  1. Release Contents

The Portable SDK for UPnP Devices is an SDK for development of UPnP device and control point applications. It consists of the core UPnP protocols along with a UPnP-specific eXtensible Markup Language (XML) parser supporting the Document Object Model (DOM) Level 2 API and an optional, integrated mini web server for serving UPnP related documents.

  1. Package Contents

The SDK for UPnP Devices contains the following:

README This file. Contains the installation and build instructions. LICENSE The licensing terms the SDK is distributed under. NEWS Changes and new features. ixml\doc The files for generating the XML parser documentation from the source code. ixml\inc The public include files required to use the XML parser. ixml\src The source code to the XML parser library. threadutil\inc The public include files required to the threading utility library. threadutil\src The source code to the threading utility library. upnp\doc The files for generating the SDK documentation from the source code. upnp\inc The public include files required to use the SDK. upnp\src The source files comprising the SDK, libupnp.so. upnp\sample A sample device and control point application, illustrating the usage of the SDK.

  1. System Requirements

The SDK for UPnP Devices is designed to compile and run under several operating systems. It does, however, have dependencies on some packages that may not be installed by default. All packages that it requires are listed below.

libpthread The header and library are installed as part of the glibc-devel package (or equivalent).

Additionally, the documentation for the SDK can be auto-generated from the UPNP.H header file using DOC++, a documentation system for C, C++, IDL, and Java*. DOC++ generates the documentation in HTML or TeX format. Using some additional tools, the TeX output can be converted into a PDF file. To generate the documentation these tools are required:

DOC++ The homepage for DOC++ is http://docpp.sourceforge.net/. The current version as of this release of the SDK is version 3.4.9. DOC++ is the only requirement for generating the HTML documentation. LaTeX/TeX To generate the PDF documentation, LaTeX and TeX tools are necessary. The tetex and tetex-latex packages provide these tools. dvips dvips converts the DVI file produced by LaTeX into a PostScript* file. The tetex-dvips package provides this tool. ps2pdf The final step to making the PDF is converting the PostStript into Portable Document Format. The ghostscript package provides this tool.

For the UPnP library to function correctly, networking must be configured properly for multicasting. To do this:

route add -net 239.0.0.0 netmask 255.0.0.0 eth0

where ‘eth0’ is the network adapter that the UPnP library will use. Without this addition, device advertisements and control point searches will not function.

  1. Build Instructions

CORE LIBRARIES

The in the examples below, replace $(LIBUPNP) with “libupnp-x.y.z”, with x, y, and z corresponding to the version of the library that you have.

All pieces of the SDK are configured and built from the $(LIBUPNP) directory.

% cd $(LIBUPNP) % ./configure % make

will build a version of the binaries without debug support, and with default options enabled (see below for options available at configure time).

% cd $(LIBUPNP) % ./configure CFLAGS=”-DSPARC_SOLARIS -mtune=<cputype> -mcpu=<cputype>” % make

will build a Sparc Solaris version of the binaries without debug support and with default options enabled (see below for options available at configure time). Please note: <cputype> has to be replaced by a token that fits to your platform and CPU (e.g. “supersparc”).

To build the documentation, assuming all the necessary tools are installed (see section 3) :

To generate the HTML documentation:

% cd $(LIBUPNP) % make html

To generate the PDF file:

% cd $(LIBUPNP) % make pdf

A few options are available at configure time. Use “./configure –help” to display a complete list of options. Note that these options may be combined in any order. After installation, the file <upnp/upnpconfig.h> will provide a summary of the optional features that have been included in the library.

% cd $(LIBUPNP) % ./configure –enable-debug % make

will build a debug version with symbols support.

To build the library with the optional, integrated mini web server (note that this is the default):

% cd $(LIBUPNP) % ./configure –enable-webserver % make

To build without:

% cd $(LIBUPNP) % ./configure –disable-webserver % make

The SDK also contains some additional helper APIs, declared in inc/tools/upnptools.h. If these additional tools are not required, they can be compiled out:

% cd $(LIBUPNP) % ./configure –disable-tools % make

By default, the tools are included in the library.

To further remove code that is not required, the library can be build with or with out the control point (client) or device specific code. To remove this code:

% cd $(LIBUPNP) % ./configure –disable-client % make

to remove client only code or:

% cd $(LIBUPNP) % ./configure –disable-device % make

to remove device only code.

By default, both client and device code is included in the library. The integrated web server is automatically removed when configuring with –disable-device.

To build the library without large-file support (enabled by default) :

% cd $(LIBUPNP) % ./configure –disable-largefile % make

To remove all the targets, object files, and built documentation:

% cd $(LIBUPNP) % make clean

CROSS COMPILATION

To cross compile the SDK, a special “configure” directive is all that is required:

% cd $(LIBUPNP) % ./configure –host=arm-linux % make

This will invoke the “arm-linux-gcc” cross compiler to build the library.

SAMPLES

The SDK contains two samples: a TV device application and a control point that talks with the TV device. They are found in the $(LIBUPNP)/upnp/sample directory.

To build the samples (note: this is the default behaviour):

% cd $(LIBUPNP) % ./configure –enable-samples % make

will build the sample device “$(LIBUPNP)/upnp/upnp_tv_device” and sample control point “$(LIBUPNP)/upnp/upnp_tv_ctrlpt”. Note : the sample device won’t be built if –disable-device has been configured, and the sample control point won’t be build if –disable-client has been configured.

To run the sample device, you need the “$(LIBUPNP)/upnp/sample/tvdevice/web” sub-directory. Example :

% cd $(LIBUPNP)/upnp/sample/tvdevice % ../../upnp_tv_device

SOLARIS BUILD

The building process for the Solaris operating system is similar to the one described above. Only the call to ./configure has to be done using an additional parameter:

./configure CFLAGS=”-mcpu=<cputype> -mtune=<cputype> -DSPARC_SOLARIS”

where <cputype> has to be replaced by the appropriate CPU tuning flag (e.g. “supersparc”). Afterwards

make make install

can be called as described above.

WINDOWS BUILD

In order to build libupnp under Windows the pthreads-w32 package is required. You can download a self-extracting ZIP file from the following location:

ftp://sources.redhat.com/pub/pthreads-win32/pthreads-w32-2-7-0-release.exe

Execute the self-extracting archive and copy the Pre-build.2 folder to the top level source folder. Rename Pre-build.2 to pthreads. Open the provided workspace build\libupnp.dsw with Visual C++ 6.0 and select Build->Build libupnp.dll (F7)

For building a static library instead of a DLL and for using the static pthreads-w32 library following switches need to be defined additionally:

UPNP_STATIC_LIB - for creating a statically linkable UPnP-library PTW32_STATIC_LIB - for using the static pthreads32 library

  1. Install/Uninstall Instructions

Install

The top-level makefile for the UPnP SDK contains rules to install the necessary components. To install the SDK, as root:

make install

Uninstall

Likewise, the top-level makefile contains an uninstall rule, reversing the steps in the install:

make uninstall

  1. Product Release Notes

The SDK for UPnP Devices v1.2.1a has these known issues:

  • The UPnP library may not work with older versions of gcc and libstdc++, causing a segmentation fault when the library loads. It is recommended that gcc version 2.9 or later be used in building library.
  • The UPnP library does not work the glibc 2.1.92-14 that ships with Red Hat 7.0. For the library to function, you must updated the glibc and glibc-devel packages to 2.1.94-3 or later. There is some issue with libpthreads that has been resolved in the 2.1.94 version.
