我是一个新的 linux 用户。我在编译期间收到此错误。当我在构建目录中使用“make”命令时。
Fatal Error: mpi.h No such file or directory
我已经使用这个安装了 OpenMpi：
sudo apt install libopenmpi-dev
我找到了 mpi.h 所在的文件夹：并尝试将其添加到路径中：
export PATH=$PATH:/usr/lib/x86_64-linux-gnu/openmpi/include
当我尝试 'make' 时，我仍然遇到同样的错误。我究竟做错了什么？谢谢。
编辑：我想我正在使用 G++ 编译器，这是完整的错误消息：
