Hi,

The file endian.h is typically found on *nix-like systems and provides
macros to test little/big-endianness of the target processor.

It seems that #include <endian.h> (see png++/config.hpp) doesn't find
the file on Mac OS.  I believe that correctly formed endian.h should
be present on your system, but is placed at some other location.

You can try to use this command:

$ locate endian.h

to find the correct path to this file.  Then adjust config.hpp like this:

#if defined(__GLIBC__)

#if defined(???) // some macro defined when compiling on Mac OS

#include <???/endian.h>

#else

#include <endian.h>

#endif

#elif defined(__WIN32)
...

Please keep the mailing list in CC: to help other Mac OS users. ;)
