Dear users and developers

I'm attempting to run a toy dft calculation with the following input. I get the following error. I'm attaching the following input. I am using nwchem 7.2.2

start n2

geometry
si 0.00000000 0.00000000 0.00000000
h 0.75252170 -0.75252170 0.75252170
h -0.75252170 0.75252170 0.75252170
h 0.75252170 0.75252170 -0.75252170
h -0.75252170 -0.75252170 -0.75252170
end

basis spherical
 * library sto-3g
end

DFT
XC b3lyp
end

task dft
 
Here's the error. Any help would be appreciated.

This input file show not result in 13 linear dependencies (where 13 is number of basis functions!)
This is a clear sign that major issues in your NWChem installation.
Could you try to use the NWChem Docker images as described in https://nwchemgit.github.io/Containers.html#docker, instead?
