It worked ! indeed I have a glib 2.6 in /usr/local/lib and glib 2.10 /usr/lib and it was using the bad one. So when I set PKG_CONFIG_PATH to /usr/lib/pkgconfig/ everything is ok. But I don't understand why pkg_config is, by default, searching /usr/local/lib/ for glib and /usr/lib/ for all the rest (here gstreamer) Thanks a lot.

If not, then find out where is glib-2.10 installed (what prefix ?) and set the PKG_CONFIG_PATH to <prefix>/lib/pkgconfg:/usr/lib/pkgconfig. Again if you run the same command $ pkg-config --modversion glib-2.0, you should see the correct version of glib, and then your program should compile fine. Regards, Archana.
