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
The kernel source I am using:
2.4.20-gentoo-r5 (I assume the Gentoo patches wouldn't cause this
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
gcc -D__BSD_SOURCE -Ibsd -O -Iinclude-linux -DRSRR -c -o igmp.o
In file included from /usr/include/linux/mroute.h:5,

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!
