I looked now (as the error message suggests) into the PackedList.H and by switching the base class (private List unsigned int ) from private to public (public List unsigned int ) the error seems to vanish.

I added the two constructors and had to add some others witht he same error. I got than an error regarding the typedef In file included from /opt/OpenFoam/foam-extend-5.0/src/foam/lnInclude/Pstream.H:43, from fileMonitor.C:28: /opt/OpenFoam/foam-extend-5.0/src/foam/lnInclude/labelList.H:46:31: error: conflicting declaration ‘typedef class Foam::UList<unsigned int> Foam::unallocLabelList’ 46 | typedef UList<unsigned int> unallocLabelList; | ^~~~~~~~~~~~~~~~ In file included from /opt/OpenFoam/foam-extend-5.0/src/foam/lnInclude/HashTable.C:30,...

Hi, thank you for you help! I now tried as you suggested and pulled the nextRelease branch and tried to compile. I still get the same errors, such as: SOURCE=motionDiffusivity/inverseDistance/inverseDistanceDiffusivity.C ; g++ -std=c++14 -m64 -Dlinux64 -DWM_ARCH_OPTION=64 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3 -DNoRepository -ftemplate-depth-200 -I/opt/OpenFoam/foam-extend-5.0/src/postProcessing/functionObjects/forces/lnInclude -I/opt/OpenFoam/foam-extend-5.0/src/meshTools/lnInclude...

Hi, I have the same problem. Would you please elaborate on how to approach this problem. Where do I switch the -std flag? Best regards, Christoph
