| # 17:27:07 | smartin | y_morin: hi |
| # 17:32:20 | smartin | about redistributing self-contained mac cross-toolchain (adding lib{gcc_s.*,sdtc++.*}.dylib to the toolchain and tweaking rpath), i cannot remember what you told me about legal issue... :/ |
| # 19:22:06 | y_morin | smartin: was it on this channel? |
| # 19:22:10 | y_morin | (Hello!) |
| # 19:22:34 | y_morin | smartin: because if so, you can search the logs. |
| # 19:23:37 | y_morin | smartin: I'll be back ~22:00 GMT+2 |
| # 19:35:06 | smartin | y_morin: back in 30 to 45min. |

| # 20:53:38 | smartin | y_morin: ping? |
| # 21:16:36 | y_morin | smartin: pong |
| # 21:23:08 | smartin | i come back about mac "self-contained" toolchains |
| # 21:23:58 | y_morin | smartin: IIRC, that's not really possible on Mac, as static linking is not possible on OS-X |
| # 21:24:35 | y_morin | At least, that's what usual Mac users told me; I have no experience about MacOS |
| # 21:24:39 | smartin | in which i add lib{gcc_s,stdc++}*.dylib and tweak rpath to make it self-contained |
| # 21:26:49 | smartin | yep, this not possible (or hard and at least not so much documented)... what a pity |
| # 21:27:49 | y_morin | smartin: OK. So, you copy NEEDED libs in the lib/ dir, and with your rpath trick, you have a self-contained toolchain, right? |
| # 21:27:56 | smartin | the 2 libs I added come from gcc package from macport |
| # 21:28:08 | smartin | yes |
| # 21:28:12 | y_morin | Right, so, what's the issue? |
| # 21:29:10 | smartin | do I have to do/add something when redistributing it? |
| # 21:30:50 | y_morin | smartin: IANAL, but you have to respect all the licenses, that is, in this this case, probably provide the source code of those libs, as well as there build script. |
| # 21:31:05 | y_morin | s/there/their/ |
| # 21:32:36 | smartin | provide the source code even for gcc from macport? |
| # 21:33:32 | y_morin | smartin: well, the source for the libs you copied. |
| # 21:34:17 | y_morin | smartin: literrally, yes, that is what the license requires. You provide a binary built from GPL or LGPL code, you have to provide a way to rebuild that binary. |
| # 21:34:59 | y_morin | smartin: Now, that a literal interpretation of the license. And IANAL. |
| # 21:35:23 | y_morin | smartin: the best bet would be *not* to provide those libs. |
| # 21:36:04 | y_morin | smartin: Aren't Macports widely available, that requiring the use to install the pre-requisites from macports too cumbersome? |
| # 21:36:46 | y_morin | smartin: I mean, in the install procedure of the toolchain, you could document to install gcc from macports, and you're done. |
| # 21:37:04 | y_morin | What's so difficult about this? |
| # 21:37:41 | y_morin | won't say what he thinks about MacOS. |
| # 21:40:11 | smartin | to use ct-ng, we need to use a gcc from macport, unfortunately, using the built toolchain on another Mac host without this gcc package installed fails... |
| # 21:40:43 | smartin | not really user-friendly... |
| # 21:42:21 | y_morin | smartin: what is it that is so difficult to require that the gcc _runtime_ be instaleld from Macports on the other co;puter)s)? |
| # 21:42:30 | y_morin | *computer(s) |
| # 21:44:42 | y_morin | smartin: after all, if I want to pass a pre-built toolchain on Linux, there will also be packages to install on the other computer(s) to run this toolchain. |
| # 21:45:00 | y_morin | (But on Linux, we do have static linking, although it is sub-optimal.) |
| # 21:46:29 | alan_o | quits : Quit: Leaving |
| # 21:47:44 | smartin | well, not really *noob*-friendly, most of the time poeple doesn't care how it works, they just want to install the software they paid for and use it |
| # 21:48:08 | smartin | preferably with no additional actions required... |
| # 21:49:33 | smartin | Not all platform take care of developers ;) |
| # 21:49:37 | y_morin | smartin: then I would say a "noob" (that's your word! ;-) ) has nothing to do with cross-compilation. |
| # 21:50:23 | y_morin | smartin: but the basic rule for gpl/lgpl covered code is: you provide a binary, you must provide means to rebuild them (and replace them for v3) |
| # 21:51:40 | smartin | but when you want to do cross-platform software and/or cross-toolchain, you have to deal with it... |
| # 21:53:31 | smartin | ok, now I know what i have to do to redistribute it |
| # 21:53:39 | smartin | thanks |
| # 21:53:59 | y_morin | Cheers! |
| # 21:58:11 | y_morin | smartin: By the way, re-readings my answers, I may seem a bit harsh. That was not my intention. |
| # 21:58:50 | smartin | y_morin: it's ok ;) |
| # 22:23:22 | y_morin | just build all 40 samples: ~90GiB for the build dirs, plus another ~8GiB for the toolchain dirs, and 6h of intensive heat disipation... |
| # 22:36:36 | y_morin | quits : Quit: Night! |
