Problem when run Qt MinGW

[Yunan Luo]

I just downloaded and installed Qt 5.1.1 MinGW Window. Then I open the example project calculator but encounter problems when I click RUN. The compile outputs are like

@c:\qt\qt5.1.1\tools\mingw48_32\lib\gcc\i686-w64-mingw32\4.8.0\include\c++\cstdlib:72: In file included from c:\qt\qt5.1.1\tools\mingw48_32\lib\gcc\i686-w64-mingw32\4.8.0\include\c++\cstdlib:72:0,@
@c:\qt\qt5.1.1\tools\mingw48_32\i686-w64-mingw32\include\stddef.h:21: error: 'errno_t' does not name a type
errno_t __cdecl _get_errno(int *_Value);
^@
@c:\qt\qt5.1.1\tools\mingw48_32\i686-w64-mingw32\include\stddef.h:7: In file included from c:\qt\qt5.1.1\tools\mingw48_32\i686-w64-mingw32\include\stddef.h:7:0,@

There are many this kind of errors (80+ issues)

welcome to devnet

Are you using Qt creator as IDE or are you trying to compile from a command prompt?

In Qt creator you could create a project and program from template and try to compile. In general this should work when the setup is ok.

koahnig, I'm using Qt creator as IDE. The calculator project is from Qt examples and I didn't change anything in it.
I think maybe it has something to do with compiler? As it reported something wrong with <cstdlib> and <algorithm>..

Creating a project from template and trying to compile helps to understand if it is a setup problem or something wrong with the example code.
