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

[Joseph E. Sacco, Ph.D.]

OK... live and learn. 
[When all else fails, read the documentation... :-)]


I took a closer look into mtd-utils.  You may wish to consider updating
the repository to use mtd-utils-1.0.0 [30-Apr-06], rather than the 2005
snapshot with patches from March-2006.


I pulled mtd-1.0.0 from the infradead.org GIT repository,

http://git.infradead.org/?p=mtd-utils.git;a=commit;h=7ddeed0c79a524f222d2911c023781c88f63eaf7

Version 1.0.0 has the newer layout seen in version 1.0.1 but does not
require libacl or xttr. 

Version-1.0.0 builds without incident on a lintel box using

     gcc-3.3.2-glibc-2.3.2  [32 bit PPC]

cross-tool chain, producing the following set of [stripped] executables
