| # 11:41:17 | Net147 | joins #crosstool-ng |
| # 11:56:20 | smartin | LeZerb: yes, that a canadian cross-toolchain |
| # 11:57:44 | smartin | s/that a/that's a/ |
| # 12:02:20 | LeZerb | i read about that on the homepage - but i don't get how it is configured |
| # 12:02:47 | LeZerb | there does not seem to be an option in menuconfig |
| # 12:53:24 | smartin | LeZerb: you have to enable experimental stuff to be able to build canadian cross-compiler |
| # 12:54:39 | smartin | then select canadian as toolchain type |

| # 21:32:20 | Cilyan | Hi everyone |
| # 21:32:44 | Cilyan | I have a build failure in pmpfr due to automake 1.12 |
| # 21:33:06 | Cilyan | I have a patch to correct it, how do I make crosstool to apply it ? |
| # 21:51:07 | y_morin | Cilyan: what's your issue with MPFR? (paste-bin the corresponding part of build.log) |
| # 21:51:30 | y_morin | Cilyan: put your patch in patches/mpfr/VERSION/XXX-description.patch |
| # 21:52:36 | y_morin | Cilyan: then remove the .build/src/mpfr-VERSION directory and the .build/src/.mpfr.* files |
| # 21:53:16 | y_morin | Cilyan: and be sure to post your patch to the mailing-list, so it is included in the next version! |
| # 21:53:17 | y_morin | ;-) |
| # 21:53:50 | Cilyan | the build.log is gone, as I patched the sources myself, but I'll try your solution whichh seems cleaner |
| # 21:54:37 | Cilyan | The problem is the use in mpfr 2.4.2 of ansi2kr, a feature that was removed in automake 1.12 |
| # 21:55:10 | y_morin | Cilyan: what's your distribution? |
| # 21:55:12 | Cilyan | patch is trivial, but the one I used is missing something, I need to recreate a new patch myself, and will surely publish it if you want |
| # 21:55:17 | Cilyan | archlinux |
| # 21:55:31 | Cilyan | targetting an arm |
| # 21:55:35 | y_morin | Cilyan: OK, rolling release. Debian stable still has 1.11.1. |
| # 21:55:43 | y_morin | (automake 1.11.1) |
| # 21:55:46 | Cilyan | always bleeding edge ;) |
| # 21:55:49 | y_morin | :-) |
| # 21:56:05 | Cilyan | always first to have compatibility bugs, also... |
| # 21:56:14 | y_morin | Cilyan: yes, send it to the list, please. At least, it will get more eyes. |
| # 21:56:21 | y_morin | Yep... :-/ |
| # 21:56:45 | Cilyan | now ppl build failures... it's endless :) |
| # 21:57:41 | Cilyan | when you say patches/mpfr/VERSION/XXX-description.patch you mean from the build tree or in the crosstool installation tree ? |
| # 21:58:23 | y_morin | Cilyan: it depends on how you ran crosstool-NG's ./configure. Did you use the --enable-local flag? |
| # 21:59:21 | Cilyan | hmm... don't think so http://pastebin.com/k7hM3mVZ |
| # 22:00:05 | y_morin | Cilyan: OK, you use the package from archlinux. So, you have two options: |
| # 22:00:21 | y_morin | Cilyan: 1) ad the patch in ct-ng build-tree are rebuild it |
| # 22:00:51 | y_morin | Cilyan: 2) manually copy the patch in ct-ng's install path (probably /usr/lib/ct-ng/VERSION/....) |
| # 22:01:19 | y_morin | Cilyan: option 1 is cleaner, but option 2 might be simpler. |
| # 22:01:21 | Cilyan | ok, option 2 ATM then ;) |
| # 22:01:25 | y_morin | :-) |
| # 22:02:11 | Cilyan | would it be possible that crosstool apply local patches |
| # 22:03:07 | y_morin | Cilyan: yes, there's an option for that in the menuconfig |
| # 22:03:31 | Cilyan | I mean adding a patch to ${CT_TOP_DIR}/patch/mpfr/2.4.2/ would make crosstool apply the patch together with its own ? |
| # 22:04:27 | y_morin | Cilyan: yep, you can do that if you tell ct-ng to: |
