2009.05-rc3 released

Hi,

I've released RC3. Unless big issues are found, expect this to be the last release candidate before the release - So give it a good test.

Get it from here:

http://buildroot.net/downloads/buildroot-2009.05-rc3.tar.bz2

And report any issues found here or in the bugtracker.

The plan is to release the final 2009.05 release this weekend.

Bye, Peter Korsgaard

Does this release address the MPFR/gmp problem I reported a few days ago?

Thanks,
Adam

No, I unfortunately haven't had time to look into that.

The default linux-header for the tool chain was 2.6.29.4 but the default kernel itself was 2.6.29.2. The attached patch fixes that.

Thanks. Your patch was whitespace mangled - Could you please fix your mailer or use git send-email next time?

I've committed your patch by hand.

I have been trying to build buildroot with a ubifs image. I haven't quite got there yet, but there are some bugs associated with this version.

target/ubifs/ubifsroot.mk
$(call DOWNLOAD,"$(MKFS_UBIFS_URL)")

This should be a WGET, not a DOWNLOAD.

I have been trying to update the UBIFS support as this is now included in the mtd-utils package under the mkfs.ubifs.
ubifs also depends on e2fsprogs as there is uuid support needed in mkfs.ubifs. I have at least gotten ubifs to compile with a few changes here and there (mainly a change in mtd-utils makefiles to build mkfs.ubifs), but I haven't had time to get an image made yet.

I Paul,

I tried to fix the ubifs too a while back, but other things got in
the way. I was mainly interested in seeing if it compresses better than jffs2.
Anyway. I think the correct approach would be mimmic jffs2.mk,
don't download anything and let mdtutils build mkfs.ubifs for the host.

Kind Regards,
Thiago A. Correa

Thiago,

I agree, and thats the approach I am taking, I have managed to get it to build with these quick patches:

With this patch, I successfully get a ubifs image. I think... (not sure if I have touched other stuff unfortunately). Sorry if gmail wraps the patches, I can always send via an attachment if need be.

I am not 100% sure if this is what you meant by comparing the sizes of the images, but I have made a ubifs image, so I thought I would show the results.

I can't check what this equates to on a extracted image yet as I need to modify u-boot a fair bit to get this to work, as currently uboot doesn't build with ubifs support for the at91sam9xxx.

If you want the config I used to do further analysis just let me know.

Thanks - Will fix. I just gave it a test, and it seems like the upstream git tree is gone, so it won't help you much.

Hamish, I believe you were the one adding ubifs support - What is the situation with mkfs.ubifs? Is upstream mtd-utils nowadays like mkfs.jff2?

Seems like we'll have to make ubifsroot as broken for the 2009.05 release :/

Hi,

Oh, I fixed this in my tree at work I'm pretty sure, but obviously forgot to send in a patch. mkfs.ubifs is included in mtd-utils now, but you have to use the git version (it's not in an mtd-utils release).

I haven't kept up with official buildroot lately, especially since the switch to git. I'll see if I can send a patch to the mailing list tomorrow.. I can't get to my code right now.

Ok, that's a pity. The 1.2.0 release (that we don't even have in BR) is getting a bit old in the tooth (~1 year).

Thanks - Any specific problems with git?

Bye, Peter Korsgaard

Hi,

Anything wrong with Paul's patch? It does look better than what I was doing (duplicating the mkfs.jffs2 rules for a mkfs.ubifs).

Basically, what needs fixing is getting mkfs.ubifs for the host, it was previously built by ubifs.mk from a user's tree, and now it's in the main mtdutils tree as part of the distribuition. Unfortunally there is no release containing it yet.

Kind Regards,
