How to create directories??

[jacek]

Is there a way to create the folders by some functions in the code or I have to create them by mean of the MakeFile?

Use QDir::mkdir() or QDir::mkpath().

If yes what I've to add to the makefile generated with qmake.I tried with something like:

It should be:

directoryName:
       $(MKDIR) directoryName

directoryName:
       $(MKDIR) directoryName

To copy to clipboard, switch view to plain text mode 

You also have to add "directoryName" somewhere as a dependency. Like:

all: ... directoryName ...
       ...

all: ... directoryName ...
       ...

To copy to clipboard, switch view to plain text mode 

But remember that qmake will overwrite your Makefile.
