geekdoc,

Yes, I used the makefile that you posted on your server to compile the 0.103 (slow) xmame. It gave me the same error message.

Here are the different ways that I have tried to compile (without success):

Tried compiling with -mcpu=arm926ej-s
Tried switching -Os to -O2
Tried compiling without -O2
Tried compiling with -fno-strict-aliasing instead of -fstrict-aliasing
Tried compiling with -O2 -mbig-endian -Wall ( fails on compile)
Tried compiling with -mlittle-endian

When I run the Unix file command on the files, I get:
xmame.SDL: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Lunix 2.4.17, dynamically linked (uses shared libs), not stripped

That looks to be correct since it is an LSB executable. I get the same message when I run file on other executables that work properly on the 770.

Do you still have the Makefile that you used for fastMAME?
