• Status: RESOLVED FIXED
• Product: Gentoo Linux

Build of iptables-1.4.0-r1 fails here with the following error:

cc -O2 -Wall -Wunused -I"/lib/modules/2.6.26-openvz.git-35f41f1/build"/include -I"/lib/modules/2.6.26-openvz.git-35f41f1/source"/include -Iinclude/ -DIPTABLES_VERSION=\"1.4.0\"  -fPIC -o extensions/libxt_sctp_sh.o -c extensions/libxt_sctp.c

I'm not sure why I failed to reproduce this bug with gcc-4.1.2 but it's perfectly reproducible with gcc-4.3.2.

Created attachment 171422 [details, diff]
iptables-1.4.0-2.6.26-kernel.patch

Since kernel 2.6.26 is in process of stabilization now I think it's worth to apply this trivial patch, which fixes this issue.

Fails for me too, with GCC 4.1.2.

[Comment 3 Albert Zeyer 2008-12-05 19:14:51 UTC]

My kernel: vanilla-sources-2.6.26.7 (which is stable)

[Comment 4 Albert Zeyer 2008-12-05 19:15:14 UTC]

The provided patch solves the problem, thanks.

[Comment 5 Peter Volkov (RETIRED) 2008-12-06 14:43:34 UTC]

Ok, I've commited patch. In any case it does no harm at all. FIXED.
