When I run the server for linux the response to me is...
ELF: command not found...
please, tell me what it means...
Bye

It means quite simply, the command you typed in is not valid, a command, or making any sence to linux

When you type a command, Linux will look in certain areas to execute it. These are generally described as PATHS. This means that it will not search the entire computer for the program. The search paths associated with your username do not have such a command. The search paths for root are the most extensive, so open a terminal, switch to root (su -), and try typing the command again. Usually, this will find it.

If it doesn't, use the Window Manager's search function (in Gnome, select the start "foot" and from the menu select "Search for files." Enter the command name in it.

A closing question: I noticed that you typed the command name in all caps. Most Linux commands aren't that way and Linux is case sensitive. In other words, ELF, Elf and elf are different names and Linux would not substitue one for the other. Generally, commands are all lower case. You might try that, too.

Good luck

ELF binaries are typically written for another version of libc when you recieve this error.

I don't really know what to do about it, but I believe that the issue is expected to be resolved with a module from the abi-utilities.

I faced the same issue attempting to run <a href="http:/www.blast.com"> Blast software </a> (I don't know it this will show up as a tag. I hope so) I receive the complete error:
-bash: ELF: command not found

I ran `ldd blast` to review the dependancies. I show libNoVersion as one of the libraries. . . libNoVersion? What is that?

(the tags you want are [ ] brackets, and they are like this:
[ url= ent.er-the-web-address-h.ere ] TEXT FOR LINK [ / url ]
but obviously take out the extra spaces)
