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 compiled by hand GCC, 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 ~ #
I asked before in gcc-help mailing list but they point to ask here
too. I also provide two links [1] and [2] with previous discussion
about this.

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