My code looks something like this: try{ fs::path full_path (fs::initial_path()); full_path = fs::system_complete(fs::path(filePath, fs::native)); fs::create_directories(full_path); INFO << "Directory successfully created: " << full_path.native_directory_string() << std::endl; retval = true; }catch(std::exception& ex){ WARN << "Could not create directory: " << filePath << " " << ex.what() << std::endl; } return retval; ========== When filePath is "c:\a\b\", boost throws an exception saying invalid path name c:\a\b\ in path "c:\a\b\" when filePath is "c:\\a\\b\\", boost throws exactly the same exception when filePath is "c:/a/b/", the exception string changes saying invalid path name "c:" in path "c:/a/b/" What am I doing wrong? -Vivek

Set boost::filesystem::default_name_check(boost::filesystem::native); before using path objects as boost uses posix name checking by default. This has been changed in boost version 1.34. On 5/23/07, Vivek Nallur wrote:

That results in a compiler error: C2039 : default_name_check is not a member of boost::filesystem -Vivek On 23/05/07, Arthur Carlsson wrote:

Sorry, my bad. The 'default_name_check' exists in the boost::filesystem::path namespace and not boost::filesystem. However, it has no effect. In other words, I still get the invalid name exception. I'm using Boost-1.33.1 on a windows box. -Vivek On 23/05/07, Vivek Nallur wrote:

New subject: boost::filesystem::path throws exception: invalid name

Is there any mechanism to force boost to check the native filesystem for a path format? Adding default_name_check(boost::filesystem::native) does not seem to help. I'm still getting the invalid name exception. -Vivek On 23/05/07, Vivek Nallur wrote:

The obligatory checking has been entirely removed in 1.34, so upgrading may be an acceptable solution. ~ Scott McMurray

My code looks something like this:

fwiw, the following code works just fine with 1.33.1 on Windows (and you do not need to use default_name_check if don't need to do this for every path) namespace fs = boost::filesystem; fs::path foo_path("c:\\a\\b", fs::native); fs::path bar_path(fs::initial_path()); If you can post the actual code that is causing you problems, it might help to spot the error.

My code looks like this: namespace fs = boost::filesystem; fs::path full_path(fs::initial_path()); try{ full_path = fs::system_complete(fs::path(filePath, fs::native)); ... fs::create_directories(full_path); }catch(exception& ex){ std::cout << ex.what() << std::endl; } Here, 'filePath' is a const char*, that is passed in, which is of the form "c:\\a\\b\\" Upon execution, boost throws an exception saying 'invalid name'. If I change all the back-slashes to slashes, the exception stating 'invalid name' still contains "c:" as the offending string. regs Vivek On 23/05/07, Server Levent Yilmaz wrote:

Funnily enough, full_path = fs::system_complete(fs::path(filePath, fs::no_check)); works on my windows machine! -Vivek On 23/05/07, Vivek Nallur wrote:
