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

## Installation

Since Mathematica is a non-free application and upgrades may incur costs, this section lists instructions for different available versions.

### Mathematica 6

#### Mounting iso

One way to mount the Mathematica `.iso` is to create a `/media/iso` mount directory 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.

### 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

An issue with Mathematica 8 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 10

Install mathematicaAUR (need historical version). The `Mathematica_10.XX.YY_LINUX.sh` installation script is required; you will need to download this separately from Wolfram.com, your university, etc. You will also need an activation key.

### Mathematica 11

Install mathematicaAUR. Obtain `Mathematica_11.XX.YY_LINUX.sh` from Wolfram Research, along with an activation key, and save it to the package build directory. Successful install may throw non-critical errors: xdg-icon-resource, mkdir, xdg-desktop-menu. For more details see the mathematica PKGBUILD file.

Mathematica 11 automatically creates a document folder 'Wolfram Mathematica' in $UserDocumentsDirectory, which is set by Mathematica according to XDG user directories.

## Troubleshooting

### Missing symbols

If you have font rendering problems where certain symbols do not show up (i.e. `/` appears as a square), try this solution. It also states the issue is fixed with Mathematica version 9.

Try having applications use anti-aliasing. For KDE: System Settings > Application Appearance > Fonts > Use anti-aliasing (Enabled)

### HiDPI / Retina Screens

If you have a HiDPI screen, such as an Apple Retina display, and the main text in Mathematica looks small when you open it, this can be fixed:

- Go to Edit → Preferences
- From the Advanced tab, click Open Option Inspector
- In the tree on the right, go to Formatting Options → Font Options → Font Properties
- Change the value for "ScreenResolution" to double its current setting, e.g. 72 → 144. You can also use `xdpyinfo | grep resolution` to get a more precise number (which will need to be doubled).

### Conflicts with system libraries

The Mathematica package includes a number of its own libraries, located in `<INSTALL_DIR>/SystemFiles/Libraries/Linux-x86-64`. They may lead to some compatibility issues and fallback to the system versions of some of these libraries may be necessary.

#### Symbol lookup error: /usr/lib/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

Force Mathematica to use the system version of the freetype library.

    # cd <INSTALL_DIR>/SystemFiles/Libraries/Linux-x86-64
    # mv libfreetype.so.6 libfreetype.so.6.old

#### Mathematica/11.3/SystemFiles/Libraries/Linux-x86-64/libz.so.1: version `ZLIB_1.2.9' not found (required by /usr/lib/libpng16.so.16)

Force Mathematica to use the system version of the zlib library.

    # cd <INSTALL_DIR>/SystemFiles/Libraries/Linux-x86-64
    # mv libz.so.1 libz.so.1.old
