<div dir="ltr">Hi Andrew,<br><br>Iptables is very useful, as is libnl & hostapd if you want your device to be a hotspot. This is functionality I will need in the near future, but I was okay with not installing these at the current stage. There might be a good chance the enthusiast would appreciate this kind of configurability. Is there a suitable alternative, or perhaps this belongs in CBLFS instead?<br><br>Regarding e2fsprogs & dropbear...<br>I haven't tested with the latest dropbear, I'll rebuild later this week, but the situation was thus:<br><br>I'm targeting ARM1176; the version of dropbear previously used had configuration scripts (config.guess and config.sub) dating from 2007, which don't support the architecture. I updated those scripts to the latest versions from Savannah. I haven't tested with the new dropbear.<br><br>I'm not quite sure where the issue with e2fsprogs came in; I surmised that it was due to the target arch not having an unsigned 64-bit type. It's only used in 1 small section of ext2fs/unix_io.c that is for very large filesystems - but rather than just commenting it out, I rewrote it using an unsigned 32-bit type that the ARM supported.<br><br>lib/ext2fs/unix_io.c: 933 - 940:<br><br>#ifdef BLKDISCARD<br> __uint64_t range[2];<br><br> range[0] = (__uint64_t)(block) * channel->block_size;<br> range[1] = (__uint64_t)(count) * channel->block_size;<br><br> ret = ioctl(data->dev, BLKDISCARD, &range);<br>#else<br><br>Cheers, Neil<br><br><br><div>> Date: Thu, 17 Oct 2013 15:05:31 -0400<br>> From: andrew@bradfordembedded.com<br>> To: neil.bradley@windowslive.com<br>> Subject: Re: CLFS Embedded<br>> <br><br> ...<br> <br>> <br>> > 11.5.1 - iptables had same issue with config.? - but was in build-aux directory.<br>> > --enable-libipq misspelt?<br>> > Conflicts between net/if.h & linux/if.h : <br>> > change net/if.h to linux/if.h in ipt_headers.... .h & include/xtable.h<br>> > also netinet/in.h to linux/in.h<br>> > also had u_int instead of uint<br>> > These issues in both 1.4.19.1 & 1.4.20.0<br>> <br>> Yeah, programs that include both libc and linux headers are annoying<br>> with musl as it separates itself from Linux quite well (it's one of the<br>> only libc that doesn't rely on linux headers in order to build).<br>> Busybox does something similar, thus the somewhat ugly sed lines there<br>> to remove building of ifplugd.<br>> <br>> I'd like to fix ifplugd, as it's a nice feature.<br>> <br>> Is it worth keeping iptables for a normal embedded build?
