Dear Sandeep,
checking for LIBOSMOCORE... no configure: error: Package requirements (libosmocore >= 1.9.0) were not met:
Package 'libosmocore', required by 'virtual:world', not found
I'm sorry to say, but if that message is not specific/helpful enough, then you do not appear to be a Linux software developer with sufficient background to build software packages from source code. Nothing about this is osmocom speficic.
In this case I'd strongly advise to simply use the pre-built binary packages we release, exactly for users who are users and not developers. See https://osmocom.org/projects/cellular-infrastructure/wiki/Binary_Packages
Thanks for your understanding, Harald
