Simulator problems

[Mmmm]

I just can't get the simulator to compile in linux...
I'm getting loads of undefined reference errors... this is how it starts:

Code: [Select]

LD rockboxui
/home/Martin/build/_rockbox/sim/libcomsim.a(io.o)(.text+0x7b9): In function `sim_codec_load_ram':
/home/Martin/build/_rockbox/uisimulator/common/io.c:354: undefined reference to `dlopen'
/home/Martin/build/_rockbox/sim/libcomsim.a(io.o)(.text+0x7e3):/home/Martin/build/_rockbox/uisimulator/common/io.c:362: undefined reference to `dlerror'

Then it goes on to lots more undefined references with X in the name:

Code: [Select]

/usr/lib/libSDL.a(SDL_x11events.o)(.text+0x969): In function `X11_KeyToUnicode':
: undefined reference to `XLookupString'
/usr/lib/libSDL.a(SDL_x11events.o)(.text+0xa2b): In function `X11_SetKeyboardState':
: undefined reference to `XQueryPointer'
/usr/lib/libSDL.a(SDL_x11events.o)(.text+0xc2e): In function `.L127':
: undefined reference to `XQueryKeymap'
/usr/lib/libSDL.a(SDL_x11events.o)(.text+0xc97): In function `X11_PumpEvents':
: undefined reference to `XNextEvent'
/usr/lib/libSDL.a(SDL_x11events.o)(.text+0xf20): In function `.L168':
: undefined reference to `XCheckTypedEvent'This goes on for pages and pages (full log file attached)

I've only just installed linux so I thought I'd probably not installed a certain package, but as far as I can tell I've got all the Xlib packages and SDL packages..

Anyone have any ideas?

What distribution are you using? It sounds like your LDOPTS are screwed up and you may have some packages missing from your Linux install (you shouldn't be getting unreferenced symbol errors from within the SDL libs). If you're using Fedora or some RPM-based distro, make sure you have all the relevent *-devel packages installed (sdl-devel, xorg-devel, glibc-headers, etc).

[Mmmm]

I'm using SUSE9.2 which is an RPM based distro...
I have:

sdl-devel 1.2.9-1
glibc-devel 2.3.3-118
but no xorg-devel...ooh..maybe that's it, I'll give that a go..Thanks
All I needed was a list of what should be installed...
 

[Mmmm]

 

oh well... it didn't work, I still get the same error
Now I also have:

xorg-x11-devel 6.8.1-15.4

Is there anything else that I should make sure I have?

[bk]

You are getting undef ref errors in your SDL installation which makes me think that whatever SDL packages you installed weren't compiled for your distribution, or you have some other dependency problem. In any event, I suspect your SDL packages are the root of the problem.

EDIT: Problem #1 is that you have different versions of sdl and sdl-devel installed. Problem #2 is that (according to google), the sdl that shipped with SUSE 9.2 was buggy wrt ALSA and possibly other things as well. Uninstall your SDL packages, reinstall SDL and make sure it is at least 1.2.8. Also make sure you update any dependencies.

[Mmmm]

WOOOOOOOOOOOOOOHOOOOOOOOOOOOOOOOOOO

Bk, you are my hero!!!

I could only find SDL 1.2.7-41.1 but that works fine, it compiles very nicely now....

Ok, now for the next problem..

below is a screen shot of the simulator...hmmmm seems the bmp file is not loading.. what do you think?

Yeah, the player bmps don't load for me either. I assumed that was intentional since the old X11 sim didn't have the pretty bmps either.

Glad to hear you got it working.

[Llorean]

Yeah, at the moment I think you have to actually use a command line parameter to get the background image, or something. I don't know what it is, but I know that by default it intentionally doesn't display it. I'm not 100% sure you can, but I think you can.

[Bagder]

./rockboxui --background

[nicolinux]

Ah, I see you have fixed your problems ! I still have mine but I hope I'll be able to resolve it !

[Mmmm]

Yep....

./rockboxui --background did the trick as you can see below!

How come this doesn't load by default? I suppose it's not really important eh?

How come this doesn't load by default?

Since it is just eye candy fluff with no useful purpose.

[Llorean]

I have to ask, is there a text or text-like file somewhere other than the source that tells the button->key mappings for any given simulator, or is it just the backgrounds and the source?

I'll admit I haven't looked around too much for this yet since I just thought of it, but since you mentioned that the image is "eye candy fluff" but it's also a quick easy way to reference the controls. Is there another way?

[Bagder]

I have to ask, is there a text or text-like file somewhere other than the source that tells the button->key mappings for any given simulator, or is it just the backgrounds and the source?

I don't think we have a document for it (yet). Most the sims do output a brief key mapping explanation on stdout when you start it though.

[Llorean]

Which would be fine, except I think the SDL sim doesn't show stdout in the console on cygwin at least. Well, no worries either way, I've gotten the hang of the sims I use.
