compiler-errors - 如何使用自定义MPI实现编译OpenFoam？

我正在尝试在CentOS 6.6中安装OpenFoam-19.06
我在/global/mpi/mympich中有一个MPI版本。
在文件etc/bashrc中，我创建了变量:

export WM_MPLIB=MYMPICH

>
在文件etc/config.sh/mpi中，我创建了一个新案例:

MYMPICH)
    export FOAM_MPI=mympich
    export MPI_ARCH_PATH=/global/mpi/mympich
    export MPICH_PATH=$MPI_ARCH_PATH

    _foamAddPath    $MPI_ARCH_PATH/bin
    _foamAddLib     $MPI_ARCH_PATH/lib
    ;;

然后用以下命令设置环境变量:



并使用(在适当的目录中)编译第三方软件:



最后，我使用OpenFoam编译(在适当的目录中):



似乎开始很好:

========================================
2019-11-15 13:24:03 +0100
Starting compile OpenFOAM-v1906 Allwmake
  Gcc system compiler
  linux64GccDPInt32Opt, with MYMPICH mympich
========================================

built wmake-bin (linux64Gcc)

========================================
Start ThirdParty Allwmake
========================================
using:  gcc -m64 -DOPENFOAM=1906 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -O3 -fPIC
using:  g++ -std=c++11 -m64 -DOPENFOAM=1906 -DWM_DP -DWM_LABEL_SIZE=32 -Wall -Wextra -Wold-style-cast -Wnon-virtual-dtor -Wno-unused-parameter -Wno-invalid-offsetof -Wno-attributes -Wno-unknown-pragmas -O3 -DNoRepository -ftemplate-depth-100 -fPIC

========================================
Build MPI libraries if required
    /global/mpi/mympich

但结果如下:

到目前为止，我还没有找到完成目标的好指南。

最佳答案

在OpenFOAM-1712和更高版本中，提供了您所需的配置。它称为USERMPI。如果指定此选项，它将查找相应的mplib规则，您也将负责创建该规则。

最好是在gitlab跟踪器上提出文档问题/查询。

如果您想查看一个非常详细的示例，请查看spack openfoam/package.py-那里是spack中的值填充的
