Hello all.

Following the code checkout procedure outlined here: marble.kde.org/sources.php .

Marble compilation fails on Qt5. Is work being done on making Marble compatible with Qt5?

While I do not know about the Qt only version of Marble, the KDE version of Marble uses kdelibs, which is still being ported to Qt 5 as part of the KDE Frameworks effort.

We have a qt5 branch now with ongoing work to support Qt 5. See also viewtopic.php?f=217&t=112088

Any update on Marble/QT5 compatibility? I got the latest GIT repository today and it didn't work, but it seems like it is mostly ready looking at the git history. Or am I doing something wrong?

Currently you need to use the qt5 branch and invoke cmake like this:

cmake <srcdir> -DQTONLY=1 -DQT5BUILD=1

Hi,
I'm new to Marble and KDE, and I also need to use Marble with Qt5. Have anyone had any success with building and installing for Qt5?
mzanetti; I can't seem to find that branch, could you please provide a link or point me in the right direction?
Thanks

git clone git://anongit.kde.org/marble.git
cd marble
git checkout qt5

I received the following errors while trying to build with Qt5:

C:\source\libs\Marble_Qt5\marble>cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=C:\source\libs\Marble_Qt5\marble-build -DQTONLY=TRUE -DQT5BUILD
=TRUE
CMake Error at src/CMakeLists.txt:23 (STRING):

Which version of CMake are you using? You might need to update to a newer version of CMake, which supports the syntax Marble is using there.

I guess qmake is still version 4 on your system. When running

Code: Select all

qmake -v

which version does it report?

QMake version 3.0
Using Qt version 5.1.1 in C:/source/libs/QtCommercial/QtCommercial5.1.1/5.1.1/qtbase/lib

cmake version 2.8.11.2

I'm not familiar with cmake, perhaps I made a mistake in the syntax?

The command you used to run CMake was fine - what is likely is that the syntax within the CMakeLists.txt file is newer than that supported by the version of CMake you are using. If you update to a newer version, this problem should hopefully be resolved.

I updated cmake from version 2.8.11.2 to 2.8.12, which seems to be the latest one available.
Then I did a clean git clone + git checkout qt5
I still get the same error :
C:\source\libs\marble>cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=C:\source\libs\marble_build -DQTONLY=1 -DQT5BUILD=1
CMake Error at src/CMakeLists.txt:23 (STRING):

I have now verified this on a build node for the KDE Continuous Integration system. Please report the build failure to the Marble development mailing list (marble-devel@kde.org) so this can be corrected. It appears later versions of CMake have changed their compatibility - preventing the existing CMake code from working.
