[Request] SteamOS support for Tourqe 2D

#1 SteamOS runs Linux.
Afaik T2D doesn't support Linux so I recommend you port it to Linux first, then do the specific port to SteamOS.
T2D shouldn't be far away from supporting Linux tho AFAIK. Try compiling it in a linux distro and see what issues arise.

#2 Since T2D is an OpenGL engine, a Linux port would probably be a bit easier than the work that is or was needed for T3D. Perhaps some smart person out there with a bit of free time could look at the platform code that Luis Anton Rebollo used for his T3D Linux port and figure out how to bring that to T2D.

#3 I posted about raising money to port T2D to linux for the upcoming steam OS but there wasnt much response at all.

#4 @Tim - I did not see that... I know that I would pay for something like that. :)

#5 Steam OS Just launched a few hours ago. Here you go.

#6 Built up a makefile to try and build torque2d. One of the biggest problems I see is that includes are not case sensitive. Box2D is referred to as 'Box2D/..', 'box2d/..', and other variations, which makes things frustrating. Do mac builds not suffer from the same problems or does it just depend on the filesystem there?

I haven't managed to test the existing platform code that is there (not sure what the state of it is, maybe from TGE days?)

#7 Eclipse complained about case sensitivity when I was setting up on mint linux to compile for android. I fixed it in my fork: https://github.com/practicing01/Torque2D/tree/development

#8 Well I spent a few hours cleaning stuff up for linux since I wasn't sure if there was already anyone doing so. Added makefiles for Torque2D and the libs, all objects are building now in gcc 4.8. Now to wade through the missing symbols and fix the various problems associated with openal. The x86UNIX code is as ugly as I remembered it to be :)

#9 @Frogger - I am not aware of anyone else actively working on Linux stuff for T2D so your efforts aren't going to waste and are appreciated. Once things are running without any major issues, we can talk about getting this in the development branch for community testing - similar to the Android port.

#10 Thanks. Got it to build fully, tracked down a few segfaults, starts up, but then dies in the texture manager. Looks like there's also problems with how relative paths on script execs are handled. Might be a while before things get stabilized :)

#11 Hm, so the TextureManager error is because canvas.cs wasn't being loaded, so a window wasn't being initialized, which caused gl calls like glGenTextures to not work since a context didn't exist :-/

But thankfully a (very unexciting) screenshot can exist now!

Also enjoy the slightly hilarious console output below! :P

so suffice it to say, I need to spend some more time figuring out why the path handling isn't correct.

#12 Hmm. So I'm not an expert, but there seems to be something wrong with the way that the path string is formatted in Con::expandPath.

Using the example above when doing
exec('./scripts/constants.cs');

Getting the full path to the script that is currently being executed works correctly (CodeBlock::getCurrentCodeBlockFullPath).

However, once we use dSprintf to combine:
pathBuffer = "/home/home/torque/Torque2D/modules/AppCore/1"
and
pSrc = "/scripts/constants.cs"
the result is incorrect, pathBuffer = "//scripts/constants.cs"

Replacing the call with sprintf ends up with the correct script path, "/home/home/torque/Torque2D/modules/AppCore/1/scripts/constants.cs"

Anyone have an idea why this might be happening? Replacing the call with snprintf also had the same trouble.

After replacing, things seem to be working very well!

#13 Good news for T2D users :D

#14 WHOOAA! This is just as exciting as the android port. Oh frabjous day, callooh callay!

#15 Hmm, so looking at the way Box2D was included, the folder is named 'box2d' rather than 'Box2D', which is what the library expects, as well as a number of includes in T2D.

What I did was change the folder to 'Box2D'. However, I'm unsure how that will affect other ways of building T2D, such as for android and mac. I suppose the project files/makefiles for those can be corrected with the proper case, but I don't have a way of testing that it will work in XCode after the changes are made again, and I was trying to keep the changes linux-specific.

It's interesting that Box2D isn't built separately from T2D proper and put in the libs folder like the other libraries that T2D uses (unless there's some T2D-specific changes that I'm not aware of?), but I guess it's not too important.

#16 yeah should just be a name change and should be committed to repo IMO.

#17 i dont know if its been fixed, but 64bit ubuntu had issues with torque because of sdl 1.3. The issue was compiling a 32bit binary on 64bit ubuntu. There was an ubuntu package bug preventing installing the 32bit SDL 1.3 libraries. Might also be a good idea to upgrade torque's SDL code to 2.0.

#18 Yeah, my desktop is a 64 bit install, so I use schroot as a nice build environment so that a 32 bit binary can be generated. Might be overkill since like you said it *should* be possible to do multiarch builds.

SDL 2.0 is certainly something that I'd like to get going. The unix platform code is quite a big mess at the moment, so we'll have to see how it goes.

The only bug that I've run into is adjusting the soldier count on the deathball toy, "Namespace:unlinkClass - reference count to parent is less than 0".

OpenAL seems to be initialized correctly, but I haven't tried checking to make sure that audio actually works yet.

Just as a quick test, the codebase seems to compile and run just fine using clang as well :D

#19 Do you have the latest development branch? I fixed that unlinkClass error (or at least i think that was the one i fixed)

#20 Yeah, latest dev commit here (from Oct 31), and I do see the unlinkClass commit as well.
