Dear All,

I'm using OF2112 installed on WSL2 version of Ubuntu. I want to create a custom solver based on pimpleFoam, but I have a problem with compilation. To test it, I've copied pimpleFoam directory to my local dir ($WM_PROJECT_USER_DIR/applications/solvers/incompressible), changed everything relevant (names, Make/files), but I did not make any changes in the code. And when I'm trying to wmake the following errors appear:

In file included from testPimpleFoam.C:82:
CorrectPhi.H:2:1: error: expected constructor, destructor, or type conversion before ‘(’ token
    2 | (
      | ^

      | correctPhi

make: *** [/usr/lib/openfoam/openfoam2112/wmake/rules/General/transform:35: Make/linux64GccDPInt32Opt/testPimpleFoam.o] Error 1

I don't understand what's going on here.
From my investigation OF has a problem with similar names of two files: CorrectPhi.H (with capital "C", from $FOAM_SRC/finiteVolume/cfdTools/general/CorrectPhi/CorrectPhi.H) and correctPhi.H (lowercase "c", from pimpleFoam local dir). Both files are included in pimpleFoam (in my version CorrectPhi.H in line 82 and correctPhi.H in line 158).

I found two fixes of the issue:

• provide full path when including CorrectPhi.H (in my case "/usr/lib/openfoam/openfoam2112/src/finiteVolume/cfdTools/general/CorrectPhi/CorrectPhi.H" or "/usr/lib/openfoam/openfoam2112/src/finiteVolume/lnInclude/CorrectPhi.H", both are working);
• rename "correctPhi.H" inside pimpleFoam dir and change #include directive inside the PIMPLE algorithm.

After application of any of the fixes, the wmake finishes smoothly and solvers seems to work fine.

But I want to know the reason of this error. It looks strange for me.

I have the same issue with OpenFOAM v9 (Foundation) and by using docker on my MacBook. I use the same solution as you do and I still don't have an explanation... Hope someone will help to understand that

Late to the party but I came across this thread while running into the same issue (v2206, wsl2, ubuntu, win11)

In my case, I had copied the solver files to a working directory that was shared with Windows (somewhere in /mnt/) so Windows' lack of case-sensitivity in file naming was causing a conflict between correctPhi and CorrectPhi at some point either when copying the files or compiling.

Copying to and working from a directory on the wsl machine that wasn't shared with Windows fixed the issue for me.
