I recently re-installed Ubuntu in 64 bit, (before I had it in 32 bit). I had the home folder on a partition and the system on another. So when I re-installed I kept my old home folder.
My problem is that now, my c++ executables that use the SDL are recognize as "shared library", and so I can't directly run them from nautilus. I searched for a solution, and found that it was caused by a bug of mime-type (see https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1639531), which consider each file marked as "position independent executable" (by gcc) as a "shared library".
As It seems that there's no way to make mime-type recognize it normally, I would like to be able to launch "shared libraries" files in nautilus (as they are runnable from a terminal). I tried to set the default program for this kind of file to an application called "Run Software" but when I try to launch it, nothing happens.
What is the right way to make nautilus to run a certain type of file and not to associate it with an application ?
