hello. has anyone used the `meta-nvidia` layer before? it doesn't appear to be yocto project certified but a client is needing it for a project
<nickwhitlock>
I have it configured just as the README suggests. I'm using `poky` and I added the layers that I needed with bitbake (`git://git.openembedded.org/meta-openembedded`, `git://git.yoctoproject.org/meta-virtualization` under `nanbield`) - it's complaining about the following:
<nickwhitlock>
ERROR: Nothing PROVIDES 'virtual/libgl' (but /home/test/poky/meta/recipes-graphics/libepoxy/libepoxy_1.5.10.bb, /home/test/poky/meta/recipes-graphics/cairo/cairo_1.16.0.bb DEPENDS on or otherwise requires it)
<nickwhitlock>
mesa-gl PROVIDES virtual/libgl but was skipped: PREFERRED_PROVIDER_virtual/libgl set to libglvnd, not mesa-gl
<nickwhitlock>
libglvnd PROVIDES virtual/libgl but was skipped: PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not libglvnd
<nickwhitlock>
NOTE: Runtime target 'matchbox-terminal' is unbuildable, removing...
<nickwhitlock>
Judging from the logs, it looks like the solution involves adding `libglvnd` as the preferred provider for `libgles2`. I did this, and a bunch of other problems came up.

Would this be a question better suited for the mailing list?
<rburton>
nickwhitlock: better suited to mailing the maintainer or meta-nvidia or filing a bug in their github
<nickwhitlock>
unfortunately it looks like their github doesn't have an Issues tracker on it, but I can try reaching out to the maintainer of that repository specifically and seeing.
<nickwhitlock>
Thanks!
<rburton>
yeah i'd just mail him

rburton: yeah much posh around here ;-)
<LetoThe2nd>
that was really weird, it seems that Twitch lost the connection 15 times - I have 16 recordings in the log now.
<nickwhitlock>
Hypothetically if I were to adjust the layers myself to fix the problem, what would I need to look into?
<nickwhitlock>
Because the issue here seems to be that the .rpm for the nvidia recipe (this uses RPMs??) is linking against stuff that doesn't even seem to exist.
<nickwhitlock>
When I am in my build directory and do `grep -sr libwayland-client ../meta*`, all I'm seeing are references to: `../meta/lib/oeqa/files/buildhistory_filelist2.txt` and filelist1.txt
<nickwhitlock>
I'm specifically saying in my `local.conf` also to not even build wayland.

<kanavin>
nickwhitlock, the readme specifically instructs:
<kanavin>
there's also 'PREFERRED_PROVIDER_virtual/libgles2 set to mesa, not libglvnd'
<kanavin>
I suspect you need to set that accordingly
<kanavin>
in general, if 'a client' is using nvidia, they should ask nvidia to provide yocto support in the form of a well maintained layer
florian__ has quit [Ping timeout: 256 seconds]
<kanavin>
and not leave it to volunteers hobbyists and independent consultants
<rburton>
yeah, every customer of nvidia that uses yocto should make it very clear to nvidia that they're using yocto and want proper support
goliath has quit [Quit: SIGSEGV]
<nickwhitlock>
yeah, so i set the fields indicated in local.conf. They don't explicitly call it out in that README.md but I also set `PREFERRED_PROVIDER_virtual/libgles2` to `libglvnd`. They do mention `libgles1` and `libgles3` though.
<nickwhitlock>
When I do that, I get the issues indicated in the pastebin above
<rburton>
are you using nanbield?
<nickwhitlock>
yes
* rburton
shrugs
<rburton>
looks like nobody here uses that layer, so ask the author
<nickwhitlock>
yeah, i reached out to them over email to see if they had any ideas
<marex>
oh, the nvidia metalayer discussion ? :)
<marex>
congrats to 5.0 release, it will be awesome for sure, it already is
<nickwhitlock>
> yeah, every customer of nvidia that uses yocto should make it very clear to nvidia that they're using yocto and want proper support
<nickwhitlock>
in general yes, i agree with you
<nickwhitlock>
however, we are supplying the customer with chip-down nvidia products, so they ask us for a lot of nvidia stuff

is it possible to tell cargo-bitbake to generate a recipie for an older version of yocto?

JPEW: that would be awesome as I think that might be the worst regular failure on the autobuilder for scarthgap
<JPEW>
Needs a bitbake change, but it's not too invasive and should be able to be back ported. I can send an RFC later this week
