Where is Qt Quick Compiler (for enterpise edition src)?
I downloaded the evaluation version of Qt 5.3.2 Enterprise edition and the binary installed version of Qt Quick Compiler works (verified with debug message) and Qt5QuickCompilerRuntime.dll exists.
Now I want to build Qt from src for static linking but after building there is no Qt5QuickCompilerRuntime and I cannot find any source code that would build this component? I tried manually copying the installed binary to the static build Qt but it didn’t work. Does Digia not include Src for Enterprise Add-ons?
btw my goal is to create the fastest starting QML app so my plan is to: – use qt quick compiler (I assume only in enterprise edition) – static link Qt/QML (so have to build from src) – remove un-needed large Qt components (icu, webkit etc.)

Qt Creator won't compile with boost
Hey there, I’m trying to use boost in a qt project (archives and serialization), but when i write “#include <boost/serialization>”, even if my qt creator detects the files (it displays the list of files i may include) the compiler will keep saying that there is no such file or directory. I’m using qt creator 5.3.2 with msvc 2013, and i added the lines “ INCLUDEPATH += pathtoboost”
And “LIBS += -Lpathtoboost”
What have i done that is not right?

Permission denied
Hi All,
I’m attempting to setup a tool chain so I can create and debug applications on a Beaglebone Black and I’m having some troubles with Qt Creator. My host machine is Ubuntu 12.04 running on VirtualBox 4.3. I used the procedure outlined on http://embedded.von-kannen.net/ to download, configure, and build QtCreator. For the most part everything well until I got to the part were Qt was being installed into* /opt/qt-arm *and I got a permission error. It wouldn’t allow me to to make the qt-arm folder and subfolders in /opt. No problem, I just prepended “sudo make” and everything appears to have worked fine.
I was able to start Qt Creator and make a simple Hello World app. The problem is, when I goto build the app. I get a “execvp: /opt/qt-arm/bin/uic: Permission denied” message. I’m not sure what to do next.
Regards,

Another static library issue.
I followed this guide for creating and using a static library in Qt:
https://qt-project.org/wiki/How_to_create_a_library_with_Qt_and_use_it_in_an_application
I have a class that I would like to use in Matlab, so I would like to create a static library. I am using Qt 4.8.0, statically compiled, commercial on a Windows 7 machine.
I created a project for the library:
QT += network
TEMPLATE = lib
CONFIG+= staticlib
# Input
INCLUDEPATH += ../common/output \
../common/input \
../common/core \
../common/crc
HEADERS += ../common/output/imageUdpSender.h \
../common/input/image.h \
../common/core/coreModule.h \
../common/input/internalProtocol.h\
../common/output/testState.h \
../common/crc/crc.h
SOURCES += ../common/output/imageUdpSender.cpp \
../common/core/coreModule.cpp \
../common/output/testState.cpp \
../common/crc/crc.cpp
INTF_VERSION = 2
INTF_VERSTR = '\\"$${INTF_VERSION}\\"'
DEFINES += INTERFACE_VERSION=\"$${INTF_VERSTR}\"
TARGET = ../../../ShutterSoftware/build/Library
static { # everything below takes effect with CONFIG += static
TARGET = ../../../../../ShutterSoftware/build/static/Library
CONFIG += static
QTPLUGIN += qsvg qico #qpng # image formats
DEFINES += STATIC
message("~~~ static build ~~~") # this is for information, that the static build is done
mac: TARGET = $$join(TARGET,,static,_static) #this adds an _static in the end, so you can seperate static build from non static build
win32: TARGET = $$join(TARGET,,static,s) #this adds an s in the end, so you can seperate static build from non static build
}
The above project creates a *.lib. However, when I tried to include it in a project, I get this error:
C:\Users\IKOMED6\Documents\SVN\Software\ShutterControlGUI\Qt\ShutterSoftware\ShutterUILibrary\TestLibrary\main.cpp:2: error: C1083: Cannot open include file: 'imageUdpSender.h': No such file or directory
The project file for the project trying to use the library:
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = TestLibrary
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h
FORMS += mainwindow.ui
INCLUDEPATH += $$PWD/../../build/static
LIBS += -static -L$$PWD/../../build/static/ -lLibrarys.lib
TARGET = ../../../ShutterSoftware/build/TestLibrary
static { # everything below takes effect with CONFIG += static
TARGET = ../../../../../ShutterSoftware/build/static/TestLibrary
CONFIG += static
QTPLUGIN += qsvg qico #qpng # image formats
DEFINES += STATIC
message("~~~ static build ~~~") # this is for information, that the static build is done
mac: TARGET = $$join(TARGET,,static,_static) #this adds an _static in the end, so you can seperate static build from non static build
win32: TARGET = $$join(TARGET,,static,s) #this adds an s in the end, so you can seperate static build from non static build
}
and the main.cpp is extremely simple (I only made this project to test the .lib):
#include "mainwindow.h"
#include "imageUdpSender.h"
int main(int argc, char *argv[])
{
}
I’m not sure what is wrong… how do I even know if the *.lib was created properly? I’ve tried everything I’ve found online, so I’m at a loss…
Thanks in advance.

