[HOW TO] Compile Attract-Mode on your Odroid XU3/XU4

[tipoto]

Tutorial - How to compile Attract-Mode on your Odroid XU3/XU4.

This tutorial works for Attract-Mode V2.2.0

Log into your Odroid as Root user (otherwise you need to add "sudo")
Also these steps have been used on a Debian Jessie based image (OGST)

Install git-core

Code: [Select]

apt-get install git-core

Create a build environment:

Code: [Select]

cd /home/odroid
mkdir develop

apt-get install cmake libx11-dev libx11-xcb-dev libflac-dev libogg-dev libvorbis-dev libopenal-dev libjpeg62-turbo-dev libfreetype6-dev libxcb-randr0-dev libxcb-image0-dev libxcb-util0-dev libxcb-ewmh-dev libxcb-keysyms1-dev libxcb-icccm4-dev libudev-dev libavutil-dev libavcodec-dev libavformat-dev libavfilter-dev libswscale-dev libavresample-dev libfontconfig1-dev
(Attract-Mode was originally using libjpeg8-dev, but on debian Jessie it's been replaced by libjpeg62-turbo-dev, so if you don't have a Debian Jessie based image, maybe you'll need to install libjpeg8-dev instead)

Download and build SFML:
If you have installed OGST image on your Odroid, you should be able to install SFML just with this:

Code: [Select]

apt-get install libsfml-odroid
If it works, then you can skip the next steps and go directly to "Build Attract-Mode"

Otherwise you need a few more steps:

Code: [Select]

cd develop
git clone https://github.com/SFML/SFML sfml

Before building SFML library, 4 files need some modifications:
   /home/odroid/develop/sfml/src/SFML/Window/EglContext.cpp
   /home/odroid/develop/sfml/src/SFML/Window/EglContext.hpp
   /home/odroid/develop/sfml/src/SFML/Window/GlContext.cpp
   /home/odroid/develop/sfml/src/SFML/Window/CMakeLists.txt

You can directly replace them with the ones included in the attached file called "sfml.zip"

Then, on the terminal:

Code: [Select]

mkdir sfml/build;cd sfml/build
cmake -DSFML_OPENGL_ES=1 ..
make install
ldconfig

Build Attract-Mode:

Code: [Select]

cd /home/odroid/develop
git clone --depth 1 https://github.com/mickelson/attract attract
cd attract

2 files need to be modified in order to compile properly:
   /home/odroid/develop/attract/Makefile
   /home/odroid/develop/attract/extlibs/gameswf/gameswf/gameswf_freetype.h

You can find the modified files in the attached file called "attract.zip"

After overwriting these 2 files, do:

Code: [Select]

make
make install

You're done!
Now, to run attract-mode, type attract in the console.

Hey there, thanks for the write up.  This would be a great thing to add to the wiki as well.

Also I've updated the Makefile so building for ODROID and other GLES-based systems should be easier in the future.  NO need to apply the patch on the last step ("Build Attract-Mode").  Instead you would run make with the USE_GLES=1 option:

Build Attract-Mode:

Code: [Select]

cd /home/odroid/develop
git clone --depth 1 https://github.com/mickelson/attract attract
cd attract
make USE_GLES=1
make install

should do the trick...

[tipoto]

I just compiled the new v2.0 on the XU4 and it works great, however I still had to use the patch, otherwise I got the same error message as before (it doesn't manage to create the texture or something like that)

When I have a moment I will update the wiki.

[danfozzy85]

this doesnt work for me throws this error at me:

any help??

[tipoto]

Yes the line numbers are not the same now (after a few updates), so the patch doesn't work anymore, but I can provide to you all the modified files you need during the installation. I'll post them here once I get home.

EDIT: Oh, I just noticed that it was you asking for the same thing on the Odroid forums

[danfozzy85]

Your a gentleman, I posted over there too as neither post had been posted on for a long while!

[tipoto]

I updated the first post, it should now work with the version 2.2.0.
Let me know if there is any issue.

