Hi,
Attached are some patches that allow openospfd to be compiled in the
absence of IFT_CARP on recent systems. (conditional on not being defined
to allow it compile if there is a system version with it defined).
The kroute.c patch should include the existing kroute.c patch.
I've also added an include for stdlib.h to the parse.y patch to make
clang happy.
I aven't had a chance to verify that the software works correctly with
these patches (i.e. that nothing else has changed) but at least it
builds and installs properly.
Hope they are of some help.
Brian Scott
