[OLSR-users] interaction between mobile ipv6 and olsr

[Andreas Tønnesen]

Hi Ignacio,

Thanks for reporting this. Here is Thomas' core dump recepy, could
you follow it and post the files?
Thanks.

1. Change to the olsrd source code directory.

2. Say "make uberclean; make" to force a complete rebuild
and to build olsrd.

3. Do NOT say "make install". "make install" would strip the debug symbols
from the compiled executable and from the plug-ins in order to reduce the
size of the executables and the plug-ins. But we need the debug symbols.

4. Manually copy the olsrd executable and the plug-in .so files(if you
use any) to the appropriate directories. ("/usr/sbin" and "/usr/lib" by
default)

5. You now have an olsrd executable with debug information and plug-ins
with debug information installed.

6. Say "ulimit -c unlimited". This will allow olsrd to dump core.

7. Run olsrd and make it crash.

8. Create a TAR of the (1) olsrd executable, (2) the plug-in .so files,
(3) the core file, and send it to me. This will enable me to find out
where exactly the crash happens.

Thanks,
-Thomas
