can't run the released binary version under linux

[1453042287]

when i run the CityEnviron.sh in ubuntu18.04 i got this error:

Increasing per-process limit of core file size to infinity. Signal 11 caught. Malloc Size=131076 LargeMemoryPoolOffset=131092 CommonLinuxCrashHandler: Signal=11 Malloc Size=65535 LargeMemoryPoolOffset=196655 Engine crash handling finished; re-raising signal 11 for the default handler. Good bye. Segmentation fault (core dumped)

any suggestions would be appreciate! BTW, do i need to install the OpenGL?

The AirSim environment is tested to work on Ubuntu 16.04 LTS with Unreal 4.18. I gave 18.04 a try and couldn't get it to work, but 16.04 worked right away!

@tzimasak thanks, oh my god...

[1453042287]

@tzimasak em...i come back again, after change to 16.04, i download the CityEnviron.zip and extract it successfully, and i also add the path of .so in engine.zip to LD path, but when i run the CityEnviron.sh i still have the Segmentation fault (core dumped) error, is there something i missed?

I have the same problem with exactly the same error message (Ubuntu 16.04, Airsim 1.2.0 experimental binary). If anybody's found a solution I'd be grateful.

Hi, I face the same problem. The archive is probably corrupted. I can run the neighborhood version fine.

When I unzip the archive it complains about a data error inside the .pak file at around 60%. It also complain about missing header beginning of archive.

I tried unzipping with various 7zip versions (both linux and windows) but always got a data error, though some files are still extracted which produce the above error when run.

For reference these are probably the same issue : https://github.com/Microsoft/AirSim/issues/1548 https://github.com/Microsoft/AirSim/issues/1553 https://github.com/Microsoft/AirSim/issues/1528 https://github.com/Microsoft/AirSim/issues/1345 https://github.com/Microsoft/AirSim/issues/998

i have the same problem, i extract the zip file on the windows by 7zip, it told me some error occured in the head of file, but the file was total extracted. Then i test the CityEnviron on my unbuntu16.04, it always crashed and produce the same error like yours.

@sytelus hi, i saw you push the latest binary on the v1.2.0 Linux, have you updated the CityEnvironment package? i think something wrong with this achive

Hi, Have you solved the problem in the end? I got the same problem when testing the LandscapeMountains on my ubuntu16.04. I extracted the file with no error but could not get it to work.

[Baldins]

did you solve the problem?

[jnaor]

No...

We will check that our latest release of CityEnviron works on linux.

What is this engine.zip everyone is speaking of? I'm getting library errors running CityEnviron from 1.2. It complains about a missing libopenvr_api.so file. I see other environments with an Engine folder that has that library, but if I borrow their copy and add it to LD path, I get the signal 11 segfault that OP mentioned.

@ironclownfish Is the "latest release" of CityEnviron also going to take out the cars and pedestrians, like in the Windows 1.3.1 release?

Also using UE 4.24 on Ubuntu 18.04.

Update: CityEnviron binaries also segfault on 16.04

I compiled the version from source code and have the same problem, too. I cannot run ./UnrealVersionSelector-Linux-Shipping, with or without -opengl4 option. But I can run UE4Editor without crashing.

Are you talking about the City environment? Or the unreal engine itself? Code is not available for the former

Oh I mean the engine itself. Others may mean City environment. I just realized that there are no issues on Unreal Engine github repository.
