hi,

I am using OpenFOAM with QtCreator. Currently I have to implement some Integralfunctions with several input parameters like:

class IntegralFunctionB
{
private:
    double x;
    double y;

public:
    IntegralFunctionB(double a, double b)
    {
        x = a;
        y = b;
    }

    double operator()(double d) const
    {
        return pow(y,4)*(6.4/d)*exp(-(4.5*pow(2.0*pow(d,3.0)-pow(x,3.0),2.0))/pow(x,2.0));
    }
};

I get the error:

/home/USER/SolverNEW/NEW/SourceTermIntegralFunctions/IntegralFunctionB.H:16: error: call of overloaded ‘pow(double&, const double&)’ is ambiguous
candidates are:
/usr/include/i386-linux-gnu/bits/mathcalls.h:155: double pow(double, double)

Therefore I've added the filepath to...

... the Make/options file:

-Iusr/include/i386-linux-gnu/bits

... the include file of the IDE (Qt Creator):

/usr/include/i386-linux-gnu/bits

For the include I tried

#include "mathcalls.h"
#include <mathcalls.h>

but when building my project I get the error:

/home/USER/SolverNEW/multiphaseEulerFoamNEW.C:46: error: mathcalls.h:
No such file or directory

Please note also that in "usr/include/i386-linux-gnu/bits" only root has full access, others are just authorised to "access files", but setting the permissions for other to "read and write" does not change the output.

How can I solve this problem since I need to use the "pow(double,double)" method?

EDIT:

If I use Foam:ow(....) the code compiles fine, but I ve only found some kind of Foam:ow(double,double) here:

https://github.com/OpenFOAM/OpenFOAM.../doubleFloat.H

Is this the method called when doing Foam:ow(...) and will it work for Foam:ow(double,double)?
