# Unix Makefile for XGlk library

# Based on the original by Andrew Plotkin.  Modified to create a shared
# library by Joe Mason.

# XGlk 0.4.11
MAJOR=0
MINOR=4
MICRO=11

# This generates two files. One, of course, is libxglk.a -- the library
# itself. The other is Make.xglk; this is a snippet of Makefile code
# which locates the xglk library and associated libraries (such as
# curses.)
#
# When you install xglk, you must put libxglk.a in the lib directory,
# and glk.h, glkstart.h, and Make.xglk in the include directory.

# If you get errors in xio.c about fd_set or FD_SET being 
#   undefined, put "-DNEEDS_SELECT_H" in the SYSTEMFLAGS line,
#   as has been done for the RS6000.

# definitions for where the X lib and include directories are.
# The following are defaults that might work.

# If your compiler can't find these things, try commenting out the
# above, and uncommenting various versions below. Also look around
# your hard drive for the appropriate files. (The XINCLUDE directory
# should contain the file "Xlib.h", and the XLIB dir should contain 
# "libX11.so" or "libX11.a".)
# The problem is, depending on how things are installed, the
# directories could be just about anywhere. Sigh.
