Hej, thanks for the reply!
Yes the header was missing but now the compiler is unable to find it:

dolfin_headers.h:65: Warning(201): Unable to find
'dolfin/ElasticityUpdatedSolver.h'

In any case, I think that the guide I linked above is wrong in the
beginning when it says to create dolfin_mylib.h in src/kernel/mylib, it
should be instead src/kernel/mylib/dolfin. I followed rest of the guide,
but I can't get rid of this warning.

Ok at the moment I'm just trying to polish elasticityupdatedsolver.cpp in
order to move some of the functionalities I have implemented caotically in
python there, such as the classes imported using import_header(). I will
see then if it's possible to update to dolfin 0.7.0 or if I have to go
back to 0.6.4.
