[SOLVED] Variable GST_VERSION is not defined.

[Zola]

I am trying to build multimedia package with i386 qmake from qt-opensource-linux-x86-5.5.1.run on Ubuntu 14.04.3 and I get the following error:

Variable GST_VERSION is not defined.

libgstreamer packages are installed on Ubuntu, but still getting that error.

Did you install the development packages for GStreamer?

[Zola]

yes @jsulm, with command: sudo apt-get install gstreamer*

[Zola]

I passed that error with running qmake:

/usr/local/Qt-5.5.0/bin/qmake GST_VERSION=1.0

but now I am getting following error:

qgstreameraudioinputselector.cpp:42:28: fatal error: alsa/asoundlib.h: No such file or directory
#include <alsa/asoundlib.h>

compilation terminated.

You need alsa developer package - probably libasound2-dev

@Zola said:

alsa/asoundlib.h: No such file or directory

Yes @jsulm

QtMultimedia package depends in this situation on two packages, so solution will be:

sudo apt-get install gstreamer* libasound2-dev
