yambo: invalid option -- X

[nsingh3]

Hello developers,

I am trying to reproduce the BSE calculation of bulk h-BN as given on the webpage. I get the tarball for the same from the yambo wiki and start following the steps written in "Calculating optical spectra including excitonic effects: a step-by-step guide". I encounter the following error when I do static screening module.

[nsingh3@int2 YAMBO]$ yambo

yambo: invalid option -- X

This is yambo 4.5.3 rev.171 - MPI+OpenMP+HDF5_IO -
Usage: yambo -h -H -J <opt> -V <opt> -F -I <opt> -O <opt> -C <opt> -D -W <opt> -Q -E <opt> -M -N -i -o <opt> -k <opt> -y <opt> -r -x -d -b -p <opt> -g <opt> -l -a
Try `yambo -H' for more information

Any help in this matter will be helpful.

Dear Nisha,

the tutorial are meant for the yambo 5.x release.
the -X s option is for the 5.x release.
In previous releases static screening is activated by:
yambo -b

you can type:
yambo -h
for the list of options.

In any case I strongly suggest you to update to the newest release:

git clone git@github.com:yambo-code/yambo.git yambo

Best,
Daniele
