[Libre-soc-dev] Libresoc Environment Installation Error

[Santhosh Kumar V V .]

Hi, I am Santhosh Kumar V V from SASTRA University, doing project work
under mentorship of Manikandan nagarajan from SASTRA University.

I am currently working on replicating the libresoc environment and then
bringing the design to cadence.

I am getting the following errors during the ieee754 and nmutil
installation process.
