Marco!
This is caused by the new automatic parsing of dependencies for
compiled_modules in Python. It was added so a minimum of dependencies
are dragged into the compilation, reducing the compilation time
considerably. If you instead of #including "dolfin.h" only #include
"dolfin/fem/GenericDofMap.h", the compilation time was almost halved on
my laptop.
Unfortunately it is only the public interface which get parsed and
included in dependency generation. This means that #include statements
for GenericDofMap is not generated. It has to be manually included...
Because of the nice speedups for the compilation time I am inclined to
keep the somewhat flawed automatic dependencies checks we have now.
I do agree that your case should be supported in a better way than
adding it as a hack, as you did. Another hack is to introduce a dummy
public dependency:
class Delta1 : public Expression
{
public:
GenericDofMap* dummy;
Delta1() : Expression() {}
...
which is also sub optimal as it is non-intuitive.
What we probably need is to expose some more compile options to the
Expression interface so you can do:
Expression(cppcode_d1, element=DGe, \
system_headers=["dolfin/fem/GenericDofMap.h"])
Other opinions?
