[Click] Unable to compile Click with the OpenFlow element

[Shrutarshi Basu]

Hi all,
I'm trying to compile Click with the OpenFlow element (
http://www.openflow.org/wk/index.php/OpenFlowClick) and against the standard
2.6.33 kernel. I run `.configure --enable-openflow` and `make elemlist` as
per the OpenFlow instructions but on `make install` I get a compile error
saying that <click/cxxprotect.h> is missing, even though I can see it in
include/click. Here's the complete error message:

/home/openflow/click/include/click-linuxmodule/include0/linux/unaligned/generic.h:5:3:
error: #error "missing #include <click/cxxprotect.h>"
fixdep: /home/openflow/click/linuxmodule/.elements.o.d is empty

Compiling and installing Click without the OpenFlow module seems to work
fine. Any ideas as to what could be wrong?
