| RP | adelcast: let me know if you need more info from me I guess or if I can help further | 00:02 |
| adelcast | thanks RP, I quickly looked at the ticket and I think I have everything I need to fix the particular bug | 00:03 |
| adelcast | after that, I'll try to get rid of the error buffering | 00:03 |
| adelcast | I agree, that buffering is just confusing | 00:03 |
| RP | adelcast: thanks, much appreciated! | 00:03 |

| RP | adelcast: I still haven;t figured out how reproducibile builds generate empty packages but I'm not sure I want to know ;-) | 00:04 |
| adelcast | hehe, mm, well, I assume maybe those are virtual packages to group packagroups? | 00:05 |

| qschulz | bluelightning: hi, I'm trying to get qt4-embedded to compile on warrior but that does not work well ATM. I fixed builds for qemux86, qemuarm, qemuarm64 and beaglebone-yocto and one error on qemux86-64 but the latter is still failing (missing lrelease in native-sysroot) | 09:59 |
| qschulz | bluelightning: the qt4-embedded issue on warrior is because GCC v8 now refuses to compile `asm volatile` lines. As per the documentation, volatile is the default qualifier for asm so we should be good removing it | 10:00 |
| bluelightning | qschulz: ok - if you could send your patch(es) I can apply them | 10:00 |
| qschulz | however, I saw this error only in some JavascriptCore JStubs file and nowhere else even though asm volatile is present in different files | 10:01 |

| T_UNIX | jofr: thats usually the difference betwenn `DEPENDS` and `RDEPENDS`. Where `R` is short for runtime. | 12:03 |
| T_UNIX | do `A.bb` would contain a line like `DEPENDS += "B"` | 12:04 |
| jofr | Yeah, I haven't been able to fully wrap my head around that. i.e. the full relation between DEPENDS vs. RDEPENDS and then native-recipes. | 12:04 |
| T_UNIX | did you read about `cross-canadian` in the context of compilation? | 12:05 |
| jofr | Yes yes. | 12:05 |
| jofr | So in my head, native recipes are for doing basically what I want. Provide stuff that should be used at compile-time | 12:06 |
| jofr | But what then is the difference between depending and rdepending on a native recipe? | 12:06 |
| *** awe00 <awe00!~awe00@unaffiliated/awe00> has joined #yocto | 12:06 | |
| T_UNIX | usually you need the `-native` version only if you need to execute an architecture binary tool | 12:07 |
| jofr | (when I say native, I mean a recipe the classextends and is used with the -native suffix) | 12:07 |
| yocti | New news from stackoverflow: About the use of yocto toaster? <https://stackoverflow.com/questions/58933755/about-the-use-of-yocto-toaster> | 12:07 |
| T_UNIX | jofr: look at http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-core/psplash/psplash_git.bb | 12:11 |
| T_UNIX | as you can see it invokes http://git.yoctoproject.org/cgit/cgit.cgi/psplash/tree/make-image-header.sh | 12:11 |
| T_UNIX | which, in turn, invokes `gdk-pixbuf-csource` | 12:12 |
| T_UNIX | so `psplash` eventually requires `gdk-pixbuf-native`, which might `DEPENDS`ed on `libpng-native` to be built and `RDEPENDS` on `libpng-native` to execute. | 12:15 |
| T_UNIX | but at the point of executing the recipe for `psplash`, it neglects the `DEPENDS` of `gdk-pixbuf-native` and only stages the files covered by mentioned `RDEPENDS`. | 12:16 |
| T_UNIX | which - in this very case - *might* be the same. | 12:16 |
| T_UNIX | jofr: if you think about linking architecture specific applications statically, it might make more sense. | 12:18 |

