hi,
this is my first post.i want to know as to how do i see the source code for programs compiled in gcc .there is a command but i am not getting it .could anyone help me out.
bye

i think that you maybe find the "Building and Installing Software Packages for
Linux" article can answer your question.

hi
sorry to confuse u guys. i meant how do i see the assembly code of the program written and not the "source code".

You'd need a disassembler. Once code has been compiled it's no longer 'human-readable' because it's in binary (or can be viewed as hex). A disassembler or decompiler would give you some idea of the source code, but it wouldn't be as the programmer wrote it, it would be a 'best guess' of the disassembler. If you want source code, most linux programs provide it.

hi,
where do i get the disassembler from,could u send me the link for the d/w.

Search for dasm2. I'm not sure what you're hoping to gain from this...it's only going to give you a whole load of assembly language that'll be incredibly difficult to understand.

hi,

my aim is just to optimize the code when there are memory constraints,and by looking at assembly i hope to get an idea of writing efficent programs.
thx

Well you're not going to learn that from disassembled code. You're better of reading a book about optimising assembly language or joining some forums/newsgroups. Disassembled code isn't going to be optimised or efficient, even if it was originally written that way because when the code was compiled certain things may have happened to it (like loops being unrolled) that are not how the programmer originally wrote it. In short even a program written in assembly language will look different once it's been compiled and disassembled.

hi
thx for the info,i will keep that in mind.
