Compile error on Centos 6.2

[mattebb]

Hi,

I get a strange compile error building partio on centos 6.2. I'm actually building the redpawfx fork, but at a glance, it looks like the issue is not in the forked changes, so I'll post the issue here - please let me know if you'd like me to move the issue to that repo!

Anyway, when building the PDB files, I get a lot of errors similar to this
[ 20%] Building CXX object src/lib/CMakeFiles/partio.dir/io/PDB.o

I'm not an expert with C++ build issues, but I noticed it was looking at PDB::fgetc, which seems like it's putting the standard library stuff in the PDB namespace. I edited PDB.cpp and removed the:
namespace PDB
from around:
#include "pdb.h"

and put the namespace PDB in pdb.h directly, after

#include <stdio.h>
#include <stdlib.h>

This now compiles correctly.

Is this a genuine bug? Or maybe a mis-configuration on this system?

cheers
