Got my N900 this week and tried out the armel build of sdlmame. The program begins to load and the console screen pops up briefly but then it crashes. Here's a the last bit of -verbose etting SDL_VIDEO_GL_DRIVER = '' ...
Build version: 0.135u3 (Dec 26 2009)
Build architecure: SDLMAME_ARCH=
Build defines 1: SDLMAME_UNIX=1 SDLMAME_X11=1 SDLMAME_LINUX=1 SDLMAME_NOASM=1

SDL/OpenGL defines: SDL_COMPILEDVERSION=1212 USE_OPENGL=0
Compiler defines A: __GNUC__=4 __GNUC_MINOR__=2 __GNUC_PATCHLEVEL__=1 __VERSION__="4.2.1"
Compiler defines B: __unix__=1
Compiler defines C: __USE_FORTIFY_LEVEL=0

Which game did you try to run?
Given the "Illegal instruction", I recommend to compile with "OPTIMIZE=0 DEBUG=1" to get you started.

What, no GDB backtrace?

That was the startup of the front end with no ROM specified, and compiled with OPTIMIZE=0. I'm guessing the console front end is a custom ROM (hence the bad instruction) and that suggests a pretty fundamental corruption of emulation. Perhaps its due to the endless warning on type casts from the earlier post. And yes, i guess it's time to break out the debugger.
The same build parameters work fine in the scratchbox (x86) target.

I'm guessing the console front end is a custom ROM Err... what? Ie what goes on when mame is run without specifying a ROM. For it to get an illegal instruction without even beginning an emulation there most be something exceptional about that code (pun intended). Anyway, building with DEBUG=1 fails. Compiling src/osd/sdl/sdlos_unix.c...
src/osd/sdl/sdlos_unix.c: In function 'osd_break_into_debugger':
src/osd/sdl/sdlos_unix.c:117: warning: implicit declaration of function 'kill'
src/osd/sdl/sdlos_unix.c:117: error: 'SIGTRAP' undeclared (first use in this function)
src/osd/sdl/sdlos_unix.c:117: error: (Each undeclared identifier is reported only once
src/osd/sdl/sdlos_unix.c:117: error: for each function it appears in.)
make[1]: *** [obj/sdl/mamed/osd/sdl/sdlos_unix.o] Error 1 The debug will have to wait until i have time to see what's going on.

For it to get an illegal instruction without even beginning an emulation there most be something exceptional about that code (pun intended). when you launch MAME without specifying game there is no custom ROM involved: it simply starts loading the empty driver from src/emu/drivers/empty.c (for your information, MAME could well support romless games with no problems, and indeed there are romless systems in MESS  ).

That's been mentioned before. Put a "include <signal.h>" in sdlos_unix.c. Without a stack trace honestly there is not much hope for support on a target which most (all?) devs do not have access to.

Well I got a N900 for Chrismas, so I will probably give SDLMAME a try... once I have installed the SDK on my Fedora 11 64-bit that is.

I've heard the N900 SDK is sufficiently Ubuntu-centric that on Fedora you're better off installing an Ubuntu VM image and running the SDK in that. Good luck
