Hi Konstantin,

due to some CFLAGS problem (related to lto) batctl-2013.4.0 does not
compile unless you apply the attached patch (you can save and put it in
the patches folder within the batman-adv package).


The new batman-adv/batctl-2014.0.0 already includes this fix.



Cheers,

Subject: [PATCH] batctl: Add CFLAGS to the linker step

The GCC manual states for different parameters that the options for compilation
must also be used when linking. The options for compilation are stored in
CFLAGS and added to LINK.o to fix the behavior.

Option which need this are for example -fPIC/-fPIE or -flto.
