# Mathematica

Mathematica is a commercial program used in scientific, engineering and mathematical fields. Here we explain how to install it.

## Installation

### Mathematica 6

#### Mounting iso

One way to mount the Mathematica .iso is to create */media/iso* and add the following line to the fstab:

/location/of/mathematica.iso/media/iso iso9660 exec,ro,user,noauto,loop=/dev/loop0 0 0

Now you can mount it with:

mount /media/iso

#### Running the Installer

You can start the installer by navigating to:

/Unix/Installer

Run *MathInstaller* with:

sh ./MathInstaller

**Note:**If you do not place the "sh" in front, then you will get an error about a bad interpreter.

#### Fonts

Add the directories containing Type1 and BDF fonts to your FontPath.

#### Troubleshooting

If you have font rendering problems where certain symbols do not show up (i.e. "/" appears as a square), try uninstalling font-mathematica.

Also, try this solution.

### Mathematica 7

Mathematica 7 is much easier to install.

tar xf Mathematica-7.0.1.tar.gz cd Unix/Installer ./MathInstaller

Follow instructions.

For KDE users, the Mathematica icon may appear in the *Lost & Found* category. To solve this, execute the following as root:

# ln -s /etc/xdg/menus/applications-merged /etc/xdg/menus/kde-applications-merged

### Mathematica 8.0.4.0

On 64-bit machines, two known issues are present; but solutions are provided. The second issue is present on 64-bit installs: but not yet confirmed on a 32-bit arch setup.

The first issue assumes you are trying to use nVidia, CUDA and OpenCL libraries within Mathematica.

The 64-bit archlinux nVidia and opencl driver packages install libraries in `/usr/lib`

, not in `/usr/lib64`

as does nVidia's binary installer. This is not a problem: `/usr/lib`

is the correct location for 64-bit libraries on a 64-bit arch system. However, a 64-bit install of Mathematica will assume the drivers are installed in `/usr/lib64`

; other distributions that Mathematica has been tested on have their drivers in that location. The easiest method to overcome this is to make a symlink from `/usr/lib64`

to `/usr/lib`

. Mathematica will be able to find nVidia, CUDA, and OpenCL libraries this way without further tweaking.

A second, separate but partial solution, is to set the following environment variables:

export NVIDIA_DRIVER_LIBRARY_PATH=/usr/lib/libnvidia-tls.so

export CUDA_LIBRARY_PATH=/usr/lib/libcuda.so

This second method, however, still will not permit Mathematica to find the OpenCL libraries in `/usr/local`

as Mathematica seems hardwired to find them in `/usr/lib64`

.

The second issue with Mathematica 8 in 64-bit archlinux (may also affect 32-bit environments; but not tested) is a reproducible crash when performing WolframAlpha[] functions. By default, Mathematica is configured to detect the system's proxy settings when configuring how to connect to the internet to fetch data. A "bug" exists that will eventually crash Mathematica when the calling library is used. A workaround is to avoid this library call altogether by configuring Mathematica to "directly connect" to the internet. (*Edit > Preferences > Internet Connectivity > Proxy Settings*). This bug has been reported to Wolfram.

### Mathematica 9

Install mathematica^{AUR} from the AUR. The *Mathematica_9.0.1_LINUX.sh* installation script is required.
