Hello FreeBSD's gurus!
I like to configure a very small kernel.
I only need very few capabilities, I do not need network services.
I'm building this kernel just for starting a computer, mounting
a CD file system and copying an image from ide-cdrom to ide-hard drive.
I compiled my minikernel in a FreeBSD 4.1 box and everything was ok.
BUT... when I tried to compile it in a FreeBSD 4.2 box I got the
following error message:
--------------------------------------------------------
make depend
...
make
...
linking kernel
uipc_accf.o(.data+0x80): undefined reference to
`sysctl__net_inet_children'
*** Error code 1
--------------------------------------------------------
It seems to me that some network functions are required in version 4.2
but I do not know why.
Could you please help me?
I'm attaching a copy of my minikernel configuration.
Thanks in advance.
