README

This is the README file for the POCO C++ Libraries.

In this document you will find a brief description of the directory layout,
as well as a description necessary steps to build the POCO C++ Libraries.

The Foundation library contains a platform abstraction layer (including classes
for multithreading, file system access, logging, etc.), as well as
a large number of useful utility classes, such various stream buffer and stream
classes, URI handling, and many more.
The XML library contains an XML parser with SAX2 and DOM interfaces,
as well as an XMLWriter.
The Util library contains classes for working with configuration files and 
command line arguments, as well as various utility classes.
The Net library contains network classes (sockets, HTTP client/server, etc.).
All libraries come with a test suite and a number of sample programs.

The basic directory layout is as follows:

build/                     the build system for Unix and additional utility scripts
    config/                build configurations for various Unix platforms
    rules/                 common build rules for all platforms
    scripts/               build and utility scripts
    vxconfig/              VxWorks build configurations

bin/                       all executables (dynamic link libraries on Windows)
bin64/                     all 64-bit executables (and DLLs)

doc/                       additional documentation

lib/                       all libraries (import libraries on Windows)

Depending on what package you have downloaded, there may be other libraries
as well (such as Data, Crypto, NetSSL_OpenSSL and Zip).


DOCUMENTATION
=============

Plenty of documentation (tutorial slides, articles and SDK reference)
is available at <http://pocoproject.org/documentation/>.


EXTERNAL DEPENDENCIES
=====================

The following libraries require third-party software (header files and
libraries) being installed to build properly:

- NetSSL_OpenSSL and Crypt require OpenSSL.
- Data/ODBC requires ODBC 
  (Microsoft ODBC on Windows, unixODBC or iODBC on Unix/Linux)
- Data/MySQL requires the MySQL client.

Most Unix/Linux systems already have OpenSSL preinstalled. If your system 
does not have OpenSSL, please get it from <http://www.openssl.org> or 
another source. You do not have to build OpenSSL yourself - a binary 
distribution is fine (e.g., apt-get install openssl libssl-dev).

The easiest way to install OpenSSL on Windows is to use a binary 
(prebuild) release, for example the one from Shining Light 
Productions that comes with a Windows installer
<http://www.slproweb.com/products/Win32OpenSSL.html>. 
Depending on where you have installed the OpenSSL libraries, 
you might have to edit the build script (buildwin.cmd), or add the 
necessary paths to the INCLUDE and LIB environment variables.

The Data library requires ODBC support on your system if you want 
to build the ODBC connector (which is the default). On Windows 
platforms, ODBC should be readily available if you have the 
Windows SDK. On Unix/Linux platforms, you can use iODBC 
(preinstalled on Mac OS X) or unixODBC. For the MySQL connector, 
the MySQL client libraries and header files are required.

The Data/ODBC and Data/MySQL Makefiles will search for the ODBC 
and MySQL headers and libraries in various places. Nevertheless, 
the Makefiles may not be able to find the headers and libraries. 
In this case, please edit the Makefile in Data/ODBC and/or Data/MySQL 
accordingly.


BUILDING ON WINDOWS
===================

Microsoft Visual Studio 7.1 (2003), 8.0 (2005), 9.0 (2008), 10.0 (2010) or 11.0 (2012) 
is required to build the POCO C++ Libraries on Windows platforms. Solution and project 
files for all versions are included. For Visual Studio 2008 and later, 64-bit (x64) builds 
are supported as well.
You can either build from within Visual Studio (Build->Batch Build->Select All;Rebuild)
or from the command line. To build from the command line, start the
Visual Studio .NET 2003 (or 2005/2008/2010/2012) Command Prompt and cd to the directory 
where you have extracted the POCO C++ Libraries sources. Then, simply start the buildwin.cmd 
script and pass as argument the version of visual studio (71, 80, 90, 100 or 110). You can 
customize what is being built by buildwin.cmd by passing appropriate command line arguments 
to it. Call buildwin.cmd without arguments to see what is available.

To disable certain components (e.g., NetSSL_OpenSSL or Data/MySQL) from the build,
edit the file named "components" and remove the respective lines.

