Downloading DRAWxtl

To allow us to notify you when we update the programs, please send E-mail to Larry Finger when you first download any of these versions.

We are pleased to announce a upgrade of both versions of this program. V5.5, which incorporates a full graphical user interface (GUI), is built using the Fast Light Tool Kit (FLTK) V1.1.9 or V1.3.0, and for Windows, the FLTK Utility Widgets (FLU), which are available through www.fltk.org. V4.5 includes all the same features, but not the GUI, and can be configured to disable the real-time display if so desired. The file read.txt in the distribution kit, or the 'Changes' tab above describes other changes. As before, we ask you to send us E-mail regarding any residual bugs, or features you would like to see added. For bugs, please send a brief description of the problem, information about the platform upon which you are working, the name and version of the compiler you are using if self compiled, and a copy of the data file that shows this problem.

Windows

The Windows versions now come with an installer program that unpacks the files into the appropriate folders. To install the program, download either DRAWxtl_install55.exe or DRAWxtl_install45.exe, execute it and answer the questions. It will install the program in any folder you desire and optionally create shortcuts on the desktop or in the "quick launch" area. Included are the Windows executable, sample input files, the documentation in PDF format, and the executable for the graphical shell (V4.5). If you wish to compile the program, the source (*.cxx, *.c and *.h) files are contained in DRAWxtl_src_install55.exe or DRAWxtl_src_install45.exe. N.B. you will need FLTK 1.1.9 or 1.3.0 from http://www.fltk.org and FLU_2.14 from http://www.osc.edu/~jbryan/FLU/ to build V5.5.

LINUX and UNIX

For Linux and other flavors of UNIX, the primary distributions are DRAWxtl55.tar.gz, or DRAWxtl45.tar.gz tar-format files, compressed with GZIP. Each includes the appropriate source files for the g++ or gcc compilers, a Makefile, sample input files, and the manual in DOC and PDF formats. Source for the shell is also included with V4.5. To build these versions, libraries and headers for openGL, GLU, GLUT, and FLTK (for V5.5 and the shell) are needed; however, V4.5 can be built without the openGL display window. Most distributions provide the necessary libraries and headers in the form of development packages such as fltk-dev, etc. For users of the Debian distro, a DRAWxtl package is available. Binaries for Linux are available upon request. Please specify if 32- or 64-bit executables are needed.

Note that each Makefile has sections to set compliation and link options as needed for Linux, Cygwin, and OS X. Use on other Unix platforms will likely require some tweaking to adjust for library locations, etc.

If you build from source and use a version of GLUT other than freeglut, you will need to remove the GLUT=-DFREEGLUT24 line in the makefile.

Mac

Mac users (OS X only) may either download DRAWxtl55.tar.gz, or DRAWxtl45.tar.gz tar-format files, and build the program themselves. Building requires Mac development environment including the OpenGL libraries. For V5.5 or the V4.5 shell, the FLTK libraries must also be downloaded and built. Mac-specific dmg files are available through DRAWxtl55.dmg, which is a universal version for Intel and PPC (G4) CPUs. This file contains the compiled binary for DRAWxtl V5.5, and an AppleScript app for each program to integrate the programs on the Mac. The file is a compressed disk image (.dmg) file. When one clicks on this file, it is mounted as a read-only file system. One can then run the software from the disk image, but a better choice is to drag the folder to the hard disk and run from that location. Input for DRAWxtl (typically .str files) can be run by dragging the files onto the DRAWxtl55 app in the DRAWxtl directory. The app can also be dragged onto the doc. To create a shortcut to DRAWxtl in any other location than the dock (for example, on the desktop), create an alias in the desired location (for example by dragging the icon while holding command and option together). The current version does not include DRAWxtl V4.5 nor the shell for it. Any Mac user that uses this version should contact the authors.

Use care when copying individual files. The AppleScript apps must be copied together with the exe directory and its contents for the script to function. Better yet, create an alias to the AppleScript(s); put the alias where you want and leave the files as distributed.

openVMS

The port of DRAWxtl to openVMS was done by Jouk Jansen of the Technical University of Delft, Netherlands. No precompiled binary is available for this platform. If you wish to use DRAWxtl on openVMS, please consult his web page nchrem.tnw.tudelft.nl/openvms/software2.html#DRAWxtl to download the patches to the source files in DRAWxtl55.tar.gz. Jouk's site also has information regarding the ports of the other software (FLTK-1.1.*, Mesa and XPM) needed to build DRAWxtl on openVMS.
