Hi Mizan, The error message complains you can’t write to you designated installation path `/home/SOFTWARE`. Make sure you have the permission (by escalating to `root`) or set `prefix` to a location you have write permission. -- Hui Zhou From: Mizan Kamarudin via discuss <[email protected]> Date: Sunday, February 14, 2021 at 10:28 AM To: [email protected] <[email protected]> Cc: Mizan Kamarudin <[email protected]> Subject: Re: [mpich-discuss] Problem c.txt - MPICH installation [cid:[email protected]] [cid:[email protected]] [cid:[email protected]] Hello, I am currently having a problem in installation of MPICH.. after I put command "PATH=/home/SOFTWARE/mpich-install/bin:$PATH ; export PATH" it still says the error and I cannot proceed the installation..

At the bottom of the file it is said " configure: error : no ch4 netmod selected". This may be a self explanatory error but I'm a beginner on Ubuntu and my skills are limited yet. Could you help me with this problem ?
