New question #94139 on DOLFIN:
https://answers.launchpad.net/dolfin/+question/94139

I had my program running, but I had to update to the new release of dolfin to fix a problem I had with dolfin::Functions. Therefore, this problem is a direct result of using the new version. I was using 0.9.4 which I had cloned around the beging of August prior to this. 

This is my error msg:

CSolver.h:200: error: no matching function for call to ‘dolfin::VariationalProblem::VariationalProblem(Laplace::BilinearForm&, Laplace::LinearForm&, std::vector<dolfin::BoundaryCondition*, std::allocator<dolfin::BoundaryCondition*> >&, const dolfin::MeshFunction<unsigned int>*, const dolfin::MeshFunction<unsigned int>*, const dolfin::MeshFunction<unsigned int>*)’

As far as I can see, the only differences between the one I'm using, and the one I want to use are the const
Before updating my version I was using it like so:

dolfin::VariationalProblem problem(a, L, bcs, 0, &CSD, 0);

and it was compiling and running. Since updating I have changed to:

dolfin::VariationalProblem problem(a, L, bcs, &zero, &CSD, &zero);

CSD and zero are both MeshFunctions declared like so:

dim = cathode->topology().dim() - 1;
const dolfin::MeshFunction<unsigned int> CSD(*cathode, dim);
const dolfin::MeshFunction<unsigned int> zero(*cathode, dim);

I have made both of them const. since updating in a effort to get it to compile. I have a feeling I'm missing something really simple, but I can't seem to figure it out. Any help would be appreciated.
Thank you very much

Phil
