SYMPTOMS
The compiler generates the following errors when compiling the sample code shown below (the code initializes a static data member of a template class):
RESOLUTION
To work around this problem, use the assignment operator when initializing the static data member of a template class.
STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
This problem was corrected in Microsoft Visual C++ .NET.
MORE INFORMATION
The following sample code demonstrates the problem and the workaround:
/* Compile options needed: none
*/
#include <stdio.h>
class Register {
public:
Register( const char* class_name )
{ printf("In Register ctor for class %s.\n", class_name); }
~Register()
{ printf("In Register dtor.\n"); }
};
template<class T>
class Base {
public:
static Register r;
};
template<class T>
Register Base<T>::r( "Base<T>" ); //Cause of C2059, C2063 and C2040
// To work around the problem, comment the line above and
// uncomment the following line:
// Register Base<T>::r = Register("Base<T>");
int main() {
return 0;
}
