I am trying to set up an Eclipse/CDT development environment on an Ubuntu 14.04 (64 bit) PC to cross-compile and debug software for a RK3188 Arm platform.

To this end, I downloaded https://releases.linaro.org/12.10/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.7-2012.10-20121022_linux.tar.bz2, expanded and rearranged the distribution to simplify the path to the tools to /home/bob/Development/platforms/arm-linux-gnueabihf/bin.

With this arrangement I was able to compile a HelloWorld program without any difficulty and the executable ran on the RK3188 Arm platform and performed as intended.

I also copied gdbserver (/home/bob/Development/platforms/arm-linux-gnueabihf/arm-linux-gnueabihf/debug-root/usr/bin/gdbserver) to the RK3188 Arm platform and it could then be started remotely through Eclipse. At least, gdbserver was assigned a pid and output "Listening on port 2345". So far so good.

However, Eclipse was unable to launch arm-linux-gnueabihf-gdb; outputting an error, instead:
"Could not determine GDB version using command: /home/bob/Development/platforms/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb --version
/home/bob/Development/platforms/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory"
I tried running arm-linux-gnueabihf-gdb from the UpuntuPC's command line and got a similar error:
bob@myUbuntuPC:~$ sudo Development/platforms/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb --version
Development/platforms/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

Can anyone point me in the right direction?
