COMPILATION INFORMATION

XSPICE has been successfully compiled on HP Apollo and Sun
workstations.  The source files require approximately 10Mb of
disk space and the entire compiled system requires approximately
30Mb of space on HP Apollo platforms.  The resulting executable
size depends on the number of models included.  On HP Apollo
platforms with all supplied code models, the XSPICE executable
is approximately 2.5 Mb.

The following software is required for compilation:

    UNIX BSD4.3 or compatible operating system
    UNIX Lex, Yacc, and Sed utilities
    X11R4 X Window System with Athena Widgets
    ANSI compatible C compiler


If your system does not have an ANSI compatible C compiler named cc,
edit the 'CC=cc' line in /usr/local/xspice-1-0/include/make.include
to specify the name of the ANSI C compiler on your system
(e.g. 'CC=gcc').


To build the XSPICE system, move into the 'src' subdirectory
and execute 'make'.
