(part1b) Han from China teaches you C

HeY KiDz!

Another week, another part of Han's award-winning C/C++ tutorial. After
last week's slightly unix centered material, this time we'll develop a
truly multi-platform "Hello World" type program.


PART1b: Hello, World, 1b
========================

During the course of this lesson you'll learn a bunch of stuff.


1b.1 Preparations
-----------------

In order too compile this weeks code, you'll need the GLUT library. On
most modern operating systems, this library is already part of your OS
installation medium, so just install it now (be sure to install
development packages as well). We'll be using only basic features,
so freeglut will do too.
Windows users can get GLUT at <http://www.xmission.com/~nate/glut/>.
Gentoo users can bite my shiny metal ass.


1b.1.1 Special note for lcc-win32 users
---------------------------------------

Unfortunately, the GLUT32.LIB import library shipped with lcc-win32 is
very old and more than one decade out of date. To remedy the situation,
first make backup copies of GLUT32.LIB and GLUT32.EXP. Next, at the end
of GLUT32.EXP, add these three lines:

___glutInitWithExit@12
___glutCreateWindowWithExit@8
___glutCreateMenuWithExit@8

Use the BUILDLIB.EXE utility and regenerate GLUT32.LIB. Done.


1b.2 Excercises
---------------

None this week, just be sure to familarize yourselves with the the code
and understand it completly before continuing with the next lesson
(we'll be using most of the code again in the lesson about stacks).
As always, you can ask any questions where the C experts hang out,
in comp.lang.c.
