[SOLVED] QTCreator stopped working after updates MacOS

Hello All, I have a BIG problem. After updating mac os to version 10.9.5, xcode to 6.0.1 and comand line tools to 6.0, QtCreator has stopped working. I can open qtcreator and navigate through my projects. But if I try to build them everything fails. First, it doesn’t find the c++ libraries. I get “<ostream> not found”, “<vector> not found”, etc etc. I’ve solved it adding to the project file “INCLUDEPATH = /usr/include/c+/4.2.1/” before I had “INCLUDEPATH += /usr/include”… But now it fails because it can’t find <OpenGL/gl.h> which is included (# include <OpenGL/gl.h>) in line 102 of qopengl.h…. What is going on??? Any is having the same problems???? Thanks!!!!
