Maybe because you forgot to put a semicolon after the enum definition, this works for me in LiveWorkSpace:

#include 

enum E
{
   TYPE_FLOAT,
   TYPE_CHAR,
   TYPE_INT
} ;

template struct GetE;

template<> struct GetE { static constexpr E type = TYPE_FLOAT; };
template<> struct GetE { static constexpr E type = TYPE_CHAR; };
template<> struct GetE { static constexpr E type = TYPE_INT; };

int main()
{
    std::cout << GetE::type << std::endl ;
}
