Dear DuMuX community,
I am running DuMuX release/3.0.
*I switched* an app using the 2pncNIMin model *from CCTpfa* spatial
disctretization method *to the Box* discretization *method*.
The application runs fine, but I always get this *warning* at compile
time :
*Scanning dependencies of target ccs_biofilm*

Note that /path/to/dumuxfolder/mymodule/app/ccs_biofilm.cc:54 is :
#include "ccs_biofilm.hh"
And /path/to/dumuxfolder/mymodule/app/ccs_biofilm.hh:35 is :
#include <dumux/porousmediumflow/2pncmin/model.hh>
And /path/to/dumuxfolder/mymodule/app/ccs_biofilm.hh:41:0 is :
#include <dumux/discretization/evalsolution.hh>
I tried to look around in the files but this is probably too technical
for me.
Is this warning somehow familiar to you ? Can I ignore it without any
problem or should I try to solve that ?
Best regards,
Joan
