Before upgrading to 10.10, I was able to execute a binary in my home directory simply by double-clicking it. Now when I double-click it, I am told that no program is installed to run that type of file.

Here is my attempt to make it run via the command line.

~/blender25$ ls -l
total 37272
-rwxr-xr-x 1 mac9416 mac9416 38076379 2010-04-22 00:58 blender

~/blender25$ uname -m
~/blender25$ file blender
blender: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped
~/blender25$ ./blender 
bash: ./blender: No such file or directory

As you can see, the file certainly exists, yet I am told that it does not.

This has happened with another binary; but with the other one I was given a permissions error. Running chmod +x on it got me past that error, but I still get "No such file or directory".

So, what is preventing execution of these binaries in my directory in 10.10?

  • This is very strange. What are the permission on the files? Can you give use the result of a 'ls -l' rather than just the result of 'ls'. – Nyamiou The Galeanthrope Dec 2 '10 at 7:59
  • Please provide the output from the following command: uname -m; file blender – João Pinto Dec 2 '10 at 9:45
  • Thanks for your questions! I've updated the command line output to include your commands. – Michael Crenshaw Dec 2 '10 at 14:39

You are trying to run a 32bit binary on a 64bit system:

The output of uname -m, x86_64, means that you're running a 64Bit system. However, the blender binary is a 32bit Binary: blender: ELF 32-bit LSB executable, Intel 80386 ....

The fact that bash says the file doesn't exist seems to be a bug that never got fixed, since I get the same message when I attempt to run a 64Bit binary on my 32Bit system.

  • Thanks for your answer! That seems likely enough to be the problem except that the same binary worked fine before I upgraded from 10.04 (and, of course, the architecture has not changed). Still, I will try a 64-bit binary and let you know how it goes. – Michael Crenshaw Dec 2 '10 at 17:22

    I believe there is a package that allows you to run 32Bit binaries on a 64Bit system... you might have to install that first. – user2817 Dec 2 '10 at 17:28
  • The 64-bit binary works, so this is the correct answer. Why the 32-bit binary stopped working, I don't know. I haven't found that package yet, but if I do I'll let you know how it goes. Thanks! – Michael Crenshaw Dec 23 '10 at 14:59

I had something like that happen to me once. It turned out it was a caching issue for the file system. Is the ~/blender folder on a different file system than the main one? (I presume that you have tried rebooting your computer)

  • Yes, I've rebooted. My home directory is on its own partition, encrypted. – Michael Crenshaw Dec 2 '10 at 14:33
