JamesJRHHello.15:47
JamesJRHCan I write Maemo programs in Haskell?15:47
L29Ahyeah if you succeed at compiling ghc15:48
JamesJRHOkay, so basically if I compile GHC for ARM, I'm good?15:48
bencohroughly (apart from the potentially missing sw deps)15:49
WizzupJamesJRH: maemo is just debian linux with some added bits15:49
L29Ahfor a particular arm for a particular glibc for a particular float abi15:49
JamesJRHOkay.15:49
Wizzupthe n900 does neon doesn't it15:49
L29Ah~scratchbox15:49
bencohit does15:49
infobotit has been said that scratchbox is a cross-compiling system that uses binfmt_misc, rpc calls, and an nfs mount to make a cross-build appear to be 100% native, and is found at http://www.scratchbox.org/, hosted by maemo now. Also at http://maemo.merlin1991.at/files/SB15:49
L29Ahit does15:49
Wizzupthen just target armhf neon15:49
Wizzupnot too hard15:49
L29AhJamesJRH: ↑15:49
bencohWizzup: no hf15:50
Wizzupwhat15:50
bencohmaemo is softfp15:50
Wizzupwell, you can run armhf binaries on the maemo kernel in a chroot at least, afaik, but ACK @ softfp15:50
Wizzuptmyk15:50
JamesJRHL29Ah: Cool!!!15:51
JamesJRHL29Ah: That could help me in trying to port NixOS to ARM maybe (for the BeagleBone Black, initially).15:52
L29Ahreport your results, i wondered about ghc on maemo as well15:52
L29Ahport nixos to openrc plz :]15:52
JamesJRHWhat's that?15:53
bencohchecking for ghc... no15:53
bencohconfigure: error: GHC is required.15:53
bencohtrying to build ... ghc.15:53
bencohI dont like the sound of it15:53
bencohand it's not even funny15:54
L29Ahyeah you need ghc to build ghc15:54
L29Ahbecause it is written in ghc15:54
bencohyeah, but ... not including a way to build a minimal ghc to bootstrap it is silly15:54
JamesJRHL29Ah: Okay, that's not something I'd be able to do. I'm a novice. You could ask on the nix-dev mailing list if you want OpenRC support.15:54
L29Ahyou can cross-bootstrap it15:54
bencohL29Ah: sure, but meh15:55
JamesJRHI know practically nothing about init systems.15:55
bencohwont work with scratchbox15:55
L29Ahwhy not?15:56
bencohwont work with autobuilder*15:56

JamesJRH12:49:18 < Wizzup> JamesJRH: maemo is just debian linux with some added bits  ← Sure, but what I'm not so sure about it how to move beyond console applications written in Haskell. What APIs is a ‘Maemo application’ allowed to assume, and how to I interface those from Haskell?16:13
L29Ahanything that works on your device is allowed16:14
L29Ahmaemo is dead so you shoudn't matter about such stuff ;)16:14
L29Ahs/matter/worry/16:14
infobotL29Ah meant: maemo is dead so you shoudn't worry about such stuff ;)16:14
JamesJRHThat's cool what infobot just did, though if it's going to take up an extra line, why not correct the full line in the first place?16:17
L29Ahin my brain or how?16:17
*** Haudegen has quit IRC16:18
bencohJamesJRH: cant do that with irc :)16:18
*** jonwil has quit IRC16:20
JamesJRHL29Ah: Like rather than me saying ‘s/APIs is/APIs are/’, only for infobot to then go and repeat the whole lot again, I could save a line by just doing it myself straight-off: … What APIs are a ‘Maemo application’ allowed to assume, and how to I interface those from Haskell?16:21
bencohJamesJRH: maemo's main GUI framework is hildon, which is heavily based on gtk16:21
JamesJRHOkay!16:21
bencohqt4 is also available on the platform16:21
JamesJRHI see. Is Hildon preferred?16:21
bencoh(actually hildon is roughly gtk with some specific stuff)16:21
bencohhildon is "native", and has a smaller memory footprint16:22
JamesJRHI remember now that at some point in the past there was a switch from Qt to Gtk.16:22
JamesJRHOkay.16:22
bencohbut a lot of apps use qt, so you can go for it as well16:22
JamesJRHI like Gtk.16:22
bencohqt is the main framework for meego/harmattan16:23
JamesJRHThough even then, I haven't yet made a GUI application in Haskell in Gtk or anything, so I should probably start with a desktop Gtk application and then see if it'll work for Hildon, or what I need to do to make it work.16:24
L29Ahah so you actually wanted to say "stfu"16:25
JamesJRHWhat?16:25
JamesJRHOh. To what?16:26
JamesJRHTo who, sorry?16:26
JamesJRHTo infobot?16:26
JamesJRHI guess so.16:27
JamesJRHBut I still think it was cool. :-]16:27
JamesJRHBut I was saying that, if anything, it's actually easier to up-arrow and edit my previous message than to type ‘s/old thing/new thing/’, so I might as well do it myself, if the substitution is preferred, because, say, not everyone understand sed notation.16:31
JamesJRHunderstands*16:31
JamesJRHI only do the sed notation to avoid clutter; personally I'd rather edit the line. But then I guess this is just something I don't like about IRC.16:32
JamesJRHBut there are many things I do like about IRC, otherwise I wouldn't have been using it for years. :-)16:33
