| # 18:39:30 | ccole | Can I use crosstool-ng to build a native ARM toolchain? |
| # 18:41:18 | y_morin | ccole: "native" as in "runs on the target" ? |
| # 18:41:28 | y_morin | ccole: no, it's not supported for now... |
| # 18:43:18 | ccole | y_morin: Yes, runs on target. |
| # 18:43:52 | ccole | y_morin: I had two people in my organization here ask for a native toolchain just this week. Sounds like its gonna be on my task list soon.. |
| # 18:44:56 | ccole | y_morin: Ideally, I'd like to mirror the same toolchain source (and crosstool-ng scripts) and settings for the native toolchain, so it is a perfact match to the cross-coolchain in terms of functionality (and bugs, if applicable) |
| # 18:45:15 | y_morin | ccole: there are currently limitations in crostool-NG that prevent building a cross-native toolchain: no support for DESTDIR, and untested non-sysroot behavior. |
| # 18:45:25 | y_morin | ccole: yes, I understand that! :-) |
| # 18:45:51 | ccole | y_morin: Any words of advice before I set out on this expedition? Like some tips, or else "dont even try it"? |
| # 18:45:54 | y_morin | ccole: fact is, for a native toolchain, you do not want sysroot, and I never ever tested how it would behave... |
| # 18:46:46 | y_morin | ccole: first step: add DESTDIR support, and fixup existing confusion in the scripts (at the beginning, I used DESTDIR or PREFIX interchangeably. Ugly). |
| # 18:47:19 | y_morin | ccole: second: use the --with-build-sysroot option to gcc's ./configure. |
| # 18:48:38 | y_morin | ccole: third step: Hmmm. Vacations, and a consultation to the therapist... :-] |

| # 19:24:45 | imMute | y_morin|away: isn't ccole asking for a Canadian Cross? |
| # 19:29:39 | imMute | well, canadian where build=x86 and host=target=arm |
| # 19:54:42 | y_morin|away | is now known as: y_morin |
| # 19:55:35 | y_morin | imMute: no, ccole (from what I understood) wants a native toolchain on the board. |
| # 19:55:59 | y_morin | imMute: Which is in fact a type of canadian-cross, granted, but a true one. |
| # 20:01:11 | ccole | y_morin: Thanks for the procedure outline. I will do this. |
| # 20:04:50 | ccole | imMute: I'm looking to build a native toolchain. This is not a Canadian Cross - that would be if I were to build a cross-compiler for a machine other than the host on which its built. |
| # 20:08:01 | y_morin | ccole: well, you want to cross-build a native toolchain. crosstool-NG calls that a cros-native (but there is no official terminology). |
| # 20:11:16 | y_morin | ccole: and this is a degenerat form of canadian-cross. |
| # 20:11:47 | y_morin | One could see the canadian-cross as the normalised form, where build != host != target != build |
| # 20:12:37 | y_morin | And all other conbination as more-or-less degenerative forms of canadian, where any two more of {build,host,target} are equal. |
| # 20:12:54 | y_morin | *any two or more... |
