Re: [Ltib] mtd-utils and kernel 2.6.33

[Bruce]

Thanks Stuart,

I was able to pull the latest source, build and install like you said but that didn't help. I'm in a learning curve with NAND flash so I'm reaching a bit.

I reverted back to the current tool version. Good tip on removing .host_wait_warning*! I'll have to remember that. Did a distclean to pick up the new package the first time:)

I still don't get where ltib determines the host tools to install. Is there a .config file? Where does that magic happen?

Thanks,
Bruce

Hi Bruce,

First the reason the host/target have different pkg_map entries is
because the later (target) one depends lzo compression and I didn't want
to introduce that dependency to the host.  Maybe it's time to cave in on
that one.

Do you know if the later 20080618 version would solve your problem, or
do you need an even later one that that?

If you need a later one, then what you need to do is this:

* Create a new .spec file. e.g.  in
dist/lfs-5.1/mtd-utils/mtd-utils-20101117.spec

Make sure you set the version to something like the current ones (e.g.
20101117) as this will be used when deciding if version a > version b in
 the host rpm install stuff.

* Then you need to edit: config/platform/host/pkg_map and put in your
new mapping.

* Remove .host_wait_warning* so that the host package build gets
re-evaluated

* Run: ./ltib


BTW: you may run foul of the lzo dependency.  If so, install it from
your host's package manager.

Regards, Stuart
