Dear all,

I am having problems installing waves2Foam on my system (Ubuntu 20.04, running on Windows 10 via WSL). I have OpenFoam v2012. Following the waves2Foam manual, I first installed the required third-party dependencies (that is gfortran, git, SVN and GSL). However, I get this error when running the ./Allwmake command in /applications/utilities/waves2Foam, during the solver compilation step:

/usr/bin/ld: cannot find -lwaves2Foam
/usr/bin/ld: cannot find -lwaves2FoamGABC
/usr/bin/ld: cannot find -lwaves2FoamSampling
collect2: error: ld returned 1 exit status

I attach a partial log of the compilation since I think the errors are just for the PRE-PROCESSING and SOLVER compilation. A similar case was presented by bknorris (waves2Foam on an Ubuntu 18.04 with OpenFOAM 1712), but I tried what lppferreira suggests with no success.

Has anyone experienced something similar or knows a workaround? Thanks!

**Edit**
I've found the same issue here -Can't find libraries for waves2Foam installation-, but unfortunately the proposed solution did not work for me.

I have the feeling that the error may be originated already in the LIBRARY compilation, which occurs before PRE-PROCESSING and SOLVER. During the LIBRARY compilation, I get four different errors (see attached file for an example, full log was too long):
/usr/bin/ld: cannot find -lgfortran
/usr/bin/ld: cannot find -lwaves2Foam

Dear all,

After some days of investigation, I think I found a solution. The error comes from waves2Foam not finding the gfortran library (libgfortran.so). Turns out waves2Foam is not looking for it in the right directory, so going into waves2Foam/src/waves2Foam/Make/options.220 one should add the following at the end of the file (also do the same for the options.220 file located inside the waves2FoamGABC/Make folder):

LIB_INC = \
-I$(GFORTRAN_PATH) \

Where $GFORTRAN_PATH is the path to the folder containing the library libgfortran.so, in my case /usr/lib/gcc/x86_64-linux-gnu/9/. I had thus to run the following line:

export GFORTRAN_PATH = /usr/lib/gcc/x86_64-linux-gnu/9/

Personally, I found out about this solution at a later time so I did not try it. Thus, I cannot ensure this will work, but it should be equivalent to what I ended up doing. What I did instead was to create a link for the libgfortran.so file into the OpenFoam library folder, which waves2Foam automatically checks. In my case:

ln -s  /usr/lib/gcc/x86_64-linux-gnu/9/libgfortran.so /opt/OpenFOAM/OpenFOAM-v2012/platforms/linux64Gcc63DPInt32Opt/lib

After that, just go to the waves2Foam folder, run ./Allwmake and you’re done. This error does not seem to be caused by the WSL compatibility, since it also appears in another installation I tried on CentOS. Thus, I hypothesize it has more to do with the OpenFOAM version, in this case v2012.

Hope this can help someone

Thank you! It works and helps me a lot!
