Hi Wesley, I created this file ------------------------------ #include <iterator> ------------------------------ g++ -a wesley.cpp No problems. Running Darwin, using either GCC 3.3 (g++-3.3) or GCC 4.0 (g++-4.0). Can you create a small source file that replicates the behavior, and post it to this forum? >Any ideas as to whjat might cause this? Not sure. My first guess is: bad code in main.cpp, Magick++.h, or Magick++/STL.h. Thanks, --Eljay
