VES/Developers Guide (Windows)

Installation steps

This page explains the VES and Kiwi installation process using Microsoft Visual C++ (the compiler for the host code compilation, and the NMake tool to compile the whole bundle) under Windows, targeting the Android platform.

Getting Started

For quick instructions, see the Download & Build Instructions page. This developer's guide will go into more detail than is found on that page.

Prerequisites

• Android NDK r8c

• Android SDK

Important: You need to add the subdirectories of Android SDK "platform-tools" and "tools" to your PATH environment variable.

Checkout the source from Git

Using TortoiseGIT, clone the repository:

git://vtk.org/VES.git using TortoiseGIT 

Using Git to checkout the VES source code with the command line:

> git clone git://vtk.org/VES.git

See the VES Git table of contents page for details on the Git repository and development workflow.

Setting up your development environment

Android

You must have the Android SDK and Android NDK installed. To get started with Android development, visit the Android Developer's Guide. It is recommended that you build and run some of the Android sample applications that are provided with the Android SDK to get familiar with running code on your device before attempting to build and run VES/Kiwi based applications. See this README in the VES repository for a guide to setting up the Android development environment.

Build with CMake

CMake is used to configure and build VES.

What is a Superbuild?

VES is normally built using a superbuild. A superbuild manages the download, configure, build, and install steps of multiple projects all at once. The VES superbuild will download vtkmodular, then configure and build both vtkmodular and VES using the appropriate cross compiler for the target architecture. The target architecture may be an android device, iOS device, or the iOS simulator on x86. When configuring vtkmodular and ves, cmake is invoked in cross compile mode using a toolchain file for the target architecture. The toolchain files are located in the CMake/toolchains directory.

Building

Android instructions

The Android NDK r8c is currently the required version. It can be downloaded from:

http://dl.google.com/android/ndk/android-ndk-r8c-windows.zip

The following commands will compile vtk and ves libraries for Android:

Edit Apps/Android/CMakeBuild/configure.bat and set the variable ANDROID_NDK to your NDK installation path. You may also change the build type to Debug while the default is Release.

Start a VisualStudio command prompt. Then to the VES directory and type:

> cd Apps/Android/CMakeBuild
> configure.bat
> cd build
> nmake 

The superbuild compilation process starts.

Next, build and run the KiwiViewer application. Ant version 1.8 or higher is required.

> cd Apps/Android/Kiwi
>
> REM - if android, adb, ant, or cmake are not in your PATH, edit tools.bat to enter the correct paths
>
> configure_cmake.bat
> configure_ant.bat
> compile.bat

Use adb to confirm that your device is listed:

$ adb devices

Run KiwiViewer on the device:

$ run.bat

FAQ

Issue

The download of Eigen fails. This is because CMake may not support HTTPS protocol (through an URL redirection) used to fetch the Eigen archive.

Solution

In file CMake/ves-superbuild.cmake, change the line:

 set(eigen_url http://bitbucket.org/eigen/eigen/get/3.1.2.tar.gz)
