[Boost-users] [math/special_functions] newbie question

From: Sakaie, Ken (sakaiek_at_[hidden])

I did the following 'hello-world'-level test of the factorial function and get the following error.

> cat test.cpp

#include "boost/math/special_functions/factorials.hpp"
int main()
{
        unsigned int i = 6;
        printf("%d\n", boost::math::factorial(i));
}

> g++ -I/home/sakaiek/ext/src/boost_1_35_0/ test.cpp

test.cpp: In function ‘int main()’:
test.cpp:5: error: no matching function for call to ‘factorial(unsigned int&)’

I think I set up the include directory correctly:
> ls /home/sakaiek/ext/src/boost_1_35_0/boost/math/special_functions

acosh.hpp   beta.hpp      detail        ellint_3.hpp   ellint_rj.hpp   fpclassify.hpp  laguerre.hpp  math_fwd.hpp  sinhc.hpp
asinh.hpp   binomial.hpp  digamma.hpp   ellint_rc.hpp  erf.hpp         gamma.hpp       lanczos.hpp   powm1.hpp     sin_pi.hpp
atanh.hpp   cbrt.hpp      ellint_1.hpp  ellint_rd.hpp  expm1.hpp       hermite.hpp     legendre.hpp  sign.hpp      spherical_harmonic.hpp

Any help would be greatly appreciated.

Thanks!
