No Variables in Variables View

I'm running a "makefile" project that I imported into LPCXpresso. I do not have the --gc-sections options set anywhere that I can see. I would like to get display of the local variables when I enter a function and hit a breakpoint.

Further, I haven't found any discussion of which options to set on the command line for gcc or ln when I'm building code for debugging using LPCXpresso and Red Probe.

Currently I have -g -O0 set on the compile line. My link command is creating a ".elf" file.

Could someone please help me with this?

Eclipse is a configuration nightmare.

Yup, I really like Visual Studio in this case. I have been developing a kernel mode device driver for the past few weeks and every time my system BSODs on me Visual Studio reconfigures in what seems to be a random layout :eek: I'll Just BSOD until I've got my preferred layout back and hope the driver works by then

The LPCXpresso tools provide a complete output of all the build commands (like make does) in the console window, so if you let LPCXpresso automagically configure your project(s) you'll get something like given below.
This might give you some hints on where to look.

Having --gc-sections or not should not make a difference - I've used both in my projects without any influence on showing local vars during debug.

OK, problem solved. Variables display now, but don't know what I changed. Eclipse is a configuration nightmare.
