sorry if this seems like a stupid question but im a newbie to linux, i compiled FS 1.6 on rpi3, later i wanted to add the mod_gsmopen module so i enabled that in modules and recompiled but it never got compiled so then i tried compiling it standalone using the below commands but make clean and make install keep failing with message no rule to make target clean/install apt-get install gsm-utils apt-get install libgsmme-dev apt-get install usb-modeswitch-data usb-modeswitch cd /usr/local/src/freeswitch/src/mod/endpoints/mod_gsmopen/libctb-0.16/build make DEBUG=0 GPIB=0 make DEBUG=0 GPIB=0 install ldconfig cd /usr/local/src/freeswitch/src/mod/endpoints/mod_gsmopen/ make clean make install -- Regards, Bipin ------------------------------------------------------------------------
