Answer 1

转到http://www.mpich.org/downloads/并单击XenialUbuntu 16.04。这会将您带到这里：https : //packages.ubuntu.com/xenial/mpich。然后点击amd64你就在这里：https : //packages.ubuntu.com/xenial/amd64/mp​​ich/download。它在哪里说：

如果您运行的是 Ubuntu，强烈建议您使用 aptitude 或 synaptic 之类的软件包管理器来下载和安装软件包，而不是通过本网站手动进行。

因此，不要手动安装，而是使用：

$ sudo apt install mpich

没有必要像你试图做的那样从源代码编译。
