Packaging failed for Linux

anonymous_user_bb2eb5ea · March 15, 2015, 6:37pm

On Ubuntu 14.04 I could not build my first project. I need more instructions and build settings for Qtcreator or Eclipse.
Later install on Windows 8.1 failed by saying to not recognize Linux compiler (or something alike)
Thanks for fixing

Hey Mike4-

Could you provide some additional information to hep me understand your issue. Are you trying to create a new project on Linux? Are you trying to compile a project for Linux on a window’s machine? Have you tried following the instructions on this wiki page: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

Let us know what it is that you’re trying to do and where the problem is happening.

Cheers

Attached two images from Win8.1. First I try to compile for win64 and second for Linux. Both fail and if I remember correctly I got the same output while compiling on Ubuntu as for win64, which is no wonder as I haven’t figured yet how to set up quickly either Qtcreator or Eclipse on Ubuntu 14.04.
So many thanks for help to compile all 3 variants of my project. Regards

PS: I first installed the binary to G:\ and later compiled the source on Win8.1 H:. Can I now delete/uninstall the binary? I ask because I haven’t seen a launcher in the compiled source.

Hey Mike4-

Are you referring to compiling the project code or trying to package the full project? Do you get the same error if you try packaging a new blank project?

Additionally, you can uninstall the binary version of the engine if you’d like to.

Hey
I’ve only used the 3rd person demo 2 days ago and added the water surface from the learn section in the launcher.
Hmm, I see there’s seems no source code to come with those demos as in the screenshot? Could I use
those in any way I want or are there restrictions? How to get the source to compile?

I will delete the downloaded gameengine binary folder as it doesn’t show up in win-installed programs. Only the launcher and ue4-prerequisites show up.

Thanks again

Are you working on Linux or on Windows? What are you attempting to do that gives you that error message? Do you receive the same error message if you attempt the same thing in an empty project with no additional content?

anonymous_user_bb2eb5ea · March 18, 2015, 6:31am

I dualboot Win8.1 and Ubuntu 14.04 64bit. So now I’ve tried the blank/basic demo (only some chairs and table) but it fails on Ubuntu, see screenshot.

So workflow is to build - cook - package? Anyway how to get & compile the source for my first project?

anonymous_user_bb2eb5ea · March 18, 2015, 7:17am

Ok I’ve managed to compile the basic example on win8.1 for linux with the binary engine that I’ve downloaded before compiling the source on both linux/windows.
So what do I miss while compiling the engine on Linux or Windows?

While we’re at it. Trying to run it on Ubuntu I get as below. I’ve steam
installed
Thanks

Do you think the Linux compile error is similar to mine posted here?

I have had to go back to Windows until I can work out why Unreal wont compile on my Linux Setup.

anonymous_user_bb2eb5ea · March 18, 2015, 9:25am

Yes, looks like. I get those errors on Windows or Linux using the compiled engine. Seems we miss a step after compiling the engine.

anonymous_user_2b03d27c · March 18, 2015, 2:08pm

Hey Mike4-

It appears that the problem you’re having is with packaging your project rather than building/compiling the editor. If this is not the case please respond and let us know exactly what you are trying to do and how it is failing. I have confirmed that there is an issue with packaging a project on Linux and have submitted a bug report (UE-12063) for further investigation.

Cheers

Yes building the editor/gameengine works but problems arise later by using this compiled engine. And this is the same on Windows.- Apparently there’s one step missing after building the engine like downloading the source folder or alike for any projects.

Then I would need to know how to compile projects on Linux and by using a windows compiled project, how to solve the link error I’ve mentioned.

Thanks

anonymous_user_bb2eb5ea · March 18, 2015, 4:09pm

the link error is solved by copying the lib in the same directory.
Shadermodel 4 is not supported on Linux, water looks simply flat like in the editor?

anonymous_user_bb2eb5ea · March 19, 2015, 6:44am

Yes there are files missing if you build the editor/engine from sources, whether on Linux or Windows.
What I did for solve is copy all the Engine (binary download) from Windows over Linux, select merge but not replace.
And voilà my project compiles and runs fine on Linux. Should be the same on Windows.
Now I wait for shadermodel 4 (5?) to get water waves also on Linux.
