openfoam了openmpi错误：libmpi.so.0找不到

Question

每当我尝试编译openfoam求解器，我得到的错误：

我想这个问题是安装了openmpi的。我如何检查/修复错误？

Answer 1

首先，检查您是否确实安装了Open MPI。

其次，检查OpenFOAM是否被正确设置为使用Open MPI：请参阅etc/bashrc（或etc/cshrc）中的相应选项。还要确保你已经为Open MPI设置了所需的环境变量（我没有Open MPI的经验，我使用Intel MPI构建，并且有一些环境变量可以通过手动调用某些脚本来设置）。

第三，检查由wmake发出建立自己的求解器，和建立libPstream（在主OpenFOAM构建过程）的链接命令行。如果它不打印链接线，请编辑wmake/Makefile以使其打印出来。其中一些行（我认为libPstream）应该具有一些链接选项，并且很可能包含与Open MPI相关的路径。
