Was there some change to Xcode (and the entire tool chain) in Xcode 2.4 that would affect the isnan(x) function? I have now come across two open source packages that get hung up on "isnan(x) is undeclared in this context" type errors. The projects are OpenSceneGraph (www.openscenegraph.net) and ITK (www.itk.org). In ITK's case I had to change a #define to look like the following: #if defined(__APPLE__) #if (__GNUC__ >= 4) #include <cmath> #define isnan(x) std::isnan(x) #else #include <math.h> #define isnan(x) __isnand((double)x) #endif #endif Where as it used to be just: #if defined(__APPLE__) #include <math.h> #define isnan(x) __isnand((double)x) #endif Just curious.... -- Mike Jackson imikejackson <at> gmail <dot> com _______________________________________________ Do not post admin requests to the list.
