[Olsr-dev] DL loading failed: undefined symbol OLSR Plugin

[Henning Rogge]

Arg...

okay, same message again in English. That happens when you have too many 
chat windows open at the same time.

I wonder if the problem has something to do with the fact that the 
plugin use ".cpp" and ".hpp" endings. I remember there was some 
"makefile magic" that was collecting symbols for OLSR, maybe its missing 
the files.

But its difficult to say, a lot of things have changed since 0.5.6R2.
