To: ptxdist; +Cc: Alexander Aring
This patch adds the libcoap implementation [0]. The most common use of
this library is to use it with contiki os. That's one reason why the
current buildsystem isn't "well". The added patches replace the current
buildsystem with a better one. The replacement had the goal to made less
changes to the current libcoap implementation.
The libcoap implementation do a include of autoconf "config.h" header
file in the API headers. The patches adds a new libcoap_config.h with a
LIBCOAP_ prefix to all defines and replace the use of these defines in
the API headers. That's too not well but offers a workaround to make a
clean install of this library and other autotools software can use it.
I found in the current release some things which are broken like some
disable features in configure call and others things which are not well.
I don't fix it in the patches, I will try to send the fixes to the
maintainer of this project and hopefully it's fixed in the next release.
Libcoap is still the best known C implementation of the coap protocol,
but also it's a bleeding edge implementation of a draft [1].

+-
+-Defaults for the options are specified in brackets.
+-
+-Configuration:
+- -h, --help display this help and exit
+- --help=short display options specific to this package
+- --help=recursive display the short help of all the included packages
+- -V, --version display version information and exit
+- -q, --quiet, --silent do not print \`checking ...' messages
+- --cache-file=FILE cache test results in FILE [disabled]
+- -C, --config-cache alias for \`--cache-file=config.cache'
+- -n, --no-create do not create output files
+- --srcdir=DIR find the sources in DIR [configure dir or \`..']
+-
+-Installation directories:
+- --prefix=PREFIX install architecture-independent files in PREFIX
+- [$ac_default_prefix]
+- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+- [PREFIX]

+From 2527f690d79f2ec22ff93371fc1123249a749808 Mon Sep 17 00:00:00 2001
+From: Alexander Aring <alex.aring@gmail.com>
+Date: Sat, 29 Mar 2014 21:18:47 +0100
+Subject: [PATCH 2/8] libcoap: add new buildsystem
+
+This patch adds support for autotools buildsystem.
+
+The configure arguments can be:
+
+ --enable-debug
+ --disable-async
+ --disable-block
+ --disable-observe
+ --disable-query-filter
+
+the same like the real libcoap implementation.
+
+In addition I added a:
+
+ --with-max-pdu-size=COAP_MAX_PDU_SIZE
+
+to replace the COAP_MAX_PDU_SIZE define with a given number.
+
+Signed-off-by: Alexander Aring <alex.aring@gmail.com>

++#
++# SYNOPSIS
++#
++# AX_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
++#
++# DESCRIPTION
++#
++# This is a new variant from ac_prefix_config_ this one will use a
++# lowercase-prefix if the config-define was starting with a
++# lowercase-char, e.g. "#define const", "#define restrict", or "#define
++# off_t", (and this one can live in another directory, e.g.
++# testpkg/config.h therefore I decided to move the output-header to be the
++# first arg)
++#
++# takes the usual config.h generated header file; looks for each of the
++# generated "#define SOMEDEF" lines, and prefixes the defined name (ie.
++# makes it "#define PREFIX_SOMEDEF". The result is written to the output
++# config.header file. The PREFIX is converted to uppercase for the
++# conversions.
++#
++# Defaults:
++#
++# OUTPUT-HEADER = $PACKAGE-config.h
++# PREFIX = $PACKAGE
++# ORIG-HEADER, from AM_CONFIG_HEADER(config.h)
++#
++# Your configure.ac script should contain both macros in this order, and
++# unlike the earlier variations of this prefix-macro it is okay to place
++# the AX_PREFIX_CONFIG_H call before the AC_OUTPUT invokation.
++#
++# Example:
++#
++# AC_INIT(config.h.in) # config.h.in as created by "autoheader"
++# AM_INIT_AUTOMAKE(testpkg, 0.1.1) # makes #undef VERSION and PACKAGE
++# AM_CONFIG_HEADER(config.h) # prep config.h from config.h.in
++# AX_PREFIX_CONFIG_H(mylib/_config.h) # prep mylib/_config.h from it..
++# AC_MEMORY_H # makes "#undef NEED_MEMORY_H"
++# AC_C_CONST_H # makes "#undef const"
++# AC_OUTPUT(Makefile) # creates the "config.h" now
++# # and also mylib/_config.h
++#
++# if the argument to AX_PREFIX_CONFIG_H would have been omitted then the
++# default outputfile would have been called simply "testpkg-config.h", but
++# even under the name "mylib/_config.h" it contains prefix-defines like
++#
++# #ifndef TESTPKG_VERSION
++# #define TESTPKG_VERSION "0.1.1"
++# #endif
++# #ifndef TESTPKG_NEED_MEMORY_H
++# #define TESTPKG_NEED_MEMORY_H 1
++# #endif
++# #ifndef _testpkg_const
++# #define _testpkg_const _const
++# #endif
++#
++# and this "mylib/_config.h" can be installed along with other
++# header-files, which is most convenient when creating a shared library
++# (that has some headers) where some functionality is dependent on the
++# OS-features detected at compile-time. No need to invent some
++# "mylib-confdefs.h.in" manually. :-)
++#
++# Note that some AC_DEFINEs that end up in the config.h file are actually
++# self-referential - e.g. AC_C_INLINE, AC_C_CONST, and the AC_TYPE_OFF_T
++# say that they "will define inline|const|off_t if the system does not do
++# it by itself". You might want to clean up about these - consider an
++# extra mylib/conf.h that reads something like:
++#
++# #include <mylib/_config.h>
++# #ifndef _testpkg_const
++# #define _testpkg_const const
++# #endif
++#
++# and then start using _testpkg_const in the header files. That is also a
++# good thing to differentiate whether some library-user has starting to
++# take up with a different compiler, so perhaps it could read something
++# like this:
++#
++# #ifdef _MSC_VER
++# #include <mylib/_msvc.h>
++# #else
++# #include <mylib/_config.h>
++# #endif
++# #ifndef _testpkg_const
++# #define _testpkg_const const
++# #endif

