Similarly, a variable cppflags exists with switches to be passed to the c or c++ preprocessor Another closely related topic is name mangling, which determines how symbol names in the code are mapped to symbol names used by the linker Similarly, fflags enables the addition of switches for a fortran compiler

The absence of symbol and debugging information complicates the program analysis of the binary
The effect of strip can also be achieved via a compiler or linker to perform the same process
The.debug_info section of an elf contains information generated by compilers to describe the source code while debugging by keeping symbols and its type, scope, file, line number, etc. A weak symbol denotes a specially annotated symbol during linking of executable and linkable format (elf) object files By default, without any annotation, a symbol in an object file is strong. In linux, the system.map file is a symbol table used by the kernel
A symbol name may be the name of a variable or the name of a function The system.map is required when the address of a symbol name, or the symbol name of an address, is needed It is especially useful for debugging kernel panics and kernel oopses.
