# 18:41:42 redengin can anyone give me a hint as to why Clooog/ppl blows up?
# 18:41:51 imMute what's the error?
# 18:42:18 redengin "undefined reference to std::length_erorr::length_error()"
# 18:42:31 redengin repeated many many times
# 18:42:37 imMute never seen that one, so I'm useless here. sorry
# 18:43:43 redengin any idea what Cloog depends on?
# 18:44:20 y_morin redengin: please post your .config on some pastebin, so I can get a peek at it.
# 18:44:26 imMute best bet is to hope that y_mo.... bing
# 18:44:34 imMute y_morin: read my mind :)
# 18:44:36 y_morin imMute: hello! ;-)
# 18:44:42 y_morin Hehe!
# 18:45:40 y_morin redengin: I'm off for dinner, so I'll be back on-line in ~2h30. Put that .config on-line, I'll grab it on my way back then, and I'll give it a spin.
# 18:46:02 redengin k, will do thanks
# 18:46:10 y_morin redengin: I remember that error, but I can't remember the root cause, so I'll have to respin it here to F5 my memory.
# 18:46:24 y_morin is off for a very good meal! :-)
# 18:52:02 redengin y_morin, http://pastebin.com/6AGrVTJE
# 19:06:11 sangelion joins #crosstool-ng
# 19:06:50 sangelion hello
# 19:43:20 redengin y_morin, disabling graphite removed ppl/Cloog, so crosstool-ng will build now
# 20:32:17 y_morin sangelion: hey!
# 20:32:49 y_morin redengin: OK if you do not want the optimisations that graphite can provide. I'll look at your .config now.
# 20:33:51 y_morin redengin: also, I can see that you are using a very old version. 1.9.3 is long un-maintained. The latest version is 1.16.0.
# 20:34:31 y_morin redengin: I won't try your .config, please updgrade, and if you still have the issue, we can look again at solving it.
# 20:35:39 redengin y_morin, it actually died with this: http://sourceware.org/ml/libc-help/2008-11/msg00002.html
# 20:35:49 redengin y_morin, whats an old version?
# 20:36:13 y_morin redengin: the .config you posted refer to crosstool-NG 1.9.3, when 1.16.0 is available.
# 20:51:27 sangelion can I ask something..
# 20:52:29 sangelion what is the different between ct-ng build and ct-ng build.4
# 20:53:35 redengin ah, whoops, I scrolled to the bottom of the list and didn't check closely enough... let me try with the latest :)
# 20:53:43 y_morin sangelion: 'ct-ng build.4' will force 4 parallel build jobs
# 20:54:14 sangelion so the build process will more faster than build without 4?
# 20:54:15 y_morin sangelion: while 'ct-ng build' will use the number of parallel jobs you specified in the menuconfig
# 20:54:41 y_morin sangelion: id you set the number of // jobs in menuconfig to 0 (zero), then 'ct-ng build' will use all your CPUs.
# 20:54:52 y_morin id -> if
# 20:55:41 y_morin sangelion: depends on the number os processors you have, *and* the setting in menuconfig
# 20:56:06 y_morin os -> of
# 20:56:08 y_morin curses his keyboard-dislexya...
# 20:56:38 y_morin redengin: I've recently 'fixed' the display on the downloads page to be sortable.
# 20:56:58 sangelion :D i dont explore menuconfig.. just taking the sample and change the location of toolbuild...
# 20:57:02 y_morin redengin: and the latest version available is always advertised at the top of crosstool-ng.org, and in this channel
# 20:57:21 sangelion still building right now..
# 20:58:07 sangelion configure: error: expat is missing or unusable... what does that mean
# 20:58:51 y_morin sangelion: Ah, the infamous expat issue, that we do not yet manage to solve (and I did not manage to clearly understand the context in which it happens).
