It is not enough. Ncurses has a lot of terminal files, they are probably in /etc/terminfo. The actual terminal type is stored always in the TERM environment variable, this is probably "linux" by you. The goal of this structure is to make the ncurses applications compatible, or at least usable anywhere. For example, a wyse terminal (ancient terminal from the antediluvian era) has absolutely different control sequences, as a linux or a freebsd console.
Only copying the library isn't enough, you need to copy /etc/terminfo/l/linux
as well.
Maybe further files can be needed, this can you test with a strace command (if you can't interpret its output, google is your friend or we are waiting your next question). The syntax:
strace -s 200 -f -o sux.txt ./theCommandToTest
It will dump the kernel call log of the ./theCommandToTest into the sux.txt text file.
Anyway, to test this thing, the best solution if you boot your linux in a command shell (f.e. use the init=/bin/bash boot option, or you call a simple bash from the local-top). So you will be able to run this strace, and play with this, to find out, what can be yet needed.
Good luck!
