ALVAR - A Library for Virtual and Augmented Reality

This is a GCC 5.0 Competible source of ALVAR. Built and Tested on Ubuntu 16.04 system.

Compiling on Linux

These instructions were tested on Ubuntu 16.04. You can find the original instructions on building ALVAR on other platforms in doc directory.

1. Setup a build environment. apt-get install build-essential cmake

2. Download and install OpenCV 2.4.0.

3. Install GLUT using distribution package or compile it yourself. sudo apt-get install freeglut3-dev

4. Optionally install OpenSceneGraph using distribution package or compile it yourself. apt-get install libopenscenegraph-dev

5. Run ./build/generate_[target].sh, where target is one of the following supported platforms.

   • gcc43: GNU Compiler Collection 4.3
   • gcc44: GNU Compiler Collection 4.4
   • gcc45: GNU Compiler Collection 4.5 (experimental)
   • gcc5: GNU Compiler Collection 5.0 (experimental)

   Example: cd ./build chmod +x generate*.sh ./generate_gcc5.sh

6. If CMake cannot find the required libraries, the cmakegui is launched. Configure the following variables accroding to your development environment. OpenCV_ROOT_DIR = /path/to/opencv GLUT_ROOT_PATH = /usr OSG_ROOT_DIR = /usr

   Press 'Configure' and modify the paths until the 'Generate' button is enabled. Press 'Generate' and close the cmakegui window.

7. Build the project. cd ./build/build_gcc5_release make

8. Optionally build the 'install' project to copy the sample and demo applications to the ./bin directory. make install

How to compile the ALVAR library SRC package

When building from the source package, you have the option of using the precompiled version of OpenCV provided by the OpenCV development team. The CMake build system should be able to correctly find the dependencies if you specify the OpenCV_ROOT_DIR variable. http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.0

The build instruction are basically the same as when building from the SDK package.

The source package also contains 'master', 'build' and 'package' scripts in the build directory. These are used to generate the SDK and BIN packages.
