Ramdisk using libc5

Ramdisk using libc5

[Edson Ap. Seabra]

        I want to make a ramdisk image for a PPC board that provides
basic network services
such as ping, telnet, traceroute and ftp. I would like the final memory
image size less than 2 Mb. Only libc-2.1.2.so has 4 Mb.

Has  somebody  done this using libc5 ?

Try stripping all the debug info out--libc-2.1.2.so will be about 370k.

Ramdisk using libc5

["Jeffrey D. Kowing" <Jeff Kowing]

You need to strip libc-2.1.2.so, i.e.,

$ strip libc-2.1.2.so

to remove the debugging symbols.  It should reduce it to around 1 MB.

Thank You, Lucinda.

This helps a lot. The libc now has 1.03 Mb ... I guess libc still have a lot of
code that I don't need.  I have to find a easy way to strip them.

Edson.

There is a magic script named mklibs.sh which removes unused functions from     the shared C library in the Debian Boot Floppies package, at:
    ftp://ftp.us.debian.org/debian/dists/potato/main/source/admin/boot-floppies_2.2.16.tar.gz

Let us know how you go!

Graham

I am having two problems running the  "mklibs.sh":

1) The script asks for files libxxx_pic.a and I do not know how to generate or to get them...

2) The script calls a command "readlink" that is not available  in the Red Hat Linux 6.0

Beside this I have replaced many files from the directory bin by the busybox. I could save about 0.5M.

Regards.
Edson.
