Kindly help me out to solve this error

is KLayout installed?

Yes

This is a general linux problem. You need to find out what's wrong with regards to your system package manager. For example, this would be some basic troubleshooting with centos: https://unix.stackexchange.com/questions/523487/error-while-loading-shared-libraries-file-too-short

Then shall I directly run the precheck in efabless?

Yeah, you can

And also I am getting error in hold violation, how to solve it

Did you change the port names inside your top module to custom names? If so, do it like user_proj_example, where they have the counter inside a top module with the usual caravel port names. Otherwise you have to edit your timing constraints file with the respective port names

Where can I find the time constraints files ?
