Type conflicts in in.h header files.

[Scott Porter]

Hi,

   This is my first posting here, I'm not subscribed so I'd appreciate 
any responses via email (although I will scan the lkml via Google).

   There appears to be a conflict between the structures defined in the 
following files:
       /usr/include/linux/in.h
       /usr/include/netinet/in.h

   The kernel source I am using:
      2.4.20-gentoo-r5 (I assume the Gentoo patches wouldn't cause this 
though?)

   I'm not much of a C programmer, but I'm attempting to build an old 
daemon called "mrouted" to allow me to set up a multicast router using 
linux (there doesn't seem to be ANY current documentation about this, so 
I'm assuming I still need to use this daemon?!). The kernel was compiled 
with all routing options enabled. Here's a partial error log during the 
build:

gcc -D__BSD_SOURCE  -Ibsd -O -Iinclude-linux  -DRSRR       -c -o igmp.o 
igmp.c
In file included from /usr/include/linux/mroute.h:5,
                from defs.h:34,
                from igmp.c:14:
/usr/include/linux/in.h:25: conflicting types for `IPPROTO_IP'
/usr/include/netinet/in.h:32: previous declaration of `IPPROTO_IP'
/usr/include/linux/in.h:26: conflicting types for `IPPROTO_ICMP'
/usr/include/netinet/in.h:36: previous declaration of `IPPROTO_ICMP'
/usr/include/linux/in.h:27: conflicting types for `IPPROTO_IGMP'
/usr/include/netinet/in.h:38: previous declaration of `IPPROTO_IGMP'
/usr/include/linux/in.h:28: conflicting types for `IPPROTO_IPIP'
/usr/include/netinet/in.h:40: previous declaration of `IPPROTO_IPIP'

   I did "fix" this problem by symlinking linux/in.h -> netinet/in.h, 
however, this may have caused other problems during the build, but 
that's my problem I guess!

   Cheers,
               Scott
