Hi all,
at first I should mention that this post is about Gentoo/FreeBSD for
amd64 port, using the Gentoo portage system with FreeBSD sources,
library and so on. If you're not interested in this you can stop
reading now :-).
I'm compiling "make" (usr.bin/make), but when I try to execute it I
got the following results:
[EMAIL PROTECTED] ~ # /usr/bin/make
ELF binary type "0" not known.
- -su: /usr/bin/make: cannot execute binary file
[EMAIL PROTECTED] ~ #
I must say that this *only* happends when "make" is built statically
(if you want it compiled dynamically change the Makefile). This is the
file information about it:
[EMAIL PROTECTED] ~ # file /usr/bin/make
/usr/bin/make: ELF 64-bit LSB executable, AMD x86-64, version 1
(SYSV), for FreeBSD 6.1, statically linked, for FreeBSD 6.1, stripped
[EMAIL PROTECTED] ~ #
Doing some research I found that every static binary has the same
issue, so consider the following example as trust of this:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
printf("it works!\n");
exit(EXIT_SUCCESS);
}
Compile it statically:
[EMAIL PROTECTED] ~ # gcc -static test.c -o test
[EMAIL PROTECTED] ~ # file test
test: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for
FreeBSD 6.1, statically linked, for FreeBSD 6.1, not stripped
[EMAIL PROTECTED] ~ #
Then run it:
[EMAIL PROTECTED] ~ # ./test
ELF binary type "0" not known.
- -su: ./test: cannot execute binary file
[EMAIL PROTECTED] ~ #
Now it's time to do the same as dinamically:
[EMAIL PROTECTED] ~ # gcc test.c -o test
[EMAIL PROTECTED] ~ # file test
test: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for
FreeBSD 6.1, dynamically linked (uses shared libs), for FreeBSD 6.1,
not stripped
[EMAIL PROTECTED] ~ # ./test
it works!
[EMAIL PROTECTED] ~ #
Can anyone point me a possible solution to fix this? I tried doing:
"sysctl kern.default_elf_branding=9" but it's a hack and I think it
should have a more elegant solution.
For some system information, I have the following:
binutils (version 2.17), available BFDs: elf64-x86-64 elf32-i386
elf32-i386-freebsd coff-i386 efi-app-ia32 elf64-little elf64-big

binutils (version 2.16), available emulations: elf_x86_64_fbsd
elf_i386_fbsd elf_x86_64 elf_i386
gcc: gcc (GCC) 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)
system: athlon64 3500+
freebsd sources used: 6.1-RELEASE
Thanks for any input in advance,
