Requirements

WinFIG on Windows

WinFIG 3.x or older

Windows 95 or higher. Windows 95 was not tested. Some users reported it works, while others had problems..

WinFIG 5.x

Windows 2000 or higher. It may work on older systems, but I never tested.

WinFIG 6.x

Windows XP, Windows 7, 8 and 10. Windows XP support will be dropped in the future.

All

Exporting to PDF or bitmap formats (PNG, JPEG etc.) requires a GhostScript installation. See the “Links” page for where to get GhostScript. GIF requires ppmquant, which you can get as part of the netpbm package. See the “Links” page too.
For preview of LaTeX formatted texts you need a TeX installation. I tested with MiKTeX 2.7. You also need GhostScript.
For preview of EPS objects you need a GhostScript installation. I tested with AFPL ghostscript version 8.53 and GPL GhostScript 8.64

WinFIG on Linux

I developed and tested on Ubuntu Linux 16.0.4 (xenial). Other systems may require manually installing the Qt libraries. WinFIG probably runs on other versions too if the following is requirements are met:

- - WinFIG depends on Qt libraries version 5 or higher. In case Qt is not installed or not current enough, use your package manager or the shell to install the following packages:
    Ubuntu 20
```
sudo apt-get install qt5-default
sudo apt-get install libqt5qml5
```
    Ubuntu 22
```
sudo apt-get install qtbase5-dev
sudo apt-get install libqt5qml
```
  - For preview of LaTeX formatted texts you need a TeX installation. I tested with TexLive. For a minimum installation use the following:
```
sudo apt-get install texlive-base
sudo apt-get install texlive-latex-base
sudo apt-get install texlive-latex-recommended
sudo apt-get install texlive-fonts-recommended
```

You also need GhostScript for LaTeX preview, for viewing embedding EPS images and for some export formats. GhostScript is employed for several on-the-fly conversions of PostScrtipt data.
For viewing PDF and PS files I use evince:
```
sudo apt-get install evince
```

WinFIG on Mac OS

I developed and tested on Mac OS 10.12 (Sierra). These are the requirements:

For preview of LaTeX formatted texts you need a TeX installation. I tested with MacTeX from tug.org (which is actually TeX Live plus additions). Make sure that /Library/TeX/texbin is part of the “Additional PATH” that you can configure in WinFIGs preferences in the “Environment” tab. If you chose to install the smaller version (BasicTeX), make sure to install the recommended fonts by running the TeX Live update manager this from the shell:
```
tlmgr update --self
tlmgr install collection-fontsrecommended
```
You also need GhostScript for LaTeX preview as well as for exporting to PDF and bitmap formats. It may already be on your computer as part of a full MacTeX installation. It’s not part of BasicTeX. I found a binary distribution that worked for me at Richard Koch’s web site. Another source is tug.org
This point applies only to versions prior to 6.0 beta 1: WinFIG 5.0 depends on Qt libraries version 5.3.1. Right now there is no immediate way for installing them on a Mac. You have to first install the “command line tools for Xcode” from developer.apple.com. Then you can download “Qt 5.3.1” for Mac from qt-project.org/downloads.The Qt installer asks for the desired destination folder. I recommend you install into /Applications/Qt5.3.1, because that’s where WinFIG assumes the Qt libraries. You can choose a different location, but then you probably have to create a symbolic link or WinFIG will report something like "dyld: Library not loaded: /Applications/Qt5.3.1/.../QtWidgetsThe Qt installation folder contains a maintenance tool shat should be used to cleanly uninstall previous versions.
