The Debian boot-floppies package has a script that does this sort of thing, I believe. Don't know how well it performs as compared to lipo-suction. Excerpt from 'boot-floppies/scripts/rootdisk/mklibs.sh': # Introduction: # When creating boot floppies, there is never enough room on the disks. # So it is important not to waste bytes on unnecessary code. # Shared Libraries contain many functions that are probably not used in the # binaries included in the boot disks, and copying the whole library is a # waste of space. # This utilitiy helps to reduce the necessary libraries to only include the # symbols needed to run a given set of executables. # # Features: # * Automatic detection of all necessary libraries, even for inter-library # dependencies, for a given set of executables. # * Automatic installation of all needed libraries and soname links. # * Automatic reduction of all libraries to minimal size for which PIC # libraries are provided. # # Requirements: # * Beside the shared libraries, you need libfoo_pic.a files for all # libraries you want to reduce. # * You need binutils (notably objdump and objcopy) installed.
