I am using Hp pavilion 4 GB RAM i3 8th gen 4 core desktop. While installing Netcdf library or any libraries, the error is coming in "make install" step.

The error was captured in screen shot. The procedure followed is in PDF file. Please give me a solution.

Are you trying to install WRF or MPAS-Atmosphere? If WRF, I'll move this topic to the WRF support section of this forum.

In either case, the error in your screenshot appears to be due to an incorrect setting for the installation path of MPICH:
/bin/mkdir: cannot create directory '/mpich': Permission denied

In the instructions you attached, the configuration command for the MPICH library looks like:
./configure --prefix=$DIR/mpich

Have you correctly set the $DIR environment variable?
