issue building iputils with uclibc.

I'm having problems compiling iputils with uclibc -

It works fine with eglibc. I posted this question before but didnt really get a good answer - can anyone help point me in the right direction?

IIRC the thread ended with Khem asking if UCLIBC_HAS_RESOLVER_SUPPORT='y' was in the uclibc configuration, the implication being that dn_comp is unavailable unless that is true. I'm not too familiar with how uclibc is configured and with only a brief glance at the recipe I can see the config seems to be automatically generated but I can't see exactly how additional options (beyond what gets added from DISTRO_FEATURES) would be added.

Khem, could you help out here?

go into the uclibc build tree and like kernel or busybox it will have a .config and grok that. If this is disabled then enable it in uClibc.distro file under uclibc recipes dir and rebuild uclibc. ideally these are distro knobs but for tests you can try it file ( uclibc uses kconfig )

I am unable to find a .config file in the uclibc build tree, can you be more specific about the path i might find it at?

UCLIBC_HAS_RESOLVER_SUPPORT=y doesnt seem to be present in the uClibc.distro file, i added it and tried running the build again with no success. Is there anything else I can try?

OK, so I just gave this build a try. You can find the configuration actually used in the build in TMPDIR/work/i586-poky-linux-uclibc/uclibc-0.9.32- r4.3/git/.config  (directory names may vary slightly depending on your build configuration).

With master, when I checked my version of that file, UCLIBC_HAS_RESOLVER_SUPPORT=y is set, so apparently this feature is getting enabled by default. However, when I did the same on edison (which uses uclibc 0.9.32 as opposed to 0.9.33) that setting is not present. Digging around I'm beginning to wonder if this option was perhaps added in uclibc 0.9.33, which if true would explain why it is not present when building uclibc in edison; but does that mean the underlying functionality was added in that version or just the option?

Cheers,
Paul

I got a question about how to change the startup application with Yocto for images generated with Yocto. And I googled it and landed on this page:
https://wiki.yoctoproject.org/wiki/FAQ:How_do_I_change_and_add_startup_scripts. Pretty good, someone was thinking about the same thing. But this page turns out to be empty. It seems that we need to get better than this.

I'm wondering if someone could update this wiki page or if the information is somewhere else...

Hi Autif, thanks a lot for providing the answer here. Since no one is showing any objections here, I updated the wiki page with your answer (https://wiki.yoctoproject.org/wiki/FAQ:How_do_I_change_and_add_startup). Please let me know if there is any suggestions or concerns.

I do not know of if the information is elsewhere - I had to find this information for my project

Here is my stab at it (already updated the wiki):

Q: How do I change and add startup scripts?

A: Edit meta/recipes-sato/matchbox-sato/matchbox-session-sato/session.
Of course, if you have your own meta-layer, append the matchbox-session-sato_0.1.bb recipe.

Disable 'matchbox-desktop' and 'matchbox-panel', however, do not disable 'exec matchbox-window-manager ...'

Don't forget to run your app as a background process

For example, the following code will start the fifteen game:

#matchbox-desktop&

# Lines containing feature-[foo] are removed at build time if the machine # doesn't have the feature "foo".

#START_APPLETS=showdesktop,windowselector #END_APPLETS=clock,battery,systray,startup-notify,notify #END_APPLETS=openmoko-panel-gsm,$END_APPLETS # feature-phone

#matchbox-panel --titlebar --start-applets $START_APPLETS --end-applets $END_APPLETS&

/usr/games/fifteen&

exec matchbox-window-manager -theme Sato -use_desktop_mode decorated -use_cursor $SHOWCURSOR $@

This rather narrow answer is only useful if you are running a MatchBox desktop.
There are many other deployment scenarios which would require a different approach.

That is true.

However, All over the Yocto Project's website - the common bitbake commands for an image is either core-image-minimal or core-image-sato. (core-image-sato-sdk also uses matchbox).

minimal does not start any app - not counting daemons and gettys

If the user chooses another window manager - they are/should be on their own.

I just assumed that we are not trying to document the init process (bootloader, kernel, initrd, inittab, init.d etc)

We are trying to answer a less experienced developer to replace the default window manager with their own app

There is a chance that I am not aware of the default application being other than matchbox. Can you please provide me some counter example?

Thanks, Autif. I guess I missed the last word for the link, but it's strange that the page was there. Anyway, I deleted mine.

Hi Song,

I thought that I already updated the wiki. It seems like you created an extra page. "_scripts" is missing from the link. It should be there.

Source:
https://wiki.yoctoproject.org/wiki/Category:FAQ

What I added days ago:

https://wiki.yoctoproject.org/wiki/FAQ:How_do_I_change_and_add_startup_scripts

What you added (which I think should be deleted):
https://wiki.yoctoproject.org/wiki/FAQ:How_do_I_change_and_add_startup

Agree?

Greetings.

Is there any possibility to make recipe which start and run application inside weston terminal when Yocto starts.

Tnx !
