[Buildroot] Buildroot 2010 rc2 fails to build

[Buildroot] Buildroot 2010 rc2 fails to build

[Chris Kerios]

Hi,
I am building for a Geode LX using the latest release candidate - rc2.  I am
getting a failure when buildroot is building the gdb 6.8 packages.  It is
trying to resolve an undefined reference to "usleep".  The output is
attached below.  I redid my .config to not build the gdb packages and it
then goes on a ways and fails when building busybox with the same unresolved
reference to usleep.  I get successful builds with the 2010.02 release with
no changes in my config file.  Any ideas???

Also, I noticed with the rc2 release the uClibc is prompting me for answers
to questions.  Is this expected to be expected as I don't have to do this
for the 2010.02 release?

Chris

As reported previously, I had this issue when I used my 2010.02 buildroot,
kernel and busybox .config files with 2010.rc1 and just accepted the default
options for missing configuration items.  However if I regenerated my
.config from scratch using 2010.05 rc1 menuconfig (selecting all the
same/equivalent options) then this build issue went away

I think it is this update of uclibc options that is the problem.  I have not
examined the differences and dug deeper to resolve but you might like to ;)

I also asked the list if carrying forward .configs like this was an
acceptable way to move to newer versions of buildroot - it would seem at
least you and I are doing it!

[Buildroot] Buildroot 2010 rc2 fails to build

[Chris Kerios]

Thanks Will.

Sorry, my bad everyone, I didn't look far enough down in the mail archive to
see your thread where this is resolved with a config file change.  I blew
away my .config file and rebuilt a new one and all the problems with usleep
and the uClibc build went away.  However, what did blow up was the MTD
utilities build.  I am researching that right now.  I thought I saw
something in the mail archive but it looked like it was just saying to turn
it off for the time being.  If this is the case I am not sure if that is
going to work for me as I am developing on a compact flash card and using
JFFS2 for a file system.  Still learning.  Thanks.

Chris

Ok, so the problem was that you used the uclibc 0.9.30 config with
uclibc 0.9.31.

JFFS2 on compact flash? That doesn't sound right. JFFS2 is meant to be
used on raw flash, not on
flash-with-a-microcontroller-pretending-to-be-a-disk like a compact
flash card is.

The mails about mtd problems was with the new busybox applets, not the
normal mtd package.

Please send some more info if you still have problems building it
(busybox .config, exact error message).

[Chris Kerios]

Thanks Peter.
Yes, I am building fine now on the Geode.  The build is configured with all
the latest versions of the software for uClibc, busybox and kernels.  I also
have a AVR32 NGW100 that I am beginning to work on that I will be testing
buildroot on next.  I will let eveyone know how that one goes and cry for
help when I get lost in buildroot...haha.

Regarding the JFFS2 and MTD utilities.  I just learned online this week that
none of it applies to working with a CompactFlash card, so thanks for
reinforcing that piece of knowledge for me.  One less thing to worry about.
What I was wondering about was since I have this configuration Geode
w/Compact Flash.  What does the embedded community recommend be used as a
file system, ext2/3 or something else.  Although we will run most of the
system and application in RAM we want our application to write some data to
disk (Compact Flash) and back across the network in the event of failures,
etc.  We also are going to be running in a relatively "high availability"
environment so I am concerned about the long term operation of the CF over
time.  Does anyone have any thoughts on this?  I know this isn't the right
mail list for this type of question but I know the world of embedded
developers out there are using this tool extensively so you all obviously
have thoughts and opinions on this.

Great tool!  Thanks,
Chris

EXT2 - The journal updates from EXT3/4 are bad for the lifetime of the
CF.

And make sure you mount it noatime to limit writes.

BR git master does not build atngw100_defconfig at the moment.
I submitted a patch yesterday that updates atngw100_defconfig so that
it builds again.
I hope it will be included in the 2010.05 release. Maintainers?

BTW, atngw100_defconfig works fine in version 2010.02.
