Dear Foamers,

I have a quick question about the directory complaint.
Currently, I am trying to compile my own solver based on 'interMixingFoam'. Some problems are raised in directory problem.During the compilation of my solver, the system complaints like ‘could not open file correctPhi.H for source file MLB.C due to No such file or directory‘. Hence, I reach the ../Make/options files, the shortcut path is written like:’$(LIB_SRC)’. However, my question is when I command ‘echo $LIB_SRC’ in the terminal, it seems like there is no such a path being able to be recognized.
I am not sure the reason for that. Can you please give me some comment about this error?

The directory seems like an easy-solving bug but cannot recognise it. Have read about all the former post about the directory problem but seems not work for my case. Really appreciate any help!

Thanks,
Linyan

Echo does not work, because it is not an environmental variable. Rather, it is a local variable to the wmake script.
When you call wmake, you execute a script, which eventually looks at your Make/files and Make/options file. Before doing so, it sources this file:

(...)/OpenFOAM-4.0/wmake/makefiles/general

which does:

LIB_SRC         = $(WM_PROJECT_DIR)/src

and there you have your (non-environmental) variable!

The file "correctPhi.H" is not part of OpenFoam's source tree. Rather, it is part of the interFoam solver.

So my guess is, when you based your solver on interMixingFoam, you only copied interMixingFoam, whereas you should have copied the parent directory (interFoam) as well.
That's why in Make/options you see "-I.. ".

Thanks! Kevin. You've made my day. Like what you comment, the reason for system's 'Could not find such a file or directory'complaint is partly copying the interMixingFoam solver instead of the whole interFoam package. As it complaints, the CorrectPhi.H is one of the header files for interFoam instead of the OpenFoam's source tree. Hence, the header file should be copied along with the to-be-modified solver.

Again, thanks for Kevin's help.
