Compiling in x64 linux

Hello Everyone
I'm trying to get Grit to run in a x64 linux.
i got it to compile and link correctly but i experience segfautls at startup so I compiled the dependencies with debug simbols enabled.

This what the executable shows on console.

Code:

I dont know why this is happening. Flight gear and vdrift work ok, so i assume that the video drivers are working. (propietary ati drivers for a Radeon 6950)

Tomorrow i will try to fiddle a little with the code to see if i can fix it but i never used ogre so dont hold your breath.

Also if you need some other log or data just tell me.

Thanks for an excellent report. The problem is unfortunately very simple, Ogre does not properly support ATI on linux so we can't support it either. All our shaders are written in CG and the only ATI GL targets that CG supports are the arb assembly syntaxes (which are too limited) and glsl which Ogre does not allow. Here are some recent posts on the ogre forums where i mention the issue.

At some point in the future I may write my own shader stack and stop using Ogre's but that is a very long term dream.

Well, i didnt expect that.
Is it possible to disable the shaders? As far as i could understand they are mostly used for lighting and postprocessing.
Maybe i could hack a little around that to add some checks and if the platform is unsupported disable those and fallback to some other safer alternative?
But maybe i'm missing something and the whole shader stuff is fundamental to the rendering system and can't be solved that way.

There seems to be some support for GLSL in the manual [1] and in the source code starting from ogre 1.7

I could try to convert the shaders from cg to glsl, but somewere i read that those are converted at runtime, i cant find a link right now.

i'm Not a good programmer and my knowledge of ogre and the whole shader stuff is new to me, but if you think is possible i could try to make it run on my platform.

ps. Oh and Btw English is not my native language so if somewhere i dont make sense, just tell me and i will try harder.

That sounds really great DArkz, as far as I can remember, while ATi now AMD could stand to step up their support on Linux, I believe Spark has only left ATi/AMD in the back yard because he hasn't had a system with ATi/AMD hardware. I'll encourage you outright but wait for Spark on this, and you are welcome to the chat room for a more closer to real time experience if you'd like to take this on and contribute to the project.

There isn't "always" someone there, and Spark is really the only one who can probably give you insight anyhow, but he keeps himself available for the most part

Welcome to the community!

Thanks Brian.
I would like to contribute to the project as far as my skills permit.
Disabling the shaders got rid of the segfault, so the whole project runs ok on x64 linux.
Ofcourse without the sun i cant see nothing

so i will try to convert that to glsl and see if it works.
I will hop on the irc in a while.

The shaders are unfortunately rather fundamental. You can disable them, but it will look really awful and probably be glitchy. The only reason that option exists (I assume you are trying the debug_cfg.fixedFunction or something like that) is because the project used to use shaders less extensively. But now, they are used for pretty much everything so you will be quite stuck without them. Current versions of GL and DirectX have removed the fixed function pipeline and we will probably follow suit in time.

While Ogre does support writing glsl shaders directly, it does not support converting from cg to glsl at runtime. This is because it considers glsl to be a high level language, even though it is the target language of the cg compiler (another 'high level language' in ogre's design). You could manually rewrite the shaders in cg, but this would be a lot of work as there are thousands of lines of htem, and you'd have to change lots of other support code too. So don't do that, I don't want to maintain it

It would probably be easier to fix ogre anyway.

I suggest you use windows (and thus D3D9 if you cannot get a nvidia card.

The reason nvidia works is that nvidia define assembly languages that are more powerful than the standard arb assembly languages, so we can use them, and ogre considers them 'low level' so it will compile cg to them at runtime. ATI has no such equivalent - they only provide glsl and the arb assembly languages, and the latter are not powerful enough.

Spark, thanks for the insight.
It seems that i wont be able to use this engine as windows is not an option for me ( 24/7 linux user and fundamentalist ) and indeed converting the shaders is way over my skills, it was ok until i found SkyProgram.cg.

It looks like i will be better of writing my own engine as my needs are pretty simple.
I will come back after ogre or ati fix the issue.

Thanks again for your time and good luck with Grit, it looks awsome and the code quality is great!

Spark · **Joined:** Sat Mar 27, 2010 1:13 pm **Posts:** 420

Sure that probably makes sense.

Out of interest, what were you intending to use Grit for?

DArkz · **Joined:** Thu Jun 28, 2012 9:45 pm **Posts:** 5

The plan is having a big network of roads add a vehicle and some hooks to accept remote commands from a program like emulating the keyboard input.
With some black magic, export the rendered stream(the Opengl viewport) to a v4l device.
That device will be used by another program running opencv that will drive itself around the city using only the video as reference for obstable avoidance and a gps for current location, destination and pathfinding.

Something like an autopilot for a car but without any sensors apart from the video feed.

All of this is to avoid having to buy a ton of electrinics that, when the program works will be outdated, or not the best for the job.
So simulation on the inital steps is the way to go.

Very interesting, you wouldn't need any advanced graphics for that at all. Sky neither. You could just simply tear all of that out, although it's not been done for a while.
