| # 15:31:28 | dsmith-work | Howdy folks. |
| # 15:32:17 | dsmith-work | So I have that 64/32 bit build issue. Currently using 1.14.1 |
| # 15:35:51 | dsmith-work | Ahh. setarch |

| # 16:18:16 | haluk | Hi, I have a problem with with building a cross-compiler on mac os |
| # 16:19:14 | haluk | I chose eglibc-2.13 as c library and the compilation stops with: |
| # 16:19:27 | haluk | rpc_main.c:41:21: error: libintl.h: No such file or directory |
| # 16:23:31 | haluk | I didn't chose to enable nls in the config by the way |
| # 17:21:26 | y_morin | joins #crosstool-ng |
| # 17:29:48 | haluk | Hi y_morin, would it be rude if I repeated my question? |
| # 17:49:05 | y_morin | haluk: I was not onl-line, so I did not see your question. Re-post, please. |
| # 17:49:20 | haluk | I have a problem with with building a cross-compiler on mac os |
| # 17:49:28 | haluk | I chose eglibc-2.13 as c library and the compilation stops with: |
| # 17:49:35 | haluk | rpc_main.c:41:21: error: libintl.h: No such file or directory |
| # 17:49:41 | haluk | I didn't chose to enable nls in the config by the way |
| # 17:50:35 | y_morin | Well, you have your answer: MacOS! :-p |
| # 17:50:56 | y_morin | More seriously now, I don't know MacOS enough to give a straight answer. |
| # 17:51:10 | y_morin | Did you google for the error? |
| # 17:51:12 | haluk | :) So this is a desperate case? |
| # 17:51:48 | y_morin | haluk: no. Did you install gettext? |
| # 17:51:57 | haluk | Yes, the only this relevent I have found was an IRC log on #crosstool-ng channel |
| # 17:52:13 | y_morin | haluk: http://www.lists.apple.com/archives/Unix-porting/2006/Feb/msg00095.html |
| # 17:52:14 | haluk | *this -> thing |
| # 17:52:51 | haluk | Uhm, let me have a look |
| # 17:53:33 | y_morin | haluk: can you put your build.log on some pastebin? (or an ftp/http server where I can get it) |
| # 18:04:30 | haluk | you mean *all* of it? |
| # 18:06:44 | y_morin | haluk: yes. But do not post to ML. |
| # 18:06:57 | y_morin | haluk: got to go for dinner. Back in ~1h |
| # 18:07:27 | haluk | ok, I have posted it in pastebin but still waiting for it to get uploaded |
| # 18:16:19 | haluk | It won't work this way I'll find another way |
| # 18:23:20 | haluk | y_morin: Well, I have uploaded it to GDrive: https://docs.google.com/open?id=0B-n6Fa7y3EScM2NrR2FDYnp4WFk |
| # 18:30:09 | smartin | hi all, |
| # 18:33:22 | smartin | haluk: don't know if it is related or not, but last time i tweak gettext in buildroot, libintl was not built if i had not enabled locale support... |
| # 18:39:46 | haluk | smartin: So you suppose enabling "Build and install locales" in C library config? |
| # 18:40:59 | smartin | haluk: that's what I would try |
| # 18:43:02 | haluk | smartin: OK, why not? I'm gonna start a build with locale support and go eat someting :) |

| # 18:59:39 | dsmith-work | So is there any "fix" for building on a 64bit capable os with only 32bit libs available? Other than "setarch i686" ? |
| # 19:46:50 | smartin | joins #crosstool-ng |
| # 20:39:30 | neure | joins #crosstool-ng |
| # 20:39:32 | neure | hello |
| # 20:40:03 | neure | i keep getting could not retrieve 'eglibc-2_15' |
| # 20:40:22 | neure | i am trying to build cross compiler targetting raspberry pi |
| # 20:52:33 | neure | doh |
| # 20:52:40 | neure | i had not installed svn |
| # 20:52:53 | neure | i suppose i need to rebuild crosstool? |
| # 20:57:13 | dsmith-work | so the eglibc people do not provide tarballs? |
| # 20:57:34 | neure | not sure about that |
