Sun Studio C++ v5.3 adding complex gives errors

Question

If anyone can privide info on the following issue I would greatly appreciate it.. I have a simple test app that does not compile. This is with Sun Studion C++ v5.3 (I think then called Sun Workshop Pro) on a Solaris 5.8 machine.
#include <complex>
using namespace std;
int main()
  complex<int> a(1, 2);
  complex<int> b(3, 4);
  complex<int> c;
  c = a + b;
  cout << "Answer: " << c << endl;
  return 0;
}When compiling I get the following error:
/opt/SUNWspro/WS6U2/include/CC/Cstd/complex Line 1006: Error The operation "std::complex<int> += const std::complex<int> is illegal
sol_cpx.cc Line 10 Where: While instantiating std::complex<int>+ ( const std::complex<int>, const std::complex<int> )
sol_cpx.cc Line 10 Where: Instantiated from non-template code
Are there any compiler flags to handle this or is there an update I can get to fix this? Any help would be much appreciated since I'm clueless. Thank you!

Answer 1

complex<int> is not supported. The only specializations of type complex are float, double, and long double.
The suggestion to try stlport won't work with C++ 5.3.
We began supplying stlport with C++ 5.4.
C++ 5.3 has been declared End Of Life, and only limited support is available for it. You can download a copy of the current release, Sun Studio 10, and try it free for 60 days.
