Re-compiling libraries to save space in chroot jails

[bmulvey]

Hi All,

I am trying to re-compile some libraries (such as libc.a) to be smaller so that I can put them in multiple chroot jails for multiple ftp home directories.

I sucessfully did this about 3 years ago, but can't for the life of me remember how. I am in the middle of an Aix upgrade to 5.1 from 4.3.3 MU08 so I need to build new libraries.

I know that "ar" uncompile and recompile the libraries to the object code and back to the (smaller) library.

What I can't remember is how to find out the object code that a particular program uses (ls for instance).

Any ideas would be greatly appreciated.

Thanks

Brian
