# makefile for Triangle and Show Me

|
|
# Type "make" to compile Triangle and Show Me.
|
|
#
|
|
# After compiling, type "triangle -h" and "showme -h" to read instructions
|
|
# for using each of these programs.
|
|
#
|
|
# Type "make trilibrary" to compile Triangle as an object file (triangle.o).
|
|
#
|
|
# Type "make distclean" to delete all object and executable files.
|
|
|
|
# SRC is the directory in which the C source files are, and BIN is the

# directory where you want to put the executable programs. By default,
|
|
# both are the current directory.

# CSWITCHES is a list of all switches passed to the C compiler. I strongly
|
|
# recommend using the best level of optimization. I also strongly
|
|
# recommend timing each level of optimization to see which is the
|
|
# best. For instance, when I had a DEC Alpha using DEC's optimizing
|
|
# compiler, the -O2 switch generated a notably faster version of Triangle
|
|
# than the -O3 switch. Go figure.
|
|
#
|
|
# By default, Triangle and Show Me use double precision floating point
|
|
# numbers. If you prefer single precision, use the -DSINGLE switch.
|
|
# Double precision uses more memory, but improves the resolution of
|
|
# the meshes you can generate with Triangle. It also reduces the
|
|
# likelihood of a floating exception due to overflow. Also, it is
|
|
# much faster than single precision on many architectures. I recommend
|
|
# double precision unless you want to generate a mesh for which you do
|
|
# not have enough memory to use double precision.
|
|
#
|
|
# If yours is not a Unix system, use the -DNO_TIMER switch to eliminate the
|
|
# Unix-specific timer code. Also, don't try to compile Show Me; it only
|
|
# works with X Windows.
|
|
#
|
|
# To get the exact arithmetic to work right on an Intel processor, use the
|
|
# -DCPU86 switch with Microsoft C, or the -DLINUX switch with gcc running
|
|
# on Linux. The floating-point arithmetic might not be robust otherwise.
|
|
# Please see http://www.cs.cmu.edu/~quake/robust.pc.html for details.
|
|
#
|
|
# If you are modifying Triangle, I recommend using the -DSELF_CHECK switch
|
|
# while you are debugging. Defining the SELF_CHECK symbol causes
|
|
# Triangle to include self-checking code. Triangle will execute more
|
|
# slowly, however, so be sure to remove this switch before compiling a
|
|
# production version.
|
|
#
|
|
# If the size of the Triangle binary is important to you, you may wish to
|
|
# generate a reduced version of Triangle. The -DREDUCED switch gets rid
|
|
# of all features that are primarily of research interest. Specifically,
|
|
# defining the REDUCED symbol eliminates the -i, -F, -s, and -C switches.
|
|
# The -DCDT_ONLY switch gets rid of all meshing algorithms above and beyond
|
|
# constrained Delaunay triangulation. Specifically, defining the CDT_ONLY
|
|
# symbol eliminates the -r, -q, -a, -u, -D, -S, and -s switches. The
|
|
# REDUCED and CDT_ONLY symbols may be particularly attractive when Triangle
|
|
# is called by another program that does not need all of Triangle's
|
|
# features; in this case, these switches should appear as part of
|
|
# "TRILIBDEFS" below.
|
|
#
|
|
# On some systems, you may need to include -I/usr/local/include and/or
|
|
# -L/usr/local/lib in the compiler options to ensure that the X include
|
|
# files and libraries that Show Me needs are found. If you get errors
|
|
# like "Can't find include file X11/Xlib.h", you need the former switch.
|
|
# Try compiling without them first; add them if that fails.
|
|
#
|
|
# An example CSWITCHES line is:
|
|
#
|
|
# CSWITCHES = -O -DNO_TIMER -DLINUX -I/usr/X11R6/include -L/usr/X11R6/lib
|
|
|
|
CSWITCHES = -O -DLINUX -I/usr/X11R6/include -L/usr/X11R6/lib

# TRILIBDEFS is a list of definitions used to compile an object code version
|
|
# of Triangle (triangle.o) to be called by another program. The file
|
|
# "triangle.h" contains detailed information on how to call triangle.o.
|
|
#
|
|
# The -DTRILIBRARY should always be used when compiling Triangle into an
|
|
# object file.
|
|
#
|
|
# An example TRILIBDEFS line is:
|
|

# TRILIBDEFS = -DTRILIBRARY -DREDUCED -DCDT_ONLY
