Question

每当我尝试在openfoam中编译求解器时，我都会收到错误：

我想问题是安装open-mpi。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是否已正确设置为使用Open MPI：请参阅etc/bashrc（或etc/cshrc）中的相应选项。还要确保为Open MPI设置了任何所需的环境变量（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wmake发布的链接命令行以构建解算器，和构建libPstream（在主OpenFOAM构建过程中）。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）应该包含一些链接选项，并且很可能是与Open MPI相关的路径。
