i have a
ifstream m_ifsInput
variable and I try to open a file like this:
m_ifsInput.open( sFileName.c_str() );
where sFileName is a std::wstring variable
the error i get when compiling with g++

no matching function for call to ‘std::basic_ifstream<char, std::char_traits<char> >::open(const wchar_t*)’

the thing is the same thing compiles well uner windows. Looking at the error i get with g++ would mean that there is no open method that takes a wchar_t* as parameter, but then, why the heck does it compile with visual studio ??? I mean it's a standard library function.. these should port ...

g++ is correct. The C++ standard doesn't define an open member function that takes const wchar_t* as a filename type.

Visual Studio is correct. Nothing stops an implementation from supporting extensions to the standard classes as long as the standard stuff is conformant.

>I mean it's a standard library function.. these should port ...
If you rely on extensions, you can't expect your code to be portable.
