QFileSystemWatcher's signal "directoryChanged" not emitted
-
@VRonin do you know how to get the version 5.6.2 of qtbase from code.qt.io with git? (to build it in debug and try to debug corelib)
-
@VRonin ok thanks vronin...
-
@VRonin it is done.but to debug qfilesystemwatcher should I open corelib.pro in QtCreator (QtCore) and build it debug and put breakpoints and attach to my app synchro ?
-
@VRonin I want to put a breakpoint l.364 of QFileSystemWatcher_win.cpp and watch error l365
-
@VRonin there is "attach to unstarted application" and "debug an external application" in Qtcreator\debug. is it possible to use one this option to debug QtCore (corelib) with my app synchro.exe ?
-
@VRonin when building corelib I have this error ..\corelib\global\qt_pch.h:50:21: fatal error: qglobal.h: No such file or directory
#include <qglobal.h>
qglobal.h is in the directory but I think I lacks an environment variable ? -
@VRonin OK I think I have found : I have copied the directory include of the source single (.zip) of 5.6.2 in the direcorty qtbase and I have put in my environment variable INCLUDE the path of directory include and reboot my windows...I think it will be ok

I have put
INCLUDEPATH +="../../include"
INCLUDEPATH +="../../include/QtCore"int he corelib.pro but I have an error In file included from ..\corelib\animation\qabstractanimation.cpp:143:0:
..\corelib\animation\qabstractanimation_p.h:52:31: fatal error: private/qobject_p.h: No such file or directory

#include <private/qobject_p.h>It think I will build the whole Qtbase as usually and then open the corelib.pro and put the directory of lib QtCored.dll as build directory and try to debug with my exe (synchro.exe)

You have to, qtbase, unlike the other modules, requires that you run configure before building it.

@SGaist even after done configure,if I want to debug qtcore (corelib) in Qtcreator,it needs to be build with Qtcreator and I can't build it with Qtcreator (mingw).so I can't debug corelib (qtcore) and I don't know how to do.I have built qtbase with command line but it is unuseful...
-
What problem do you get building from the command line ?
-
@SGaist I have added INCLUDEPATH +="../../include"
INCLUDEPATH +="../../include/QtCore"
in the corelib.pro because I had errors on include paths but I have still errors on other include paths:
In file included from C:\qtsrc\qtbase\src\corelib\animation\qabstractanimation.cpp:143:0:
C:\qtsrc\qtbase\src\corelib\animation\qabstractanimation_p.h:52:31: fatal error: private/qobject_p.h: No such file or directory
#include <private/qobject_p.h>

You have to build qtbase from the command line. There's a lot of stuff happening during the build phase of qtbase like header generation. Therefore, build it once and then start hacking on it.

@SGaist I have built QTbase with command line without problem.But to debug QtCore with QtCreator I must build it with QtCreator.
-
@SGaist these problems are only for building with QTCreator.I have no problem to build with command line.but to debug QTCore in QTcreator I must build with QTcreator
@stephane78 Your assumption is wrong: you don't have to build with QtCreator to be able to debug in QtCreator. You just need to build a debug version.

@jsulm how to debug then ? I have a debug version of Qtbase and I have put the build directory where is the debug version but when I click on the debug button in Qtcreator it tries to build the project....

@stephane78 To debug QtBase you need a project which is linked against it - you cannot execute a library, so you need an executable. Create a project write some code which uses QtBase, put a break point and start debugging. You then can step into QtBase code.
