Dear all,

I am having difficulties in understanding how wmake works and how I can correctly compile an application to include subdirectories in the application folder.

I was experimenting using a rather simple example, which I named test_wmake utility. For this I employed the following file structure:

Folder test_utility
    test_wmake.C
    -Folder Make
        -files
        -options
    -Folder Classes
        classA.H
        classA.C
        -Folder classB
            classB.H
            classB.C

The files were as follows:

test_wmake.C:

#include "fvCFD.H"
#include "Classes/classA.H"

int main(int argc, char *argv[])
{
    
    A A_(2.0);
    
    Info << A_.f(2.0) << endl;
    
    return 0;
}

Make/files:

test_wmake.C
Classes/classA.C
Classes/classB/classB.C

EXE = $(FOAM_USER_APPBIN)/test_wmake

Make/options:

EXE_INC = \
    -I$(LIB_SRC)/finiteVolume/lnInclude \

EXE_LIBS = \
    -lfiniteVolume \
    -lgenericPatchFields

Classes/classA.H:

#ifndef CLASSA_H
#define CLASSA_H

#include "classB/classB.H"

namespace Foam
{
class A
{
    public:
        A(const double inX);
        ~A();
        
        double f(const double x) const;
        
    private:
        mutable B B_;
};
}
#endif // CLASSA_H

Classes/classA.C:

#include "classA.H"

namespace Foam
{
    A::A(const double inX) : B_(inX) {}
    A::~A() {}
    
    double A::f(const double x) const
    {
        return B_.f(x);
    }
    
}

Classes/classB/classB.H

#ifndef CLASSB_H
#define CLASSB_H

namespace Foam
{
class B
{
    public:
        B(const double inY);
        ~B();
        
        double f(const double x) const;
        
    private:
        double y_;
};

}

#endif // CLASSB_H

Classes/classB/classB.C:

#include "classB.H"

namespace Foam
{
    B::B(const double inY) : y_(inY) {}
    B::~B() {}
    
    double B::f(const double x) const
    {
        return x*y_;
    }
    
}

when running wmake &> log, I get the following:

The application compiles correctly and when running test_wmake I get the correct answer. I do not understand though the very first error message "could not open file classB/classB.H for source file test_wmake.C due to No such file or directory" and how I can avoid this.

I am using openFoam 2.3.x which I compiled in ubuntru 14.04 using the Gcc++0x 4.8.2 compiler.

Any thoughts are mostly welcome!
