The current release is 1.3.6p2. The POCO C++ Libraries are open source software, released under the Boost Software License.

Please see the included README file for instructions.

On Unix platforms, you'll be fine with ./configure; make.
For Windows users, Visual C++ project files and build scripts are included.

You can exclude some libraries from the build.

On Windows, edit the file named components and remove the lines corresponding to the libraries you wish to exclude.
On Linux, call the configure script with the --omit option, e.g.
./configure --omit=NetSSL_OpenSSL,Crypto or ./configure --omit=Data.

OpenSSL: Most Unix systems already have OpenSSL preinstalled. If your system does not have OpenSSL, please get it from the OpenSSL website or another source. You do not have to build OpenSSL yourself — a binary distribution is fine.

The easiest way to install OpenSSL on Windows is to use a binary (prebuild) release, for example the installer from Shining Light Productions.
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.

ODBC: The Data library requires ODBC for the ODBC connector.
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.

MySQL Client: For the MySQL connector, the MySQL client libraries and header files are required.
