Hi Guys: Starting a new thread.... While updating app_rpt on my hub server; while I thought everything updated, I just tried again and see that there were errors: chan_pi.c: In function ‘GPIODirection’: chan_pi.c:480: warning: implicit declaration of function ‘i2c_smbus_read_byte_data’ chan_pi.c:490: warning: implicit declaration of function ‘i2c_smbus_write_byte_data’ chan_pi.c: In function ‘load_module’: chan_pi.c:3086: error: ‘I2C_SLAVE’ undeclared (first use in this function) chan_pi.c:3086: error: (Each undeclared identifier is reported only once chan_pi.c:3086: error: for each function it appears in.) make[2]: *** [chan_pi.o] Error 1 make[2]: Leaving directory `/usr/src/astsrc/asterisk/channels' make[1]: *** [channels] Error 2 make[1]: Leaving directory `/usr/src/astsrc/asterisk' make: [upgrade-acid] Error 2 (ignored) mkdir -p /var/lib/asterisk/sounds/rpt cp -a sounds/* /var/lib/asterisk/sounds I followed the following instructions on the allstarlink website: For the ACID distribution (and other Linux platforms): cd /usr/src rm -rf astsrc wget http://x.allstarlink.org/svn-trunk.tar.gz -O- | tar xzv mv trunk astsrc cd astsrc make upgrade-acid This server is in a Hospital DC and also running other stuff, a D-STAR reflector and ircddb server s/w, so updating it to Debian, etc., is not an option. Help! Thanks, Ramesh.