| rburton | jofr: B should install its stuff into the sysroot like normal. A will depend on B, and A's sysroot has stuff from B in. | 12:22 |
| jofr | rburton: Ok. I'll make up some paths then :) | 12:22 |
| jofr | But thanks both of you :) | 12:22 |
| rburton | jofr: rdepending on a native recipe makes no sense at all | 12:23 |
| jofr | rburton: I just found out.. QA gave me a warning | 12:23 |
| rburton | (unless you're a native recipe) | 12:23 |
| rburton | jofr: so native recipes are entirely for stuff that *runs* at build time. if you've a recipe that just ships a pile of data that another recipe needs, then its still a target recipe. | 12:24 |
| T_UNIX | rburton: then, I assume, `-native` packages are depending on the corresponding `-native` version automagically? or are the handled in some parallel namespace? | 12:24 |
| rburton | not sure i understand, got a concrete example? | 12:25 |
| jofr | But for such an do_install section.. I think I might be too verbose: {D}${STAGING_DIR_NATIVE}${includedir}? | 12:25 |
| jofr | (missing $) | 12:25 |
| rburton | not STAGING_DIR_NATIVE | 12:25 |
| jofr | Aight. | 12:25 |
| rburton | install like normal, ${D}${includedir} | 12:25 |
| jofr | Thanks! | 12:25 |
| rburton | one day we'll do something awesome and lock down writes during builds so do_install can't write into directories it shouldn't be writing into | 12:26 |
| jofr | rburton: And recipe A should DEPENDS on B-native? | 12:29 |
| jofr | Or RDEPENDS on B? | 12:30 |
| T_UNIX | jofr: `-native` is not necessary if your data is not architecture specific to your build system :) | 12:30 |
| T_UNIX | jofr: do you need the data to be there, when you want to execute A on the target? | 12:30 |
| jofr | Nope. Recipe generates (among other things) a header-file that recipe A uses when building. | 12:31 |
| jofr | Nope. Recipe B generates (among other things) a header-file that recipe A uses when building. | 12:31 |
| jofr | It's a bit convoluted, I know. But those artifacts from B are required my more than recipe-A. i.e. there are multiple recipe-A's ;) | 12:32 |
| T_UNIX | then B should provide and create some `-dev` package and `A` should `DEPEND` on `B` :) | 12:33 |
| *** kaspter <kaspter!~Instantbi@222.67.188.181> has joined #yocto | 12:34 | |

| jofr | Now. A completely different problem. | 12:38 |
| jofr | Which I do have a workaround for, but I think it's ugly has hell. | 12:38 |
| jofr | I have a recipe for a custom-package. But I would like to do that build as a part of our CI-system, and that includes building for pull-requests. I'm having some SRC_URI problems, because in that case, the "Git-path" isn't a normal branch (refs/head), but rather a pull-branch (refs/pull). Anyone solved that problem before? | 12:42 |
| jofr | The branch-name (and commit-hash as well actually) is passed as an evironment variable (which I have whitelisted and all that is fine), and I have Python snippet that mangles the SRC_URI to conditionally add the "nobranch=1" if that branch-name starts with "refs/pull". | 12:44 |

| jofr | rburton: One last question. Recipe B installs its stuff to ${D}${includedir}, but what is the full-path on the other-side, from recipe-A's perspective? | 12:53 |
| jofr | ${D} isn't the same on both sides, is it? | 12:53 |
| jofr | (I wish those variables were populated in the -c devshell) | 12:54 |
| rburton | D is Destination | 12:55 |
| qschulz | jofr: it's going to be in recipe-sysroot (or recipe-sysroot-native if native package) | 12:55 |
| rburton | when installing, write to D | 12:55 |
| rburton | the include file will just be in the sysroot like every other include file | 12:56 |
| jofr | Yes.. But if I have other files where I need to specify their full path? | 12:57 |

| qschulz | is/in | 13:01 |
| rburton | jofr: note that not everything is in the sysroot by default, ie $datadir isn't included unless you tell it | 13:02 |
| jofr | Yeah, I think I should just explain the whole thing. So what I'm messing with is the u-boot-environment. I have an environment specified in a file. Then I have a Python parser that parses that file and makes it nice for a header-file which is then #defined as CONFIG_EXTRA_ENV_SETTINGS in u-boot. So what I used to do was generate that header and then copy it into ${S}/include/configs where ${S} has been defined as the WORKDIR/git for the u | 13:05 |
| jofr | -boot recipes. This header file is used by u-boot, but also for u-boot-fw-utils. | 13:05 |
| jofr | Now I've added another dependency on such an output, that one is actually not using the same parser, because the output-format needs to be slightly different, but it mangles the same u-boot-environment to make it compatible for passing to (U-Boot) fw_setenv --script (this can happed at update-time if required). That part actually doesn't need to go anywhere in the sysroot, I can just "deploy" it to the image-folder (similar to some other | 13:05 |
| jofr | final-artifacts). | 13:05 |
| jofr | So, In order not to change my u-boot build too much, I would really like to copy this header to ${S}/include/configs in U-boot.. | 13:06 |
| qschulz | why don't you use bbappends for U-Boot directly? | 13:07 |
| qschulz | put your logic in an .inc shared by both u-boot and u-boot-fw-utils and add them in bbappends so you don't duplicate code. But I feel like I'm suggesting something you didn't want or that is not fixing your issue, what am I missing? | 13:09 |

