QStringList Compile Problem

I get a compile error when using QStringList. I have a very simple program:

#include "QApplication.h"
#include "QStringList.h"

int main(int argc, char* argv[])
{
QApplication app(argc, argv);
QStringList strList;
strList << "one" << "two" << "Three";

return app.exec();
}

I do the qmake -project, then qmake testproj.pro, then make. I am using mingw and QT 4.3.2.

I get the following error:
C:\Users\ajonesfl\Cpp Projects\Examples\testproj>make
mingw32-make -f Makefile.Release
mingw32-make[1]: Entering directory `C:/Users/ajonesfl/Cpp Projects/Examples/testproj'

mingw32-make[1]: Leaving directory `C:/Users/ajonesfl/Cpp Projects/Examples/testproj'
mingw32-make: *** [release] Error 2

When I comment out the line: strList << "one" << "two" << "Three";

The program compiles..... Any help would be appreciated on this. Thanks

hi
I compile your code and it run without Problem
note:
if you will not create any GUI object replace
return app.exec();
with
return 0;

because the program still run in memory in the first case

QStringList Compile Problem

Thanks for your reply, but it was not helpful. What the problem turned out to be was that I did not have the correct libraries that match the header files that I had. So if any one gets this type of error in the future, make sure your headers files versions are in sync with the libraries versions.

I believe my files got out of sync when I upgraded to a newer version of QT.
