I'm running Ubuntu 8.04.1 in VMware Fusion on my Mac. Ubuntu 64-bit (8.04.1) lin_26 gcc424_libc27 (I've also tried it on the 32-bit equivalent of the same OS) I installed an API that came with some command-line apps for testing. I have added their directory (libs and binaries) to my path. When I attempt to run one of these apps from anywhere on the system, it tells me it can't find it despite printing the exact path to the app. The following, for example, was run from my home directory: <user>@ubuntu:~$ listener -su: /home/<user>/API/bin/listener: No such file or directory If I go to the directory containing the app and attempt to run, it still says it can't find it. Any ideas why it can't find/execute the apps?

If it helps, here are the OS and file specs: Operating System: lin_26 Hardware: x86_64 Processor: 1x Intel Xeon CPU E5462 @ 3.2GHZ Compiler: gcc424_libc27 <user>@ubuntu:~/API/bin$ file listener listener: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), not stripped I've run the same apps on another machine without problems. Specs: | Operating System: lin_26 | Hardware: x86_64 | Processor: 4 x Dual-Core AMD Opteron(tm) Processor 2220 | Compiler: gcc346_libc234 | Redhat Version: Red Hat Enterprise Linux ES release 4 (Nahant Update 6)

That's usually caused by the program not having a needed library installed.