| jofr | qschulz: That's what I had at first. So I just had a "files" folder and in my bbappend, I copied my files/<custom-board>_defconfig, my files/<custom-board>.h (the one I'm talking about here), etc. into the appropriate places within ${S}. But then me and other people found it so annoying to maintain the <custom-board>.h with the #define CONFIG_EXTRA_ENV_SETTINGS, making sure that the newline-escapes (the "string" \ ) were always ok, etc. S | 13:56 |
| jofr | o I created this parser-thing that takes a nicer input, where the environment can be properly indented and so on and turns it into the string required by #define CONFIG_EXTRA_ENV_SETTINGS. | 13:56 |
| jofr | Now the update-system has gotten a little more complicated than it used to be. The update didn't update u-boot at all, and actually still doesn't, but it may require changes to the u-boot environment. So at build-time, the environment that gets compiled into the new u-boot as the default-environment, also gets output to a file that's compatible with "fw_setenv --script" so it can be used to update the u-boot-environment on the target. Tha | 13:56 |
| jofr | t required another parser, because now instead of doing the "<string>" \ business, it needs to remove newlines from each variable and so on. That environment-file/script then gets released with the update. | 13:56 |
| jofr | So what I have now is a recipe called "u-boot-extra-env-settings(.bb)" and everything that it entails. Then u-boot and u-boot-fw-utils depend on this new recipe, and that's how it now gets its <custom-board>.h file. But, then there's the update system. That's a recipe that creates a "package", which is just a zip-file that consists for the artifacts, a JSON-manifest and a update-shellscript. That recipe required this other output from "u- | 14:01 |
| jofr | boot-extra-env-settings". | 14:01 |
| jofr | s/for the artifacts/of the artifacts/ | 14:03 |

| qschulz | jofr: also, maybe you can use your u-boot-extra-env-settings binary as a native tool in your u-boot* recipes and create the header file directly in your u-boot* source code | 14:31 |

| fullstop | I am trying to be a good citizen when it comes to shared library sonames. Yocto is forcing me to do so, actually. | 19:29 |
| fullstop | In my project I am using opkg. Let's say that a project, bar, links to libfoo.1.2.so. Can I upgrade libfoo to libfoo.1.3.so (which are ABI compatible) without updating all of the packages which depend on libfoo? | 19:30 |
| fullstop | What happens to libfoo.1.2.so when the package is upgraded? | 19:30 |
| fullstop | and, yes, I mean libfoo.so.1.2 etc. | 19:31 |
| fullstop | I see for things like libglib executables link to libglib-2.0.so.0 which is a symlink to a specific version. | 19:34 |
| fray | if it's compatible, then the new version needs to provide BOTH 1.3 and 1.2 sonames | 19:35 |
| fray | usual failure is someone releases 1.3, with a 1.2 compatible ABI, but never defines BOTH the 1.3 and 1.2 sonames | 19:36 |
| fray | the YP build system inspects libraries, and if they're not defined right you will get dependency errors | 19:36 |
| fullstop | I will aim for that | 19:37 |
| fullstop | not the usual failure case, multiple sonames | 19:37 |
| fullstop | does that mean multiple -Wl arguments to ld? | 19:38 |
| fray | sorry I don't have an example offhand | 19:39 |
| fullstop | darn. I'll dig through recipes I guess. | 19:39 |
| fray | usuaully not recipe specific, but buried in the upstream code.. | 19:40 |
| fray | but ya, it's multiple -Wl arguments, just don't remember the format offhand | 19:40 |
| fray | gcc -shared -o libfoo.so.x.y -Wl,-soname,libfoo.so.x some_file.o ... | 19:41 |
| fray | try specifying -soname multiple times | 19:41 |
| fray | recipe processing will automatically see this, and setup everything | 19:41 |
| fullstop | I have libraries which, for better or worse, are done in a Makefile.. so I'm the buried upstream code at the moment. :-) | 19:41 |
