To compile with 64bit labels set WM_LABEL_SIZE=64 in ~/OpenFOAM/dev/prefs.sh source ~/.bashrc then Allwmake in OpenFOAM-dev. This will build into for example OpenFOAM-dev/platforms/linux64ClangDPInt64Opt If WM_LABEL_SIZE is unset or set to 32: WM_LABEL_SIZE=32 the build would be placed into OpenFOAM-dev/platforms/linux64ClangDPInt32Opt Thus both 32bit and 64bit label builds can coexist without problem.
