cannot run any binary files at all FC12 64 bit

kmacphail · 11-20-2009, 07:27 AM

I have recently installed FC12 64 bit. I have been using Fedora now since I first installed FC9 a few years back.

My main problem is that I am unable to execute any files at all using the ./filename command. I spent last night trying to run the ipod bootloader and all I kept on getting was the message: unable to run binary file. I used the command chmod +x ipodpatcher before attempting to run it, but with no luck. After a while of frustration and a few suggestions online I booted up my Ubuntu OS and the file ran first time. Am I missing a program on FC12? Do I need to install something else?

I feel it may be simple, however I have never experienced this problem before using Fedora. Any suggestions?

is there any chance of you pasting the output from the attempt to run this or any file?

Is Ubuntu 32 bit or 64 bit? Is ipodpatcher 32 bit or 64 bit? Maybe you are missing part or all of the multilib support in FC12.

The output from the following commands might give us a better idea of the nature of the problem:

Code:

file ipodpatcher

Code:

ldd ipodpatcher

Thanks for the swift response guys.

Here you go:

Quote:

[kev@kev-pc ipod mod]$ sudo ./ipodpatcher
./ipodpatcher: ./ipodpatcher: cannot execute binary file

johnsfine: ipodpatcher is the 64bit Linux version and both FC12 and Ubuntu are 64bit

Johnsfine, here is the info you requested (the same file was used for Ubuntu):

Quote:

[kev@kev-pc ipod mod]$ file ipodpatcher
ipodpatcher: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped

[kev@kev-pc ipod mod]$ ldd ipodpatcher
not a dynamic executable

I'm trying to think of a second explanation for the combination of output you got from file and ldd. I haven't thought of one yet. Maybe some Fedora expert is reading this thread and can offer that second explanation.

You already contradicted the obvious explanation (that you're on a 32 bit version of Linux), but just to be sure, please try this command on the system where you got that strange result from ldd.

Code:

uname -a

what about attaching strace??

Code:

strace ./ipodpatcher

kmacphail · 11-20-2009, 01:10 PM

Johnsfine, uname -a gives the following output:

[kev@kev-pc ipod mod]$ uname -a
Linux kev-pc 2.6.31.5-127.fc12.i686 #1 SMP Sat Nov 7 21:41:45 EST 2009 i686 athlon i386 GNU/Linux

CentOSboy after an install of strace I get this output:

Quote:

Each of those independently tells us you are running a 32 bit build of Linux. You cannot run 64 bit programs on 32 bit Linux.

We are still talking about that system, right? The one that you think is 64 bit FC12? The uname output tells us it is 32 bit FC12 (the strace output alone would just tell me it is some 32 bit x86 Linux).

Assuming you don't yet understand how you ended up with a 32 bit build of Linux, you probably should tell us some things about where you got "64 bit" FC12 and how you installed it.

I downloaded the system (what I believed to be 64 bit) from the fedora website. I am now going to download it again and do a reinstall. Thanks for your help folks, this is odd, anyway mistakes happen. Thanks

Before going to the effort of reinstalling, you ought to tell us the URL you are downloading from. Maybe you are misunderstanding something there and downloading 32 bit again.

Edit: I looked at the Fedora web site and it looks like it would be hard to misunderstand. The download page I found was
http://mirrors.kernel.org/fedora/rel...ra/x86_64/iso/

That claims unambiguously to be FC12 64 bit and the 32 bit alternative was pretty unambiguously 32 bit.

The file that I downloaded and burnt onto CD had the term 86_64 and Fedora 12 in the title, I may be jumping to conclusions, but I thought that this would mean the 64 bit version of Fedora 12. Anyway I have now downloaded it again and installed the system, Fedora is now up and running in 64 bit mode. After an hour trying to figure out why my video driver wasn't loading, I had to eventually blacklist nouveau (what a hassle that caused), I now have my system running as I would like it. Thanks to everybody for their help.
