Write a simple helloworld program, as follows:
# include & lt; Stdio. H>
Int main (void)
{
Printf (" Hello, World! \n");
return 0;
}
Directly using GCC static link is normal, the generated main_static can run normally, as follows:
$GCC - static - fno - builtin main. C - o main_static
$file main_static
Main_static: ELF 32 - bit LSB executable that Intel 80386, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.18, not stripped
Change another step, Mr. O file, then calls the ld to link, link failure, however, is as follows:
$GCC - static - fno - builtin - the main c. C
$ld -static - o main main. O - L/usr/lib - lc - L/usr/lib/GCC/i686 - redhat Linux/4.4.7 LGCC - lgcc_eh

Excuse me, ladies and gentlemen, what reason is this?
