SDL & Linux ARM

Discuss SDL programming with the RebelSDL plugin here

SDL & Linux ARM

Postby Allanon » Tue Jan 16, 2018 10:43 am

Hello,
I'm having problems trying to run a compiled application for Linux-ARM (odroid device to be more specific) that uses the rebelsdl.hwp plugin.
I've previously compiled other apps for this machine with Hollywood 6 without any problem, this is the first attempt to compile for Linux-ARM & RebelSDL using Hollywood 7.

The problem is that when I try to execute my program I'm getting always an alert saying "This program requires rebelsdl.hwp!".
But the plugin in the same folder where the executable is.
I've double-checked the plugin to be sure that it is right, and it is.
I've tried to run it from the icon and from the shell but with the same error.

My directory structure is:
Code: Select all
--+ program folder
  |
  +-- program_executable
  +-- rebelsdl.hwp
  +-+ data
    |
    +-- application data files...


I'm not familiar with Linux, but reading on the net I've tried to produce a log generated by the command "strace", if someone is skilled enough to understand what's the problem I'll be happy to send to him, I'm not posting it here because I'm not sure if it can have sensitive informations.

Have you tried to compiled for Linux-ARM + RebelSDL with Hollywood 7?

I think SDL on Linux needs some third-party software that you need to install first. If this third-party software can't be loaded, Hollywood can't load RebelSDL. To see the RebelSDL dependencies, run the following from bash:

Code: Select all
$ readelf -s rebelsdl.hwp


This will print a list of all shared objects required by rebelsdl.hwp. Please scan the list and see if you have everything listed, otherwise install the missing packages and try again.

Another thing may be that the ODroid XU4 (the model I have) has drivers for OpenGL ES but not OpenGL. If RebelSDL requires OpenGL, you may need to recompile SDL2 with OpenGL ES support or use GLShim to add OpenGL 1.x equivalence.

I've seen many UND under the Ndx column I suppose means UNDEFINED, since they all seems related to libc I've alse got the libc version installed:
Code: Select all
ldd (Debian GLIBC 2.19-18+deb8u10) 2.19

If the problem is related to libc I don't know how to update it because I've checked the available versions using apt and I've found that the latest available version is the 2.19 as showed above.

And to conclude here is the system version:
Code: Select all
Distributor ID:   Debian
Description:   Debian GNU/Linux 8.10 (jessie)
Release:   8.10
Codename:   jessie

Ok, seems like I made a mistake here. RebelSDL depends on libbcm_host.so which contains Raspi Videocore APIs and which is obviously not there on the ODroid. I need to build a new version of RebelSDL which doesn't have that dependency.

Alright, I've now removed the dependency on libbcm_host.so. Since I don't have an ODroid, can you test the new version and report if it works now? Here is the link: http://www.hollywood-mal.com/download/tmp/rebelsdl.zip

Hi, I had a quick test today.

There is no error with this new RebelSDL build but there are several problems, the first one is that running the program as is the performances are very poor... (seems like 1 or 2 fps).
As suggested by SamuraiCrow I've tried to run it using GLShim, in this case the speed is acceptable even if it still runs slow for an SDL app with not too much stuff on screen... Anyway, using GLShim there are many artifacts and graphical glitches that increase while using my test program.

I don't know at this point if it's a problem related to RebelSDL, to GLShim or anything else since I'm not familiar with the Linux world... any suggestions?

Have anyone tried to build an SDL app for the Raspi or the ODroid?

It's possible to use OpenGL ES under SDL 2.x since it supports Android also, but getting SDL2 to compile for Linux using the ODroid's drivers is tricky. I think there's a link on the ODroid forums but I will have to look later. If you can, try making your test app run on Hollywood Player so I can try running it under Android 7.1.1 via Lineage OS on my XU4.

Update:
I did some research on the ODroid forums and the proper solution is to recompile SDL2 without OpenGL support so the software framebuffer driver won't be found. Then it will find OpenGL ES2 correctly and use the ODroid's Mali graphics acceleration drivers.

Thanks for the research. Here's a new binary now which doesn't support OpenGL but only OpenGLES. Please try this on the ODroid and report back: http://www.hollywood-mal.com/download/tmp/rebelsdl2.zip
