Trying to build test-launch.c for gstreamer but fails to build

Question

I am trying to build test-launch.c on my ubuntu machine (i5) with this command:

gcc -o test-launch test-launch.c `pkg-config --cflags --libs gstreamer-rtsp-server-1.0`

but it fails to build. The error message I see is the following:

test-launch.c:(.text+0x170): undefined reference to `gst_rtsp_media_factory_set_enable_rtcp'

I have already installed

• libgstrtspserver-1.0
• libgstreamer1.0-dev

I am pretty confused and I am wondering if anybody can help me :)

Thank you for reading !

I have the entire build log here.

What version of GStreamer do you have installed? According to the documentation gst_rtsp_media_factory_set_enable_rtcp() is introduced with GStreamer 1.20 which has not yet been released.
