Error when compiling gst-rtsp-server example

  • 772

I'm currently trying to setup a Ubuntu server to redistribute a rtsp feed coming from an ip camera.

I saw that the gst-rtsp-server library of gstreamer could help me with this issue.

I installed the following package:

sudo apt-get install libgstrtspserver-1.0-dev
sudo apt-get install gstreamer1.0-rtsp
sudo apt-get install libglib2.0-dev

I then cloned the gst-rtsp-server library repo on my desktop:

git clone https://github.com/GStreamer/gst-rtsp-server.git

But, when I try to compile a C file (gst-rtsp-server/examples/test-launch.c) given as an example of how to use the library using gcc:

gcc test-launch.c -I/usr/include/gstreamer-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include

I get the following error:

/tmp/ccM7e45N.o: In function `main':
test-launch.c:(.text+0x2e): undefined reference to `g_option_context_new'

test-launch.c:(.text+0x1a6): undefined reference to `g_main_loop_run'
collect2: error: ld returned 1 exit status

There's something I'm missing but I don't know what... ><'

The error is obviously coming from a missing header, but which one and where can I get it?

As always, thanks for the help/tips!

gcc gstreamer rtsp

    If this returns something for you:

    pkg-config --modversion gstreamer-rtsp-server-1.0

    (For me, it returns 1.14.1)

    You can use the following gcc command to compile the wanted example:

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

    P.S. in the command, make sure you use backticks ` and not apostrophes '
