- # 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.
- SRC = ./
- BIN = ./
- # CC should be set to the name of your favorite C compiler.
- CC = cc
- # 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
- TRILIBDEFS = -DTRILIBRARY
- # RM should be set to the name of your favorite rm (file deletion program).
- RM = /bin/rm
- # The action starts here.
