[SOLVED] GStreamer 1.19 error: gst/sdp/sdp.h: No such file or directory

Aquarius_Girl · 01-29-2021, 08:14 AM

Ubuntu 18.04

Code:

$ gst-inspect-1.0 --gst-version
GStreamer Core Library version 1.19.0.1

My helloworld program has these includes:

Code:

#include <gst/gst.h>
#include <glib.h>
#include <gst/sdp/sdp.h>

Compiling it as follows:

Code:

$ gcc -Wall helloworld.c -o helloworld $(pkg-config --cflags --libs gstreamer-1.0)
helloworld.c:3:10: fatal error: gst/sdp/sdp.h: No such file or directory
 #include <gst/sdp/sdp.h>
          ^~~~~~~~~~~~~~~
compilation terminated.

I followed this: https://www.collabora.com/news-and-b...mer-gst-build/

Code:

$ locate gst/sdp

What information should I present here for you to help me?

As you can see from above, it's either <gstreamer-1.0/gst/sdp/sdp.h> or pkg-config --cflags gstreamer-1.0 plus <gst/sdp/sdp.h>, i.e. place $(pkg-config --cflags) before, and $(pkg-config --libs) after the source on the command line:

Code:

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

Alternatively, you can do it like this:

Code:

CFLAGS="$(pkg-config --cflags gstreamer-1.0)"
LDFLAGS="$(pkg-config --libs gstreamer-1.0)"
gcc -Wall $CFLAGS helloworld.c $LDFLAGS -o helloworld

GCC reads its options from left to right. If it encounters helloworld.c first, it processes the file, sees <gst/sdp/sdp.h> in it, but cannot find /usr/include/gst/sdp/sdp.h, even although pkg-config sets -I/usr/include/gstreamer-1.0 afterwards.
