Hi!

I'm new here, I'm Fergus and
I'd like to learn the most from you all.

As first question, I'd like to ask you to
explain me better what does happen during
the compiling and linking time.

I looked for the answer to this question
around the web but i didn't succed in it... =(

I'm italian so please be patient with me... =)
Talk to me as easy as possible. ^^;;

Please help me.

Tnx 2 all.

Compiling means to change from C++ codes to assembly / machine code.

Hi, tnx for the answer!

I'll try to explain better the question anyway.
Maybe i should say that at this moment i use
Dev-C++.

What does the compiler do during the compiling
and linking time?

If during the compiling time the compiler change
from C++ codes to assembly / machine code, what
does happen during the linking time?

Why does the compiler need to start the linking
process although there is just one *.cpp file in
the project?

Tnx very much!

are those questions for school or something like that?

Let's see....

The compiler is a very interesting piece of software. When you compile something, you are changing the human readable information into a computer instruction list. This is in a .o file, usually called an object file.

During the linking time, all the object files are changed into .exe files, which are basically a group of object files, made into an executable file.

Even if there is just one object file, the linker is run so that the .o file is changed into a .exe file. Only on Linux are .o files executables also.

I hope this helped you. I like to see programmers that want to know how everything works, and not just rely on the ease of use of something like MS VC++.

Tnx, gnu-ehacks for the very interesting
answer, it helped me much.

The compiler is [...] an object file.

I'd wish to ask you an other question anyway.
Scuse me if I impose on you but I'm having
some difficult to find the aswer on the web
and in FAQs. =(

How the compiler behave when he face
the introduction of and #include procedure
within the code?
I mean, ASAIN the compiler include the
portion of text it was told by the procedure
in the place of the line that start with
the #include. But how this affect the compiling
and linking time?

Do the *.h files have something to do with
the compiling time or the linking one?

I hope this [...] like MS VC++.

I used to write a bit in visual basic with MS VB
but, as you can imagine, IMHO it does everything
but let you know how everything works. I hate
this. =)

I was afraid MS VC++ was something of the
same "specie" so i find interesting to try
something different.



I didn't reply you immediately because
here in italy it was a little bit late
so i went sleeping ^^;;



Scuse me for my bad english. =)
Tnx a lot!



PS for oskilian

are those questions for school or something like that?

I study Information Engeenering at the
university and during the lesson my
Informatic Elements I (1) teacher discuss
this matter and i found it very interesting
so i would like to go into it deeply.

Why did you ask me that question? =)
