Re: [PLUG] "command not found" errors with different distro. 32-bit vs 64-bit?

Thanks, Pat. I'm not sure how to interpret the following:

-------------------------
sparky ut # file ut
ut: POSIX shell script, ASCII text executable
sparky ut # cd System
sparky System # file ut-bin
ut-bin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.0.0, stripped

sparky ioquake3 # file ioquake3
ioquake3: POSIX shell script, ASCII text executable
sparky ioquake3 # file ioquake3.i386
ioquake3.i386: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped
sparky ioquake3 # ldd ioquake3.i386
not a dynamic executable

sparky System # ldd ut-bin
not a dynamic executable

I would expect to get a different message other than "not found", but
you may be on to something with the 32-bit libraries.

If I were working with this problem, I'd first try "file" on these
files, to see if they're even recognized as executables. Then I would
also try running "ldd" on them to see what shared libraries they're
using (and, perhaps, whether any are missing). The latter might give
you a hint about any 32-bit libraries you need to install on your 64-bit
system.

After using Debian stable for many years (and many upgrades-in-place)
I decided to do a fresh install. I made a backup of my /usr/local
directory and copied some of its contents back onto the new system.
Now, when I try to run the games, I get a "command not found" error.
This occurs from the command line, when I am in the directory where
the script or executable is located, and results are the same whether
I'm a regular user or root.

Example 1:
-----------------------------
pwd
/usr/local/games/ioquake3

(ioquake is a shell script which calls ioquake3.i386, an executable.
Both have executable bit set.)

sh ioquake3
ioquake3: 48: exec: ./ioquake3.i386: not found

whereis ioquake3.i386
ioquake3: /usr/local/games/ioquake3
----------------------------
Example 2:
----------------------------
pwd
/usr/local/games/ut

(ut is a a shell script which calls System/ut-bin, an executable. Both
have executable bit set.)

sh ut
ut: 84: exec: ./ut-bin: not found

cd System
pwd
/usr/local/games/ut/System
ls|grep ut-
ut-bin

./ut-bin
bash: ./ut-bin: No such file or directory
-----------------------------

Old system: Debian squeeze i386
New system: Linux Mint 13 amd64 (which is based on Ubuntu 12.04, an
LTS release)

In both cases I am using KDE.

Is this an issue with 32-bit executables on a 64-bit os? If so, is
there a way to fix it so I can run my "antique" games? If not, what
am I doing wrong?

Thanks for any ideas,
Greg
