c - How to map .so files to source files in gdb -

i have core dump file. when seek open in gdb. able see backtrace (with address , corresponding functions) corresponding function in mapped .so files not source.

bt looks this

#0 0xf611b39c in xxfun () /lib/libxx.so.0 $file /lib/libtxx.so.0 /lib/libtxx.so.0: elf 32-bit lsb shared object, intel 80386, version 1 (sysv), not stripped

able display symbols using nm!

queries:- 1) how can map .so files source files 2) not able display info locals/args. how can these data?

when seek display

#info locals no symbol table info available. #info args no symbol table info available.

please allow me know if need more info.

exactly "n.m." commented, need libxx.so built debug info (usualy -g switch @ compile time).

that provide both address source mapping, , info locals, args, etc.

c debugging gdb
