I'm using the MIPSpro Compiler and having trouble defining
a function template (involving array size specifiers as
template arguments) inside a class. The same definition
compiles fine outside the class. I have listed a short
sample code and resulting error messages at the end of
this posting.
Is there a known work-around that fixes this "inside
the class" problem for SGI compilers -- short of
upgrading beyond v7.2.1?
One final note, the code below compiles and runs
correctly with g++. Thanks.
//////////////// junk.C ////////////////
#include <iostream.h>
template <typename T, size_t N>
size_t count1(T (&array)[N] )
{
return N;
}
class A {
public:
template <typename T, size_t N> size_t count2(T (&array)[N]);
};
template <typename T, size_t N> size_t A::count2(T (&array)[N])
{
return N;
}
int main()
{
A a;
int b[3];
cerr << count1(b) << " " << a.count2(b) << endl;
return 0;
}
