It seems that gcc does not allow this kind of template argument deduction:

template <int N> void f(int a[N]) { for (int i = 0; i < N; i++) cout << a[i] << " "; cout << endl; }

int main() { int a[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};

f(a); }

The error message is:

error: no matching function for call to `f(int[10])'

...

I would like to know how to fix this. Is there any workaround? Or if I am missing something?

You're missing something. Your declaration of f is equivalent to:

template <int N> void f(int* a);

try:

template <int N> void f(int a(&)[N])

^^^

instead.

Hmm - that didn't work for me. But with the above hint I made the following compile and function with both VC 7.1 and gcc. template <int N> void f(int (& a)[N]) ^^^^ I had never been able to get demo_fast_binary_archive but could never figure out the reason - Mystery Solved ! Robert Ramey
