**** BEGIN LOGGING AT Mon Apr 28 02:59:59 2014 Apr 28 03:26:49 PaulFertser, I see, thank you Apr 28 03:27:09 then I know why gnutoo suggest me to use OE Apr 28 03:36:07 ayaka: for many usecases it's easier now to use upstream debian or gentoo Apr 28 03:37:00 PaulFertser, but for debian, you know the cross compile will have problem Apr 28 03:37:42 PaulFertser, the toolchain from emdebian can't work for a long time(although the jessie one has been able to work) Apr 28 03:38:27 but most of packages in debian will have problem in multiarch in cross install case Apr 28 03:39:18 how about gentoo Apr 28 03:40:21 actually about debian, there is another problem for me, package a software and do cross compile Apr 28 03:41:02 I know how to package a software in old policy(don't support multiarch) but cross build always causing problem Apr 28 03:41:03 ayaka: use native compilation Apr 28 03:41:16 PaulFertser, but it is too slow Apr 28 03:41:16 Will save you helluva time Apr 28 03:41:48 ayaka: get beaglebone black or one of marvell's "plugs" or some other beefy arm hardware, and it'll be fast. Apr 28 03:42:10 PaulFertser, yes it will, but I am happen with buildroot now Apr 28 03:42:59 PaulFertser, my arm target is exynos 4412, 4 cores 1.7G with 1G RAM Apr 28 03:43:00 My impression was that OpenWrt is way more advanced than buildroot. Apr 28 03:43:16 Native compilation on that should be really fast. Apr 28 03:43:28 PaulFertser, yes I feel openwrt is much better than buildroot I see Apr 28 03:43:58 sorry, yes I feel openwrt is much better than buildroot Apr 28 03:44:02 I guess both my laptop and desktop are less powerful than that board. Apr 28 03:44:35 PaulFertser, well my desktop is a i5 3.2Ghz with 8 RAM Apr 28 03:45:26 and the new laptop is i7 3.0 GHz with 8G ram Apr 28 03:45:35 much faster than exynos 4 Apr 28 03:45:45 Probably it'll be faster to use qemubuilder then, but still I highly recommend just usual upstream Debian. Apr 28 03:46:55 PaulFertser, but if the native compilation become the "normal" and common way in embedded develop, I will feel no guilt to use it Apr 28 03:47:20 PaulFertser, about "qemubuilder"? do you mean using qemu with chroot Apr 28 03:47:33 it maybe the most slow way Apr 28 03:48:02 ayaka: well, it's seminormal, just the targets become powerful enough, and too much of the software is still not fixed properly for cross-build. Apr 28 03:48:35 ayaka: qemubuilder is like Debian pbuilder running in Qemu, I think on your desktop it'd still be pretty fast. Apr 28 03:50:24 ayaka: you can also mix native and cross-building, e.g. use native (or just pre-built binaries from Debian archive) for most of the system and cross for the soft you develop yourself (assuming you care to not break cross-build ;)). Apr 28 03:51:57 OE is quite a pain because: 1. It's like Gentoo, has many packages tracking upstream pretty closely, every now and then something breaks. 2. It has to fix plenty of cross-build issues along the way. Apr 28 03:56:22 PaulFertser, yes it is really a problem, but for debian, the big problem is that the cross build doesn't ready at all, some package like libbz2 doesn't support to be installed in cross environment Apr 28 03:56:44 my recent work is doing a hardware encoder in exynos 4 Apr 28 03:57:59 it wil submit to gst using the latest git verstion Apr 28 03:58:08 ayaka: well, that's why Debian has the biggest archives of packages for the widest number of architectures: they just natively build all of them; instead of wasting time on trying to fix everything, they just spend more CPU cycles. Apr 28 03:58:37 PaulFertser, yes I know debian using native build Apr 28 03:58:59 some times, I think I need to let teacher buy one Apr 28 03:59:00 With OE you have no choice but to fix every silly breakage in every package you need. Apr 28 03:59:37 With Debian you can use all those ready pre-compiled system packages and cross-build your own. Apr 28 03:59:47 Less time fixing shit, more time developing. Apr 28 04:00:20 that is right Apr 28 04:01:13 I shall really think of the native compilation Apr 28 04:01:29 PaulFertser, thank you very much Apr 28 04:02:40 ayaka: welcome Apr 28 04:03:47 P.S I haven't decide my laptop system(I just order it yesterday), I may not decide to use debian as I always be said "too old" in the other channel Apr 28 04:05:11 is it gentoo a good choice, I was decide to use fedora, as it have well support in selinux(I am learning it) and the latest tested package Apr 28 04:05:27 how about gentoo Apr 28 04:08:12 Debian testing has always reasonably new packages Apr 28 04:08:21 unstable even newer Apr 28 04:08:34 Gentoo is often more hassle but I still like it. Apr 28 04:08:39 So I'm using both. Apr 28 04:12:32 I see Apr 28 04:12:33 thank you Apr 28 04:21:16 ayaka: BTW Debian jessie will probably have better cross-build support, including cross-compilers in the archive, some links https://wiki.debian.org/MultiarchCrossToolchainBuild https://wiki.debian.org/ReleaseGoals/CrossToolchains https://wiki.debian.org/CrossTranslatableBuildDeps https://wiki.debian.org/CoinstallableToolchains Apr 28 04:26:06 pabs3, yes, I have tried it Apr 28 04:26:13 pabs3, thank you **** ENDING LOGGING AT Tue Apr 29 02:59:58 2014
