screen on arm-x19 device (QNAP TS-110)

[Thomas Käfer]

Hi there, I hope someone can give me a hint how I can make screen work
on my qnap-ts110.
I downloaded the latest screen version from http://ftp.gnu.org/gnu/screen/
then:
tar -xvf screen-4.0.3.tar.gz
 ./configure
make
make install

in between i had some problems with missing an compiler but i managed
to overcome those. now i have an "running" screen command which can
tell me with screen -ls that no session is active but when i want to
start a session i get the error:

Cannot find terminfo entry for 'xterm'.

What can cause this, and how to overcome this error?

Thanks for your help,

Thomas
