ramdisk size using montevista

ramdisk size using montevista

[John F. Davis]

Hello

I am trying to boot hardhat linux with a small ram disk.  However, libc is more
than 4 megs by itself.  Is there something obvious I can do/read?  I tried using
busybox, but that only makes the bin directory small.  I don't really know
what I should do about the /lib directory.

Strip the library.  It will remove symbols that are handy for
debugging, but leave the ones that are needed for dynamic linking.

Well, you could have purchased a subscription, and have already
called someone and received the answer.  Or, you could read the
documentation that comes with the distribution.  Or, you can
just use 'strip' and reduce the size to about 1 Mbyte or so.....
That will get you started, but I'm sure there are more questions
to come.

Read the FAQ, and use strip.

In addition to strip you'll probably want to rebuild glibc as well without
debug info and optimize for size (not that gcc does all that much with
-Os but it'll certainly be better than -g).
