Apr 09 14:37:41 <dv_> a bbappend here appends to DEPENDS and EXTRA_OECONF. however, I want to make sure this is done only for the target version of the package, not the native one.
Apr 09 14:37:45 <dv_> how can I do that?
Apr 09 14:48:46 <obi> dv_: DEPENDS_append_class-target = " ..."
Apr 09 14:55:28 <dv_> thx
Apr 09 18:05:05 <ryantrinkle> is this an appropriate place to ask questions about bitbake?
Apr 09 18:05:26 <kergoth> yes
Apr 09 18:05:27 <Crofton> sure
Apr 09 18:07:17 <ryantrinkle> so, i'm trying to build something with bitbake on NixOS, and NixOS is a bit quirky in that it doesn't have a /bin/bash
Apr 09 18:07:36 <ryantrinkle> everything seems to be looking for that, so I was wondering how I can provide an explicit path for bash
Apr 09 18:07:44 <ryantrinkle> ideally in some sort of global way across everything bitbake is building
Apr 09 18:08:00 <kergoth> our recipes just run the underlying tools
Apr 09 18:08:02 <kergoth> make, autoconf, etc
Apr 09 18:08:16 <kergoth> i doubt we have the level of control you want to change how the underlying buildsystems are looking for bash if and when they want it
Apr 09 18:08:25 <kergoth> for ourselves, we use /bin/sh, not /bin/bash
Apr 09 18:08:30 <kergoth> so it's only the underlying buildsystems that might require it
Apr 09 18:08:30 <ryantrinkle> got it; so environment should pass through?
Apr 09 18:08:37 <ryantrinkle> yup, nixos has that :)
Apr 09 18:08:42 <kergoth> environment *variables* are filtered, but other than that, yes
Apr 09 18:09:25 <ryantrinkle> ah, so if i wanted to some environment variables to not be filtered, or to be explicitly provided, is that possible?
Apr 09 18:09:34 <ryantrinkle> (or maybe that's the wrong approach generally?)
Apr 09 18:10:07 <kergoth> you can, yes, by setting BB_ENV_EXTRAWHITE in the shell environment, after sourcing the setup scripts (as they set it)
Apr 09 18:10:12 <kergoth> s/setting/appending to/
Apr 09 18:10:21 <kergoth> i.e. BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE MY_EXTRA_VARIABLE"
Apr 09 18:10:32 <kergoth> this will let MY_EXTRA_VARIABLE into bitbake's metadata
Apr 09 18:10:55 <kergoth> it won't re-export it into the buildsystems we call unless you explicitly use 'export' in local.conf or similar, but that would make it available for use inside EXTRA_OEMAKE
Apr 09 18:11:21 <kergoth> that said, if you're just trying to muck with SHELL, i wouldn't advise it
Apr 09 18:12:48 <ryantrinkle> hm, yeah, that makes sense
Apr 09 18:15:27 <ryantrinkle> would there be a better way to set the shell?
Apr 09 18:15:43 <ryantrinkle> or maybe to prepend to the path that the packages see?
Apr 09 18:16:04 <ryantrinkle> i'm not sure how autoconf/etc. actually go about trying to find bash
