In a header file included ina an app, the following include compiles:
Qt Code: 
  1. #include <QString>
To copy to clipboard, switch view to plain text mode 
In another project, same file, it doesn't.
Error message is "no such file or directory"
However, if i put the full pathname and file in place, it compiles.
Qt Code: 
  1. #include "/usr/local/Qt4/include/Qt/qstring.h"
To copy to clipboard, switch view to plain text mode 

Why ?