# 20:59:04 y_morin sangelion: when does that happen (what step) ?
# 20:59:44 sangelion after build .. installing cross-gdb
# 21:00:06 sangelion [ERROR] make[2]: *** [configure-gdb] Error 1
# 21:00:08 sangelion [ERROR] make[1]: *** [all] Error 2
# 21:00:13 y_morin sangelion: (it is *not* after build, it *is* part of the build).
# 21:00:19 y_morin sangelion: what host distro are you using?
# 21:00:23 sangelion haha
# 21:00:40 sangelion i'm using ubuntu
# 21:00:53 y_morin sangelion: version?
# 21:03:07 sangelion 12.04...
# 21:03:34 sangelion is it a bug?
# 21:07:05 y_morin sangelion: do you have the libexpat1-dev package isntalled?
# 21:07:23 y_morin sangelion: dpkg --get-selections |grep expat
# 21:08:02 sangelion libexpat1install
# 21:08:48 y_morin sangelion: Then install the missing libexpat1-dev package
# 21:09:08 sangelion okkk..
# 21:10:21 sangelion do i need to make again?
# 21:10:28 sangelion or just build
# 21:11:38 y_morin sangelion: just re-run: ct-ng build
# 21:17:20 sangelion just curious.. what package should we install before successfully use this crosstool-ng?
# 21:19:04 y_morin sangelion: at least what ./configure checks for.
# 21:19:19 y_morin sangelion: that provides for a basic, strictly required list.
# 21:19:47 y_morin sangelion: More 'advanced' stuff may require other stuff, but .configure can not easily check for them
# 21:21:20 y_morin sangelion: for example, the devel expat stuff can not be checked by ./configure, because ./configure can only check stuff for crostool-NG's host, while we need the expat devel stuff for the toolchai's host, which can be different in case of a canadianc-ross.
# 21:21:28 sangelion maybe the documentation for some basic packages can be listed... or it is already has??
# 21:22:07 y_morin sangelion: it's not possible to list exact packages (as in 'distribution packages'), because the names may differ from distro to distro.
# 21:22:47 y_morin sangelion: ./configure checks for programs and libs it needs, it's up to the user to know his/her distro to know what package to install is configure is whining on something.
# 21:23:38 sangelion so when .configure detect no.. the user should try to install it? It doesn't give any warning or error..
# 21:24:01 sangelion that's why I think user can ignore that "no"
# 21:24:37 sangelion or it still function if there is no when .configure?
# 21:24:59 sangelion ./configure
# 21:25:13 y_morin sangelion: some of the features ./configure checks for are required, and ./configure will stop. But other stuff is optional, and ./configure warns and continues, and disables appropriate features from the menuconfig.
# 21:26:21 sangelion Oh I see.. that's why I can bypass that process :D
# 21:26:26 y_morin sangelion: yes, if configure does not bail out, then you can use crostool-NG, but some options in the menuconfig may not be available.
# 21:27:00 y_morin sangelion: for example, if you do not have 'cvs' on your machine, you will not be able to use the newlib repository, but still be able to use the newlib releases.
# 21:27:27 sangelion hmm.. i don't have cvs and svn if i not mistaken..
# 21:27:34 y_morin sangelion: and if you do not have 'svn', then you can not select 'eglibc', has eglibc is only available through svn.
# 21:28:16 sangelion I try to install that svn and cvs.. but my distro cannot locate it..
# 21:28:21 y_morin sangelion: but a mising cvs and/or svn will not abort ./configure, because then you can still use othe C libraries, so ./configure continues, but disables impossible menuconfig options.
# 21:28:23 devcoder joins #crosstool-ng
# 21:28:58 y_morin sangelion: 'cvs' is probably in package 'cvs', and 'svn' is in package 'subversion'
# 21:29:07 sangelion that cvs and svn have nothing to do with build process?
# 21:29:56 y_morin sangelion: As I said, above: cvs is only required if you want to build a toolchain based on newlib, *and* you want to use the newlib sources from the repository.
# 21:30:10 y_morin sangelion: and svn is *required* if you want to build a toolchain based on eglibc.
# 21:30:44 y_morin sangelion: those missing is not a failure, it's just gonna disable features in crosstool-NG.
# 21:31:56 sangelion y_morin.. thanks for your help.. my build process already success.. :D
# 21:32:10 y_morin sangelion: Good to read! :-)
# 21:32:52 sangelion next step is to explore how to use it.. :D
# 21:33:16 y_morin sangelion: there are stuff in docs/ that explains how you can use that toolchain. ;-)
# 21:33:21 sangelion do you have some hint or tips.. :)
# 21:33:31 sangelion orait.. I will read it now..
# 21:33:40 sangelion will away for a moment..
# 21:45:59 sangelion y_morin: thanks again yann morin... need to sleep.. :D
# 21:46:03 sangelion bye all
# 21:46:15 y_morin sangelion: bye (going to sleep too!)
