问题描述
我正在尝试使用MPICH-3.3.2从源代码构建OpenFOAM，但是得到了
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

尽管我在export WM_MPLIB=SYstemMPI中设置了etc/bashrc。
但是有了OpenMPI，一切都会好起来的。
使用MPICH-3.3.2构建OpenFOAM还需要考虑哪些其他设置？
解决方法
在“openfoma/etc”目录下，有一个mpi的设置文件，你可以在里面修改你使用的mpich的版本和位置。希望这会帮助你。顺便说一下，bashrc文件不需要设置。
