Hi, Further to my previous email, there is another problem for which I need help. While trying to add MySQL support, I could not find the file src/sip_router/Makefile (as asked in the Getting started document (http://siprouter.onsip.org/doc/gettingstarted/ch11s05.html). The Makefile for the SER in the base directory (/lhome/.../ser/Makefile) does not refer to MySQL in the exclude_modules line (Note the ? after exclude_modules). Here is the excerpt from the Makefile: # if not set on the cmd. line or the env, exclude this modules: exclude_modules?= cpl ext extcmd \ postgres snmp \ im \ jabber mysql \ cpl-c \ auth_radius group_radius uri_radius avp_radius \ pa Does that mean that MySQL is already installed? How can I check if MySQL is already installed on my machine? I also found the following code in the Makefile but I am not sure what it means. .PHONY: dbinstall dbinstall: -@echo "Initializing ser database" scripts/ser_mysql.sh create -@echo "Done" . . . I'd be very grateful if anyone could help. Frq
