C++11 Demos

Overview

This directory contains C++ sample programs for various Ice components; they all use the Ice C++11 mapping. These examples are provided to get you started on using a particular Ice feature or coding technique.

Most of the subdirectories here correspond directly to Ice components, such as IceGrid, Glacier2, and so on. We've also included the following additional subdirectories:

  • Manual contains complete examples for some of the code snippets in the Ice manual.

  • Chat contains the C++ server, and two command-line clients for the ZeroC Chat Demo.

Building and Running the Demos on Linux and macOS

Prerequisites

The makefiles require GNU make 3.80 or later.

On macOS, the command-line demos require the Xcode Command Line Tools to be installed (use xcode-select --install to install them). The Xcode sample program for iOS require the Ice Builder for Xcode.

If you've installed Ice in a non-standard location, you'll need to set the ICE_HOME environment variable with the path name of the installation directory:

export ICE_HOME=~/testing/ice

Building the Demos

Review the settings in make/Make.rules. For example, set OPTIMIZE=yes to build with optimization.

When you're ready to start the build, run make, for example:

make V=1

V=1 in the example above turns on verbose output.

The clean and distclean targets allow you clean all the demos. clean removes the binary files created by the build; distclean removes all these files plus the C++ files generated by slice2cpp.

You can also build or clean a single demo with make <demo-path>[_clean|_distclean], for example:

make V=1 Ice/hello
make Ice/hello_distclean

To build the Xcode iOS example, open C++11 demos (iOS).xcworkspace in Xcode.

Running the Demos

Before running a demo, make sure you've configured your environment to use Ice as described in the release notes.

Refer to the README.md file in each demo directory for usage instructions.

Building and Running the Demos on Windows

Prerequisites

The projects for the sample programs require the Ice Builder for Visual Studio. Add this extension to Visual Studio before opening the solution.

Building the Demos

Building the demos using NuGet packages:

Open the solution file C++11 demos.sln to build the sample programs.

The demos are configured to use Ice C++ binary distribution, packaged with Nuget. The build downloads automatically the Ice Nuget package.

If you have disabled the automatic download of Nuget packages by Visual Studio, you need to restore the packages before you build using Tools > Options > NuGet Package Manager > Manage NuGet Packages for Solution... in Visual Studio.

Then select your target configuration (Debug or Release) and platform (Win32 or x64). Right click on the desired demo in the Solution Explorer window and select Build.

Building the demos without using NuGet packages:

  • Build from command line:

    • Open a Visual Studio command prompt

          cd ice-demos\cpp11
    MSBuild /p:ICE_SRC_DIST=all /p:IceHome=<Ice dist path> "C++11 demos.sln"

  • Build from Visual Studio

    • Open a Visual Studio command prompt

          set ICE_SRC_DIST=all
    devenv

    • When Visual Studio starts set IceHome in the Ice Builder options Tools > Options > Projects and Solutions > Ice Builder

    • Disable automatic restoring of NuGet packages in Visual Studio "Tools > Options > NuGet Package Manager"

    • Select your target configuration (Debug or Release) and platform (Win32 or x64). Right click on the desired demo in the Solution Explorer window and select Build.

Running the Demos

Before running a demo, make sure you've configured your environment to use Ice as described in the release notes.

Refer to the README.md file in each demo directory for usage instructions.

Building the Demo Apps for Universal Windows Platform (UWP)

Prerequisites

The projects for the sample programs require the Ice Builder for Visual Studio. Add this extension to Visual Studio before opening the solution.

UWP requires Windows 10 with Visual Studio 2015.

Building the Demos

Building the demos using NuGet packages:

Open the solution file C++11 demos (Universal Windows).sln.

If you have disabled the automatic download of Nuget packages by Visual Studio, you need to restore the packages before you build using Tools > Options > NuGet Package Manager > Manage NuGet Packages for Solution... in Visual Studio.

Then select your target configuration (Debug or Release), and platform (Win32, x64 or ARM). Right click on the desired demo in the Solution Explorer window and select Build.

Building the demos without using NuGet packages:

  • Build from command line:

    • Open a Visual Studio command prompt

          cd ice-demos\cpp11
    MSBuild /p:ICE_SRC_DIST=all /p:IceHome:<Ice dist path> "C++11 demos (Universal Windows).sln"

  • Build from Visual Studio

    • Open a Visual Studio command prompt

          set ICE_SRC_DIST=all
    devenv

    • When Visual Studio starts set IceHome in the Ice Builder options Tools > Options > Projects and Solutions > Ice Builder

    • Disable automatic restoring of NuGet packages in Visual Studio "Tools > Options > NuGet Package Manager"

    • Select your target configuration (Debug or Release) and platform (Win32, x64 or ARM). Right click on the desired demo in the Solution Explorer window and select Build.
