+# Build instructions
+
+## Mac OS X
+
+```
+make
+```
+
+
+## Emscripten
+
+```
+emmake make emscripten
+```
+
+Note that mousewheel support requires a hacked emscripten:
+
+In `src/library_glfw.js`, replace the first part of the mousewheel function with
+
+```js
+      GLFW.wheelPos = (event.detail || -event.deltaY);
+```
+
+In `system/include/GL/glfw.h`, replace the wheel callback typedef with
+
+```c
+typedef void (GLFWCALL * GLFWmousewheelfun)(float);
+```
