[Haifux] Huge file with static linking

[Eli Billauer]

Hello all.

For my own peculiar reasons, I need to compile something statically.

This might appear to be a trivial question, but after quite a few trials 
it seems like I can't find the right words to ask google with. So I ask you.

Here is my program. I hope you can inderstand what it does, despite lack 
of comments... ;)

#include stdio.h
int main() {
 puts(Hello, world\n);
}
And here's my little session:

[EMAIL PROTECTED] helloworld]$ gcc -static -o hello hello.c
[EMAIL PROTECTED] helloworld]$ ls -l hello
-rwxrwxr-x1 eli  eli441940 Mar  6 21:05 hello*
[EMAIL PROTECTED] helloworld]$
As you can see, this little program takes 440 kB. Hmmm. Why does this 
look too much to me?

I mean, even without glibc and other wonders, surely one could implement 
puts with less?

Any suggestions of how to shrink this down to some normal size?

Thanks in advance,
Eli

You forgot -O2, and you forgot to give your machine a name! 

 [EMAIL PROTECTED] helloworld]$ ls -l hello
 -rwxrwxr-x1 eli  eli441940 Mar  6 21:05 hello*
 [EMAIL PROTECTED] helloworld]$

You forgot to run strip(1).

strip(1). Anything beyond that requires assembly and careful
massaging.

 Thanks in advance,

We aim to please.

Actually, neither. I figured out that -O2 didn't help. As for my
machine's name, it's like getting a dog who already responds to a name.
You don't change it. ;)

Hmmm. I forgot to mention that I already tried that.

[EMAIL PROTECTED] helloworld]$ gcc -O2 -static -o hello hello.c
[EMAIL PROTECTED] helloworld]$ ls -l hello
-rwxrwxr-x??? 1 eli? eli??? 441940 Mar? 6 21:27 hello*
[EMAIL PROTECTED] helloworld]$ strip -s hello
[EMAIL PROTECTED] helloworld]$ ls -l hello
-rwxrwxr-x??? 1 eli? eli??? 373248 Mar? 6 21:27 hello*

Really? This is the end of it? How come /sbin/insmod.static is so
small? What do "they" know that I don't?

? ? Eli

Do you know for a fact that insmod.statis was compiled with -static? 

I was under the impression that strip does a good job even when using
-static. Apparently, it doesn't. I'll think about it, and if anyone
knows how to get the binary's size down after strip is done with it,
do tell.
