QMediaPlayer::ServiceMissingError

Hi,

Qt 5.5, as Qt 5.7 is not packaged for Linux on 32 bits Intel.

There is a Ubuntu package called 'gir1.2-gstreamer-1.0', which says 'Description: GObject introspection data for the GStreamer library', and its version is '1.8.1-1~ubuntu1'.

Thanks!

AFAIK, Qt 5.5 uses GStreamer 0.10. So you can either install that version (plus plugins) or rebuild the QtMultimedia plugins against your installed GStreamer version.

So, the 'gstreamer' I have installed is newer than the Qt 5.5 requires, right? If so, shouldn't it work?

Do you think it will work on Qt 5.7?

Thanks!

SGaist

In this case not because it's a new major release (1.0 vs 0.1). That's why the plugin doesn't load.

Since you'll be building Qt 5.7 by hand, it will pickup the your installed GStreamer and build the plugin accordingly.

Changing the subject to 5.7, I run 'configure', 'make' and 'sudo make install', but I did not find 'qtcreator' anywhere in the directory tree, and it is not in the $PATH. Does 'qtcreator' come in the tar.gz Qt 5.7 package?

Thanks!

SGaist

No, Qt Creator is a younger and independent project. However you don't have to build it yourself (unless your current Qt Creator is really old).

Qt Creator can handle older as well as newer version of Qt.

Just checking, I need to change 'Tools/Options/Build & Run/Qt Versions', to use Qt 5.7 libs, right?

Thanks!

SGaist

Add your self built 5.7 to the Qt Versions and then create a new Kit using it. Then you'll be able to configure and build your project with that Kit.

'make -j4' run for about an hour now, and finished with

'Makefile:77: recipe for target 'module-qtbase-make_first' failed

Before running 'make', I run './configure -help' and I did not see anything related to module 'qtbase'. Any ideia on what I missed?

Thanks

canellas

I think I found the answer at https://bbs.archlinux.org/viewtopic.php?id=191765. Well, if it works, it'll take about an hour for 'make' to run again. It's 9:30 p.m. here, so maybe I'll only have news tomorrow.

Thanks again!

SGaist

Did you add the -developer-build option ? If so you should drop it unless you plan to hack on Qt itself.

canellas

In my first attempt, I used it, but then I tried

./configure -no-warnings-are-errors -gstreamer 1.0 -prefix /usr/local/Qt-5.7 -debug

and I got the same error...

I saw somewhere someone tried with '-release -force-debug-info'. I'll try that, and let you know later.

Thanks

SGaist,

Thanks a lot for your help, but due to time restrictions, I gave up on installing 5.7 on a Linux on a 32 bits CPU.

I am using a Mac OS 64 bits at work now.

Thanks a lot for your help.
