How can I install `mpich` library? [closed]

How can I install mpich library? I tried compiling WRF but I could not install it.

Solution 1:

Go to http://www.mpich.org/downloads/ and click on Xenial for Ubuntu 16.04. This takes you here: https://packages.ubuntu.com/xenial/mpich. Then click on amd64 and you are here: https://packages.ubuntu.com/xenial/amd64/mpich/download. Where it says:

If you are running Ubuntu, it is strongly suggested to use a package manager like aptitude or synaptic to download and install packages, instead of doing so manually via this website.

So instead of installing manually, use:

$ sudo apt install mpich
