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.

Description
|
|
A label is an int32_t or int64_t as specified by the pre-processor macro
|
|
WM_LABEL_SIZE.
|
|
|
|
A readLabel function is defined so that label can be constructed from
|
|
Istream.
