[wls]

Hello guys. Need some info about gdb debugging ? I gdb a daemon magma and I get this message ?
***********************************************************************************************************************
This GDB was configured as "i386-redhat-linux-gnu"...(no debugging symbols found)...Using host libthread_db library "/lib/libthread_db.so.1".

(gdb) run

How do I solve this problem ? I am new to linux gdb debugging ?

no debug symbol means you cannot trace the program by function name. because the vendor does not add -g (presever symbol) in gcc compiling. you must trace the program by exprience and then find the function of license check. good luck
