I'm trying to compile scummvm 1.6.0 with the mipspro compilers. Right now, I'm stuck with their singleton hack. The error I'm getting is
Code:
cc-3234 CC: ERROR File = graphics/fonts/ttf.cpp, Line = 479
Explicit specialization of member
"Common::Singleton<Graphics::TTFLibrary>::_singleton" must precede
its first use.

template<> Graphics::TTFLibrary *Singleton<Graphics::TTFLibrary>::_singleton = 0;

Although the constuct is supposed to prevent this exact error:
Code:
/**
* Note that you need to use this macro from the Common namespace.
*
* This is because C++ requires initial explicit specialization
* to be placed in the same namespace as the template.
*/
#define DECLARE_SINGLETON(T) \
template<> T *Singleton<T>::_singleton = 0

} // End of namespace Common
Does anyone have an Idea how to work around this for MIPSPro C++?

Wrong namespace, maybe?

The namespace is actually correct:
Code:
namespace Common {
DECLARE_SINGLETON(Graphics::TTFLibrary);
} // End of namespace Common

#endif
It turns out that MIPSPro is way more picky about this, and just shufflihg the DECLARE_SINGLETON just after the declaration of the :TTFLibrary makes this file compileable.
