Xcode 4 for developing an embedded Linux kernel?

I am trying to use Xcode 4 (with external firmware) for embedded Linux to develop the ARM kernel. Please note that I have all the cross-compilers and tools that work from the command line on a Mac, but would like to use Xcode for convenience.

The standard make phase (make ARCH = arm CROSS_COMPILE = arm-none-eabiuImage) works fine, but cannot figure out how:

(a) Create a target that requires interactive input in the shell (do ARCH = arm menuconfig). This always complains about “Terminal opening error: unknown”, and with Xcode 4 in the background. Any ideas how I can open an interactive shell in the foreground?

(b) Use arm-none-eabi-gdb as my debugger. This is optional, but will be very neat.

Thank!

a) Can you figure out how to start the equivalent of xterm containing the command? Or some IDEs have a flag to run a command in an interactive window. Finally, let's look at how to make any menuconfig-related commands from the command line

b) Depends on whether xcode can use the gdb protocol as a whole. If possible, it is a matter of figuring out the whole procedure for starting the target gdbserver server. If this is not possible, you will need to debug text mode or use a gdb-compatible interface.
