Flib v1.1

Classes for managing windows and creating OpenGL contexts (for Windows and Linux) Automatic OpenGL functions loading Wrapper classes for OpenGL objects (Texture, FrameBuffer, Shader etc) Template classes (Vectors, Matrices, Polar vectors, Delegates)

Compilation

The library requires OpenGL development library to compile On Linux systems this means you need glx development library (e.g. from mesa-common-dev)
Executing make in the src folder compiles the library. Building only the static or dynamic linkage can be done using make dynamic and make static.
To compile the tests call make all in the test folder.

Requirements: The library core requires only OpenGL 3.0 to work. OpenGL 4.4 preferred for more efficient implementations. Some tests use compute shaders and therefore require OpenGL 4.3. Tested all tests on Windows and Linux X11.

Troubleshooting

When compiling on Linux systems the following errors may arise

Symptom	Cause	Solution	Command
GL/glx.h not found	glx not installed	Install glx	sudo apt-get install mesa-common-dev
libGL.so not found	OpenGL not updated	Install/Update OpenGL	sudo apt-get install libgl1-mesa-dev or/then sudo ldconfig

Please note that the actual command may differ on your system, refer to your distribution's forum how to install the required development libraries
