RE: [arm-gnu]linker error section .got

Add "--fno-use-cxa-atexit " in you compile command line can fix this
issue.

Hi
I see, I got it wrong. Now I downloaded and installed the arm-none-eabi

toolchain (file:arm-2008q3-66-arm-none-eabi.bin) and installed it. Here

are the results:

-running configtool for eCOS (configuration for an AT91SAM7X256-based  
board):
starting it up, clear, then editing the prefix and removing the -m
option  
(arm4v is default) and building the eCOS. All ok

-Building my application that uses the above built eCOS library:
Compilation ok, but the linker finds hitherto unseen errors:

It seems I am still on the wrong track with this toolchain - or did  
anybody succeed in building an eCOS-based app using these tools?
Thanks for help and regards - Robert
