3 libcoap

#$ git clone git://git.code.sf.net/p/libcoap/code libcoap-code
$ git clone git://github.com/obgm/libcoap.git libcoap-code
$ cd libcoap-code
$ ./autogen.sh
$ ./configure --disable-examples

Build in other platform:

Contiki

If you have cloned the sources via git, you need to run ./autogen.sh to generate the build scripts. This step is optional when a source archive is used.

Next, say ./configure --with-contiki to prepare the Makefiles required to build libcoap as Contiki app. To make this work, libcoap usually is unpacked in the directory contiki/apps.

LwIP

Using libcoap with LwIP requires a hand-crafted Makefile. Please refer to examples/lwip/Makefile to see how this is done.

TinyOS

The usage of libcoap with TinyOS is documented in the TinyOS Wiki.
