Unreal Engine 4.1 Released With Linux/SteamOS Support

What the heck do they use so that Win-to-Lin cross-compiling works, but native does not.

I have to admit that I find much of what I read in the world to be completely baffling.

It seems that there are so many software companies out there that are just dominated by drooling idiots or something. Maybe that comes across too harshly, but we're talking about -- in the grand scheme of things -- relatively simple concepts where big-name companies consistently show extreme incompetence.

Wait what?!

which part of "they started working on" and "you currently need" is hard to understand? the "native building on linux" is not made by epic i think. the fact that subscription makes source available is the fact that people with subscription can work on this. if you read a bit, you can see this started when source was released,

Building natively on Linux is not yet supported by Epic but some people on the forums and on GitHub have been trying to make it work based on the source code published on GitHub.

We've been discussing it on the forums and also on IRC at irc://irc.freenode.net/UE4Linux. If you'd like see working native Linux please jump in an join us.

that pretty much tells this is community project

You also currently need to copy the shared libary into you output folder so that the binaries can be run from there:

cp ./Engine/Source/ThirdParty/Steamworks/Steamv128/sdk/redistributable_bin/linux64/libsteam_api.so Engine/Binaries/Linux

Wait what?!

Why can't they make UT3 available to Linux then...

Yeah, this is a problem, I might have to dual boot, one with open source for general useage, and one with Catalyst for AAA games. I doubt the open source drivers will be able to cope with UE4 until we start seeing compliance with higher versions of OpenGL.

i would look that as positive, not negative. according to mesa, newer gl is not that far out

from gl4+ all new extensions are more or less optimizations that enable same thing perform much faster since you can avoid most cpu/gpu wait/sync states and drastically remove cpu bottlenecking.

and as much as it sucks if there is no support for it on your card, game or engine developed against gl4+ only could simply bring too much to the table to be brought down by legacy. gl4 is not something really new that would require $1000 card.

not to mention, dropping 3 and going with 4 would probably boost mesa progress

I wonder how hard it would be to port an UE3 game to UE4?

Pretty hard. A major component of UE3 was UnrealScript. UE4 now uses C++ for everything, so all the UnrealScript bits would have to be rewritten.

Epic!

[_SXX_]

Bonus points for when we get it running on r600g/radeonsi/etc.

As far as I understand for now UE4 only have OpenGL 3.3 renderer finished so it's should work on open source drivers just fine.
