Doh!

The clue was "error while loading shared libraries: libncurses.so.5".

I installed libncurses.so.5:

sudo apt-get install libncurses5:i386 libncurses5

..followed by apt-get update and apt-get upgrade

...gdb now runs, but gives me a whole new set of errors:

warning: Unable to find dynamic linker breakpoint function.

GDB will be unable to debug shared library initializersand track explicitly loaded dynamic code. warning: Could not load shared library symbols for 5 libraries, e.g. /usr/lib/arm-linux-gnueabihf/libstdc++.so.6. Use the "info sharedlibrary" command to see the complete listing. Do you need "set solib-search-path" or "set sysroot"? Cannot access memory at address 0x0

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-a..., 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?
