This package contains X11/GUI development utilities and applications developed by the IRAF Project, National Optical Astronomy Observatories, since 1994. It provides the following programs:
XGterm provides a Tek 4012 compatible graphics terminal emulation plus, for clients in the know, a datastream driven widget server capability using the Object Manager to provide full access to the underlying toolkit and widget set. The remote client application downloads a GUI file to the widget server (xgterm) which executes the GUI. While the GUI is executing it exchanges messages with the remote client application at runtime via interprocess communication. In the case of Xgterm, this currently uses a serial (tty based) protocol.
XImtool is an image display server. This provides an image display capability to remote client applications using the standard imtool/iis image display protocol. The image display server allows a number of image frame buffers to be created and displayed. The client can read and write data in these frame buffers. Any frame or combination of frames can be displayed. Various display options are provided, e.g., zoom and pan, flip about either axis, frame blink, windowing of the display, and colortable enhancement.
The source code if x11iraf is mostly Open Source conform to the Open Source
Definition by the Open Source Initiative.
The list of files that are not conform is documented in the file
of the source package. Note that x11iraf can be built without using these
The x11iraf package is maintained on Github. The preferred way to report a bug is to create a new issue on the x11iraf GitHub issue page. To contribute patches, we suggest to create a pull request on GitHub.
On some systems, x11iraf can be directly installed from the package repositories:
Ubuntu 19.10 “Eoan Ermine” and later,
Debian 11 “Bullseye” (also in Debian 10 “Buster” backports),
Mageia 4 and later
Packages for Arch Linux are currently in preparation. Please contact us if you want to help packaging for macOS or other Linux versions.
The X11IRAF sources are available from github at
System Requirements and Dependencies
Besides a normal development environment (C compiler, make, lex, yacc), the installation requires the ncurses, X11 (xaw, xaw3d, xmu), TCL and XPM libraries to be installed. To compile the helper for ximtool, also a working IRAF installation with its development tools is required.
On Debian and its derivatives (Ubuntu, Mint, Devuan, Raspbian etc.):
$ sudo apt install gcc make bison flex libncurses-dev tcl-dev $ sudo apt install libxaw7-dev libxmu-dev xaw3dg-dev libxpm-dev $ sudo apt install iraf-dev
On MacOS X (both Intel and ARM systems work), you need to have the XCode tools installed. If you haven’t, you can install them with:
$ xcode-select --install
Click “Install” to download and install Xcode Command Line Tools. Additionally, you need to install XQuartz from www.xquartz.org.
ism_wcspix.e helper of XImtool, you also need a working IRAF
installation. Make sure that the
xc compiler works and can be found in the
Unpack the Source Tarball
The source distribution file is built as a tarball with the package name and version as base directory. Thus, distribution files can be unpacked with the command
$ tar xzf /<path>/x11iraf-2.1.tar.gz $ cd x11iraf-2.1/
Build from Sources
In the source directory, type
This will automatically compile all sources and create the executables
ximtool/ximtool, and the helper
ximtool/clients/ism_wcspix.e. The compilation can be tuned by
LDFLAGS. If the environment variable
OSI_COMPLIANT is set to
YES, the build uses only source files that
are Open Source.
To copy the executables to
# sudo make install
This will also install the manpages to
/usr/local/man/ und the
required terminfo file for xgterm to
/usr/share/terminfo/. If you
don’t want to invoke
make install, you should make sure to run
tic xgterm/xgterm.terminfo to compile and install the terminfo file.
Use another font on xgterm
On modern, HighDPI monitors, xgterm often appears too small to be
usable. The reason here is that xgterm uses the “fixed” font by
default. The “lucidasanstypewriter” font family is available by
default on many system and provides font sizes that fit on many
screens. To try it out, start xgterm with the option
lucidasanstypewriter-14. Available font sizes are 12,14,16,18,20, 22,
24, 28, 32.
To make the font setting default, put the selected font into the
~/.Xresources (create the file if it does not exist):
and load them into the X11 resources with
$ xrdb ~/.Xresources
Other fonts can be used as well as long as they are fixed width (typewriter) X11 bitmap fonts. One font worthwile to try out is “terminus” (package “xfonts-terminus” on Debian/Ubuntu/Mint systems).
Other included programs
The sources include a few more programs that are out of interest for the normal user:
The guidemo package illustrates how to use GUIs in IRAF applications.
The obmsh package provides a simple shell for the IRAF Object Manager.
XTapemon is a conventional Xt/Athena application which allows the status of an IRAF tape job to be monitored continuously while the tape is being accessed.
These programs are not built by default.
