Gst RTSP server programming

I've installed gst-rtsp-server and I wanted to try a simple code. But on compilation I'm getting the following error: 

In function `main':
test-launch01.c:(.text+0x64): undefined reference to `gst_rtsp_server_new'
test-launch01.c:(.text+0x74): undefined reference to `gst_rtsp_server_get_media_mapping'
test-launch01.c:(.text+0x7d): undefined reference to `gst_rtsp_media_factory_new'
test-launch01.c:(.text+0x95): undefined reference to `gst_rtsp_media_factory_set_shared'
test-launch01.c:(.text+0xad): undefined reference to `gst_rtsp_media_factory_set_launch'
test-launch01.c:(.text+0xc9): undefined reference to `gst_rtsp_media_mapping_add_factory'
test-launch01.c:(.text+0xe9): undefined reference to `gst_rtsp_server_attach'
collect2: ld returned 1 exit status

I've included the two headers. What am I missing?

Initially I was using the below command to compile when I also got similar errors

gcc -Wall test-server.c -o test-server $(pkg-config --cflags --libs gstreamer-1.0)

After reading comments above, it looked like not linking to gstreamer-rtsp-server-1.0 lib was the issue so I changed the command as below

gcc -Wall test-server.c -o test-server $(pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0)

NOTE: My build environment is Ubuntu 19.04

After running

apt-get install libgstrtspserver-0.10-dev

the command

pkg-config --libs gstreamer-rtsp-0.10

returns

-pthread -lgstrtsp-0.10 -lgstreamer-0.10 -lgstsdp-0.10 -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lxml2 -lglib-2.0

But

ls /usr/lib/libgstrtsp*

returns

/usr/lib/libgstrtspserver-0.10.so
/usr/lib/libgstrtspserver-0.10.so.0.0.0
/usr/lib/libgstrtspserver-0.10.so.0

So, replacing the flag -lgstrtsp-0.10 by -lgstrtspserver-0.10 solved this issue for me.

add gstreamer-rtsp-server-1.0 to pkg-config.

It appears that you have not linked to the lib. "Undefined reference" usually means that you have included the necessary header files but that the linker has not found the definitions.

Try adding:

`pkg-config gstreamer-rtsp-0.10 --libs`

to your linker invocation.
