Install a package from qt-solutions

Sikarjan

Okay. And this also works if I use the code cross platform? So I can take the files I created on Windows to my Mac and it will also work? If that is so, why do I need to configure and make the files then?

Just tried it on Windows but did not work. I created a folder plugins in my main folder and copied the qtsingleapplicaiton folder there. When I add the path in my pro file I receive an error:

/plugins/qtsingleapplication/config.pri: No such file or directory

This file does not exist. When I try to build my app anyway it fails too:

C:\...\phpPad\plugins\qtsingleapplication\src\qtlocalpeer.cpp:180: Warnung: comparison between 'enum QLocalSocket::LocalSocketState' and 'enum QAbstractSocket::SocketState' [-Wenum-compare]
         if (socket->state() == QAbstractSocket::UnconnectedState) {
                                                 ^

I tried to remove the server/peer functionality since I do not need that but that caused other errors.

Am I facing theses errors because I copied the folder or is this an issue with the code itself and not my fault?

/plugins/qtsingleapplication/config.pri ?

Where exactly did you put that into your project ?

Sikarjan

I do not have it in my project. It is also not provided but required by common.pri:

exists(config.pri):infile(config.pri, SOLUTIONS_LIBRARY, yes): CONFIG += qtsingleapplication-uselib

The common.pri file is required by qtsingleapplication.pri:

include(../common.pri)

SGaist

Can you share your .pro file ?

Sikarjan

Sure I can:

I believe the issue is with the client/peer feature. This feature is not relevant for me. Somewhere in the documentation I read the the minimal example is not making use of this feature but it uses the same files. So I don't get how they did it.

What did you copy exactly from the QtSolutions module ?

Sikarjan

Currently I am trying all of this only on Windows.

I downloaded the entire solutions package from github as zip. Extracted it in my Downloads folder and followed the install instruction within the qtsingleapplicaition folder. Then I copied the entire qtsingeapplication folder and pasted it in the plugin folder which is in my root folder. From the qtsingleapplication folder I removed the configure, make, docs and examples. The src and buildlib folder is untouched.

This is the content of my qtsingeapplication folder

buildlib
src
common.pri
qtsingleapplication.pro

SGaist

Where is your project source located on your machine ?
Same question for QtSolution sources.

Sikarjan

On Windows my files are in my standard Windows documents folder. On OS X under User/Programming. The qtsingleapplication folder is in the project folder under plugins. The rest of the QtSolution files is still in my Download folder.

SGaist

AFAIR you should essentially need:

INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD
QT *= network
greaterThan(QT_MAJOR_VERSION, 4): QT *= widgets

SOURCES += $$PWD/qtsingleapplication.cpp $$PWD/qtlocalpeer.cpp
HEADERS += $$PWD/qtsingleapplication.h $$PWD/qtlocalpeer.h

jsulm

@SGaist += not *=
:-)

@jsulm said in Install a package from qt-solutions:

@SGaist += not *=
:-)

*= is perfectly fine. See the docs

jsulm

@sierdzio Oh, good to know :-)
Thanks!

Sikarjan

Thanks for all you help and time. I got it working finally. Probably not the most elegant way but it works for me =)

@SGaist your suggestion worked (after I figured out to remove the include statement) but it included the files directly into my project messing up my structure in Creator. Also it gave me an error in my main.cpp on #include <qtsingleapplication.h> no such file

Essentially only the network module was missing.

QT       += core gui xml network

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = phpPad
TEMPLATE = app

include(plugins/qtsingleapplication/src/qtsingleapplication.pri)

I am very sure that I tried to include that before with a clean and rebuild. No idea why it is working now.
