You may install directly from the SR Research website (you will need a login), see instructions below or if you are a GRU member you can download the files directly following the instructions below (note that the libraries are SR Research proprietary so we cannot distribute them to non-lab members).

1. Download the following: edfapi Universal eyelink_core_x64_osx_beta.tar.
2. Double-click on the .tar files to open them (or from a terminal use tar xfv *.tar).
3. Copy the Frameworks edfapi.framework and eyelink_core.framework from the downloaded files above into your directory /Library/Frameworks.
4. Finally, you can compile with mglMake('eyelink') in matlab (If you already have *.mexmaci64 under your mgl/mgllib/mglEyelink, you may need to delete them prior to the compilation).

As of 07/05/2011, the installation procedure is not straight forward. First, you need create your account at SR research support pag. Then download an installer and two additional files from here(1,2 and 3 in the next picture).