| # 20:57:44 | neure | but the default setting needs svn |
| # 20:57:50 | neure | so i simply installed it |
| # 21:23:55 | y_morin | dsmith-work: no "fix". I believe the proper way is to use setarch. |
| # 21:24:18 | y_morin | dsmith-work: no, eglibc does not do tarball releases. |
| # 21:24:42 | y_morin | neure: yes, svn is required to use eglibc, for the reason just above. |
| # 21:24:53 | y_morin | Ah. haluk is gone.... :-/ |
| # 21:28:40 | dsmith-work | y_morin: Thanks |
| # 21:29:56 | y_morin | dsmith-work: in fact, the real, real fix would be to make the offending ./configure (was that ppl's?) properly detect the situation. |
| # 21:30:02 | y_morin | Maybe upstream has a fix for that. |
| # 21:30:21 | y_morin | dsmith-work: can you confirm the lib that breaks without setarch (can't remember) |
| # 21:30:25 | y_morin | ? |
| # 21:34:02 | dsmith-work | I had issues with gmp |
| # 21:34:18 | dsmith-work | Not sure if there is more beyond that. |
| # 21:35:20 | neure | hmmh it _is_ taking a while to build the toolchain :P |
| # 21:35:22 | dsmith-work | My build machine is a, well, something like a fbdsd "jail". It's 32bit, but running on a 64bit host. |
| # 21:36:02 | y_morin | dsmith-work: yep, gmp is the culprit. |
| # 21:36:51 | y_morin | neure: here, a full toolchain with C,C++,java,fortran takes ~45 minutes. Hexa-core i7 with lotta RAM and fast HDD. |
| # 21:36:52 | dsmith-work | [CFG ] checking size of mp_limb_t... 4 |
| # 21:36:52 | dsmith-work | [ERROR] configure: error: Oops, mp_limb_t is 32 bits, but the assembler code |
| # 21:36:52 | dsmith-work | [CFG ] in this configuration expects 64 bits. |
| # 21:36:52 | dsmith-work | |
| # 21:37:23 | dsmith-work | THat's the error. |
| # 21:37:26 | y_morin | dsmith-work: that is the usual error that setarch should fix, right? Or do you stil get the error with setarch? |
| # 21:37:54 | dsmith-work | Yep. THat's the usual error I think. setarch works fine for me. |
| # 21:38:21 | y_morin | dsmith-work: OK. Thanks for the heads up!. |
| # 21:38:23 | y_morin | dsmith-work: what do you mean by a "fbdsd" jail? |
| # 21:39:08 | neure | y_morin, i've got Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz in virtual box with 2GB :P |
| # 21:39:20 | dsmith-work | It's kind of like a chroot but moreso. |
| # 21:39:47 | dsmith-work | I didn't set the machines up. |
| # 21:39:52 | y_morin | neure: that is a pretty decent machine, except for the VM stuff that probably costs you a lot in overhead... |
| # 21:39:57 | dsmith-work | So I'm a bit vague.. |
| # 21:40:02 | y_morin | dsmith-work: more like the bsd jails, then? |
| # 21:40:20 | y_morin | dsmith-work: or like an LXC ? |
| # 21:40:32 | neure | y_morin, i do have ssd though |
| # 21:40:48 | neure | i'd imagine that helps compiling stuff |
| # 21:41:33 | neure | hmm |
| # 21:41:38 | neure | actually looks like it's stuck |
| # 21:41:42 | neure | no |
| # 21:41:43 | dsmith-work | It's a linux vserver |
| # 21:41:46 | y_morin | neure: well, I would not be surprised by a ~15% overhead nonetheless, is only due to: VM overhead + low memory. |
| # 21:41:49 | neure | it just updates the time slowly |
| # 21:42:03 | y_morin | dsmith-work: Ah. vserver is like LXC. |
| # 21:42:07 | neure | i could have assigned more memory to it, ive got 8GB in host |
| # 21:42:28 | neure | whats PPL? |
| # 21:43:12 | y_morin | neure: on my machine, I run 12 jobs in // and I topped at ~10GiB memory use at one time when compiling PPL, so that is roughly 1GiB per job. |
| # 21:43:24 | y_morin | neure: PPL is Parma Polyhedral Library. |
