Script cannot find existing file

Question

I am trying to run a script named sassetup in folder /usr/local/SASHome/SASFoundation/9.4 on a linux machine. The first two lines of the script are as follows.

eval 'exec `dirname $0`/perl/bin/perl5 -U $0 ${1+"$@"}'
    if $running_under_some_shell;

I get an error message saying

./sassetup: line 1: /usr/local/SASHome/SASFoundation/9.4/perl/bin/perl5: No such file or directory

The file in the error message actually exists because the command below

ls -lt /usr/local/SASHome/SASFoundation/9.4/perl/bin/perl5

outputs

-rwxr-xr-x 3 5402 users 790559 Jan 24  2002 /usr/local/SASHome/SASFoundation/9.4/perl/bin/perl5

The output of

uname -a

is

Linux 4.15.0-112-generic 16.04.1-Ubuntu SMP x86_64 GNU/Linux

The output of

file /usr/local/SASHome/SASFoundation/9.4/perl/bin/perl5

is

/usr/local/SASHome/SASFoundation/9.4/perl/bin/perl5: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, not stripped

The file /lib/ld-linux.so.2 does not exist. Two similar files, /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 and /lib64/ld-linux-x86-64.so.2, exist.

The output of adding LD_DEBUG=all before the command when running is as follows.

How do I make sure that the script finds this file?

Answer 1

Linux 4.15.0-112-generic 16.04.1-Ubuntu SMP x86_64 GNU/Linux

Your system is 64-bit.

/usr/local/SASHome/SASFoundation/9.4/perl/bin/perl5: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, not stripped

The application is 32-bit.

The file /lib/ld-linux.so.2 does not exist

You have to install the 32-bit versions of libraries to run 32-bit applications under 64-bit. Install glibc compiled for 32-bit. On my archlinux the package is called lib32-glibc .
