Hi,
I'm trying to compile some image processing software that uses isnan.
I'm using gcc 3.3, so (as was pointed out earlier) the c99 extensions
aren't in c++ yet. Thus, when I include on cmath I get a 'isnan'
undeclared error. The same goes for when I include both cmath and
math.h. When I just include math.h however isnan is defined and I can
compile.
In compiling this software, I need to somehow figure out how to use
both the isnan from math.h and cmath for the other functions defined
there in the same header file but not have them conflict. Are there
any compiler settings of macros that can be used to do this?
thanks,
wes
PS is this still an issue under Tiger with gcc 4.0?
