Line number information must be enabled when compiling, e.g. by means of GCC's option "-g". Without it, you will just get offsets into the object code instead, like the 0xa720 above; besides, "text" is an ancient *nix term for a memory segment containing program code, in contrast to data segments. Typically, the "-g" option will be spefified when setting the CMAKE_BUILD_TYPE to "Debug" or "RelWithDebInfo", but see the various CMAKE_<LANG>_FLAGS, too.
