[Solved] stddef.h no such file or directory

[mqw00058]

I installed Qt creator and then Qt library-mingw on Window system.

I tried to compile an example code in the Qt Creator but I got the error message.

Mabe 'stddef.h' is one of c++ headers.

I think that the Qt Creator is not connected to mingw.

What should be set or changed in Qt Creator option?
I tried to add INCLUDEPATH to Build environment variables in QtCreator but still not working.

Hi, mqw00058,

Welcome to the forum.

Can you tell us: How did you install Qt? Where did you get it from? OS?

[mqw00058]

I dowload qt frome http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-win-opensource-4.8.5-mingw.exe

[Eddy]

Can you check you environment variables?
is PATH pointing to your mingw/bin directory?

[mqw00058]

Thank you so much.

After the mingw/bin directory path is added to PATH variable in Build Environment of QtCreator, it works now.

I'm glad it's working now.
