Before installing something on a Mac, make sure things aren't already installed by some other user by checking the appropriate commands in the terminal (gcc –version and cmake –version).

MacOS Versions are:

• MacOS X 10.5 Leopard
• MacOS X 10.6 Snow Leopard
• MacOS X 10.7 Lion
• MacOS X 10.8 Mountain Lion
• MacOS X 10.9 Mavericks -> goto GCC on MacOS X 10.9 Mavericks .

You can obtain your version by clicking on the apple in the left upper corner -> "about this mac". The terminal is located in Programs -> utilities (Dienstprogramme) -> Terminal.

Installation of UG4

Please follow the description at https://github.com/UG4/ughub to obtain a copy of ug4. Below you'll find hints on how to obtain additional software which is required to build ug4.

---

CMake

---

• Download CMake: Download the CMake 2.8.12 dmg-file (see also here. (! minimum version 2.8.10 !)
• Install CMake on your computer. Install the command line tools, when requested during installation.
• Open a terminal window. Enter cmake. If you see some output cmake version ... CMake has been installed correctly.

---

GCC on MacOS X 10.9 Mavericks

---

In order to use UG4 with MacOS X 10.9 Commandline Tools should be installed properly. This can be done be entering the following command into Terminal:

xcode-select --install

Note

There have been some problems with old cmake versions and mavericks, especially after upgrading your system. Make sure you have cmake 2.8.12.

---

GCC on MacOS X <= 10.8

---

Easiest way is to use Kenneth Reitz' page on gcc/command line utilities: https://github.com/kennethreitz/osx-gcc-installer/ .

Another way is to use the Apple homepage:

• Create a apple developer ID here (it's free).
• Go to https://developer.apple.com/downloads/index.action, search for "Command Line Tools", pick the appropriate version.
• Install. Now you should have gcc and svn (!) available in the terminal.

Note

XCode, installed through the AppStore, will not provide you with command line utilities.

you can install Macports and upgrade your compilers then.

---

Additional Software

---

Highly recommended:

• SVN : Subversion for the terminal (check in terminal if svn works, otherwise install). http://www.wandisco.com/subversion/download#osx
• OpenMPI : for parallel computing. (check if mpicc is available). Other:
• X11 : Window manager used by some programs, not included in MacOS 10.8. http://xquartz.macosforge.org/
• doxygen : to create this docu locally.
• gnuplot
• ParaView

You can install most of this with uginstall - Scripts for installation.

If you need fortran/gfortran on Mountain Lion: http://web.mit.edu/mfloyd/www/computing/mac/gfortran/, sudo ln -s /usr/bin/gfortran-4.2 /usr/bin/gfortran.
