It looks like your dependencies are not available as 32bit libraries, or if they do exist; or you do not have LD_LIBRARY_PATH set to accomodate them.

When you run 32/64/ there normally is some kind of dichotomy in the library tree

Code:

/usr/lib           <- default 64 bit
/usr/lib/lib32   <- 32 bit libraries

There are variations on this.

This is true for library trees in /opt, $ORACLE_HOME or anywhere else on your system.

What is the output of:

Code:

ldd my32bitapp

Resolve all of the 'not found' entries.

Next, for each library in the list produced above:

Code:

ldd libraryname

Resolve not found entries.

This is a dependency problem. And you may find libraries that require other libraries that require even more libraries.
