Re: solved -- if_indextoname missing in libc.so [linux]

[Ingo Krabbe <i dot krabbe at dokom dot net>]

It seems that I've forgotten to mention, that this error occurred on
linux.

Meanwhile I solved the problem and it would be nice if someone could
check in the change into CVS:

The problem are missing functions in libc.so called:
	if_indextoname, __GI_if_nametoindex and __GI_if_indextoname

The bug is that the function definitions live in
sysdeps/unix/sysv/linux/if_index.c and are stated to be

	libc_hidden_def (if_nametoindex) and
	libc_hidden_def (if_indextoname),

while the prototypes live in sysdeps/gnu/net/if.h without
libc_hidden_proto !

I copied the sysdeps/gnu/net/if.h into sysdeps/unix/sysv/linux/net/if.h
and addded the two lines

	libc_hidden_proto (if_nametoindex) and
	libc_hidden_proto (if_indextoname)

(around line 192ff.).

This works (:for:) now ...

BYE INGO
