Re: [Ltib] mtd-utils: dependencies and versions

[Joseph E. Sacco, Ph.D.]

Hi Stuart,

The reason I asked about the zlib dependency is that it is not listed in
the spec file for mtd-utils. 

I was "bitten" by this omission when I first attempted to build
mtd-utils manually using

    ltib --pkg mtd-utils --mode prep
        ltib --pkg mtd-utils --mode scbuild
        

As for suggested updates... 

zlib
----
You might want to look at the blurb on

    http://www.zlib.net/

and ponder over whether or not the performance and security enhancements
warrant moving from version 1.1.4 to version 1.2.3.


mtd_utils
---------
I agree with you about not updating because of the additional libacl
dependency.  Although this dependency effects only mkfs.jffs2, it does
so in a large way [acl & xattr stuff added]. When I get some free cycles
I will look into this more closely.
