something wrong with
your download of GLC_lib.
