When I am compiling the u-boot 1.1.1 for Versatile PB, a strange problem encounters.

Here the native (host) gcc is needed and used.
strip bmp_logo ./bmp_logo logos/denx.bmp
/home/roc/bootloader/u-boot-1.1.1/include/bmp_logo.h
/bin/sh: line 1: ./bmp_logo: cannot execute binary file
But obviously your native gcc does not create native code. I can only speculate and guess that your PATH must be set wrong, so that a cross gcc is picked up instead.
So I want to know which version of gcc is best for compiling the u-boot?
This has nothing to do with GCC versions, but with the local stup of the PATH on your system. "gcc" should never pick up a cross compiler.
