[Openexr-devel] Include Conflicts

[Brian Clark]

Is anyone out there by any chance using code from the Numerical Recipes 
in C++ book?  I just tried to add some of their code to a project with 
my OpenEXR libraries, and there seems to be a conflict.

If I #include <nr.h> to my Image class which also has half.h, 
ImfArray.h and ImfRgbaFile.h, I get an error about ambiguous 
definitions of functions.  One such example is
static float pow(float x,float y)  in the file ImathMath.h.
But if I move the #includes around, there are functions in <complex> 
that have the same problem.  I'm not even using <complex>, but it's 
included in the nr.h file that is included in all the Numerical Recipes 
.cpp files (and I don't think the functions I'm using are using 
<complex>).

I have used OpenEXR libraries in the past (this same file) before 
adding the NR includes.  I have used the NR includes in a simple 
project where I just tested the NR libraries to see if they did what I 
wanted, and there was no problem.  It's only when I put them together.

It's possible I just have a setting wrong in Xcode (I'm on OSX 10.3.3), 
which is why I want to check if anyone out there has been able to use 
them together.  I will also say that it's possible I'm going about 
including things the wrong way--I'm not experienced with tying other 
people's code into my projects.

Failing having a setting or include order that someone can tell me from 
their experience, I guess I can just go through the nr.h code and 
comment out any libraries that I don't need for this project.  That may 
be a whole new can of worms in messing with other dependencies--I don't 
know.  I've never done anything like that before.

Comments?  Bueller?  Bueller?  Bueller?
