Hide function name in GCC compilation

Question

I am compiling a c "hello world" program that juste include one simple function and a main function.

I am using GCC under Linux.

When I run readelf command on the binary, I can see symbol table and I can see function names in clear.

• Is there a way to tell GCC (or the linker) to not generate this symbol table?

• Is it possible to tell GCC to store only functions addresses, without storing function names in clear?

Answer 1

Use the -s option to strip the symbol table:

gcc -s -o hello hello.c
