Bug 18073 – linux-2.4.20-gentoo-r2 fails to compile with ip_conntrack_ftp

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description PJ 2003-03-23 23:51:24 UTC]

First off, I do not believe this bug is a dupe of bug #14195, as his error msg 
is different, and is occuring in -r1. My kernel compiles fine in -r1, but fails 
in -r2.

When I go to compile this new revision during the make bzImage stage, the 
following occurs:
 
make[3]: Circular /usr/src/linux-2.4.20-gentoo-r2/include/linux/netfilter_ipv4/i
p_conntrack_helper.h <- /usr/src/linux-2.4.20-gentoo-r2/include/linux/netfilter_
ipv4/ip_conntrack.h dependency dropped.

I am of course am using ip_conntrack_ftp (NetFilter FTP tracking) compiled into 
the kernel.
 
At first I thought this was because I changed the default FTP port in 
include/linux/netfilter_ipv4/ip_conntrack_ftp.h, but it fails even with the 
default FTP port of 21. I deleted the linux-2.4.20-gentoo-r2 directory and re 
emerged it just to be sure, and the error still occurs.

I have attached my .config file (as config with no . because windows is a pain 
in the .ass.)

The system is a P3 600, gcc version 3.2.2, Gentoo 1.4 RC3, with the following 
make.conf settings: 
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=pentium3 -O3 -pipe"

Thanks. =)

ok, this should be fixed with a small patch. let me test things a bit to ensure that this patch 
won't b0rk something else, then i'll upload it. 
 
thanks,
