qconf is supposed to work with Qt4 and Qt5, but since commitc4f7398bee("kconfig: qconf: make debug links work again"), building with Qt4 fails as follows: HOSTCXX scripts/kconfig/qconf.o scripts/kconfig/qconf.cc: In member function ‘void ConfigInfoView::clicked(const QUrl&)’: scripts/kconfig/qconf.cc:1241:3: error: ‘qInfo’ was not declared in this scope; did you mean ‘setInfo’? 1241 | qInfo() << "Clicked link is empty"; | ^~~~~ | setInfo scripts/kconfig/qconf.cc:1254:3: error: ‘qInfo’ was not declared in this scope; did you mean ‘setInfo’? 1254 | qInfo() << "Clicked symbol is invalid:" << data; | ^~~~~ | setInfo make[1]: *** [scripts/Makefile.host:129: scripts/kconfig/qconf.o] Error 1 make: *** [Makefile:606: xconfig] Error 2 qInfo() does not exist in Qt4. In my understanding, these call-sites should be unreachable. Perhaps, qWarning(), assertion, or something is better, but qInfo() is not the right one to use here, I think.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
