Hi all, I have successfully build pjproject-2.3 source code with video support. And I am able to compile a simple program with pjsip. But when I am trying to compile a pjsip-apps sample program vid_streamutil.c, I am getting following error. /usr/local/lib/libpjmedia-i686-pc-linux-gnu.a(endpoint.o): In function `pjmedia_endpt_create': endpoint.c:(.text+0x344): undefined reference to `pjmedia_aud_subsys_init' endpoint.c:(.text+0x3a7): undefined reference to `pjmedia_aud_subsys_shutdown' /usr/local/lib/libpjmedia-i686-pc-linux-gnu.a(endpoint.o): In function `pjmedia_endpt_destroy': endpoint.c:(.text+0x79f): undefined reference to `pjmedia_aud_subsys_shutdown' collect2: error: ld returned 1 exit status I am using following command to compile gcc vid_streamutil.c -o vid_streamutil `pkg-config --libs --cflags libpjproject` Any help would be highly appreciated..