Certain libraries, like NetSSL_OpenSSL, Crypto or Data/MySQL have dependencies
to other libraries. Since the build script does not know where to find the necessary
header files and import libraries, you have to either add the header file paths to
the INCLUDE environment variable and the library path to the LIB environment variable,
or you'll have to edit the buildwin.cmd script, where these environment variables can
be set as well. 

In order to run the test suite and the samples, the top-most bin directory containing
the shared libraries must be in the PATH environment variable.

IMPORTANT NOTE: Please make sure that the path to the directory containing the
POCO C++ Libraries source tree does not contain spaces. Otherwise, the Microsoft
message compiler may fail when building the Foundation library.


BUILDING FOR WINDOWS CE

Building for Windows CE is supported with Microsoft Visual Studio 2008.
Unless you have the Digi JumpStart Windows CE 6.0 SDK installed, you'll
have to modify the included Visual Studio project and solution files.
Please see the SDK Reference Documentation <http://pocoproject.org/documentation>
for instructions.


BUILDING ON UNIX/LINUX/MAC OS X
===============================

For building on Unix platforms, the POCO C++ Libraries come with their own
build system. The build system is based on GNU Make 3.80 (or newer), with the help 
from a few shell scripts. If you do not have GNU Make 3.80 (or later) installed on 
your machine, you will need to download it from <http://directory.fsf.org/wiki/Make>, 
build and install it prior to building the POCO C++ Libraries.

You can check the version of GNU Make installed on your system with

> gmake --version

or

> make --version

Once you have GNU Make up and running, the rest is quite simple.
To extract the sources and build all libraries, testsuites and samples, simply

> gunzip poco-X.Y.tar.gz
> tar -xf poco-X.Y.tar
> cd poco-X.Y
> ./configure
> gmake -s

See the configure script source for a list of possible options.
For starters, we recommend --no-tests and --no-samples, to reduce build times.
On a multicore or multiprocessor machine, use parallel makes to speed up
the build (make -j4).

Once you have successfully built POCO, you can install it
to /usr/local (or another directory specified as parameter
to configure --prefix=<path>):

> sudo gmake -s install

You can omit certain components from the build. For example, you might
want to omit Data/ODBC or Data/MySQL if you do not have the corresponding
third-party libraries (iodbc or unixodbc, mysqlclient) installed
on your system. To do this, use the --omit argument to configure:

> ./configure --omit=Data/ODBC,Data/MySQL


To build on Mac OS X 10.3 with GCC 3, do the following:
(NOTE: This only affects 10.3; for 10.4 or newer see above)

> ./configure --config=Darwin7
> make -s


IMPORTANT: Make sure that the path to the build directory does not
contain symbolic links. Furthermore, on Mac OS X (or other systems
with case insensitive filesystems), make sure that the characters in 
the path have the correct case. Otherwise you'll get an error saying
"Current working directory not under $PROJECT_BASE.".


BUILDING ON QNX NEUTRINO
========================

For QNX Neutrino, the Unix build system (see the instructions above) is used.
You can use the build system to cross-compile for a target platform on a Solaris or
Linux host. Unfortunately, the Cygwin-based Windows host environment has some major
quirks that prevent the build system from working there. You can also use the
build system on a self-hosted QNX system. The default build configuration for QNX
(found in build/config/QNX) is for a self-hosted x86 platform. To specify another
target, edit the CCVER setting in the build configuration file. For example, to
compile for a PowerPC target, specify CCVER=3.3.1,gcc_ntoppcbe.

Service Pack 1 for QNX Neutrino 6.3 must be installed, otherwise compiling the
Foundation library will fail due to a problem with the <list> header in the
default (Dinkumware) C++ standard library.

When building on QNX, you might want to disable NetSSL_OpenSSL, Crypto and
some Data connectors, unless you have the necessary third party components
available:

> ./configure --omit=NetSSL_OpenSSL,Crypto,Data/ODBC,Data/MySQL


BUILDING FOR VXWORKS
====================

Please see the VxWorks Platform Notes in the Reference Documentation for
more information. The Reference Documentation can be found online
at <http://pocoproject.org/docs/>.
