Subject: [mpich-discuss] Problems to install MPICH 3.4.1 in Ubuntu 20.04.2 LTS 64bits.
Hi everyone.
I hope you are doing well.

My name is Jean Schuster and I'm from Brazil.

I'm facing some difficulties in installing Mpich 3.4.1 in my Ubuntu 20.04.2 LTS 64bits machine following the install guide. I'm getting stuck in the 6th step on the section 2.2, where it suppose to build the Mpich through the "make" command (make 2>&1 | tee m.txt) when it returns mi te following error:

  jean at Prandtl:/tmp/jean/mpich-3.4.1$ make 2>&1 | tee m.txt
  make: *** No targets specified and no makefile found.  Stop.

After running ./configure --prefix=/home/jean/mpich-install 2>&1 | tee c.txt I get this message in the very end:

  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

And no Makefile is created on the source folder. The installation folder /home/jean/mpich-install remains empty.

I'm a relatively new Ubuntu user, and despite the installation guide goes step-by-step, I could not go through this error.
Attached follows the c.txt and config files from the temporary folder.
I hope you can kindly help me to get it to work.

Thank you in advance.

Best regards,
Jean.
