Alexander Huemer f1a1da6c90 attempt to fix parallel build, improve AM logic 
The formerly existing make rule caused a race condition in parallel builds and
wrongly stated the .c files as targets, which caused make to execute the
rule twice (once for each target). This was actually only fallout of the
attempt to express the fact that those two files are generated by the rule.

The generated file ranap_ies_defs.h was moved by one make job, another
job then tried to access the file in the old location and failed.

parallel build verified with:
$ for i in $(seq 1 10)
do
	echo "XXXX iteration $i"
	git clean -xfd
	autoreconf -i
	./configure
	make -j${i} || break
done

Osmocom Iuh experimentation code
(C) 2015 by Harald Welte <laforge@gnumonks.org>

This code is a playground for implementing something along the lines of
the an Iuh interface of a HNB-GW.  The intent is to later integrate this
with OsmoNITB + OsmoSGSN, in order to have 3G capable 'network in the
box'.

h1. Building

As external library dependencies, you will need
* libosmocore from git://git.osmocom.org/libosmocore
* libasn1c from git://git.osmocom.org/libasn1c
* libsctp-dev (this is the package name in Debian)
* libosmo-netif from git://git.osmocom.org/libosmo-netif (sysmocom/sctp branch)
* libosmo-sccp from git://git.osmocom.org/libosmo-sccp (sysmocom/iu branch)

To bootstrap the build, in the root directory, run:

    autoreconf --install

After that, run the usual

    ./configure [options]
    make
    [sudo] make install

h1. Using

Note: osmo-iuh is in active development (December 2015, January 2016) so below
statements may outdate rapidly.

there's not much to use yet.  But if you run the 'hnbgw' executable,
it will open a listening SCTP socket and wait for incoming Iuh
connections.  It will accept any HNB-REGISTER-REQUEST, so the homeNodeB
should start to establish RUA and RANAP (which we haven't implemented
yet).

h1. Regenerating C code from ASN.1 source

In order to re-generate the C source code from the ASN.1 source,
you will need a modified asn1c which has the following features:
* APER support (the patch from Eurecom, or its forward-ported version
  from the aper branch of git://git.osmocom.org/asn1c)
* support for prefixing the generated types (aper-prefix branch of
  git://git.osmocom.org/asn1c)