| # 21:43:41 | y_morin | Helps gcc does fancy stuff to loops: unrolling, splitting, inversions... |
| # 21:43:41 | neure | what is that used for? |
| # 21:43:45 | neure | ok |
| # 21:44:03 | neure | does crosstool support only gcc? |
| # 21:44:11 | neure | is how about clang? |
| # 21:44:15 | neure | -is |
| # 21:44:28 | y_morin | neure: yes. That is basically the only /complete/ compiler out there. |
| # 21:44:38 | y_morin | neure: clang is not yet ready for x-compilation. |
| # 21:44:44 | neure | no? |
| # 21:44:46 | neure | :-( |
| # 21:45:34 | y_morin | neure: clang/llvm is a very neat piece of stuff, and I am really eager to see them progress to the point we have a viable alternative (not necessarily a replacement) to gcc. |
| # 21:45:56 | y_morin | neure: but afaik, clang only really supports x-compilation on MacOS for iStuff. |
| # 21:46:26 | y_morin | neure: there was an article on lwn.net recently about that (IIRC, maybe it was some place else...) |
| # 21:47:34 | neure | mmh right |
| # 21:47:39 | neure | apple has universal binaries too |
| # 21:51:29 | neure | apt-get install clang .. on raspberry pi.. |
| # 21:51:33 | neure | this will be interesting |
| # 21:51:50 | dsmith-work | Hmm. I wonder if lxc has the same issue as vserver. Probably does, as I think both are just different userlands running under a common kernel. |
| # 21:53:35 | y_morin | dsmith-work: yes. |
| # 21:54:25 | y_morin | dsmith-work: there is however another (more ugly IMHO) trick: provide a fake 'uname' that return i686 instead of x96_64. |
| # 21:54:39 | y_morin | x86_64, 96... |
| # 21:54:45 | y_morin | Bah... |
| # 21:57:04 | y_morin | dsmith-work: http://mirror.linux.org.au/linux/kernel/people/ak/uname26/ |
| # 21:58:13 | y_morin | dsmith-work: well, it's not the one I wanted to point to, my bad. |
| # 21:58:17 | dsmith-work | y_morin: That's basically what setarch does, right? |
| # 21:58:31 | dsmith-work | (re fake unname) |
| # 21:58:49 | y_morin | dsmith-work: nope, than one is about faking a linux-2.6.x kernel on a linux-3.x kernel. |
| # 21:58:58 | dsmith-work | $ uname -m |
| # 21:58:58 | dsmith-work | x86_64 |
| # 21:58:58 | dsmith-work | |
| # 21:59:07 | y_morin | dsmith-work: and the uname I thought about would be: |
| # 21:59:15 | dsmith-work | $ setarch i686 uname -m |
| # 21:59:15 | dsmith-work | i686 |
| # 21:59:15 | dsmith-work | |
| # 21:59:32 | y_morin | dsmith-work: yes, the same result, but using: |
| # 21:59:45 | y_morin | $ uname-32 |
| # 21:59:47 | y_morin | i686 |
| # 22:00:02 | y_morin | And then one would symlink or alias uname to this uname-32 |
| # 22:00:13 | dsmith-work | yeah |
| # 22:00:34 | y_morin | dsmith-work: setarch is IMHO better in that it uses the Linux kernel personality. |
| # 22:16:31 | smartin | quits |
| # 22:21:34 | dsmith-work | y_morin: Hmm. I could probably just put script that is somehting like '#!/bin/sh\nexec setarch i686 /usr/bin/uname.real "$@"' at /usr/bin/uname |
| # 22:21:53 | neure | haha |
| # 22:22:10 | neure | after 79 mins crosstool ng tells me oops, you dont have awk :D |
| # 22:22:19 | neure | would be worth configure to check |
| # 22:22:21 | dsmith-work | heh |
| # 22:22:40 | y_morin | dsmith-work: probably, but then you won't be ablo to build 64-bit binaries (but you only have 32-bit userland, right?) |
| # 22:22:54 | y_morin | neure: there's already a check for GNU awk in .configure. |
| # 22:23:58 | y_morin | neure: what's your host machine? |
| # 22:24:13 | y_morin | neure: what's the output of: awk --version |
