Flandry Member Registered: 01/12/09 Posts: 24	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 Quote: 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 Build defines 1: LSB_FIRST=1 NDEBUG=1 DISTRO=generic SYNC_IMPLEMENTATION=tc 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 SDL Device Driver : x11 SDL Monitor Dimensions: 800 x 480 Using SDL single-window soft driver (SDL 1.2) Keyboard: Start initialization Input: Adding Kbd #1: System keyboard Keyboard: Registered System keyboard Keyboard: End initialization Mouse: Start initialization Input: Adding Mouse #1: System mouse Mouse: Registered System mouse Mouse: End initialization Joystick: Start initialization Joystick: End initialization Audio initialized - driver: pulse, frequency: 48000, channels: 2, samples: 512 sdl_create_buffers: creating stream buffer of 57344 bytes ouput: unable to open output notifier file /tmp/sdlmame_out Illegal instruction

Flandry Member Registered: 01/12/09 Posts: 24	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.

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. Code: 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 ).

couriersud Senior Member Registered: 19/02/07 Posts: 394	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.

ldesnogu Member Registered: 23/07/06 Posts: 89	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.

R. Belmont Senior Member Registered: 17/03/01 Posts: 12492 Loc: USA	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
