error : undefined reference to `qt_resourceFeatureZlib'

Yes, i mean;
Maybe problem can be about file association . I wanted to point this out .
It's like it can't see the libraries and therefore cannot mount sub-directories.
AM i wrong? -

AM i wrong?@sberkantgulen Not sure what you mean. QtCreator has nothing to do with building of your app (you can build in a terminal without QtCreator). Also, nothing is mounted. The problem is that linker can't find the libraries. That means those libraries are not located in the folders you pass to the linker (like here: -L/home/kkvyz1/Desktop/dQGCS/dev/build-YKI-Desktop_Qt_5_14_2_GCC_64bit-Debug/PL/../DL). So, I suggest you really take a look at the link I gave you and define the dependencies between your subfolders properly.

I mean, my problem can be like this topic:
https://forum.qt.io/topic/107933/undefined-reference-to-qt_resourcefeaturezlibAnd i don't know how can i change libraries.

@sberkantgulen The problem from your last compile log has nothing to do with resourcefeaturezlib...

You are right. I built my project step by step. And i added every code block line by line.
Problem is about gstreamer.
PKGCONFIG += gstreamer-1.0 gstreamer-video-1.0 #Qt5GStreamer-1.0 #Qt5GStreamerQuick-1.0When i add this line there is no error in my project.
But i uncomment 2 packages which are #Qt5GStreamer-1.0 #Qt5GStreamerQuick-1.0 , and they cause an error.PKGCONFIG += gstreamer-1.0 gstreamer-video-1.0 Qt5GStreamer-1.0 Qt5GStreamerQuick-1.0Probably qt can't find the path for gstreamer.

Hi,
Might be a silly question but did you install the corresponding development packages ?
-
Of course,
Maybe i coludn't explain properly.
When i install qt from terminal (Default Qt 5.9 for Ubuntu 18.04) and install packages, everything is ok.
When i install qt from offline source (Qt 5.12 or Qt 5.14) and install same package like above, qt can't see same libraries.
When i install qt from terminal (Default Qt 5.12 for Ubuntu 20.04) and install packages, everything is ok again.So, i think the problem is about path or something else about location on system.
Maybe additional settings are required for offline installation but i couldn't find anything....

@sberkantgulen The question was: did you install development packages for GStreamer?

Yes, In all 3 cases I installed all required packages the same way. Gstreamer and everything else.

To make sure the is no misunderstanding: @SGaist was asking about GStreamer development packages (those have -dev postfic). Did you install those? Can you show which exact GStreamer packages are installed?

My packages for gstreamer:
sudo apt-get install --reinstall libxcb-xinerama0
sudo apt-get install -y libqt5gstreamerquick-1.0-0
sudo apt-get install -y libcairo2-dev
sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio
sudo apt-get install libgstreamer-plugins-base1.0-d
sudo apt-get install libqt5gstreamer-dev
sudo apt-get install libgstreamer1.0-dev
sudo apt-get install libgstreamer-plugins-base1.0-d
sudo apt-get install libgstreamermm-1.0-dev
sudo apt-get install qtdeclarative5-devAnd i could see packages in both path which are;
"/usr/lib/x86_64-linux-gnu/" and "/usr/lib/x86_64-linux-gnu/pkgconfig/"
After these installations i can run my program if i install from terminal with commands:
sudo apt install build-essential
sudo apt install qtcreator
sudo apt install qt5-defaultBut i can't run program if i install from offline source. Really i can't understand the difference.
