[Buildroot] problem with new package partimage

[Buildroot] problem with new package partimage

[Jomas Nash]

Hi everybody,

I tried to create a buildroot package of partimage (http://www.partimage.org
).
It is a backup/restore program for partitions.
After some patches I got it to compile under buildroot ( Latest 2010-11 ).

However, when I run partimage on my selfmade litle linux (intel i686) system
(kernel, buildroot, busybox, partimage (and dependencies))
the backup part works ok. But the restore fails.

When I run dmesg it gives:
[  276.515102] partimage[1997]: segfault at 0 ip b77123ee sp bf928384 error
6 in libuClibc-0.9.31.so[b76e8000+3b000]

Has someone an idea how to solve this problem ?
Is it partimage related or uClibc related?
Any help will be apreciated.


Here's some background information:

1. When I restore the backup with a static version of partimage (Compiled on
a "normal" system with libc ) the restore works.
2. With the buildroot version of partimage at the point where a popup should
apear (just before the restore starts), the system freezes for a few minutes
and then crashes.
3. partimage needs slang. The buildroot has an old slang-mini. Can this
cause the problem?
4. I had to patch partimage to comile it under buildroot. Here is the patch
that make it
possible to compile partimage under buildroot. ( Large file and WChar should
be enabled in buildroot )


Here is the patch:

[Buildroot] problem with new package partimage

[Jomas Nash]

Hi,

I updated the buildroot packages newt -> newt-0.52.12 and slang ->
slang2-2.2.2 (these are the most recent ones) and then I compiled partimage
again.
It did not help. The program crashes at the same point.

Anybody has a suggestion what to do?


Kind regards,

Jomas

[Buildroot] problem with new package partimage

[Jomas Nash]

Hi,

Lionel Landwerlin advised me to run the program under gdb (thanks for the
advice).
So I tried this but i get an error in gdb.

1. I start gdb:    gdb partimage
2. The debugger starts and I type:   run

Then I see an error message in gdb:  /root/exec   /usr/bin/partimage : No
such file or directory

partimage is in /usr/bin  , So how can I debug my program?
Please help.


Kind regards,

Jomas

[Buildroot] problem with new package partimage

[Jomas Nash]

Hi everybody,

I found another strange thing with partimage.
When I start partimage and run 'ps'  in an other terminal, I see that 3
instances of partimage are running.
like:


1117   partimage -S  etc...
1118   partimage -S
1119   partimage -S

All three lines have the same parameters
At my "normal" linux system (ubuntu) there is only one instance of partimage
when I start it


Has anybody an idea what can cause this?
It looks like partimge does not want to be compiled in buildroot.

Kind regards,
Jomas

Busybox ps probably show all the threads by default, while the normal
ps shows only processes and hides all their threads.

This sentence simply doesn't make sense. It's not because there is a
bug somewhere that "partimage does not want to be compiled in
Buildroot".

The uclibc config has some setting to make uclibc more compatible with
glibc. Try it.
