使用hello.c文件测试没问题，运行算例出现无可执行文件
困扰许久，不知怎么解决，，（因为这个 我把系统都重搞了一编）zc7565@chun:~/MPI/openmpi-4.0.1/examples$ mpirun -np 2 hello_c Hello, world, I am 0 of 2, (Open MPI v4.0.1, package: Open MPI chun@RedPea Distribution, ident: 4.0.1, repo rev: v4.0.1, Mar 26, 2019, 106) Hello, world, I am 1 of 2, (Open MPI v4.0.1, package: Open MPI chun@RedPea Distribution, ident: 4.0.1, repo rev: v4.0.1, Mar 26, 2019, 106)Decomposing mesh region0 Create mesh Calculating distribution of cells Selecting decompositionMethod simple Finished decomposition in 0 s Calculating original mesh data Distributing cells to processors Distributing faces to processors Distributing points to processors Constructing processor meshes Processor 0 Number of cells = 1134 Number of faces shared with processor 1 = 47 Number of processor patches = 1 Number of processor faces = 47 Number of boundary faces = 2381 Processor 1 Number of cells = 1134 Number of faces shared with processor 0 = 47 Number of processor patches = 1 Number of processor faces = 47 Number of boundary faces = 2363 Number of processor faces = 47 Max number of cells = 1134 (0% above average 1134) Max number of processor patches = 1 (0% above average 1) Max number of faces between processors = 47 (0% above average 47) Time = 0 Processor 0: field transfer Processor 1: field transfer End zc7565@chun:~/OpenFOAM/zc7565-dev/run/DM$ mpirun –np 2 interFoam –parallel > log-------------------------------------------------------------------------- mpirun was unable to find the specified executable file, and therefore did not launch the job. This error was first reported for process rank 0; it may have occurred for other processes as well. NOTE: A common cause for this error is misspelling a mpirun command line parameter option (remember that mpirun interprets the first unrecognized command line token as the executable). Node: chun Executable: –np

mpirun 把 -np 当成程序名了，你的横线写错了，
–应该为-。

@wwzhao 谢谢拉 困扰了我这么久 还一直以为是 环境变量的问题呢
