Hello,

I just wonder what I do wrong.

I try to compile a simple hello.c with -pg and I fail with the following:

[enterprise:~] andreast% cc hello.c -O2 -pg -fno-show-column  -o hello.exe
/var/tmp//ccwucjWJ.o(.text+0xc): In function `main':
: undefined reference to `_mcount'
/usr/lib/libc_p.a(__sparc_utrap_setup.po)(.text+0x8): In function 
`__sparc_utrap_setup':

: undefined reference to `_mcount'
/usr/lib/libc_p.a(gmon.po)(.text+0x468): more undefined references to 
`_mcount' follow

[enterprise:~] andreast% cat hello.c
#include <stdio.h>
int main (void)
{
         printf("hello\n");
         return 1;
}

[enterprise:~] andreast% cc -v
Using built-in specs.
Configured with: FreeBSD/sparc64 system compiler
Thread model: posix
gcc version 3.4.4 [FreeBSD] 20050518

The machine I use for is a enterprise 2,
[enterprise:~] andreast% uname -ra
FreeBSD enterprise.andreas.nets 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Thu 
Feb  2 07:18:49 CET 2006 
andreast@enterprise.andreas.nets:/usr/obj/home/andreast/devel/src/sys/GENERIC 
  sparc64

Is there something known about this? Do I do something wrong when I 
buildworld? The only known thing to me is the modification of CFLAGS= -O 
-pipe.

Thanks in advance.

Andreas
