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*

And /path/to/dumuxfolder/mymodule/app/ccs_biofilm.hh:35 is :

And /path/to/dumuxfolder/mymodule/app/ccs_biofilm.hh:41:0 is :

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
