INSTALL-MAC.txt

In order to compile the samples in the SDK you need the following:

1. CUDA Toolkit. Supported versions are listed in the release notes.  You should
    also install the latest driver module available after installing the toolkit).

2. CMake 3.0 minimum (http://www.cmake.org/cmake/resources/software.html).  You
   can use the one in MacPorts or the installation from the CMake website.  The
   CMake website version also includes a graphical interface to CMake that is
   identical to the one found in the Windows version.
   
3. C++ compiler.  We have tested gcc and clang on Mac OS X 10.9 with Xcode 6.2.

To compile:

Instructions for building.
1. Create a build directory other than the SDK/ directory.  Using a separate
   build directory allows multiple builds, differing in flavor, platform, etc.
   The build directory will need to be writable, so  try to pick one outside of
   the /Developer section of your hard drive.

2. cd to new directory.
3. Run
     $ ccmake <path>
     or
     $ env CFLAGS=-m64 CXXFLAGS=-m64 ccmake <path>.
   where path is the path to the OptiX SDK/ directory.  This will bring up the
   cmake interface.  Alternatively, to run cmake in non-GUI mode and
   automatically create makefiles with the default options run 'cmake <path>'
   and skip to step 8.
4. Press 'c' within ccmake to begin configure process.
5. Adjust any options, such as build flavor, by moving cursor to field and
   hitting <enter>, changing value, and hitting <enter> again.  One field you
   may want to change is CMAKE_BUILD_TYPE to select a
   Debug build (it defaults to Release which is an optimized build).
6. Press 'c' again to finish configure.
7. Press 'g' to generate Makefiles and exit.
8. Run
     $ make
   to build. Or if you wish to compile a specific sample run
     $ make <sample>  (e.g. 'make cook')
   To see a complete list of targets to compile run
     $ make help
9. Executables should be found in the <build_dir>/bin directory.  All samples
   will be deposited in this same directory.
