Hi Chris,

   You need to look at the external symbols being exported by your program.  I think "objdump -t|--syms" would be able to show you this.

Example:
hades:~ # objdump -t  /usr/local/bin/pan | more

/usr/local/bin/pan:     file format elf32-i386

SYMBOL TABLE:

08048108 l    d  .note.ABI-tag	00000000

0804a8dc l    d  .dynsym	00000000

080590bc l    d  .gnu.version_r	00000000
....
