Error compiling riot-os with ccn-lite package

#1

Hello,

I am trying to compile the riot-os in native system to checkout the ccn-lite features, but it is failing with the following message:

ccn-lite-riot.c:120:26: error: ‘CCNL_SUITE_NDNTLV’ undeclared here (not in a function) static int _ccnl_suite = CCNL_SUITE_NDNTLV; ^ In file included from ccn-lite-riot.c:190:0:

My makefile is the basic Makefile of hello-world with following line added USEPKG += ccn-lite

Any suggestions on what am I missing?

#2

Hi Nazmul,

I think this might be not well documented indeed.

You need to set some configuration options for CCN-lite via the Makefile. The folloing would work:

# tell CCN-lite to run on top of link-layer CFLAGS += -DUSE_LINKLAYER # mandatory to include the propoer headers CFLAGS += -DCCNL_UAPI_H_ # tell CCN-lite which TLV to use (only NDNTLV is supported so far) CFLAGS += -DUSE_SUITE_NDNTLV # again mandatory for now CFLAGS += -DNEEDS_PREFIX_MATCHING CFLAGS += -DNEEDS_PACKET_CRAFTING

Finally, I discovered that there is a unmodelled dependency from CCN-lite's shell commands in RIOT to the CCN-lite utils. Hence, you will need to add

USEMODULE += ccn-lite-utils

to your Makefile, too.

Cheers, Oleg

P.S. I would recommend to start with the ccn-lite-relay example instead as a starting point.

#3

Hi Oleg,

Thanks for your suggestions.

It compiles correctly if I don’t include USEMODULE += ccn-lite-utils

as it builds that automatically.

Including that line causes following error make[1]: *** /home/fadedreamz/riotos/RIOT/pkg/ccn-lite-utils: No such file or directory. Stop.

I will use the ccn-lite-relay example as the starting point.

Thank you again.
