This simple program compiles nicely on Linux+gcc 6.3.0 but fails to
compile on x86_64-w64-mingw (6.3.0, std=c++14):
#include "nowide/fstream.hpp"
int main() {
auto f = nowide::fstream("toto.log");
return 0;
}
instead of
auto f=...,
nowide::fstream f("toto.log")
works fine.
The error is:
toto.cpp:4:38: erreur : use of deleted function «
nowide::basic_fstream<char>::basic_fstream(const
nowide::basic_fstream<char>&) »
auto f = nowide::fstream("toto.log");
