[Buildroot] final link failed: Nonrepresentable section on output during build ARM7TDMI uClibc toolchain with Buildroot

[Gary Altenberg <gary@ioengineering.com>]

Hi,

I have been attempting to build a toolchain for an ARM7 based board.

I chose the following settings in buildroot:

arm
arm7tdmi
EABI
Kernel headers for 2.6.21
uClibC 0.9.31.x
binutils 2.21
gcc 4.3.x

I want to use the toolchain to build uClinux for this board. I can build 
uClinux with some much older tools and older uClibc and it runs on the 
board but it's very buggy. Lots of memory problems. I thought if I could 
upgrade my tools, busybox and uClibc. I can't even build the latest 
busybox for this board with the old tools.

I am building buildroot on an Ubuntu 9.10 machine

I have attempted this with buildroot-2010.11 then with buildroot-2011.02-rc1

I extract buildroot then run menuconfig and just set the options for a 
toolchain with the parameters from above.

Each time I have run into the getline problem where 
linux-2.6.21/unifdef.c has a getline function that needs to be renamed. 
Renaming the function gets me past that.

Then I keep running into a problem with "final link failed: 
Nonrepresentable section on output" I have looked and looked but cannot 
find any solution to this.

Below is the end of the build of buildroot when it quits.

Should I use a different combination of tools, a newer set of kernel 
stuff, a newer build of Ubuntu? Any help would be appreciated.
