This emulator was built on RedHat Linux 4.2 (kernel 2.0.30) with the following installed software:

• gcc version 2.7.2.1
• gnu make 3.75
• Tcl/Tk versions 7.6 and 4.2 respectively

It has also been successfully built on RedHat Linux 5.0 (kernel 2.0.32) with:

• gcc version 2.7.2.3
• gnu make 3.76.1
• Tcl/Tk versions 8.0

(Note: dialog.tcl is expected to be in /usr/lib/tk. On my setup I have made this a soft-link to the real location, viz. /usr/lib/tk8.0)

The Makefile is configured by the following environment variables:

• MACHINE: the host cpu type (e.g. i686)
• OS: the host operating system (e.g. Linux)

The LD_LIBRARY_PATH environment variable must contain the shared objects' location, e.g., if the emulator is to be executed in situ:

$ export LD_LIBRARY_PATH=$OS-$MACHINE:$LD_LIBRARY_PATH
$ ./tk-emul8 uk101

The emulator takes an optional parameter naming either an initial configuration (uk101/mon02.tcl) or a directory containing a file called config.tcl.
