Linux Build of Game Does Not Find Mono...

    I built the example 2D platformer game from the asset store. I selected the Linux 64 bit option. I found that when I try to run it in Ubuntu 12 Linux, it says it cannot find Mono. I have tried installing Mono (package mono-complete), but it still cannot find it.

    This is the output:
    Code (csharp):
    1.  
    2. datahead@datahead-G750JW:~/Documents/TestBuilds/TestBuilds$ ls
    3. UnityPlatformer_Data  UnityPlatformer.x86_64
    4.  
    5. datahead@datahead-G750JW:~/Documents/TestBuilds/TestBuilds$ ./UnityPlatformer.x86_64
    6. Set current directory to /home/datahead/Documents/TestBuilds/TestBuilds
    7. Found path: /home/datahead/Documents/TestBuilds/TestBuilds/UnityPlatformer.x86_64
    8. Unable to load mono library from /home/datahead/Documents/TestBuilds/TestBuilds/UnityPlatformer_Data/Mono (x86_64)
    9. Failed to load mono
    10.

    This is an issue with running a built game in Linux, not in using the MonoDevelop code editor in Linux. I don't think those steps will work for this.

    Does anyone else know how to get a Linux build of a Unity game to find Mono?

    The 'Mono' folder (inside UnityPlatformer_Data) should contain two folders: etc and x86_64. x86_64 contains the file you've mentioned. Do you have the etc folder?

    Sorry for the very slow response. I had some things going on for a while.

    No, libmono.so is not present in the Mono/x86_64 directory. What might be preventing Unity from including this automatically if it is needed?

    Yes, I have a Mono/etc folder. For this built game, though, it is empty.

    have you went to edit->preferences->external tools, then from external script editor click on combo box and choose browse. Then go to usr/bin and select monodevelop ( some put mono in opt ). Restart unity.

    If this does work uninstall then reinstall mono. Then redo the step above.

    If libmono.so isn't getting deployed when you build your project, either something's going wrong with the build, or something went wrong with your Unity installation. Do you have libmono.so for each variation in Unity/Editor/PlaybackEngines/LinuxStandaloneSupport/ ?

    I just wanna point out that the path is Unity/Editor/Data/PlaybackEngines/LinuxStandaloneSupport/

    Anyway, to add to what Tak was saying, you can check if all the files are there by running this in a terminal (assuming Unity is installed in the /opt directory):
    ls -v /opt/Unity/Editor/Data/PlaybackEngines/LinuxStandaloneSupport/Variations/*/Data/Mono/x86*
    You should see libmono.so listed under each path.
