Re: Is there a way to make static executable out of ELF shared one?

Hi
It´s possible to recompile all the sources as static, but your ramdisk will
be a lot bigger than compiling as shared and adding libc to the ramdisk...
it´s easier, too.. you can simply copy all what is needed (and shared
libraries, which you can find running ldd on each executable you want on the
ramdisk) to a new rootfilesystem, and then gzipping it (better done on a
loop). In addition, you can compile packages as Busybox, which provide a lot
of  basic functionality in a very small footprint. In as little as 2-3 Megs
you can build a very powerful system, without bells & whistles as X, but
with networking support and all the servers you may need (telnet, ftp,
http), and useful stuff. If you are really tight of space, you can build a
complete (well, almost) system in a 1.44M floppy, including a 2.4.x
kernel...
