uclibc supports cross-compiling ncurses?

[Juan Lablanca]

Taking into acount Steven's advice, I downloaded and compiled
sucessfully buildroot (as explained on
http://buildroot.uclibc.org/buildroot.html) with the following
configuration:

-Packet: ncurses
-Target Architecture: arm
-Target Processor type: generic arm
-Target Processor Endianess: Little Endian
-MMU: no
and i set "no" the rest of the options.

by the way, I had to fix a bug for this configuration, rebuilding busybox.

I got the files under /package/ncurses, ncurses.mk and Config.in from
http://www.uclibc.org/cgi-bin/cvsweb/trunk/buildroot/package/ncurses/.
Then i tried to compile my ncurses-program with this new created
compiler (arm-linux-gcc), but it failed by linking since all the ncurses
functions can not be found.

The makefile that i used to compile the ncurses program is as follows:

A part of the compiling output is:

Right now what i am wondering is whether arm-linux-elf supports ncurses.
Could you guys please give me a hand to solve that?

Best regards,
