[OpenFOAM.org] Compiler Directives

Shabirmean · November 25, 2014, 13:51

Hi,

Where do I include compiler directives to be used when compiling an OpenFOAM case using wmake???

Ex: I want to use optimization flag -03 and -msse4.2

Can somebody please help??

Hi,

not quite get the meaning of "compiling OpenFOAM case" but if you'd like to modify optimization flags for OpenFOAM:

Code:

$ cd $WM_PROJECT_DIR/wmake/rules/<platform>

where <platfrom> is the name of the platform you're compiling for (ex. darwinIntel64Clang for OS X and Clang, linux64Gcc for linux and Gcc). There are c++Opt and cOpt files, where you can set your flags.
