execute a program file

ernst · 08-27-2008, 07:51 AM

Hi,
I try to run a program:

~/tmp$ ./vwlinux86gui
bash: ./vwlinux86gui: No such file or directory

~/tmp$ ls -l ./vwlinux86gui
-rwxrwxrwx 1 ernst ernst 4079840 2008-08-26 00:45 ./vwlinux86gui

I do not understand why bash does not find the file and not execute it!

i.e
~/tmp$ chmod -x ./vwlinux86gui
~/tmp$ ./vwlinux86gui
bash: ./vwlinux86gui: Permission denied

Now it did find it and gives the correct error message

I hope this is very simple, but I can't see it.

Thanks
Ernst

Maybe vwlinux86gui is a script with a shabang line which refers to an interpreter which is not installed.

Do this:

Code:

head -n 4 vwlinux86gui

If you see something like this:

Code:

#!/usr/bin/wish

...and there is no wish installed, then that is the problem.

You might also see it like this:

Code:

#!/bin/sh

exec wish "$0" "$@"

Of course, it might not be wish exactly, but some other interpreter.

head -n 10 vwlinux86gui

shows on first line:
ELF04��<4 ((%444��^

then unprintable characters and later:

/lib/ld-linux.so.2

On this box I have ld-linux-x86-64.so.2 instead of ld-linux.so.2
This must be the problem.

Thanks

Linux x86 (32-bit) is supported, § 7.1 :
http://www.cincomsmalltalk.com/docum...seNotes7.1.pdf

Ask matthewg42 for the possibility to use it
on your system. (64-bit system)

I know nothing about 64-bit apps and if they run or not on a system of the other type.

Thanks to everyone,
The turning point was to realise that I am trying to run a 32 bit app on a 64 bit os.
Here is an article about this
http://www.debian-administration.org/articles/534

With this in mind I did:
apt-file --architecture i386 search libX11.so.6
which points to two packages: libx11-6 and ia32-libs

The first one was already installed. After installing the second one VisualWorks runs.
