尝试用 C++ 编译代码时遇到问题。我安装了 Intel Parallel Studio XE Cluster Edition 2020，但是当我尝试编译时出现以下错误：“ mpiicpc: Command not found ”。
当我运行命令时，icpc -v我得到以下结果“ icc version 19.1.3.304 (gcc version 7.5.0 compatibility) ”所以我认为我的安装是正确的。
我不明白的是，当我只是mpiicpc在终端中输入时，它会给我一个选项列表，我可以在这个命令中包含这些选项，所以我不明白为什么我在编译过程中会出现这个错误。
预先感谢您的帮助。
这是我使用的makefile（它来自lammps，我所有在与我相同的机器上工作的同事都能够毫无问题地编译它，所以我认为问题不在makefile中，但谁知道）
