Has anyone recently compiled the redbook examples found here

http://opengl-redbook.com/code/

with the provided makefile?

I am pretty damn sure I have all the libraries needed installed from my
ubuntu repository, but get

shadowmap.c:49:21: error: helpers.h: No such file or directory

helper.h seems to be not a library-specific header. it should belong to 
the redbook examples.
so, look for it in the example folder and add "-I/path/to/the/folder" to 
the CXX_FLAGS variable in the makefile

You have compiled them?

There is no helpers.h.

(There is also no CXX_FLAGS variable in the makefile)

I am compiling on Ubuntu linux.

I just downloaded them. Forget about the makefile. Just try this:

g++ the_example_you_want_to_compile.c -lGL -lGLU -lglut -o any_output_name

Thanks for the replies. I'd already ditched the Makefile and made my
own.

I'm at a loss to explain how it can be so wrong considering the Linux
install base and nothing is mentioned in the errata.

Now I am in the process of sorting out differences between Mesa, glut,
freeglut and the nvidia-glx drivers. I lost my X this morning :(

FWIW and if anyone has problems with this, here is my Gcc Linux Makefile
for the opengl programming guide (redbook) code examples using C:

I installed freeglut and NOT mesa to make this compile and
work. Unfortunately a whole host of examples out there assume Mesa.

Assume Mesa in what way ? nvidia-glx should (does!) provide all the "real" 
OpenGL stuff you need.

Like all the makefiles referencing non existing mesa libraries?

It's, as a nOOb, very confusing.

Why should nvidia-glx be providing the stuff I need? Does this mean
anything I link to will NOT work with ATI cards? Please, be patient with
me. There is a lot of stuff out there.

I assumed all the openGL stuff for compiling and linking would be card
neutral and that code then talks to the correct openGL for the Nvidia
card or ATI card at run time.

Your assumption was correct...

 You are correct -- as long as you use the proper OpenGL header syntax, and 
don't include any MESA stuff -by name-.
If you have nvidia-glx (or ati devkit) installed on your Linux box, they 
suercede and replace MESA -- if you install Mesa on top of them, it will 
just bess everything up and neither will work right.

So, which "non existing mesa libraries" do the makefiles reference? You 
should typically need

-lGLU -lGL -lXm -lX11 -lm more or less as libraries to link with.

if you explicitly link with -lMesaGLU, fore example, then you aren't 
portable to non-mesa installations.

nVidia and ATI "driver" installs on linux *replace* -lGL and -lGLU default 
Mesa installations with their own.

They also replace the include files "gl.h and "glx.h"" with their own.

This was the problem then : the example code I had did indeed include
mesa stuff by name

e.g -lMesaGLU

Amazing how messy "releases" of examples like this can slow up a
beginner. It took me the bones of 8 hours to get to a stage where I
could compile the red book examples - including loss of Linux display
.....

The fact that the redbook doesnt come with a working Linux makefile is
somewhat surprising too.
