[SOLVED] Bash says file does not exist, BUT file does exist

jlight2011 · 2011-11-30 01:18:10

Hi Everyone
I am trying to run this engineering application that I was recently given by my department. Arch is (obviously) not on the official support list and I really really do not want to switch (to something like CentOS).

The issue is this. The program runs a license utility that is located in a sub-directory, bash says that the utility does not exist

can't exec /home/jlight/Fluent/Fluent.Inc/license/lnamd64/fluentlm-helper90: No such file or directory

But the file (and directory) exists as seen below

ls /home/jlight/Fluent/Fluent.Inc/license/lnamd64

fluentlm-helper90 liblic90.so license.dat lmstat

Why is this happening?

Thank you all!

Cheers!

JLight

Please use code tags, and please also supply the actual command you run, not just its output.

Also, "ls -l" not just "ls":

ls -l /home/jlight/Fluent/Fluent.Inc/license/lnamd64

I'm just guessing here: you're on a 32-bit system and this is a 64-bit executable? Is this file executable? What are the permissions - root only?

The application is

[jlight@jlightDell lnamd64]$ ./license_checker 
*** can't exec /home/jlight/Fluent/Fluent.Inc/license/lnamd64/fluentlm-helper90: No such file or directory

And

[jlight@jlightDell lnamd64]$ ls -l /home/jlight/Fluent/Fluent.Inc/license/lnamd64
total 1136

I am on a 64 bit OS. The file is executable, the permissions are shown in my second post. If the architecture/permission was not correct wouldn't the error message be different. Why say file missing?

Is this license_checker file a binary, or a bash script? If it's a bash script, you might be able to tease out an offending command it's trying to run.

It is a binary. I did try going to the location that indicated it does not exist. I then tried running the application from it to see if it was possible (may be even see if it give out some error messages). So I did this

[jlight@jlightDell lnamd64]$ cd /home/jlight/Fluent/Fluent.Inc/license/lnamd64/
[jlight@jlightDell lnamd64]$ ls -l
total 1136
-rwxr-xr-x 1 jlight users 696612 Jun 17  2006 fluentlm-helper90
-rwxr-xr-x 1 jlight users  29232 Jun 17  2006 liblic90.so
-rwxr-xr-x 1 jlight users   3154 Apr 29  2011 license.dat
-rwxr-xr-x 1 jlight users 422336 Feb 26  2003 lmstat
[jlight@jlightDell lnamd64]$ ./fluentlm-helper90 
bash: ./fluentlm-helper90: No such file or directory

The offending file 'fluentlm-helper90' seems to be problem and it too is a binary.

Also, I wouldn't worry too much about this being Arch instead of CentOS. I doubt the problem is with which package management system you happen to be using.

The application is no longer supported by the company and my Uni tech support will complain about Arch. This is more of the issue than the package management system.

karol · 2011-11-30 02:07:02

What's the output of

file fluentlm-helper90

?

What I mean is, before your uni tech support refuses to help, the onus is on them to prove that your specific distro is too alien for them to understand. Linux is linux. If they can support one, they can support them all. They are the trustees and you are the beneficiary. They must bow to your every whim ;-)

What do you get from running the following?

file *

I think there is a MLUG meeting tonight. Some problems are better solved face-to-face. Maybe you could go along and see if anyone wants to help?

I think you pointed out the issue. This is the output i get

[jlight@jlightDell lnamd64]$ file *
fluentlm-helper90: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, stripped
liblic90.so:       ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped
license.dat:       ASCII text, with CRLF line terminators
lmstat:            ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.0.0, stripped

I do not have 320bit libs on my arch thought I could get them. thought not sure which ones I will need. ldd the following

[jlight@jlightDell lnamd64]$ ldd fluentlm-helper90
	not a dynamic executable

The way i see it, there are two binary files (fluentlm-helper90 and lmstat) that are 32bit ELF executables, but dynamically linked. So, they will search/need their 32bit libraries in order to execute. Try installing glibc 32bit and see what happens. Or ask your support team for 64bit and/or static linked files. Just by two cents.

This is correct. Installing at least some of the needed 32 bit dependencies will start to give better feedback (in the form of wrong ELF class messages). The method to get it running is as Thanoulis has recommended; Look at what dependencies that the executable needs and install the lib32 packages required. Enabling the multilib repo will take some of the work away.

jlight2011 · 2011-11-30 03:46:36

Installing the lib32-gcc-libs and lib32-glibc did the trick.

Thanks you all for helping me out.

Cheers!

I remembered a similar case for the very reason the error message is not very helpful, I find it confusing as hell.

Is using 'file' the best we can hope for or can somebody open a ticket somewhere?