It's not going upstream, so I dropped any files from this patch that are
overwritten later. Can you check that I didn't break anything while doing
that?
Thanks,

Maintainer don't want to use automake in his buildsystem, I think it
will never go into mainline of libcoap. There is also no mailinglist for
this project, I mailed with the maintainer private.
General problem:
The library buildsystem was made for static linking to a non dynamic
loading operation system.
I can try an alternative instead of reimplemnt the whole buildsystem.
Steps are:
1. Patch libcoap package to add a libcoap.pc file with static paths and
add CFLAGS with -D WITH_POSIX.
2. Compile shared libcoap library with make and -D WITH_POSIX
(There exists a way mainline to compile a shared library)
3. on make install, install it to static path usr/lib/ and
usr/lib/pkgconfig usr/include...
3.1. There is something special on header copy to usr/include:
copy a dummy header for config.h (I hope that should work).
Normally the config.h is created by autoconf and they included it
in every header but no header use config.h information in the header
files (I suppose). So we don't need patch 4/6 (libcoap: remove
include of config.h).
4. copy library, headers into LIBCOAP_PKGDIR.
Something in that way...
I think all option will be end in some hack. I can try to do the
alternative and then we looks if it's better or not, if you are
interested in.

I need some clarification mostly. You're replacing the whole build-system.
That's not something I want to maintain inside ptxdist. I can only accept
that if this will be upstream the next time we update the package in
ptxdist. So what's the upstream status of these patches?

Hi Michael,
ping.
I see you applied other patch "libzmq: add new package" already. Is
there something wrong with this patch or simple needs a little more time
to review? :-)

+-VAR=VALUE. See below for descriptions of some of the useful variables.
+-
+-Defaults for the options are specified in brackets.
+-
+-Configuration:
+- -h, --help display this help and exit
+- --help=short display options specific to this package
+- --help=recursive display the short help of all the included packages
+- -V, --version display version information and exit
+- -q, --quiet, --silent do not print \`checking ...' messages
+- --cache-file=FILE cache test results in FILE [disabled]
+- -C, --config-cache alias for \`--cache-file=config.cache'
+- -n, --no-create do not create output files
+- --srcdir=DIR find the sources in DIR [configure dir or \`..']
+-
+-Installation directories:
+- --prefix=PREFIX install architecture-independent files in PREFIX
+- [$ac_default_prefix]
+- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+- [PREFIX]
+-

+-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+-for instance \`--prefix=\$HOME'.
+-
+-For better control, use the options below.
+-
+-Fine tuning of the installation directories:

+Subject: [PATCH 3/6] libcoap: add new buildsystem
+
+This patch adds support for autotools buildsystem.
+
+The configure arguments can be:
+
+ --enable-debug
+ --disable-async
+ --disable-block
+ --disable-observe
+ --disable-query-filter
+
+the same like the real libcoap implementation.
+
+In addition I added a:
+
+ --with-max-pdu-size=COAP_MAX_PDU_SIZE
+
+to replace the COAP_MAX_PDU_SIZE define with a given number.
