HPUX app migration to CentOS

[atrium]

Been tasked with the feasibility of migrating our HPUX apps to centOS. Some of the issues is libraries.
Cant find info on the following libraries for centOS:

# System libraries
-lcurses -lm -lc -ldld

Legacy app uses old disam file system.

lasm -lscrn -lfile -lmat -lwb -lutil -lcmath -lutil -lasm -ldisam -ldewisp

Anyone been through such a conversion?

Thanks for your time
