@Julio Hi, and welcome to the Qt forum! Could you please make a screenshot, just to make sure we're talking about the same menus. (You can post an image for example at http://postimage.org/ and then include it here with ![](image-url).)

Thank you
I realized that when I try to create a new project does not appear classes
link text

I do not know if it's related, but I did a project and work normal, but when I use the library <limits > appeared this error
link text

On my machine the list is also empty but only when I click the "New project" button on the "Welcome" page. It works as expected when I click "File" -> "New File or Project..." in the main menu.

ah ok ..
here it is so ..
How can I resolve the error: QMAKE_LFLAGS_EXCEPTIONS_ON: No such file or directory
link text
it does not recognize <limits >

@Julio The problem is not limits.
Did you put QMAKE_LFLAGS_EXCEPTIONS_ON in your pro file?
Can you post the content of your pro file?

Hi,
Pro file is link text

You should not use QMAKE_CXXFLAGS to activate C++11, do it this way:
CONFIG += c++11

Except from that it looks OK. What is the content of the Makefile?

[Julio]

I did a test
and this error appears just when I create a new project and command run. Even if I do not put anything
