Hi, I upgraded to boost version 1.43, but that did not help. Still file creation fails with wfstream and error code set is ERROR_FILE_NOT_FOUND. Below code captures the error codes #include "boost/filesystem/fstream.hpp" int main() { boost::filesystem::path pA("C:\\testA.txt"); boost::filesystem::wpath pW(L"C:\\testW.txt"); boost::filesystem::fstream fileHandleA; boost::filesystem::wfstream fileHandleW; fileHandleA.open(pA, std::ios_base::out); cout << "fileHandleA.fail() return value is: " << fileHandleA.fail() << endl; cout << "Error code is: " << GetLastError() << endl; fileHandleW.open(pW, std::ios_base::out); cout << "fileHandleW.fail() return value is: " << fileHandleW.fail() << endl; cout << "Error code is: " << GetLastError() << endl; return 0; } Am I doing something wrong?

Hello,

I am using boost version 1.42 and the below code is tested on Windows Xp SP3 and Suse 11.2

The below code creates new file when opened using fstream object, but fails to create when opened using wftream object. This behavior is consistent across platforms (Windows and Linux). Also the error code which I get after fileHandleW.open call is,

 1.  ERROR_FILE_NOT_FOUND for  std::ios_base::out  2.  ERROR_NEGATIVE_SEEK for std::ios_base::app

In case of append mode, the file gets created. But still I get the above mentioned error code.
