Compiling GLUI library, VS2010 gives me a weird namespace error

Question

I've got an OpenGL project for a class I'm in, and it's based on GLUI. The provided GLUI library won't work which is why I'm trying to compile it myself. So, I downloaded the source code from SourceForge and try to compile the _glui library. It gives me this, and I can't find any information on it:

etc, etc etc

I look at the glui.h source file, and lines 1718 and 1719 have this:

#ifdef _MSC_VER
// Explicit template instantiation needed for dll
template class GLUIAPI std::allocator<GLUI_String>;
template class GLUIAPI std::vector<GLUI_String, std::allocator<GLUI_String> >;
#endif

Anyone seen this before?

Answer 1

I just come across this problem. then I do following,you can try.

(1) download the lastest vision from gib.
(2) use vs2010 build it.
(3) you will come across the problem

#ifdef _MSC_VER
// Explicit template instantiation needed for dll
template class GLUIAPI std::allocator<GLUI_String>;
template class GLUIAPI std::vector<GLUI_String, std::allocator<GLUI_String> >;
#endif

just get the code out of class, rebuild again.
(4) you will generate glui.lib.
(5) use the glui.lib,and the glui.h

Answer 2

You cannot explicitly instantiate a template inside a function or a class. try moving it outside the function or class. Or is it a library?
