The Makefile uses ctags to build a list of global identifiers
that should be exported in a dynamic library. As ctags has a
very simplistic way of handling preprocessor conditionals, it
cannot detect symbols that are not present on platform POSIX.
In particular, the Solaris ld chokes on the following:
Undefined first referenced
symbol in file
coap_pdu_from_pbuf ../.libs/libcoap-1.0.so
coap_packet_extract_pbuf ../.libs/libcoap-1.0.so
The easiest way to fix this is to tell ctags that is should
ignore these identifiers with option -I.
For POSIX, coap_tick_t is defined as unsigned long to support
timestamps in wallclock time. The rd uses ticks to make node
identifiers locally unique. As this is just one part of the
generated identifier, the timestamp's lower 32 bits are
sufficient.
After including the doc/ and the tests/ folder under the hood of the
autotools now adding the examples/ foolder too.
The user is now able to add the build of the example binarys if
configure is called with '--enable-examples' as option. The example
binarys will not be build by default!
Currently only 'coap-client', 'coap-server' and 'rd' is build.
The last changes to include/coap/{net,resource}.h and src/{net,resource}.c
create new symbols that exported via the libcoap library. By this a
update for the map file is needed.

Calling a shellscript within a Makefile is not POSIX compliant, it's
possible that it would not work on all platforms. But using the check
for ctags as a seperate target within the main Makefile is no problem
and easy to change.
This commit is a addition to 101efbfe69
coap_malloc_type() and coap_free_type() provide an abstract API for
dynamic memory management on different platforms. resource.c still
is in transition and needs more cleanup.
The CoAP resource management is based on uthash and utlist for
platform POSIX but used a custom list implementation for Contiki.
This modification replaces the list handling by utlist macros
entirely. A set of convenience macros has been defined to access
the resources stored in a CoAP context with respect to the
preprocessor symbol COAP_RESOURCES_NOHASH.
The parser iterator did not break up URIs correctly. As this
cannot be fixed easily, the parser iterator has been removed.
coap_split_path_impl() now operates directly on the message
buffer instead of the iterator abstraction.
This bug also caused t_parse_uri12() in the URI test suite
to fail.
* Removed tne preprocessor defines for coap_tick() and coap_clock_init() --
this made the code less readable and seemed to be of little use.
* Introduced the new type coap_time_t to represent wall clock time. On POSIX,
this is the number of seconds since the epoch, while on embedded systems
without a real time clock, this could be the number of seconds since the
last reboot. The new function coap_ticks_to_rt() is used to convert
coap_tick_t to coap_time.h. Currently, this is a division by COAP_TICKS_PER_SECOND
on all platforms.
* POSIX: coap_tick_t is now defined as unsigned long to avoid overflows in
coap_ticks().
The helper functions decode_segment() and check_segment() are private
functions in uri.c and thus should not be accessible from outside. For
simplicity, these functions have been copied to client.c.
As the libcoap sources have been moved to the sub-directory src it
must be added to the vpath. The header files now reside in include/coap,
so we need an additional -I compiler flag for this.
The root path for libcoap is derived from the variable APPDS which is
set by $(CONTIKI)/Makefile.include. This is a bit fragile but the best
we have...
Made vpath %.c point to ../../src and repaired include path.
The common part of the Makefile has been moved to Makefile.common
to leverage Makefile creation for other platforms such as econotag.
Some compilers (clang, e.g.) just emit a warning that the tested
flags are not supported. As the macro does not recognize this,
we must pass -Werror as EXTRA_FLAG to exclude the unknown flags.
For Solaris, XPG4v2 must be enabled for ancillary data while the compiler flag
-std=c99 restricts the code to C99 and nothing else. To make this work anyway,
we have to use the following compiler flags:
-D_XOPEN_SOURCE=600 -D_XOPEN_SOURCE_EXTENDED=600 -D__EXTENSIONS__=1
