Problem with cpp-Expression

Question

Hello,

I'm working with my code and i figured out that it has problem with the c++ expression defined in it.

class Conductivity : public Expression

{

public:

// Create expression with 4 components

  Conductivity() : Expression(4) {}

// Function for evaluating expression on each cell

  //void eval(Array& values, const Data& data) const

  //void eval(Array& values, const Array& x,  const ufc::cell& cell) const

  {

    const uint D = cell.topological_dimension;

    const uint cell_index = cell.entity_indices[D][0];

    values[0] = (c00)[cell_index];

    values[1] = (c11)[cell_index];

    values[2] = (c22)[cell_index];

    values[3] = (c33)[cell_index];

    }

// The data stored in mesh functions

  boost::shared_ptr<MeshFunction > c00;

  boost::shared_ptr<MeshFunction > c11;

  boost::shared_ptr<MeshFunction > c22;

  boost::shared_ptr<MeshFunction > c33;

};

"""

c = Expression(cppcode=conductivity_code)

The error I get reads:

    In instant.recompile: The module did not compile with command 'make VERBOSE=1', see '/home/fenics/.instant/error/dolfin_compile_code_12f06d08e034a5c9baf508b1be68a57da59ab1e7/compile.log'

I've trying to find a solution from other threads but nothing seems to solve my problem.

Thanks in advance for any help.

Cheers

Did you look in the file:

/home/fenics/.instant/error/dolfin_compile_code_12f06d08e034a5c9baf508b1be68a57da59ab1e7/compile.log

as suggested by the compiler?

Hi Chris,

Yes, and I think this is where the problem is:

recent versions of dolfin use std::shared_ptr not boost::shared_ptr. Which version are you using?

---

1.6.0, but this was an old code and that's why is was not working (I had to fix other things as well).

Anyways, all good now, it works!

Many thanks!
