Qt5 (How to install an addon/ module like Qt Location for instance)

[jraichouni]

Hello dear all!

I installed QtSDk 5.0.1 under Ubuntu this evening and the maintanance tool provides "Remove all components" only.

I would like to add the add-on/ module Qt Location to my Qt5 installation.

---

Tried to build/ install it from source (cloned from git://gitorious.org/qt/qtlocation.git). qtlocation seems to depend on qt-quick3d.
How do I have to proceed to build and install all (incl. docs, imports etc.) into the tree under $QTDIR?

Tried:
git clone git://gitorious.org/qt/qtlocation.git
cd qtlocation
sudo which qmake
sudo make sub-src-qmake_all
sudo make install

But I had no success.

Hope to find some help here!

Best regards from Hamburg

Note that the latest Qt 3D and Qt Location may not build against Qt 5.0.x. You may need to use Qt 5.1.x

Clone and build Qt 3D

git clone git://gitorious.org/qt/qt3d.git
cd qt3d
qmake # from qt5
make
make docs
sudo make install

Clone and build Qt Location
git clone git://gitorious.org/qt/qtlocation.git
cd qtlocation
qmake # from qt5
make
make docs
sudo make install

Wow, what a quick reply!

I'm going to re-try the build of the latest Qt5 sources tomorrow.
Is it possible to implement/ consider any of the accepted additional modules
during the build process of qt itself?

Like:
git clone git://gitorious.org/qt/qt5.git
(cd qt5/.../ here?)
git clone git://gitorious.org/qt/qt3d.git
git clone git://gitorious.org/qt/qtlocation.git

And then
cd qt5
./configure (...) # consider additional modules here??
make -j X
make install

[amccarthy]

Yes that is possible. Add the clones as you did above then you need to add those modules to the qt.pro file.

Hi amccarthy

bq. you need to add those modules to the qt.pro file.

How do I do that?

I tried it by adding
@
addModule(qt3d, qtbase)
addModule(qt-quick3d, qtbase, qt3d, qtdeclarative)
addModule(qtlocation, qtbase, qt3d, qt-quick3d, qtdeclarative)
@

to qt.pro

I ran
@
qtbase/bin/qmake -recursive;
make -j 5 all;
@
then.

Another question:

I added
@
[submodule "qt3d"]
path = qt3d
url = git://gitorious.org/qt/qt3d.git
[submodule "qt-quick3d"]
path = qt-quick3d
url = git://gitorious.org/qt-quick3d/qt-quick3d.git
[submodule "qtlocation"]
path = qtlocation
url = git://gitorious.org/qt/qtlocation.git
@

to the file .gitmodules and ran
@
perl init-repository
@

But it had no effect!?

I needed to clone the additional modules manually like described above. Any ideas?

Best regards

init-repository wont reinitialise the repo. IIRC it checks if qtbase has been cloned and aborts. Unless you pass the -f flag. I suggest

@init-repository --no-update -f@

which will clone new submodules and not touch existing submodules. Or just clone manually.

The qt-quick3d module is not required. It was the old name for qt3d.

Your addModule syntax is wrong. The dependency arguments are a space separated list. You want something like:

@addModule(qtlocation, qtbase, qtdeclarative qt3d)@

Hi!

Thanks for your advice!

Going to try that these days.
I think there is a cookbook for the whole procedure of
building and installing Qt (incl. an example use of add-on module(s), build/ install docs, build/ install qtcreator) needed.

I have not enough knowledge, to write something like that.

But a description for a setup of a complete (e.g. example, on implementing an add-on) and up-to-date Qt development environment would help other too.

The description under "Building Qt 5 from Git":http://qt-project.org/wiki/Building_Qt_5_from_Git is not really complete but could be a good starting point, as different platforms are considered.

My bash snippets to perform all steps are a result of try/ error/ re-try success.

What commit id was used to compile QtLocation and which exact Qt vesion was used ? I don't get it compiled with Qt 5.1.1 ???

[jraichouni]

Hi!

I successfully compiled Qt 5.0.1 (including QtLocation) on 64-bit Ubuntu Linux machine
and wrote a small recipe of all steps.

Hi Joomie,

thanks for the reply, i'm interested in your procedure. Could you send me the file please, Skype-user : valckewim

I could already compile QtLocation for Qt 5.2.0 beta, but there are still issues with this Qt so i wanna try Qt 5.0.1 together with your instructions.

Best regards,

Wim.
