/ bin / sh：在Eclipse中找不到用于并行应用程序开发人员的mpic ++命令

Question

I'm trying to use Eclipse for Parallel Application Developers to do some MPI stuff but I can't get the program to compile. Below is the error I'm getting in the console:

Description Resource    Path        Location        Type
/bin/sh: mpic++: command not found  prog            C/C++ Problem

I use mpic++ from the command line (bash shell) to successfully compile programs. When I run the command using bourne shell I get an error.

/bin/sh mpic++
/usr/local/bin/mpic++: /usr/local/bin/mpic++: cannot execute binary file

When I use sudo I still get the same error. But when I first change to the bourne shell then run the mpic++ command it works.

/bin/sh
sh-3.2$ mpic++
clang: error: no input files

I've been looking at ways to change the shell used by eclipse so I can use the bash shell because I can call mpic++ without any problems. I've also tried launching eclipse with sudo but that didn't work.

Answer 1

I have compiled mpi in eclipse successfully. Please follow the steps:

1. In terminal type:

$ which mpicxx

/usr/local/bin/mpicxx

You should get the mpicxx binary path as result. I have my mpicxx in /usr/local/bin/ directory.

2. In eclipse, go to project properties:

   • Set GCC C Compiler as: /usr/local/bin/mpicxx
   • Also set GCC C+ Compiler as: /usr/local/bin/mpicxx
   • Set MacOS X C++ Linker as: /usr/local/bin/mpicxx . Also set All options as -L/usr/local/lib