Debug in MAC OsX10.9
Hi,
I try to debug an external application.
Everything is going well, compile right, macdeployqt works fine, but I have one problem…
The application show me this error:
QSqlDatabase: QMYSQL3 driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC3 QODBC QPSQL7 QPSQL
When I read forums about this problem, everybody talk about libqsqlmysql.dylib in Qt/plugins/sqldrivers, but in this folder I only have:
libssqlite.dylib
libqssqlobdc.dylib
libqsqlpslql.dylib
I use QT4.8. (Qt libraries 4.8.6 for Mac (185 MB) (Info) and debug libraries (476 MB) both installed)
Also in my computer I have installed Qt 5.0.2 and I have the same libraries in its respective plugin folder.
What is my error?

no member named 'addAction' in 'QWidget'
I downloaded Qt package including Qt Creator from the official website and started to create a simple project with mainwindow.cpp, mainwindow.h and mainwindow.ui in. Then I hit the build button. It pops out the same errors:
qmenu.h:86:20: error: no member named ‘addAction’ in ‘QWidget’
This error seems to point to the file below with the error line
Qt/5.3/clang_64/lib/QtWidgets.framework/Versions/5/Headers/qmenubar.h:71:20: error: no member named ‘addAction’ in ‘QWidget’
using QWidget::addAction;
Could somebody tell me what is going on here? I use the cmake to do the same process, the same error pops out, is it a bug or not?
PLUS: I am using Qt Creator on MAC OS Mavericks.
Cheers,

Forward Declaration in a Static Library
Hello,
I am trying to compile a static library to use with a non-Qt application. I wish to create a wrapper in this library to minimize the number of includes the final static library needs.
These are the basics of the code:
//libraryWrapper.h
class ImageSender; //forward declaration
class LibraryWrapper{
public:
LibraryWrapper();
~LibraryWrapper();
private:
ImageSender* _sender;
}
The library source file is:
//LibraryWrapper.cpp
#include "LibraryWrapper.h"
#include "imagesender.h"
LibraryWrapper::LibraryWrapper(){
_sender = new ImageSender();
}
~ImageSender(){
//delete _sender;
}
I successfully compile this and can link to it in my non-qt project. If I comment out _sender = new ImageSender(); (line 6 in LibraryWrapper.cpp), I do not get any errors when I compile and run the non-qt application.
//LibraryWrapper.pro
QT += network
QT -= gui
TEMPLATE = lib
CONFIG += staticlib
HEADERS += imageudpsenderwrapper.h \
SOURCES += imageudpsenderwrapper.cpp \
TARGET = ../../../ShutterSoftware/build/ImageUdpSenderLibrary
The only thing I can think of is adding imagesender.h to the HEADERS += in the .pro file, but when I do this it asks for its dependencies, which I think defeats the purpose of the forward declaration….
Just to show the application linking to the static library:
#include "stdafx.h"
#include "imageudpsenderwrapper.h"
using namespace System;
int main(array<System::String ^> ^args)
{
ImageUdpSenderWrapper* _sender = new ImageUdpSenderWrapper();
return 0;
}
Thanks!

Qt 5.x dynamically for iOS with SSL support (QSslSocket)
Hi,
i read several threads about iOS and SSL support.
I just want to clearify my understanding (or misunderstanding) about the situation concerning iOS and SSL support for Qt 5.x.
The only way to use SSL with iOS until now is to use a static Qt build, right?
Is something iOS / SSL related planned for the 5.4 release?
If static build is the only way for iOS, is it ok to use the Indie Mobile license to use the static build Qt?
Maybe there is nother way to get it running on iOS?
Greetings

Deploy Step Failed
Hi All,
I want to learn how to use Qt on the Beaglebone Black. I used the steps outlined on “embedded.von-kannen.net”. I created a vm using the recommended version of lubuntu and followed all of the instructions to download and build Qt Creator and install Qt on the BBB. I was having great success and able to build a simple Helloworld app. I setup the debugger and it reported that it could connect to the target( the BBB ). Then the issue.
I tried to deploy the app to the target and got the following error: “The remote file system has 0 megabytes of free space, but 5 megabyte are required” . When I examine the BBB using “free -m” it reports that I have 372 megabytes of free space available.
Is there some process that should be running on the BBB and if so what is it?

Project is using QMYSQL3 instead of QMYSQL?
I am having troubles retrieving results from a UNION query, it appears that someone else has had this issue in the past (http://permalink.gmane.org/gmane.comp.lib.qt.general/31200). I am not sure why it is loading QMYSQL3 but the link suggested that unions are not supported in QMYSQL3, is this true? I can substitute my query with any non-union query and it works fine, so the rest of the prepare/bind/execute code must be fine.. I have tried building from source as well as using the binary repositories, but neither fix my issue…
QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL", "connection1");
db.setHostName("-----");
db.setUserName("-----");
db.setPassword("-----");
db.setPort(3306);
db.setDatabaseName("-----");
QSqlQuery query = QSqlQuery(db);
query.prepare("*large query with 1 UNION ALL*)");
query.addBindValue(98);
