Help installing Qt Location

sandybisaria

I have downloaded Qt Location from the website but am unsure where to go from here. How do I add the module to Qt?

JKSH

Hi,

Which feature of Qt Location are you looking for?

Qt Location has not been released yet. A small part of it has been split off into the Qt Positioning module: http://doc-snapshot.qt-project.org/qt5-stable/location-positioning-cpp.html -- this module will be released in Qt 5.2. You can use it by installing the "Qt 5.2 beta":http://download.qt-project.org/development_releases/qt/5.2/5.2.0-beta1/

I am looking for the Positioning API. I'll try using Qt 5.2 beta.

I'm trying to test the weatherinfo example, and it doesn't seem to be able to find my location.

JKSH

Do you have GPS plugged in, and drivers installed? Note: That example only shows 4 cities: Brisbane, Oslo, Helsinki, and New York

sandybisaria

No, but I have found an alternative solution that does not need Qt Location. But thanks for the advice anyway.

Hi!

Just installed "Qt 5.2.0 beta 1":http://download.qt-project.org/development_releases/qt/5.2/5.2.0-beta1/qt-mac-opensource-5.2.0-beta1-clang-offline.dmg but it is not possible to perform

@import QtLocation 5.0@

in a qml file.
What preparation is needed to be able to use QtLocation in Qt 5.2?
Is it going to be accessible without any build from source steps, therefore integrated in the complete framework downloads for a desired target system!?

I needed to manually consider the submodules (e.g. qt3d and qtlocation) before build from source process for Qt 5.0.1 to use QtLocation. This was really time-consuming and is currently not possible (see below).

Best regards
jraichouni

P.S.
The build of 5.2.0 on OSX 10.9 (Mavericks) does currently not work as OSX 10.9 is currently unsupported (mkspec) and crashes after hacking this hard coded limitation for the OSX version for instance.

But is a build from source needed to use QtLocation in Qt5.2.0?

JKSH

Hi jraichouni,

Qt Location and Qt 3D have not been released yet, and will not be part of Qt 5.2 either. If you want those, you'll need to build them yourself.

Only Qt Positioning will be released in Qt 5.2.

For Mavericks, try the Release Candidate candidate (not a typo): http://download.qt-project.org/snapshots/qt/5.2/5.2.0-rc1/2013-11-26_172/

Hi JKSH!

Thanks for your quick reply!

I am going to try the build of the release candidate.

Do you know, why QtLocation is not going to be part of Qt 5.2?

Is there any documentation for the needed steps to build non-standard submodules into the framework?
I have in mind, that there was something like

git clone the submodule(s)
Edit the file .gitmodules
Step into the sumodule(s) directories to explicetly perform make all for each of the modules etc.

It would help to find any explanation of the exact process needed to completely integrate additional available submodules being not considered in the default build configuration.

Best regards from Germany

You're welcome. :)

Qt Location is not going to be part of Qt 5.2 because the module is not ready yet. It still needs to be polished to reach a good quality before it is released. The same goes to other modules like Qt 3D, Qt Versit, Qt JSON DB, etc.

These modules were polished and released as part Qt 5.2: Qt NFC, Qt Bluetooth, Qt Positioning, Qt Windows Extras, Qt Mac Extras, Qt Android Extras.

Which part of Qt Location do you want? Is "Qt Positioning":http://doc-snapshot.qt-project.org/qt5-stable/qtpositioning-index.html enough? If so, you don't need to build anything -- just install Qt 5.2

Are you sure?
I am using Qt 5.2 stable snapshot 9th December and even positioning module is valid, it doesn't create a valid QGeoPositionSource...

JKSH

Hi AlterX,

What platform are you running? Qt Positioning isn't supported on Android yet: http://www.kdab.com/qt-on-android-episode-1/

If it's another platform, do you have the GPS hardware connected and appropriate drivers installed?

AlterX

I know it's not yet supported on Android...I had to rebuilt positioning by myself.

Hi!

Currently I have Qt5.2.0 installed on OSX.

My try to build QtLocation fails :-(

My proceeding:

Install binaries and sources of Qt5.2.0
cd into $QTDIR/../Src
git clone git://gitorious.org/qt/qtlocation.git
cd qtlocation
qmake -r
make -j 4 all

make ends up with the following error:
@In file included from positionpollfactory.cpp:42:
./positionpollfactory.h:46:10: fatal error: 'QGeoPositionInfoSourceFactory' file not found
#include <QGeoPositionInfoSourceFactory>
^@

It would be great to get an explanation on how to build QtLocation!

Cheers

Hi!

I tried that without success:

Open /Users/jamil/Qt5.2.0/5.2.0/Src/qtlocation/qtlocation.pro in Qt Creator
Run Build -> Run qmake (exits normally)
Run Build -> Build project "qtlocation"

No. 3) Outputs:

It would be great to get a small step by step explanation like:

Download and install Qt5.2.0 including the sources
Change into directory ~/Qt5.2.0/5.2.0/Src/qtlocation
Run qmake -r -spec macx-clang CONFIG+=x86_64
Run make

Reger to my next post on the next page! (had to Split it because of ist length)

jraichouni

I tried is:

cd into ~/Qt5.2.0/5.2.0/Src
mv qtlocation qtlocation.bak
git clone git://gitorious.org/qt/qtlocation.git
cd qtlocation
qmake -r -spec macs-clang CONFIG+=x86_64
make

It fails:

Every try ends up in a different error and I do not have any idea what I should do
to get qtlocation being built!?
