Welcome to the vgl wiki! Here you will find help on building and using VGL. VGL is the Open Source (BSD license) library from Kitware and NYU-Poly.
Download the data first from here: https://github.com/OpenGeoscience/geoweb-data.git
git clone https://github.com/OpenGeoscience/geoweb-data.git
VGL source has minimum dependencies but testing requires additional libraries and datasets. In order to build VGL on your system, follow the steps below:
git clone https://github.com/OpenGeoscience/vgl.git vgl-src mkdir vgl-build
cd vgl-build
cmake -DBUILD_TESTING:BOOL=ON ../vgl-src
ccmake .
Now set VGL_DATA_DIR to path_to_geoweb-data/documents
make
Now you should be set to run the tests. Start the python http sever
cd deploy (default deploy directory if you have not changed it)
python -m SimpleHTTPServer
Now visit http://localhost:8000/testing/drawCountries.html

VGL uses selenium, numpy, matplotlib, firefox, and ctest for testing. You can install most of the dependencies using pip as shown below:
pip install selenium
pip install numpy
pip install matplotlib
Depending on your OS and system, you may have to install libpng, libpng-dev etc. Once installed, you can
turn ON testing by setting BUILD_TESTING to ON in ccmake or cmake-gui. Configure, generate,
and build as usual and then run
cd path_to_build_dir
ctest
The output should looks something like this (may vary on Windows or Mac)
38: Problem opening file 38: no baseline image yet 38: Check in drawCountries-2013-10-14 18:04:45.226486.png as a new baseline 38: -1 1/1 Test #38: python-drawCountriesReg.py ....... Passed 8.12 sec
The following tests passed: python-drawCountriesReg.py
100% tests passed, 0 tests failed out of 1
