Comment 1 Peter Korsgaard 2009-04-27 07:41:46 UTC 
Sorry, I cannot reproduce it here. It builds fine for x86-64 with ipv6 support her (Debian x86-64). Please post your .config and info about your host setup if you still have this problem.

Comment 3 Floris Bos 2009-04-27 12:45:08 UTC 
Problem only seems to occur when cross compiling on a 32-bit host for a 64-bit target.

Does work in the x86_64 edition of Archlinux
Comment 4 Peter Korsgaard 2009-04-27 14:10:19 UTC 
hmm, I'm afraid my machines all run 64bit, so you'll have to debug that yourself. try comparing libext4.a from the 32bit and 64bit builds.
Comment 5 Thomas Petazzoni 2009-08-07 20:19:27 UTC 
I have a 32 bits Ubuntu, I took your .config and compiled it with the latest Buildroot Git. And it worked nicely. iptables was generated, including IPv6 support. I haven't tested the resulting binaries, though, but at least, the build completed.

So I'm marking this bug as WORKSFORME. If you are still having the issue, don't hesitate to re-open it. Thanks for your contribution!
