[OpenSIPS-Users] how to use gdb for opensips

[fun_yang at foxmail.com]

i use "gdb attach  28188" and then  "b acc_logic.c:1302". (function w_do_acc_3)and i want to know how the acc module works.
and the log will show as follows,but the break won't work.i don't know why


These logs are printed in the acc_log_request function,so i "b acc.c:313",it also doesn't work,this confused me
log as follows:
