I have an issue with ncview on cygwin. Can anyone help?

I have installed cygwin on windows 10 and followed the instructions on Ncview under Windows.

my output from ./configure and make install are as follows:

But when I try and run an nc file with ncview WW3_AT_metop_2018_6a_c01_p002.nc, I receive the following error message:

$ ncview WW3_AT_metop_2018_6a_c01_p002.nc

-bash: ncview: command not found

I discovered the proper execution command should be as follows, although it still gives and error message:

$ /home/bjd/bin/ncview.exe WW3_AT_metop_2018_6a_grid_p071.nc

Error: Can't open display:

Solved by installing ncview via cygwin update.

Cygwin updates when you install the various new files through the installation process - where it just adds those files to the cygwin already installed.

I needed to get gnuplot working, by exporting the following environmental variable, and adding it to ~/.bash_profile:

export DISPLAY=localhost:0.0 , from:
