Dataplot is currently built from source using the gfortran/gcc compilers. In order to use these compilers, you need to do the following

• Install a current version of Xcode Tools. If Xcode is not already installed, it is freely available from the Mac App Store.

• Once Xcode is installed, the command line tools need to be installed with the following command
  xcode-select --install

It is assumed that you are running a relatively current version of MacOS (Monterey, Ventura, Sonoma or Tahoe). If you are running an older version of MacOS, you may need to make some tweaks to the Makefile to specify correct paths for include files and libraries.

• The X11 library is used to generate screen graphics from an xterm terminal window.

• The Aquaterm library is used to generate screen graphics from a standard MacOS terminal window.

• The readline library is used for command history and command line editing.

• The GD library is used to generate JPEG, PNG, GIF and TIFF format graphics output.

• The Cairo library can be used to generate graphs in X11, Postscript, SVG, PDF or JPEG/PNG/GIF format.

• The Tcl/Tk software is required if you want to run the GUI.

• The libplot library can be used to generate graphs in a a number of different formats.

Note that none of these libraries is essential to running Dataplot (although you need to install either X11 or Aquaterm if you want screen graphics). Either GD or Cairo is needed if you want bitmap graphics (say for importing into Word). The libplot library is probably not needed by most users as most of the devices it supports are already available in Dataplot (it does support Adobe Illustrator and binary CGM which are not otherwise supported). The readline library is convenient, particularly if you are used to using this capability in other programs, but not required.

There are a number of package managers available. Specifically, Homebrew and MacPorts, are currently well supported. Fink, is an older package manager that does not currently support the most recent versions of MacOS. Many MacOS users are likely to have one of these package managers already installed. We do not recommend or require any specific package manager. We provide instructions for the following cases

• you have Macports installed

• you have Homebrew installed

• you do not have a Linux package manager installed

If you use Fink or another of the package managers not given here, you can try modifying the Makefile for either MacPorts or Homebrew.

We do not provide instructions for installing MacPorts or Homebrew as this is provided on the web pages for these programs. Also, we do not currently provide a Dataplot package for MacPorts or Homebrew.
