Hi,

Has anyone tried to compile in Big Endian mode? When I compile the code in
big endian, I got the following message. Does anybody know how to solve this
problem? The assembler I'm using is "GNU assembler 2.11.90.0.27". I have no
problem compiling the code in little endian at all.

Thanks

Hanshi Li
