Hi, http://www.pjsip.org/testing/0.5.6.5/footprint-i386-linux.htm I am looking at the above url and this is what I did. 1)I modified the build.mak.in file in the root directory. 2) then I copied user.mak.sample to user.mak and made it the same as on this page 3) then I coped the config_site_sample.h sample file to site.config.h and added the define statements on the top. tried ./configure and it worked but when I do make I get the error : make[3]: Leaving directory `/home/s/pjproject-1.1/third_party/build/portaudio' make[2]: Leaving directory `/home/s/pjproject-1.1/third_party/build/portaudio' make[1]: Leaving directory `/home/s/pjproject-1.1/third_party/build' make[1]: Entering directory `/home/s/pjproject-1.1/pjmedia/build' make -f /home/s/pjproject-1.1/build/rules.mak APP=PJMEDIA app=pjmedia depend make[2]: Entering directory `/home/s/pjproject-1.1/pjmedia/build' .pjmedia-i386-linux-gcc.depend:1: *** missing separator.
