Hi, guys
I was trying to add temperature field to laplacianFoam, and exactly following the guide:

http://openfoamwiki.net/index.php/Ho...ure_to_icoFoam

everything was ok until I typed in "wmake",
it was shown that:

merlin@ubuntu:~/OpenFOAM/merlin-1.7.1/applications/solvers/my_icoFoam$ wmake
Making dependency list for source file my_icoFoam.C

Additional informations are:
My operating system is Ubuntu, and I installed openfoam in /opt/openfoam171 as you see it.

The last thing is if it worked as how it is supposed to be, there would be an executable named as my_icoFoam under linuxGccDPTpt, right?

I would really appreciate your time to help me!

Hi Merlin,

you don't have write access to the OpenFOAM directory in /opt.

Change the Make/files entry for EXE from
EXE = $(FOAM_APPBIN)/my_icoFoam

to

EXE = $(FOAM_USER_APPBIN)/my_icoFoam

and see, if it works...
