I already have OpenFOAM 3.0.1 installed and recently successfully installed foam-extend 3.2 on ubuntu 15.10. I have "partitioned" my terminal with the alias command of301 and fe32. I am able to solve the tutorials in foam-extend and view them in paraview.

Now the problem comes when I try to compile any code. I modified icoFoam as in this thread:

http://www.cfd-online.com/Forums/ope...s-2-1-0-a.html

to simulate a dns turbulent channel flow, but I get an error when I compile the new code, icoDNS. Keep in mind that I get these "unused variables" even when I rename a solver without changing any code and try compiling. When compiling I change the Make/files by adding _USER_ and renaming my .C

icoDNS still compiled since ubuntu was able to recognize icoDNS -help

I renamed dnsFoam to dnsFoamdns and compiled it without changing a line of code and still got those errors. I solved boxTurb16 with dnsFoamdns and it solved perfectly. So I am guessing that the "unused variables" aren't an issue.

I went ahead to solve channel395 with icoDNS and got this error:
