Hello, I recently installed Fedora 22 and I decided to use boost 1.59.0. I also have a little server with Centos 7 on it. On both system, I installed boost 1.58.0. I also installed the Intel cluster studio XE 2016 on each machine. I can compile (and run) with no problem my code on the Centos 7 but I can not compile it under fedora 22. The relevant lines of code are: void GABAB::compCumSum(double* out,double T_in,double dur)

{ double dt=0.01; int NStep=(int) floor(dur/dt);

int tmpstartInd=startInd;

startInd=0;

StateVector x(2 * NState);

controlled_runge_kutta< runge_kutta_cash_karp54 < StateVector, double, StateVector, double, vector_space_algebra, mkl_operations > > stepper_cumsum;

compInitState(x, 0.0, 0.0);

for (int ii = 0; ii < NState; ii++) x[ ii + NState ] = 0.0;

for (int ii = 0; ii < NState; ii++) out[ii] = x[ii];

setInput(T_in, T_in);

cumsum_GABAB tmp(*this);

size_t steps = integrate_adaptive( stepper_cumsum, tmp , x , 0.0 , dur , dt );

for (int ii = 0; ii < NState; ii++) out[ii] = x[ii + NState];

startInd=tmpstartInd; }

StateVector is a typedef in another header file: typedef boost::numeric::ublas::vector< double > StateVector; If I comment the line starting with "integrate_adaptive(...", I can compile the code. Otherwise, I got a tons of errors, starting with: /usr/include/c++/5.1.1/functional(78): error: class

"boost::numeric::odeint::controlled_runge_kutta<boost::numeric::odeint::runge_kutta_dopri5<StateVector, double, StateVector, double, boost::numeric::odeint::vector_space_algebra, boost::numeric::odeint::default_operations, boost::numeric::odeint::initially_resizer>, boost::numeric::odeint::default_error_checker<double, boost::numeric::odeint::vector_space_algebra, boost::numeric::odeint::default_operations>, boost::numeric::odeint::initially_resizer, boost::numeric::odeint::explicit_error_stepper_fsal_tag>" has no member "result_type" { typedef typename _Functor::result_type result_type; };

I emphasize the fact that the code can easily be compiled under Centos 7 with the same installation procedure of boost and the intel cluster xe suite. Any clue of what is happening?
