Hi all,
I'm porting FreeBSD to Gentoo for the Summer of Code project
"Gentoo/FreeBSD for Amd64", and I need a little help about gcc binary
output when compiling files. I was pointed here from gcc-help mailing
list.
I compiled by hand GCC and binutils (2.17), and when I compile some
file the output format is "UNIX - System V". I got this with
`readelf -h program`.
The problem is that I need the default binary output must be "UNIX -
FreeBSD" and for now I can't fix it without help.
BTW, If the output is "UNIX - System V" I can't run static compiled
files, it shall be fixed changing the output behaviour. For example
with the following small C program:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
printf("it works!\n");
exit(EXIT_SUCCESS);
}
root@localhost ~ # gcc -static test.c -o test
root@localhost ~ # readelf -h test | grep "OS/ABI"
OS/ABI: UNIX - System V
root@localhost ~ # ./test
ELF binary type "0" not known.
- - -su: ./test: cannot execute binary file
root@localhost ~ #
If any information is required tell me (such gcc config line, binutils
config line, emulations or BFDs compiled).
As I posted here in other list before pointed to this one, I included
the links for reference:

Any input in this topic will be very apreciated.
Thanks for all in advance,
