- \section intro_sec Introduction
- libt2n (talk to neighbor) is a C++ library for inter-process communication (IPC, s.a. http://en.wikipedia.org/wiki/Inter-process_communication)
- with an additional code generator to make remote procedure calls simple.
- \par
- XXX: improve this paragraph: The input for the code generator is standard C++ code (in fact we use gccxml to parse the C++ code and the code generator takes the XML as input) and you mark the procedures you want to expose to other processes.
- It then generates the stubs needed.
- The exported procedures can be grouped. For each group the code generator is called and generates 6 output files: group_common.hxx, group_common.cpp, group_client.hxx, group_client.cpp, group_server.hxx, group_server.cpp. The _common files are used by client and server whereas the _client files are used by the client and the _server files by the server only.
- \par
- To simplify the build process a Makefile snippet is provided that allows to create a server program and a client library (including a corresponding .pc file) using the autotools easily.
- \section install_sec Installation
-
- \subsection requirements Requirements
- - boost <http://www.boost.org/> (serialization <http://www.boost.org/libs/serialization/doc/>)
- - gccxml <http://www.gccxml.org>
- - libxmlpp <http://libxmlplusplus.sourceforge.net/>
-
- \subsection recommended Recommended
- - pkg-config <http://pkgconfig.freedesktop.org/wiki/>
- - autotools (automake, autoconf, libtool)
-
- \subsection Compilation
- \verbatim
- ./configure && make install
- \endverbatim
-
-
- \section usage Usage example
-
- In this example we create two packages using the autotools:
- - server program and client library to connect to the server. The server exports a simple procedure using one group: "t2nexample"
- - client program using the library
-
- \subsection server Example server program and client library
-
- \par The procedure to export (input for the code generator - libt2n-codegen): t2nexample.cpp:
- \verbinclude libt2n-example1/t2nexample.cpp
-
- \par Required includes go into the group header file: t2nexample.hxx:
- libt2n uses boost for serialization. This means all types involved in a remote procedure call must be boost serializable. In this example we use std::string and boost
- already provides serialization for std::string in the boost/serialization/string.hpp header file.
- \verbinclude libt2n-example1/t2nexample.hxx
-
- \par The server program:
- \verbinclude libt2n-example1/server.cpp
-
- \par Using autoconf and automake to build a example server program and a client library.
- In the configure.in(.ac) we put a check for libt2n:
- \verbinclude libt2n-example1/configure.in
- Writing the Makefile.am isn't difficult either:
- \verbinclude libt2n-example1/Makefile.am
-
- \par Build and install the package
- \verbatim
- autoreconf -f -i && ./configure && make install
- \endverbatim
-
- \subsection client Client using the library
- Using the library is as simple as using any other library using pkg-config (the pkg-config .pc file is created automatically by the included Makefile snippet)
- \par We only have to check that the library is installed
- \verbinclude libt2n-example1-client/configure.in
- \par The Makefile.am needs nothing special
- \verbinclude libt2n-example1-client/Makefile.am
- \par The client program
- \verbinclude libt2n-example1-client/client.cpp
-
- \par Build and install the package
- \verbatim
- autoreconf -f -i && ./configure && make install
- \endverbatim
-
- \par Test
- \verbatim
-$ cd /tmp
-$ file socket
-socket: cannot open `socket' (No such file or directory)
-$ libt2n-example1-server &
-[1] 7711
-$ file socket
-socket: socket
-$ libt2n-example1-client && echo ok
-ok
-$ kill %1
-$ rm socket
- \endverbatim
