Jesse Jen,

Could you try ./configure --prefix=/home/jje/mpich-install –with-device=ch4:ofi?

I am currently downloading the latest version of mpich on a ubuntu machine. I am having trouble configuring (step 1d) as I do not understand the error messages. How do i proceed? The error message I receive at the bottom is:
This is the input:

root at master:/home/jje/mpich-3.4rc1# ./configure --prefix=/home/jje/mpich-install 2>&1 | tee c.txt



The error message I receive at the bottom is:



configure: error: no ch4 netmod selected


  The default ch4 device could not detect a preferred network

  library. Supported options are ofi (libfabric) and ucx:


    --with-device=ch4:ofi or --with-device=ch4:ucx


  Configure will use an embedded copy of libfabric or ucx if one is

  not found in the user environment. An installation can be specified

  by adding


    --with-libfabric=<path/to/install> or --with-ucx=<path/to/install>


  to the configuration.


  The previous MPICH default device (ch3) is also available and

  supported with option:


    --with-device=ch3

Here is a imgur link with everything in between:
