c++ - codelite 5.1 cannot find <QString> -


using codelite 5.1 on ubuntu 12.10:

created minimal qtgui app. built , ran fine. 

#include <qapplication>  #include <qbutton>

were inserted wizard in main.cpp file - no problem. added: 

#include <qstring>

as per qt docs, , pre-processer tells me can't find qstring. checked include setting projects - 

../qt4

and 

../qt4/qt4gui

are there correctly. tried: 

#include <qt4/qstring>

with different case permutations - no go.

what's wrong? (posting on codelite forum).

while qapplication , qbutton part of qt gui module, qstring part of qt core module. gui depends on core, core library linked, that's not problem.

the problem seems include path includes qt top level gui sub-directory. qt's header files structured in modules, 1 directory each module. means <qapplication> , <qbutton> headers in ../qt4/qt4gui , can found compiler.

however, qstring placed in ../qt4/qt4core(1) , has either included #include <qtcore/qstring>(2) in correct module sub-directory, or adding sub-directory include paths in project configuration (recommended), #include <qstring> works too.

(1) think should ../qt4/qtcore, , qt gui ../qt4/qtgui, wrote different in question...

(2) iternally in qt, classes of other modules included this, i.e. relative qt top level include path, if include class uses qstring (qapplication being 1 example), it's working without adding include.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
