Summary: Cannot define static template struct member
Product: gcc
Version: tree-ssa
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: schnetter at uni-tuebingen dot de
CC: gcc-bugs at gcc dot gnu dot org
GCC host triplet: i686-pc-linux-gnu
I cannot define static members of template structs. The code
template<int D>
struct x {
static int a;
};
int x<0>::a;
leads to the error message
tmp.cc:5: error: too few template-parameter-lists
The same code compiles fine with g++ 3.3.1.

That's because your code is invalid. You need to write
template <> int x<0>::a;

The proposed solution, namely adding "template<>" in front of the definition
of the variable a, does not solve the problem. The compiler now accepts the
construct, but the object file does not contain a definition of the variable
a. (The syntax reminds me of a template specialisation, which is not at all
what I want.)

That is because you need to instantiate the template to get the variable emitted (or use it if on a
target that supports weak):
template<int D>
struct x {
static int a;
};
template struct x<0>;
template <> int x<0>::a;

You are right, the syntax I showed is a declaration of an explicit specialization. You
need to add an initializer to make it a definition.
