Thanks, Lars I defined the macros only for my code and now everything compiles. I have a question regarding the deprecated function path::normalize(). Before moving to V3 I used this function to resolve paths containing "..". For example: path myPath("/Dir_A/Dir_B/a.txt/.."); myPath->normalize(); now myPath is: "/Dir_A/Dir_B" Can this be done using V3 code? Thanks, Shai
