Hello FOAMers,

I am trying to use a stand-alone fortran code to calculate thermo properties of a fluid with given Pressure and Temperature values as input arguments. For this I need to compile the gfortran lib, but when I add the line "-lgfortran" to the Make/options file of my solver, I get (when running ./Allwmake to compile the solver) the following error message:

/home/faab/OpenFOAM/ThirdParty-2.3.0/platforms/linux64/gcc-4.8.1/lib/gcc/x86_64-unknown-linux-gnu/4.8.1/../../../../x86_64-unknown-linux-gnu/bin/ld: cannot find -lgfortran
collect2: error: ld returned 1 exit status
make: *** [/home/faab/OpenFOAM/faab-2.3.0/platforms/linux64Gcc48DPOpt/bin/hellChtMultiRegionFoamPorousAboveTLambda] Error 1

I have tried to look around for some info regarding this error but could not find anything relevant. Could you please help me solve this issue ?
Thanks a lot !

Have you tried to add the path to the gfortran library (i.e. to the directory containing the file libgfortran.so (probably with the version number in front of the .so)) with -Lpath/of/directory to the Make/options file?

Hi Joachim,

Thank you for your reply. That's what I actually tried to do first, but it did not work. I realized that it needed the libgfortran.a file to compile, so I did what you suggested but instead I linked the compiler to the folder in my /usr path containing the ".a" file. Now it works but the libgfortran.a file I linked is from the gcc-4.4.7 version, while I'm using the 4.8.1 with Openfoam, so I'm not sure I'm doing this correctly.

I renew this thread because still the issue has not been resolved, I was able to find a workaround only. The solver compiles correctly with no warning or error message when I add a link to the gfortran library (addind -L/... in the option Makefile), but when I run the solver on a testcase, at the end of the first iteration I get the following error message:
#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
