I am trying to build PJSIP 0.7.0, "out of the box" without any changes, and the build is failing. As per the build instructions, I run the following commands: ./configure make dep make clean make The final command (make) fails. The following are the last few lines of the output: gcc -o ../bin/samples/confsample-i686-pc-linux-gnu \ output/samples-i686-pc-linux-gnu/confsample.o \ -L/home/moshem/Projects/PjSip0/pjsip/pjlib/lib -L/home/moshem/Projects/PjSip0/pjsip/pjlib-util/lib -L/home/moshem/Projects/PjSip0/pjsip/pjnath/lib -L/home/moshem/Projects/PjSip0/pjsip/pjmedia/lib -L/home/moshem/Projects/PjSip0/pjsip/pjsip/lib -L/home/moshem/Projects/PjSip0/pjsip/third_party/lib -lpjsua-i686-pc-linux-gnu -lpjsip-ua-i686-pc-linux-gnu -lpjsip-simple-i686-pc-linux-gnu -lpjsip-i686-pc-linux-gnu -lpjmedia-codec-i686-pc-linux-gnu -lpjmedia-i686-pc-linux-gnu -lpjnath-i686-pc-linux-gnu -lpjlib-util-i686-pc-linux-gnu -lresample-i686-pc-linux-gnu -lgsmcodec-i686-pc-linux-gnu -lspeex-i686-pc-linux-gnu -lilbccodec-i686-pc-linux-gnu -lportaudio-i686-pc-linux-gnu -lpj-i686-pc-linux-gnu -lm -luuid -lnsl -lrt -lpthread -lssl -lcrypto /usr/bin/ld: cannot open output file ../bin/samples/confsample-i686-pc-linux-gnu: No such file or directory collect2: ld returned 1 exit status make[2]: *** [../bin/samples/confsample-i686-pc-linux-gnu] Error 1 rm output/samples-i686-pc-linux-gnu/confsample.o make[2]: Leaving directory `/home/moshem/Projects/PjSip0/pjsip/pjsip-apps/build' make[1]: *** [samples] Error 2 make[1]: Leaving directory `/home/moshem/Projects/PjSip0/pjsip/pjsip-apps/build' make: *** [all] Error 1 I am using Linux 2.4.21 on an x86 machine, with GCC 3.2.3.
