what's the correct way to add a user to an extra group in a recipe? should the recipe also create this group, just in case? Normally some other recipe creates this. Using GROUPMEMS seems to trigger race conditions and build sometimes fails

Hi guys, does the building of container-image is working on Yocto? I have a mixed of embedded board and software docker and i would avoid mixing recipes.
<cperon>
Is it something doable ?
<cperon>
I checked at IMAGE_FSTYPES = "container" but it seems to fails due to empty kernel-source

cperon: set the kernel provider to linux-dummy
<rburton>
no point building kernel modules in a system where you can't load modules...
<rburton>
cperon: guessing you turned on cryptodev in openssl? if you actually want that and assume the host kernel has the features enabled, then you'll need to provide a dummy cryptodev recipe
<cperon>
Ok thanks will check, but I don't remember doing that :)

Hi, does anyone know how to install a GCC 9 libraries in my yocto image?
<Guest88>
I cant find the resources on how to do it
<rburton>
what do you mean by "gcc 9 libraries"?
<Guest88>
I am receiving this error /usr/lib/libstdc++.so.6: version 'GLIBXCC_3.4.26' not found
<Guest88>
suggesting that I don't have the correct libraries
BoJalling has quit [Ping timeout: 246 seconds]
<rburton>
are you trying to run a prebuild binary?
<Guest88>
yes
BoJalling has joined #yocto
<Guest88>
how would I go about to fix it?
<rburton>
the easy answer is you don't use a prebuilt binary. did you buy that binary or did another part of your company build it?
<Guest88>
I build the binary, that uses the c++17 library
<Guest88>
before this I was able to use the prebuild binary
<rburton>
build the binary with a yocto recipe, what you've done is build it using a newer copy of libstdc++ than you're trying to ship
<rburton>
when you built it you had libstdc++ 3.4.26 on your machine. now in the yocto you're using you don't. that, obviously, will fail.
<Guest88>
okay, how would I update libstdc++
<Guest88>
in my yocto build
<rburton>
why can't you just write a recipe to build the app inside yocto?
<Guest88>
i want to use the c++17 filesystem
<rburton>
what version of yocto are you using?
<Guest88>
i am on zeus
<agherzan>
LetoThe2nd I don't really know much at this point as I'm mainly hailing the maintenance. I don't really run anything on it.
<agherzan>
khem might know more
<rburton>
Guest88: the zeus that was EOL three years ago? upgrade to something that is actually supported.
<Guest88>
I cannot upgrade due to company policy
<rburton>
your company policy is to use unsupported software?
<Guest88>
but we need to implement a feature that uses the c++ 17 filesystem
<Guest88>
its for legacy
<rburton>
you "just" uprade glibc then
<Guest88>
how would i update glibc,
<Guest88>
I cant figure out how to do that
<rburton>
well, if company policy is 'no upgrading past zeus' then 'upgrading glibc' will be a violation of the spirit if not the letter
<rburton>
i guess you could statically link and hope for the best
<Guest88>
so basically i the shortcut way (not recommended) is to statically link glibc right?
<rburton>
you can try that
<rburton>
if company policy is to keep on a stable albeit very dead release of yocto, just going in and performing deep surgery to upgrade glibc should make people furious
<zwelch>
not a yocto question, but i expect folks here might have seen it: trying to git clone a repository managed by the repo tool is suddenly failing for me with "failed to start iterator over .../.git/objects". This is part of some automation that was working a week ago, and the objects directory exists indirectly through a couple of symlinks. Any ideas or workarounds?
<neverpanic>
Guest88: Word of warning: If that binary also links to other libraries that use C++ (possibly using a different libstdc++), you may end up seeing seemingly random crashes.
<rburton>
yeah its a terrible idea
<RP>
zwelch: there is discussion on the bitbake list
<zwelch>
RP: thanks!
<Guest88>
noted, thanks for advice, neverpanic and rburton will probably go back to the drawing board
<Guest88>
rburton lets say my appplication also uses the c++ boost library, I should build my application with a recipe file rather building it separately?
<rburton>
Guest88: if you _need_ a newer libstdc++ than zeus but also _need_ to use zeus, you've got problems and something needs to give
<zwelch>
RP (and others that might be lurking): I found the recent thread "discussion: git fetcher..." and discovered my solution therein; i added --no-local to my git clone command, and now it works. Thanks again!
<neverpanic>
Guest88: Sounds like you need to ship a container with a newer libstdc++ *ducks&covers*

I have this weird problem:

<dash_hope>
meta/conf/bitbake.conf. -- here also the same variable is set as x ?= "yes"
<dash_hope>
When I am printing the variable using -e, I see it is being set as "yes".

meta-abc-def has priority of 6 and meta has priority of 5.

hi, i added "dtparam=ant2" to "RPI_EXTRA_CONFIG" for activate the external antenna in meta-raspberrypi(dunfell). when i check with "cat /sys/kernel/debug/gpio" command, i can't see the relevant pin as high. but i can see it in kirkstone.
<dash_hope>
kergoth: meta-abc-def/meta-abc-xyz/conf/machine/device.conf -- i see with -e output that this file is not getting parsed and only "meta/conf/bitbake.conf." this file is there for that variable. Wondering why?

Guest88: zeus is built with gcc 9.2 and GLIBXCC_3.4.26 is defined in libstdc++ coming with gcc9 so I am not sure what is wrong. c++17 should work fine with gcc9 check https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2017, whats the toolchain you are using externally to build your app ? which gcc/glibc version does it use

also check whats the full version of installed libcstdc++ on your target find /usr -name libstdc++.so.6.0.*
