I am trying to build OpenFOAM from source with MPICH-3.3.2 but got

g++ -std=c++11 -m64 -Dlinux64 -DWM_ARCH_OPTION=64 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -Wextra -Wold-style-cast -Wnon-virtual-dtor -Wno-unused-parameter -Wno-invalid-offsetof -Wno-attributes -O3  -DNoRepository -ftemplate-depth-100  -I -IlnInclude -I. -I/home/pranto/OpenFOAM-dev/src/OpenFOAM/lnInclude -I/home/pranto/OpenFOAM-dev/src/OSspecific/POSIX/lnInclude   -fPIC -c PstreamGlobals.C -o /home/pranto/OpenFOAM-dev/platforms/linux64GccDPInt32OptSYSTEMMPI/src/Pstream/mpi/PstreamGlobals.o

Although I set

export WM_MPLIB=SYSTEMMPI

But with openmpi everything is ok.



What are the additional settings I have to consider to build OpenFOAM with MPICH-3.3.2?
