# GNUPLOT Makefile for use on OS/2 2.x (and above)
# using emx 0.9 (and above) and GNUMake
#
# To compile gnuplot, run the following command in directory gnuplot\src:
#	make -f ..\config\makefile.os2
#

# The following tools and libraries are recommended/required to use this
# makefile out of the box:
#	- GNU make, e.g. http://hobbes.nmsu.edu/pub/os2/dev/util/make-3.81beta3-r2-bin.zip
#	- IPFC included in the OS/2 developer kit
#	- emtex is only required for some parts of the documentation
#
#	- GD library, http://hobbes.nmsu.edu/pub/os2/util/gd-2-0-33.zip
#	- GNU readline, http://os2ports.com/ftp/pub/os2/unix/devtools/readline/readline4.1-os2.zip
#	- PDFlib Lite 6.0 or later compiled for emx (available as source from http://www.pdflib.com/ )
#	- XFree86 libraries, ftp://ftp.netlabs.org/pub/xfree86/4.5.0

# We depend on using cmd.exe (or a compatible one) and the
# standard OS/2 tool set. (additionally we use 'cat')
SHELL=cmd.exe

# GIF, PNG, JPEG device drivers
# Requires gd library (not part of gnuplot)
#
# You can use the following set of options for GD library v2.0 something
# or newer. This library writes PNG, JPEG and GIF 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.
# The pre-compiled GD library by Ilya Zakharevich available at 
# http://hobbes.nmsu.edu/pub/os2/util/gd-2-0-33.zip
# is strongly recommended. This packages already includes the required

# saving of history (no longer requires GNU readline)

# DEBUGging support
# creates binaries suitable for debugging. Some bugs may come and go
