bash: ./eclipse: cannot execute binary file

Question

i am working on Ubuntu10.10 OS and i have downloaded eclipse-jee-helios-SR1-linux-gtk-x86_64.tar.gz. my computer is 64 bit machine.

when i untar eclipse and try run ./eclipse from command line, it gives me above error.

when i run file eclipse , it gives me following information.

 eclipse: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses
 shared libs), for GNU/Linux 2.4.0, not stripped

Could someone help me to find out what is going wrong here

Thanks in advance for any help

Have you checked if that Linux installation is 64bit? While your processor may support 64bit mode, you may be running a 32bit OS. Check with uname -a. If you see something like i686 or i386 and not ia64 or x86_64 then you are running a 32bit system and cannot run 64bit binaries. – Recurve

yes, it is the problem , i downloaded 32 bit eclipse and, not it works fine. Thank you punnie – Calefactory

Answer 1

My bet is that you are using a x86 Ubuntu with a x86_64 JVM. To make sure your Ubuntu is 64 bits, run the following command:

$ uname -i

Phoneme

Not the JVM but the eclipse launcher at least. But since this is not a rights issue then you are probably running a 32 bit kernel (even on a 64 bit machine). – Gossett

it gave following output ::: Linux localhost 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 i686 GNU/Linux ::::My ubuntu os is 32 bit :) my java version is :::lib/<arch>/jvm.cfg (where <arch> is i386, amd64, sparc or sparcv9) – Calefactory

yup, your operating system is 32bit. either download the 32bit eclipse package or install a 64bit OS. – Recurve

yes problem solved, my os is 32 bit and 32 bit eclipse works fine. thank you everyone for spending your valuable time on this issue. – Calefactory

@Gossett That's weird... 32-bit kernel on a 64-bit OS? Why would that be the case? – Plautus

@Shurane nope, 64 bit machine/server with a 32 bit OS/Kernel – Gossett

Answer 2

I suspect a right problem chmod +x ./eclipse should help and if it does not ls -l eclipse

Gossett

hi gabuzeo, chmod +x ./eclipse didn't work, ls -l eclipse gave -rwxr-xr-x 1 kapila kapila 71162 2010-08-10 20:48 eclipse – Calefactory

hi Tyler this is seems to not working. it still give same message – Calefactory

Answer 3

You've downloaded the 64-bit version of Eclipse - you need to download the 32-bit one!
