Hi

[Brecht Vermeulen]

Hi Robert,

we have also written some elements within an own package (as in
etc/package), this is not in elements/local, but maybe it can help :

1) the element has to announce itself with
EXPORT_ELEMENT(CopyDSCP)
in the .cc file (see the other elements)

maybe this solves already your problem

2) our Makefile looks like :
# Change these if needed
LINUXDIR = /usr/src/linux
CLICKDIR = /usr
 
 
CLICK_INCLUDE   = $(CLICKDIR)/include
# needed for click-buildtool
CLICK_BIN       = $(CLICKDIR)/bin

# {TARGET} #

PACKAGE = harmonics
TARGETS = $(PACKAGE).ko
 
all: $(TARGETS)
 
##############
# {ELEMENTS} #

ELEMENTS = copydscp.cc lookuponu.cc
 
copydscp.ko: copydscp.hh
 
lookuponu.ko: lookuponu.hh
 
K_OBJS = $(ELEMENTS:.cc=.ko) kpackage.ko kernelversion.ko

clean:
        -rm -f $(PACKAGE).ko $(K_OBJS) kernelversion.kd kpackage.kd
kpackage.cc $(ELEMENTS:.cc=.kd) 
 
.PHONY: all clean

3) for this module, you have to insmod the .ko file before
install_config


As written your mail, it seems as you have developed some MPLS elements,
are you going to share them with the Click router project, there is also
some interest at our premises for that I think.

best regards,
Brecht