L29Ahs/././g16:35
L29Ahah so you actually wanted to say "stfu"16:35
L29Ahs/././g16:35
L29Ahinfobot: come on16:35
JamesJRHWhat are you trying to do? Make it repeat everything?16:36
*** Haudegen has joined #maemo16:39
JamesJRHHuh, I've just notice that there's another mistake in that corrected line (“how to I”) that I could have corrected at the same time if I'd have seen it. I hate mistakes. >:-(16:40
L29Ahmove to agda16:41
JamesJRHnoticed* damn'[4~it!16:41
*** LauRoman|Alt has joined #maemo16:41
JamesJRHI give up. My Internet's being too slow right now and using Irssi over SSH don't deal with bad Internet very well at all.16:42
JamesJRHdoesn't*16:42
JamesJRHMy WAN latency is averaging twice as long as normal right now, but with sustained peaks of a few seconds. It's probably just because I'm awake in the day for once, whereas I'm usually nocturnal. Looking at the pings, I can practically see when someone else on the network downloads something for a few seconds. :-/16:49
JamesJRHWell, nearby in the network, that is; this side of wherever the bottleneck is.16:50
*** HtheB has quit IRC16:51
*** sq-one has joined #maemo16:55
kerioJamesJRH: might wanna try mosh16:58
JamesJRHSo, in theory, I should be able to port NixOS to ARM for the Neo900, port Hildon and Dalvik to NixOS, and rewrite my application, Hexiano, in Haskell and Hildon.16:58
JamesJRHSorry, this is following on from a conversation that started in #neo900.16:59
JamesJRHWith some but not all people here.16:59
JamesJRHHexiano is: https://f-droid.org/repository/browse/?fdid=org.gitorious.jamesjrh.isokeys16:59
JamesJRHkerio: Yes, I plan to.16:59
kerioJamesJRH: anything that brings us away from scratchbox is welcome17:00
L29Ahwhy do you hate scratchbox?17:00
JamesJRHWhat?17:00
JamesJRHI was just told about Scatchbox, and, at a glance, it looks like a good thing.17:00
JamesJRHScratchbox*17:01
kerioif would be a good thing if it was even remotely maintained17:01
kerioa huge part of what it does is replicate the running environment of the n900 on a computer17:01
keriowhich is something that we'd get "for free" with nix, right?17:01
*** mhlavink has joined #maemo17:01
L29Ahhuh?17:02

L29Ahi don't see no work17:03
keriowhereas nix *guarantees* that you'll have the same versions of everything17:03
bencohbringing everything together17:03
L29Ahlike make a tarball and move it or what?17:04
*** Haudegen has quit IRC17:07
bencohL29Ah: toolchain integration (at the very least)17:07
L29Ahhuh?17:07
L29Ahyou have a toolchain available in virtually any distro17:08
JamesJRHkerio: I don't know how much that applies to architectures though unfortunately. I've met-up with the core Nix developers at the last 2 FOSDEMs and I'm not convinced about the determinism wrt. architectures. Nevertheless, Nicolas Pierron in particular advocates not cross-compiling, but I don't understand why cross-compiling has to be any worse than native. Scatchbox may be the missing piece here.17:08
bencohit's not worse17:08
bencohI strongly believe it's "better" by the way, but meh :)17:08
JamesJRHScratchbox*17:08
bencohI dont understand this "native build" trend17:09
L29AhJamesJRH: check out http://exherbo.org/docs/multiarch.html (;17:09
JamesJRHbencoh: Me too, in terms of efficiency on another architecture. Are there other reasons for cross-compiling being better?17:09
L29Aher, wrong link17:10
L29Ahhttp://exherbo.org/docs/multiarch-pr.html17:10
bencohwell I do understand that some people are lazy and dont want to mess with the complications of a crossbuild (and a suitable crossbuild system), and that now that they're given powerful devices, they just want to build on it, but ...17:10
bencohstill, *meh*17:10
keriocompiling *on* a n900 is definetely a lot more painful than compiling on a modern pc17:10
L29Ahyeah it's a stopper for modern huge C++ apps17:11
bencohcompiling on debian/n900 is slow, but "easy". compiling on maemo/n900 is slow and painful because SDK has never been integrated properly17:11
bencohs/slow/dead slow/17:11
infobotbencoh meant: compiling on debian/n900 is dead slow, but "easy". compiling on maemo/n900 is slow and painful because SDK has never been integrated properly17:11
L29Ahhmm, glibc-2.20 calls uname and looks if it sucks17:13
L29Ahand a gentoo ebuild says the 2.6.32 requirement is due to nptl17:13
JamesJRH14:10:03 < L29Ah> http://exherbo.org/docs/multiarch-pr.html  ← Hey, yeah! Nix needs to catch-up in this area!!! Again, this could be the missing link.17:13
L29Ahi wonder if everything will break apart if i just remove it17:13
bencohremoving what ?17:15
L29Ahthe check17:15
bencohread the patches17:15
L29Ahi've read the url that was posted there, it's no good at worst or does effectively the same at best17:16
