To install FreeFem++ on your mac you need to run (double click on) the shell script Install-MacOS.command (you will need to type your password and you must be "administrator" of your machine). This script installs FreeFem++, ffglut, ffmedit in /usr/local/bin , as well as some possibly missing libraries and the FreeFem.app in /Applications. This version can be used in 3 modes - Like a Mac application with drap and drop, etc; then it opens a terminal window for the console IO and (when needed) a graphic window which accepts keyboard commands when in wait mode (listed by typing a "?"). - In terminal mode: (only when FreeFem++.app has not been moved out of the/ Applications directory). In the terminal window one must type "FreeFem++ " where is the name of your xxx.edp file. - With the latest version of the smultron.app (http://tuppis.com/smultron/) text editor directly from inside the editor by typing "cmd+r". Smultron recognizes xx.edp files and activates a color highlight of the keywords (don't forget a "cmd+s" before the "cmd+r"). Technical Note: ------------- This will not work on MacOs systems less than 10.3. This version uses OpenGL/GLUT graphics. The installer command puts in /usr/local/bin the following binaries: ff-c++ tools to compile dynamic libray with freefem++ FreeFem++ the freefem++ command ffglut the graphic visalisator ffmedit the medit sofware Some external library are in the archive file OtherMacOsLib.tgz; you may need to install these READ le READ_MAC to buil freefem++ on your mac.
