AFAIK, this never happens. The reduction is done mainly for the thing not to be too big in the memory while running. > In any case if you have a better idea on how to do this, maybe having a > statically built gdb, it would be welcome too. A statically built gdb is he way to go, IMHO. If you'd want a udeb for gdb, then the library reduction should take into account its dependencies (symbols). This would mean: - - either you make a custom image which uses mklibs-copy (no reduction) and you can use a regular binary or a gdb udeb which contains just the gdb binary (dynamically linked) - - build a custom image with gdb's needed symbols not stripped - but this means that gdb could not be used for regulaly built images. - -- Regards, EddyP ============================================= "Imagination is more important than knowledge" A.Einstein -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFR2c5Y8Chqv3NRNoRAhv0AJ9lmihF3fyS3OHr38zd4Hw7qeyPZwCg1l2q EaEljSty/gxAEMg7QTz7xFw= =Lowy -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
