问题 So... I have a base path and a new path.New path contains in it base path. I need to see what is different in new path. Like we had /home/ and new path is /home/apple/one and I need to get from it apple/one. note - when I would create some path from (homePath/diffPath) I need to get that /home/apple/one again. How to do such thing with Boost FileSystem? 回答1: Using stem() and parent_path() and walk backwards from the new path until we get back to base path, this works, but I am not sure if it

问题 Given: filesystem::path toDir("./"); ptime oldTime; ptime now(second_clock::local_time()); How can I determine which files were created in the time period between oldTime and now ? The names of such "fresh" files should be streamed to cout . Update: Well based on given answer I made a small programm: #include <sstream> #include <stdio.h> #include <time.h> #include <boost/filesystem.hpp> #include <boost/thread.hpp> #include <boost/timer.hpp> #include <boost/date_time.hpp> #include <boost/date

问题 I have a Visual Studio 2008 C++03 application using Boost 1.47.0 running in Windows XP SP3. The call boost::filesystem::create_directories( L"c:\\foo\\bar" ); throws a std::bad_alloc exception. In the output window, I see a debug heap message: "HEAP[test.exe]: Invalid allocation size - CDCDCDCE (exceeded 7ffdefff)" The callstack shows boost.filesystem creating a new locale and last visible line of code in the Microsoft standard library file xlocale line 309. msvcp90.dll!std::_Allocate<char>()

问题 I'm using OS X 10.7.3. I've been playing with the boost headers for a while now and i wanted to move onto using the Boost.Filesystem lib however it keeps throwing this message at me: Undefined symbols for architecture x86_64: "boost::system::generic_category()", referenced from: __static_initialization_and_destruction_0(int, int)in ccOhIhNG.o boost::filesystem3::detail::create_directories(boost::filesystem3::path const&, boost::system::error_code*)in libboost_filesystem.a(operations.o) boost:

问题 First off, I'm using Visual Studio 2015's implementation of the Filesystem library from the upcoming C++17 standard, which is based on Boost::Filesystem. Basically, what I'm trying to do is save a file's timestamp (it's "last write time"), copy that file's contents into an archive along with said timestamp, then extract that file back out and use the saved timestamp to restore the correct "last write time". // Get the file's 'last write time' and convert it into a usable integer. __int64

问题 Given below code: #include <iostream> #include <filesystem> namespace fs = std::filesystem; int main() { fs::path fsBase = "/base"; fs::path fsAppend = "/append"; auto fsResult = fsBase / fsAppend; std::cout << "fsResult: " << fsResult << std::endl; return 0; } Usually, the expected result is /base/append , but it actually gives /append . The description of fs::path::append does indicate this behavior: If p.is_absolute() || (p.has_root_name() && p.root_name() != root_name()), then replaces
