Hi all, please, help me. I download newest PJSIP, released on 2012-07-03. I compiled it ./configure make dep && make, installed it sudo make install on ubuntu 12.04. Everything seems to be OK, no error message. Than I try my own program, for first start I just copy pjproject-2.0.1/pjsip-apps/src/samples/simple_pjsua.c to my voip.c. I add all libs to linker, I didn't find pjsip-core and pjlib as is on this page http://www.pjsip.org/docs/latest/pjsip/docs/html/group__PJSUA__LIB.htm, I try add pjsip-x86_64-unknown-linux-gnu and pj-x86_64-unknown-linux-gnu. Here is linker command: gcc -o "uh13" ./voip.o -lg7221codec-x86_64-unknown-linux-gnu -lgsmcodec-x86_64-unknown-linux-gnu -lilbccodec-x86_64-unknown-linux-gnu -lmilenage-x86_64-unknown-linux-gnu -lpj-x86_64-unknown-linux-gnu -lpjlib-util-x86_64-unknown-linux-gnu -lpjmedia-audiodev-x86_64-unknown-linux-gnu -lpjmedia-codec-x86_64-unknown-linux-gnu -lpjmedia-x86_64-unknown-linux-gnu -lpjnath-x86_64-unknown-linux-gnu -lpjsip-simple-x86_64-unknown-linux-gnu -lpjsip-ua-x86_64-unknown-linux-gnu -lpjsip-x86_64-unknown-linux-gnu -lpjsua-x86_64-unknown-linux-gnu -lportaudio-x86_64-unknown-linux-gnu -lresample-x86_64-unknown-linux-gnu -lspeex-x86_64-unknown-linux-gnu -lsrtp-x86_64-unknown-linux-gnu but still get a lot of (just few last lines): pjsua_aud.c:(.text+0x1830): undefined reference to `pjmedia_conf_get_signal_level' /usr/local/lib/libpjsua-x86_64-unknown-linux-gnu.a(pjsua_aud.o): In function `pjsua_player_set_pos': pjsua_aud.c:(.text+0x1fd5): undefined reference to `pjmedia_wav_player_port_set_pos' /usr/local/lib/libpjsua-x86_64-unknown-linux-gnu.a(pjsua_aud.o): In function `pjsua_set_no_snd_dev': pjsua_aud.c:(.text+0x3328): undefined reference to `pjmedia_conf_get_master_port' collect2: ld returned 1 exit status What did I wrong?
