GLS — GL Stuff Library

Requirements

GLS is a header-only library. It does not depend on anything other than the standard C++ libraries.

GLS requires a compiler with C++11 support. Not all features are used, however many newer features are used that might not be supported by all compilers even though they claim C++11 support. Your mileage may vary.

In order to build the examples, you will need SFML 2.3 or the gl_dev branch of SFML 2.1. Previous versions do not provide a way of explicitly creating an OpenGL 3.2 core profile context, so minor alterations to the example code have to be made if using an older version of SFML. SFML is available from http://sfml-dev.org/ or GitHub.

The build system in use is CMake. It's available for all major platforms.

Installing

Since GLS is a header-only library, just copy the GLS directory to a location of your choosing and add the include directory to your compiler's search paths. Alternatively, you can generate an installation script through the CMake configuration.

To generate a configuration for the examples and installation, run

cmake .

inside the root directory of GLS. Alternatively just generate a configuration using the CMake GUI. The required entries should be set, and if not, they are well documented so they can be easily filled manually.

After generating the configuration, build the install target.

Using GLS in your own projects

To use GLS, include the necessary headers. The GLS meta-header:

#include <gls.hpp>

IMPORTANT: Make sure to include GLS headers after you include your OpenGL headers. GLS makes use of OpenGL definitions and entry points and will cause your code to fail to compile if it can't find them.

Since GLS is a header-only library, building it is not required before using it. It follows that there are no library files to link as well. Simply make sure that your compiler is able to find GLS's include directory.

If you are using CMake for your project and you've properly installed GLS (see Installing), you can automate the process of finding GLS. First, copy the file cmake/Modules/FindGLS.cmake to your project's CMake Modules directory and make sure CMake knows that it should search in this directory. Then add the following to your project's CMakeLists.txt file:

find_package( GLS REQUIRED )
include_directories( ${GLS_INCLUDE_DIR} )

In case CMake can't find your GLS installation, you can still specify the path manually by setting the GLS_ROOT CMake variable.

Because GLS is a helper library for OpenGL, be sure to link the OpenGL library for your platform to your final application as well.

Documentation

A pre-generated version of the documentation can be found online at: http://binary1248.github.io/GLS

You can also generate the API documentation yourself. Enable the GLS_BUILD_DOC entry in CMake, configure and generate the build configuration. Run the doc target to generate the API documentation from the headers. You will need Doxygen to do this.
