I, however, really couldn't figure out this 0x08048000 location in the realelf output of your example???
Mine on a Linux machine, an executable gave me main's location as follows:
000000000040069a 82 FUNC GLOBAL DEFAULT 12 main
However, this is a 64 bit address; so do we assume that main, in any elf binary over 64-bit x86 architecture, would have an start address as 000000000040069a; where as in a 32-bi the same was at 0x08048000.
Shoul'd the same been 0x0000000008048000 over a 64-bit system????

sdl-config
sdl-config(1) General Commands Manual sdl-config(1)
NAME
sdl-config - script to get information about the installed version of SDL
SYNOPSIS
sdl-config [ --prefix[=DIR] ] [ --exec-prefix[=DIR] ] [ --version ] [ --cflags ] [ --libs ] [ --static-libs ]
DESCRIPTION
sdl-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link pro-
grams, and libraries, and plugins that use SDL. It is also used internally by the m4 macros that are included with SDL.
OPTIONS
--cflags
Print the compiler flags that are necessary to compile a program or library that uses SDL.
--exec-prefix=DIR
If specified, use DIR instead of the installation exec prefix that SDL was build with when computing the output for the --exec-pre-
fix option. This option must be specified before any of the --cflags, and --libs options.
--libs Print the linker flags that are necessary to link a program that uses SDL.
--prefix=DIR
If specified, use DIR instead of the installation prefix that SDL was built with when computing the output for the --prefix, and
--exec-prefix options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be speci-
fied before any of the --cflags, and --libs options.
--static-libs
Print the linker flags that are necessary to statically link a program that uses SDL.
--version
Prints the currently installed version of SDL on standard output.
EXAMPLES
gcc -o main.o $(sdl-config --cflags) main.c
is how you might use sdl-config to compile a C source file for an executable program.
gcc -o my_app $(sdl-config --libs) main.o util.o
is how you might use sdl-config to link compiled objects into an executable program.
