[Insight-developers] Sun Compiler

[William A. Hoffman]

I think the better approach would be to qualify the name:

template <int VD>
struct A
{
static const int Dimension = VD;
void Method(double v[Dimension]);
};

template <int VD> void A<VD>::Method(double v[A::Dimension]) {}

The above code works on gcc 3.4, como, SGI CC, VS 6,7,7.1, and borland.
If you want to try it on your favorite compiler, then let me know if it
does not work.
