[Olsr-dev] How to enable logging in olsr2?

[Henning Rogge]

Hi,

after looking through your code I would say that your selfmade
makefile system is just incomplete. the oonf-API (and olsrd2) allow to
remove the code for the debug/info messages based on a set of compiler
defines. I would guess that you don't handle this part so debug/info
are not in the code you compile.

As a quick hack to test this I would suggest adding

-DOONF_LOG_INFO -DOONF_LOG_DEBUG_INFO

to your compilter options.