| # 22:04:38 | y_morin | (just a sec, I run a new menuconfig to get you there...) |
| # 22:05:56 | y_morin | Paths and misc options ---> Patches origin (Bundled, then local) ---> (${CT_TOP_DIR}/patches) Local patch directory |
| # 22:06:04 | y_morin | Cilyan: ^^^^ Should do the trick |
| # 22:06:12 | Cilyan | Ah, indeed |
| # 22:06:36 | Cilyan | I saw that the first time... and forgot when I applied the real config |
| # 22:13:29 | Cilyan | works :) |
| # 22:13:34 | Cilyan | is happy |
| # 22:13:52 | y_morin | Cilyan: Good to know! :-) |
| # 22:14:39 | Cilyan | http://pastebin.com/PkARh0wt |
| # 22:17:03 | y_morin | Die, ansi2knr. Die! ;-] |
| # 22:17:46 | Cilyan | Making old tools work on newer systems is always a pain in the... where you know... |
| # 22:18:21 | y_morin | .. your ;ost sensible body part? ;-) |
| # 22:19:07 | y_morin | Cilyan: to be noted, GMP already removed it two years ago: http://gmplib.org/list-archives/gmp-commit/2010-November/000403.html |
| # 22:20:35 | Cilyan | probably the last version of mpfr also did it, but 2.4.2 is an old man... |
| # 22:21:26 | y_morin | Cilyan: can't you use a newer version of MPFR ? |
| # 22:21:41 | y_morin | Cilyan: in ct-ng, you can use up to 3.1.0 |
| # 22:22:25 | Cilyan | To be honnest I'm totally new to crosscompiling, so I do not yet really understand what should be host related and what should be target related |
| # 22:22:33 | Cilyan | I took the same libraries as the target |
| # 22:22:41 | Cilyan | and target is using mpfr 2.4.2 |
| # 22:23:31 | Cilyan | but maybe I'd better using a newer version, but when doing my testings, I had a compile problem with CLooG |
| # 22:23:48 | Cilyan | so I decided to strictly stick to what I have on the target |
| # 22:24:05 | Cilyan | In the hope the versions would be compatible |
| # 22:24:21 | y_morin | Cilyan: in ct-ng the companion libs (gmp, mpfr et al.) are host-related only. |
| # 22:24:33 | y_morin | Cilyan: there is no relation to whatever is on your target. |
| # 22:24:52 | y_morin | is so sleepy his heads falls on the keyboard... |
| # 22:25:13 | Cilyan | even if I plan to rebuild for example only a kernel and hope it will run on my target without changing anything ? |
| # 22:25:22 | y_morin | Cilyan: yep. |
| # 22:25:50 | Cilyan | and there isn't any compatibility problems to expect ? |
| # 22:26:42 | Cilyan | I mean I need gcc 4.4.5, how to be sure that the companions in never versions will be compatible ? |
| # 22:27:15 | y_morin | Cilyan: nope. The companion libs are used by gcc for compile-time duties: complex handling, optimising loops, and so on... |
| # 22:27:35 | y_morin | Cilyan: so there is virtually no impact on what rns on the target |
| # 22:28:06 | Cilyan | on the target, yes |
| # 22:28:38 | Cilyan | but on the tests I run before, it seemed that this version of gcc did not agree with newer versions of ppl |
| # 22:29:15 | y_morin | Cilyan: yep, not-so-recent versions of gcc want a 2.4.x MPFR, IIRC. |
| # 22:29:32 | y_morin | Cilyan: you could upgrade your gcc. |
| # 22:29:35 | y_morin | thinks he's gonna go to bed in short order... |
| # 22:29:52 | Cilyan | yep, I let you go to bed, and I'll better do too myself |
| # 22:30:05 | y_morin | Cilyan: DE ? |
| # 22:30:11 | Cilyan | upgrading gcc is not an option, because the running system on the target is fixed |
| # 22:30:19 | Cilyan | yes, but french ;) |
| # 22:30:27 | y_morin | Hehe! :-) |
