Hi I am using pjproject-1.12 source. Compiled source code in Carbide using FP2 SDK. I was able to install .sisx file in symbian phone (E-72). The phone is able to register with proxy server. However the calls are not going. I wanted to debug why the calls are not going. I am bit new to symbian platform. Can somebody provide ways how do we debug in symbian phones. When some scenario is not working , what is the best way to find out root cause. In windows or linux, we can do debugging and find the root cause, in symbian how to do that? I wanted to generate log file, so that I can know whats going on. I located a file symbian_ua.cpp in symbian_ua_gui.mmp project. In that file, there is a function *int* symbian_ua_init(). I saw a piece of code as below. pjsua_logging_config_default(&log_cfg); log_cfg.console_level = LOG_LEVEL; log_cfg.cb = &log_writer; log_cfg.decor = 0; status = pjsua_init(&cfg, &log_cfg, &med_cfg); While I was searching in google, how I can generate log file, somewhere I found, I need to set the log level and file name. So I modified above code to pjsua_logging_config_default(&log_cfg); * log_cfg.log_filename = pj_str("pjsiplog.txt"); log_cfg.level = LOG_LEVEL; * log_cfg.console_level = LOG_LEVEL; log_cfg.cb = &log_writer; log_cfg.decor = 0; status = pjsua_init(&cfg, &log_cfg, &med_cfg); After that I did a clean build, installed sisx file in my mobile and executed registration, calls, and when I tried to locate *pjsiplog.txt*file , I could not locate it in my target device (E-72). Looks the log file is never generated. Can somebody help me how I can generate log file for PJSIP in symbian.
