Freeglut on MacOS X
|
|
===================
|
|
|
|
Currently freeglut does not support the native Cocoa API and the OpenGL
|
|
framework which works with it, but rather relies on X11 (XQuartz) and the Mesa
|
|
OpenGL and GLX libraries.
|
|
|
|
The simplest way to set up the prerequisites for building and using freeglut is
|
|
with the homebrew package management system: https://brew.sh
|
|
|
|
Build instructions
|
|
------------------
|
|
|
|
Prerequisites:
|
|
- If you don't already have homebrew, go to https://brew.sh and follow their
|
|
instructions.
|
|
- If you don't already have a compiler toolchain installed, download the Xcode
|
|
commandline tools from the apple store and install them first.
|
|
- If you don't have XQuartz installed, get it from https://www.xquartz.org
|
|
- Use homebrew to install cmake, and all the necessary libraries:
|
|
`brew install cmake libx11 libxi libxrandr libxxf86vm pkg-config mesa`
|
|
|
|
Build freeglut:
|
|
- Create a build directory under the freeglut directory and change into it:
|
|
`mkdir build && cd build`
|
|
- Run cmake to generate the makefile:
|
|
`cmake -DFREEGLUT_BUILD_DEMOS=OFF -DOPENGL_gl_LIBRARY=/usr/local/lib/libGL.dylib ..`
|
|
- Run `make` to build freeglut, and `make install` to install it.
|
|
|
|
Usage
|
|
-----
|
|
|
|
To use freeglut in your program **do not** include `<GLUT/glut.h>`; that header
|
|
is part of Apple's GLUT framework. Use `#include <GL/glut.h>` instead as usual,
|
|
or `#include <GL/freeglut.h>` if you wish to take advantage of the extended
|
|
freeglut API.
|
|
|
|
Similarly, to link with freeglut **do not** use `-framework GLUT` in your
|
|
linker command line. Instead use the standard `-lglut` argument, as you would
|
|
on any other UNIX system.
|
|
|
|
Known issues
|
|
------------
|
|
|
|
Some versions of XQuartz do not map the option keys to ALT by default, making
|
|
it impossible to get the `GLUT_ACTIVE_ALT` bit set in the bitmask returned by
|
|
`glutGetModifiers`. To change this behavior go to the XQuartz preferences and
|
|
enable the "Option keys send Alt_L and Alt_R" checkbox in the "input" tab.
