I am using some older libraries known as glui.lib I am getting an compiler error: I have included all the header files and linked in all the libraries.

Error C2252 an explicit instantiation of a template can only occur at namespace scope Project80 c:\users\owner\desktop\glui-2.36\glui-2.36\src\include\gl\glui.h 1718

Which version of GLUI are you using?

Where did you get it?

Which compiler are you using? What version?

Actually, what I do is I add the GLUI source into my solution, and build it from scratch. No libs or dlls required. It only needs to be compiled once.
