Apache Ignite C++ Examples
==================================

Common requirements
----------------------------------
 * Java Development Kit (JDK) must be installed: https://java.com/en/download/index.jsp
 * JAVA_HOME environment variable must be set pointing to Java installation directory.
 * IGNITE_HOME environment variable must be set to Ignite installation directory.
 * Ignite must be built and packaged using Maven. You can use the following Maven command: ./mvnw clean package -DskipTests
 * Apache Ignite C++ must be built according to instructions for your platform. Refer to
   $IGNITE_HOME/platforms/cpp/DEVNOTES.txt for instructions.
 * For odbc-example additionally ODBC Driver Manager must be present and installed on your platform and
   Apache Ignite ODBC driver must be built and installed according to instructions for your platform. Refer to
   $IGNITE_HOME/platforms/cpp/DEVNOTES.txt for build instructions and to $IGNITE_HOME/platforms/cpp/odbc/README.txt.
   for installation instructions.

Running examples.
----------------------------------

Prerequisites:
 * C++ compiler and SDK:
  Linux and Mac OS X:
   * clang >= 3.9 or gcc >= 3.6
  Windows:
   * Visual Studio 2010 or later
   * Windows SDK 7.1 or later
 * CMake >= 3.6 must be installed
 * IMPORTANT: Apache Ignite C++ should be installed. Refer to $IGNITE_HOME/platforms/cpp/DEVNOTES.txt for instructions.

To build examples execute the following commands one by one:
 * cd $IGNITE_HOME/platforms/cpp/examples
 * mkdir cmake-build-[debug|release]
 * cd ./cmake-build-[debug|release]
 * run CMake configuration:
  * on Linux or Mac OS X:
     cmake .. -DCMAKE_BUILD_TYPE=[Release|Debug] [-DIGNITE_CPP_DIR=<ignite_install_dir>]
  * on Windows:
     cmake .. -DCMAKE_GENERATOR_PLATFORM=[Win32|x64] -DIGNITE_CPP_DIR=<ignite_install_dir>

    IMPORTANT: Ignite C++ should be built and installed for this command to work correctly. If you have installed
    Ignite C++ in non-default directory or getting "IGNITE_INCLUDE_DIR-NOTFOUND" errors while executing this command,
    you should make sure you've set IGNITE_CPP_DIR option correctly, pointing to the installation directory of
    Ignite C++ (it should be the same path that was used in CMAKE_INSTALL_PREFIX during Ignite C++ installation)

 * cmake --build . --config [Release|Debug]

CMake by default generate on Windows Visual Studio projects. You can find generated projects in CMake
build directory (./cmake-build-[release|debug]) and open examples.sln in Visual Studio.

If Apache Ignite C++ is installed in default directories (i.e. /usr/local or /usr), setting IGNITE_CPP_DIR property
is not necessary. As a result executables will be in corresponding subdirectories in cmake-build-release directory.

Running examples.
----------------------------------

Before running examples ensure that:
 * Ignite library binaries (<ignite_install_dir>/bin or <ignite_install_dir>/lib) are added to $PATH
   (Windows and Linux) or $LD_LIBRARY_PATH (Linux only). This is especially important for Windows, as in Linux systems
   installation path is ordinary pointed by $PATH by default;
 * $JAVA_HOME is set to point to a valid JDK installation;
 * $PATH or $LD_LIBRARY_PATH environment variables are set and pointing to a directory with libjvm library. In Linux
   this  library is usually located in $JAVA_HOME/jre/lib/amd64/server directory, while in Windows it is most probably
   in $JAVA_HOME/jre/bin/amd64/server;
 * For odbc-example additionally ODBC Driver Manager must be present and installed on your platform. This is concerns
   Linux systems as Windows always have system ODBC Driver Manager present by default;
 * For odbc-example Ignite ODBC driver must be built and installed according to instructions for your platform.

Importing CMake projects to Visual Studio (tm) (since 2015):
------------------------------------------------------------
 Use CMakeSettings.json.in files in examples root directory as a template of real CMakeSettings.json.
 Edit it manually to set up correct environment variables and import CMake projects as usual.
