I've tracked down a game named superhot and downloaded zipped Linux version. I unzipped it and there was a directory named SUPERHOT-LINUX_Data and file with extension .x86. I went to properties and ticked "can execute". But the file still doesn't start. All i can see is bunch of processes starting upon clicking on that file. Their names starts with unity.

Should i install some libraries or something?

Thanks for advice

Edit: I've tried as damien said and mono installed successfully, but still nothing. Then i tried running that file from terminal:


and it returned:

./SUPERHOT-LINUX.x86: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

I guess something is missing?

  • I downloaded the zip file and had a look in the superhot-linux-data directory and it appears you need mono. Try sudo apt-get install mono-runtime then repeat what you tried and report the results to your question

I solved by installing these libraries:

$ sudo apt-get install libglu1-mesa:i386 libxcursor1:i386

You can print shared library dependencies with:

  • 1
    the ":i386" makes the difference..

  • You can improve your answer by explaining why, as @Tapper said, is i386 part important.

Yes, your system lacks that library (libGLU). In this case it is available in the repositories so you just need to run

$ sudo apt-get install libglu1-mesa

If you find similar errors you can try to find the needed package using apt-file. In this case, to search packages that have the file libGLU.so.1:

$ apt-file search libGLU.so.1
libglu1-mesa: /usr/lib/x86_64-linux-gnu/libGLU.so.1
libglu1-mesa: /usr/lib/x86_64-linux-gnu/libGLU.so.1.3.08000
libglu1-mesa: /usr/lib/x86_64-linux-gnu/libGLU.so.1.3.08004
