This got my build working on AC100:

Oggetto: [ARMedslack] Compiling mame fro ARM


Way back in 2006 I had a working xmame for my Z that even if a little slowly it worked.

Since then xmame has been dropped and original mame now builds on unix.
I've built mame0143 on my x86 linux pc but I've had no luck on ARM.

The old xmame sources build but produce a binary that complains about endianness while I was unable to compile normal mame on ARM.
I tryed fiddling with CFLAGS to force little endian but it did no better.
I've totally forgotten whatever I did way back in 2006. Anyone have any idea ?

Regards
David
