[olsr-dev] Re: [OLSR-users] Dot Draw segfaults on mipsel

[Andreas Tønnesen]

Ahh.. I found the problem. Some structs had not been updated to reflect 
new members from the link quality code. I've updated CVS, but since this 
takes some time to get to the public cvs I've attatched a patch. olsrd 
itself must be compiled with the USE_LINK_QUALITY symbol defined(as it 
is by default) for this to work.
