# Hey, Emacs, this is a -*- Makefile -*-
#
# GNUPLOT Makefile for Cygwin on WinNT and Win95/98/2000
#
# To compile gnuplot for WinXX:
#
# - check the beginning of this file settings you may want to change
#   You'll have to tell it where to find the Help Compiler, among other
#   things.
# - compile the package: go to directory 'gnuplot' and issue the commands
#	 make -C src -f ../config/makefile.cyg
#	 make install -C src -f ../config/makefile.cyg
# - resource compiler used is windres.exe in Cygwin
# - note pdf, png, and gif libraries if used have to be build for Cygwin
#   with -mno-cygwin option
# - -static used for static linking to libz-w.a and libpng-w.a
#

#

# Choose target to compile:
# 1. wgnuplot.exe: The usual Windows GUI for input commands.
# 2. wgnuplot_pipes.exe: The usual Windows GUI with support of pipes, so
#    that e.g.  plot '<awk -f preprocess.awk my.dat')  or  x=system('ls -1')
#    can work. Drawback: wgnuplot_pipes.exe keeps attached to a console (DOS)
#    window it was launched from, or it opens a new one.
# 3. gnuplot.exe: Console mode instead of GUI for the text input.
#
# Comment for programs using gnuplot as their plotting engine:
# Both wgnuplot*.exe compile also pgnuplot.exe. This small helper program was
# used when gnuplot.exe was not available on Windows. Nowadays, pgnuplot.exe
# is deprecated -- please use gnuplot.exe instead.

# GIF, PNG, JPEG device drivers
# Requires gd library. There are two possibilities how to configure these
# drivers for use in gnuplot, depending on the gd version. See README.1ST for
# more details. 
#
# You should compile gnuplot with GD library v2.0 or newer.
# This library writes PNG, GIF and JPEG images.
# If libgd has been compiled with TrueType font support, then you can use
# scaled TrueType fonts in png images. If not, then uncomment FREETYPE.
# Requires GD, PNG and Z libraries, optionally libfreetype.
#

JPEG=1
FREETYPE=1

# PDF device driver

# as opposed to a production build since we lower the optimization level

GNUPLOT_PS_DIR = share/PostScript

# Similarly for javascript files for the canvas terminal:
GNUPLOT_JS_DIR = share/js

# Similarly for lua scripts used by the lua terminal
GNUPLOT_LUA_DIR = share/lua

# Destination directory, used in 'make install':
DESTDIR = /cygdrive/c/Apps/gnuplot

# give here the path to Gygwin GCC compiler unless it is already in PATH

#GCCPATH = /bin/

# Do you want some special optimization?

# To compile the .hlp file you need hcw either out of Microsoft SDK or MS Help
# Workshop. The latter can be obtained at www.helpmaster.com/help/devaids.htm.

# Note: Maybe it does not work properly with pgnuplot (not tested recently).