[danfozzy85]

Just followed your instructions worked a treat but on launching its saying it's version 2.1.0?

there any guides with setting this up on xu4 with the cores and emulators made on the OGST image as im lost!, an chance you could share your config files for linking the emulators and cores?

[tipoto]

Just followed your instructions worked a treat but on launching its saying it's version 2.1.0?

Yes it says 2.1.0 but it's actually 2.2.0. You can double check that by going to the menu and see if you can select a specific layout for the display menu. If you can, it means you are on 2.2.0 since this feature wasn't available before.

there any guides with setting this up on xu4 with the cores and emulators made on the OGST image as im lost!, an chance you could share your config files for linking the emulators and cores?

I use OGST but everything is completely customized on my image, all my emulator.cfg files point at one bash script actually. When this script is launched, depending on the type of system (arcade, port, OpenBOR, Nintendo consoles, Sega consoles etc... ), it launches another specific script, this one reads my own settings files (one txt file by system), then it launches the right emulator with the right rom.
So my cfg files are useless for you.

But when I have a moment, I'll give you the core paths and emulator list for each system, with that you should be able to create your config files.

[danfozzy85]

That would be brilliant, hopefully I can build up to something like your setup

[tipoto]

So first of all, I think you should install what meveric calls the "bad" cores on your OGST, it's an extra set of cores available on his repository, they are supposed to be less efficient or to have problems, but I use some of them, especially for the arcade games.

To install them, if I remember correctly, you have to type:
apt-get install retroarch-cores-bad

Here are the paths to all the cores (good and bad):
\usr\local\share\retroarch\cores\good
\usr\local\share\retroarch\cores\bad

Now, here is the core list and the systems they emulate:

You won't find some of these cores in your image since they have been installed separately. Meveric gave them to me for testing purpose, I don't find them anymore on his repository, so I guess he removed them and wants to prepare a clean package with them... I guess they will be available soon. However, while these new cores were supposed to significantly increase the performances, I actually didn't notice any improvement at all! Which is very weird, but maybe it's because of my settings, I need to investigate a little more.

Man thank you!

Thanks for your patience with me, got some learning/tinkering/playing to do

I did see a post by him saying that he's got a new update inbound that looks very promising.

[tipoto]

No problem

Don't forget to also check the first post of the OGST thread on the Odroid forums, and the thread itself, you'll find complementary information, but I'm sure you've been doing it already .

I forgot to mention that I only listed the Libretro cores, but you will also need:
reicast   (standalone -> For Dreamcast)
ppsspp   (standalone -> For PSP)
mupend64   (Standalone -> For N64)

For ppsspp and mupend64, always go for the standalone version first and if there is a compatibility issue, then try the libretro core instead, but the performances won't be the same. For reicast, you don't really have the choice since there is no libretro version installed of the emulator, so the standalone one is the only way to go.

[danfozzy85]

how do you put the path to the executable?  For example, im playing around with getting snes9x to work.. What im putting for the path is.

executable           /usr/local/share/retroarch/cores/good/snes9x_next_libretro.so

but im not having luck. As for the layout, marquee, etc ive got that sorted and looking nice just need to find the path for the emulators and launch them!


Edit: just had a look at the rom browser add on for xbmc, copied it's execute command (snes-xbmc) and that works. Getting tearing thought, seems there's no way round it either

[tipoto]

I think it should look something like this:

Code: [Select]

executable          /path/to/retroarch
args                -L /usr/local/share/retoarch/cores/bad_or_good/<CORE> -c /path/to/config.cfg "[romfilename]"
rompath              /home/odroid/<SYSTEM>/<ROM>
romext               .ext
system               System_Name
info_source          thegamesdb.net
artwork    flyer           
artwork    marquee         <MARQUEE PATH>
artwork    snap            <SNAP PATH>
artwork    wheel           <WHEEL PATH>

I don't have my XU4 with me and I don't remember the path to retroarch, but you can probably figure it out by typing this in a terminal:

Code: [Select]

which retroarch

The tearing is an annoying issue on the XU4 because of the kernel/GPU drivers, it's also why I use different cores in order to have different options and pick the best core for each game (so I can get the best performances and less or no tearing)
