C++ compiler problems with FC2

Can you post an example? I've written and compiled well over 3000 source
files using gcc 3.3.3 and 3.4 without a hitch on the headers.

You should never use 2.96 for C++ - it's awful! Leave that to the debian
crew.

Without seeing code, no idea.

Does this compile for you

#include <iostream>
#include <cmath>

using namespace std;

int main()
{
  cout << "sine 63 = " << sin(63) << endl;
  cout << "log to the base 10 of 54 = " << log10(54) << endl;
  double quick = (sin(53) * sqrt(14.3443) + tanh(22)) / log(61.444);
  cout << "quick = " << quick << endl;
}

This should give you...

sine 63 = 0.167356
log to the base 10 of 54 = 1.80618
quick = 0.606956

Very silly test, but should work without a hitch.

TTFN
