32bit program still not running after installing ia32-libs on Debian Squeeze

Xerxes1121 · 06-01-2011, 05:42 PM

I have a Debian Squeeze x64 VPS that I have been renting and I'm having some trouble getting the 32bit version of the Ventrilo server to run.

Code:

root@226513:~/ventsrv# ls
LICENSE  ventrilo_srv  ventrilo_srv.htm  ventrilo_srv.ini  ventrilo_status
root@226513:~/ventsrv# ./ventrilo_srv
-bash: ./ventrilo_srv: No such file or directory

This being my first experience with a 64bit Debian installation I did some research and installed the ia32-libs package to get the 32bit libraries, but still it would only respond with "No such file or directory"

Code:

root@226513:~/ventsrv# dpkg -l "ia32*"

I found alot of people with this problem since Ventrilo only has 32bit Linux servers and this solution seems to work for everybody but me. EX:http://ubuntuforums.org/showthread.php?t=798157 Could it be because of a newer version of ia32-libs is not providing a library that is considered obsolete but Ventrilo still needs? Any advice would help.

Thanks in advance - Xerxes

Just to rule out the obvious, does the file have the execute bit set (post the ls -l output)?

Xerxes1121 · 06-01-2011, 06:02 PM

Yes, that was my first thought before x64

Code:

root@226513:~/ventsrv# ls -l
total 592
-rwxrwxrwx 1 500 500  14388 Nov 12  2007 LICENSE

Perhaps this link will be helpful in diagnosing exactly which libraries it's looking for. Judging by your dpkg output, I'm guessing you need one of the other ia32 libraries as well. You currently only have ia32-libs and ia32-libs-dev installed.

EDIT: most of that link is just explaining how 32 bit works on a 64 bit system. The interesting bit was using the ldd command and apt-file to see if you can track down the missing library.

According to the pages I need to find the shared libraries and add them to the directory of 32bit libraries. Sadly I cannot see the linked libraries in the file since it is an ELF executable

Code:

root@226513:~/ventsrv# file ventrilo_srv
ventrilo_srv: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped
root@226513:~/ventsrv# ldd ventrilo_srv
        not a dynamic executable

Code:

root@226513:~/ventsrv# strace -o strace.out -f ./ventrilo_srv
strace: exec: No such file or directory
root@226513:~/ventsrv# cat strace.out
1282  execve("./ventrilo_srv", ["./ventrilo_srv"], [/* 15 vars */]) = -1 ENOENT (No such file or directory)
1282  dup(2)                            = 3
1282  fcntl(3, F_GETFL)                 = 0x8002 (flags O_RDWR|O_LARGEFILE)
1282  fstat(3, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 0), ...}) = 0
1282  mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2aeed9137000
1282  lseek(3, 0, SEEK_CUR)             = -1 ESPIPE (Illegal seek)
1282  write(3, "strace: exec: No such file or di"..., 40) = 40
1282  close(3)                          = 0
1282  munmap(0x2aeed9137000, 4096)      = 0
1282  exit_group(1)                     = ?

I should probably mozy on over to the Ventrilo forums and see if I cant get the info from the developers.... but I doubt it

I wish I remembered enough detail to be more helpful on this. I half remember participating in some thread here in which the basic concepts that were revealed were that a temporary cover for some security flaw totally disabled use of 32 bit executables on 64 bit Linux.

I might be seriously misremembering and thus confused. But the symptoms in this thread seem like that same kind of thing. Some setting that the loader depends on to understand 32 bit executables has been disabled.

Edit: I found that other thread. It starts getting into real info at the 43'rd post here:
http://www.linuxquestions.org/questi...8/#post4273254

The problem in Today's thread is clearly different, now that I compare the two. But I think the place Valery Reznic suggested looking in that thread may apply here as well.

So you could use this command to start to investigate whether it is a related problem:
