Here's more details and logs from previous problem:


~/ksymoops-2.4.9 >./ksymoops ~/projet/kernelspace/oops
ksymoops 2.4.9 on i686 2.4.21.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Then, i ve try to set arch and target (even if i don't use cross
compilation):
Here's what i get:

oops.c::67, the call to bfd_get_target()
        bt = bfd_get_target(ibfd);      /* Bah, undocumented bfd function */
is returning garbage.  Ask the binutils people why this is so.

I have try the latest binutils 2.13.1 with no success.

With this version, thoses two lines in the Makefile seems to be mutaly
exclusive:

STATIC := -Wl,-Bstatic
DYNAMIC := -Wl,-Bdynamic

After installing binutils 2.9.5.0.22, it links and work.


Thank you for your support: i've got my oops decoded :)

regards,

j.
