Using CGAL on sun.cs.tamu.edu

To use CGAL on the sun.cs.tamu.edu machine:

1. Uncompress the file /tmp/cgal-boost.tgz in your home directory

           cd ~
   	tar zxf /tmp/cgal-boost.tgz
         

   The previous command will create opt directory in your home. Inside, there are 4 directories: bin, include, lib and share.

   The opt/include directory are the headers files for CGAL (version 3.4) and boost (version 1.40) and the opt/lib contain the libraries for CGAL (dynamic) and boost (static and dynamic)

2. To compile code using CGAL, use the following Makefile:

   # Makefile to compile code using CGAL
   # Set CGAL_DIR to the directory where the cgal includes and libraries are
   CGAL_DIR=${HOME}/opt
   
   INCLUDES += -I${CGAL_DIR}/include
   LIBS += -L${CGAL_DIR}/lib -lCGAL -lboost_thread -lgmp -lmpfr
   CFLAGS += -O3 -frounding-math
   CPP = g++
   
   %: %.cc
           ${CPP} ${CFLAGS} ${INCLUDES} ${LIBS} -o $@ $<
         

3. Write your code and save it with extension .cc (e.g. simple_demo.cc) and run

   	make simple_demo
       

   to compile the code.

4. To run your previous compiled program, define the LD_LIBRARY_PATH environment variable to $HOME/opt/lib

   Using bash shell:

           export LD_LIBRARY_PATH=$HOME/opt/lib