| # 22:25:43 | y_morin | neure: when I was building my first toolchains, I would wait for someting like 3 hours for a full C,C++ toolchain! |
| # 22:26:18 | y_morin | So 80 minutes is nto that much! :-] |
| # 22:30:45 | dsmith-work | y_morin: Right. |
| # 23:13:20 | neure | y_morin, ubuntu 12.04 |
| # 23:13:33 | neure | and sorry but i had already installed gawk |
| # 23:13:51 | neure | so idk what awk --version would have said before i did |
| # 23:14:06 | neure | oh wait no |
| # 23:14:33 | y_morin | neure: probably something like: |
| # 23:14:36 | y_morin | awk --version |
| # 23:14:38 | y_morin | mawk: not an option: --version |
| # 23:14:41 | neure | tes |
| # 23:14:42 | neure | yes |
| # 23:14:45 | neure | that's what it says |
| # 23:15:12 | y_morin | Becasue Debian and Debian derivative install mawk as the default awk, and do not install GNU awk. |
| # 23:15:25 | neure | file `which awk` says "/usr/bin/awk: symbolic link to `/etc/alternatives/awk'" |
| # 23:15:25 | y_morin | And glibc (IIRC) requires GNU awk, and does not work with mawk. |
| # 23:15:44 | y_morin | neure: yes, that's standard Debian alternatives. |
| # 23:15:56 | neure | ok |
| # 23:16:12 | neure | so configure needs a bit more extra tests |
| # 23:16:14 | y_morin | neure: I'll had a more thourough check in configure... But not now, it's 1:15 am here |
| # 23:16:20 | y_morin | had -> add. |
| # 23:16:30 | neure | one hour less here :P |
| # 23:16:33 | y_morin | (which is really an indication I should get some sleep!) |
| # 23:17:04 | neure | and i was doing apt-get install gawk on raspberry :D |
| # 23:17:09 | y_morin | neure: GB? |
| # 23:17:09 | neure | where it fails.. |
| # 23:17:11 | neure | yeah |
| # 23:17:51 | y_morin | neure: you mean, you are trying to run ct-ng on RaspberryPi? |
| # 23:17:57 | neure | no |
| # 23:18:05 | neure | i just used wrong shell window |
| # 23:18:17 | y_morin | Oh! Get soem sleep too, then! ;-) |
| # 23:18:31 | neure | sounds like a good idea |
| # 23:18:37 | y_morin | :-) |
| # 23:18:43 | neure | would still like to see what the next issues is going to be :P |
| # 23:19:29 | y_morin | neure: what was the step that failed requiring GNU awk? |
| # 23:19:43 | neure | [INFO ] Installing C library headers & start files |
| # 23:19:43 | neure | [ERROR] configure: error: GLIBC requires GNU awk. |
| # 23:19:45 | neure | what |
| # 23:19:53 | neure | does build always start from scratch? |
| # 23:20:05 | y_morin | neure: yes, by default. |
| # 23:20:28 | neure | that does not sound very good when each cycle takes 80 minutes :D |
| # 23:20:35 | y_morin | neure: that's becasue ct-ng (the build scripts) have no way to know if a previous build was successful or not. |
| # 23:20:37 | dsmith-work | Very painful that. |
| # 23:20:45 | y_morin | *because |
| # 23:20:52 | neure | why not add some state tracking?) |
| # 23:21:12 | y_morin | There is a possibility. See the doc, it explains how to stop and restart a step |
| # 23:21:19 | dsmith-work | You know, that's what make is for..... |
| # 23:21:29 | dsmith-work | y_morin: jk |
| # 23:21:48 | y_morin | dsmith-work: yes, but there is no dpeendency between the components, make-wise. |
| # 23:23:18 | y_morin | Well, guys, nice to speak, but my eyes are closing on their own will. I must go get some rest. |
| # 23:23:22 | y_morin | See ya! |
| # 23:23:28 | dsmith-work | Right. You need to use fake state tracking files. A pain also. |
| # 23:23:42 | y_morin | dsmith-work: right, pita. |
| # 23:23:45 | y_morin | quits : Quit: Night! |
