Dear boosters, I got 25 warnings in total from "boost/filesystem/path.hpp" and "boost/filesystem/operations.hpp" about "comparison between signed and unsigned integer expressions". This is because the type of dot<Path>::value (and the likes, e.g slash<Path>::value) is char regardless of the type of Path::value_type, which is an unsigned integral type in case of wchar_t. Obviously, they are not errors but for me, these 25 warnings are too much and unfriendly. I hope this will be fixed in future version of Boost. Thank you for reading this. Best regards, An P.S: I use gcc(winxpsp2/linux) + boost 1.36.0 + stlport 5.1.6 --------------------------------- Đặt ngay địa chỉ email mới!
