Regex unknown error msvcrt!_iob under Qt 4.8 built with latest mingw-builds [Solved]
-
I have just built Qt 4.8 with the latest mingw-builds, all my c++ projects works fine, except this line:
regex r("\\d+");
which works fine at my friend PC with Qt 4.8 but debugged with msvc2010.
If I'm writing this line:regex r;
it's doesnt break on this line, but then any thing I'm trying to do with "r" leading to the same unknown error result.If I look at Qt debug window on the table of (Level,Function,File,Line), I can see:

@Lol4t0:
std::regex is part of c++11 standard library.Mingw must haven't included support of regular expressions yet, while VS 2010 supports them.
However, you can use QRegExp instead.
@my response:
I was pretty sure mingw-builds project have includes most of the c++11, but apparently not. I changed my code to work with QRegExp, and it's even cleaner and simple then before.
