Assignment 1 Information

Assignment 1 support code is out: gzipped tar file or zip file. See the getting started section below.
Libraries you will need:
- CGAL (The UNIX installation should be pretty straightforward. Kris put together some tips on installing CGAL under Windows.)
- dolt (If you install "dolt" on your own computer, you will need to compile it with CGAL support.) See notes on installing dolt under linux below.

Getting Started

On the CS department Suns, you will need to edit your .bashrc file to include the following lines:

export CGAL_MAKEFILE=/projects/cgal/CGAL-2.4/make/makefile_sparc_SunOS-5.8_g++-2.95
export DOLT_MAKEFILE=/projects/arl/make/Makefile-dolt

After you have done this, you should run the command:

$ source ~/.bashrc

That will make sure that these environment variables are set. In the future, your new .bashrc file will be executed when you log in.

Create a directory to work in, and Download the a1code.tar.gz file to this directory. Then do the following:

$ tar xfz a1code.tgz
$ gmake
$ ./assign1 Problem1.txt

Compiling the program will take a minute and produce a bunch of output. When you run the executable, it should open a window and draw the world. Press 'h' to get a list of commands.

Notes on installing dolt (under linux)

If you are installing dolt on a linux system, you will need to install GLUT and OpenGL. Actually, what you'll need is MESA, an open source version of OpenGL. Here are the packages that I have installed on my mandrake-linux system (YMMV):
```
libMesaGLU1-devel-4.0.1-4mdk
libMesaglut3-devel-4.0.1-4mdk
libMesaGLU1-4.0.1-4mdk
libMesaglut3-4.0.1-4mdk
libMesaGL1-4.0.1-4mdk
```
You need to install CGAL first and set the CGAL_MAKEFILE variable in your environment (through your .bashrc file which you'll have to source)
After unpacking the files, you should be able to:
```
$ make cgal
```
Note that you have to use GNU make, which might actually be called gmake on your system. If you just do a "make", that will make the version of the library without CGAL geometric representations. This won't hurt, but it is not needed.
Check the INSTALL_DIR variable in the Makefile (the default is /usr/local). Either change it to what you want or set the variable (and export it) in your shell. Then do:
```
$ make install
```
(possibly as root depending on what permissions you have on your install directory)
Make sure you set the DOLT_MAKEFILE variable to point to $(INSTALL_DIR)/make/Makefile-dolt
