Compiler panic at Yocto Scarthgap build

[orascheg]

Yocto Scarthgap with pull from 29th January 2025.

local.conf:

#
# This file is your local configuration file and is where all local user settings
# are placed. The comments in this file give some guide to the options a new user
# to the system might want to change but pretty much any configuration option can
# be set in this file. More adventurous users can look at
# local.conf.sample.extended which contains other examples of configuration which
# can be placed in this file but new users likely won't need any of them
# initially. There's also site.conf.sample which contains examples of site specific
# information such as proxy server addresses.
#
# Lines starting with the '#' character are commented out and in some cases the
# default values are provided as comments to show people example syntax. Enabling
# the option is a question of removing the # character and making any change to the
# variable as required.

#
# Machine Selection
#
# You need to select a specific machine to target the build with. There are a selection
# of emulated machines available which can boot and run in the QEMU emulator:
#
#MACHINE ?= "qemuarm"
#MACHINE ?= "qemuarm64"
#MACHINE ?= "qemumips"
#MACHINE ?= "qemumips64"
#MACHINE ?= "qemuppc"
#MACHINE ?= "qemux86"
#MACHINE ?= "qemux86-64"
#
# There are also the following hardware board target machines included for 
# demonstration purposes:
#
#MACHINE ?= "beaglebone-yocto"
#MACHINE ?= "genericarm64"
#MACHINE ?= "genericx86"
#MACHINE ?= "genericx86-64"
#
# This sets the default machine to be qemux86-64 if no other machine is selected:
MACHINE ??= "intel-corei7-64"

# These are some of the more commonly used values. Looking at the files in the
# meta/conf/machine directory, or the conf/machine directory of any additional layers
# you add in will show all the available machines.

#
# Where to place downloads
#
# During a first build the system will download many different source code tarballs
# from various upstream projects. This can take a while, particularly if your network
# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
# can preserve this directory to speed up this part of subsequent builds. This directory
# is safe to share between multiple builds on the same machine too.
#
# The default is a downloads directory under TOPDIR which is the build directory.
#
DL_DIR ?= "${TOPDIR}/downloads"

#
# Where to place shared-state files
#
# BitBake has the capability to accelerate builds based on previously built output.
# This is done using "shared state" files which can be thought of as cache objects
# and this option determines where those files are placed.
#
# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
# from these files if no changes were made to the configuration. If changes were made
# to the configuration, only shared state files where the state was still valid would
# be used (done using checksums).
#
# The default is a sstate-cache directory under TOPDIR.
#
SSTATE_DIR ?= "${TOPDIR}/sstate-cache"

#
# Where to place the build output
#
# This option specifies where the bulk of the building work should be done and
# where BitBake should place its temporary files and output. Keep in mind that
# this includes the extraction and compilation of many applications and the toolchain
# which can use Gigabytes of hard disk space.
#
# The default is a tmp directory under TOPDIR.
#
TMPDIR = "${TOPDIR}/tmp"

#
# Default policy config
#
# The distribution setting controls which policy settings are used as defaults.
# The default value is fine for general Yocto project use, at least initially.
# Ultimately when creating custom policy, people will likely end up subclassing 
# these defaults.
#
DISTRO ?= "poky"
# As an example of a subclass there is a "bleeding" edge policy configuration
# where many versions are set to the absolute latest code from the upstream 
# source control systems. This is just mentioned here as an example, its not
# useful to most new users.
# DISTRO ?= "poky-bleeding"

#
# Package Management configuration
#
# This variable lists which packaging formats to enable. Multiple package backends
# can be enabled at once and the first item listed in the variable will be used
# to generate the root filesystems.
# Options are:
#  - 'package_deb' for debian style deb files
#  - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
#  - 'package_rpm' for rpm style packages
# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
# OE-Core defaults to ipkg, whilst Poky defaults to rpm:
PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"

#
# SDK target architecture
#
# This variable specifies the architecture to build SDK items for and means
# you can build the SDK packages for architectures other than the machine you are
# running the build on (i.e. building i686 packages on an x86_64 host).
# Supported values are i686, x86_64, aarch64
#SDKMACHINE ?= "i686"

#
# Extra image configuration defaults
#
# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
# images. Some of these options are added to certain image types automatically. The
# variable can contain the following options:
#  "dbg-pkgs"       - add -dbg packages for all installed packages
#                     (adds symbol information for debugging/profiling)
#  "src-pkgs"       - add -src packages for all installed packages
#                     (adds source code for debugging)
#  "dev-pkgs"       - add -dev packages for all installed packages
#                     (useful if you want to develop against libs in the image)
#  "ptest-pkgs"     - add -ptest packages for all ptest-enabled packages
#                     (useful if you want to run the package test suites)
#  "tools-sdk"      - add development tools (gcc, make, pkgconfig etc.)
#  "tools-debug"    - add debugging tools (gdb, strace)
#  "eclipse-debug"  - add Eclipse remote debugging support
#  "tools-profile"  - add profiling tools (oprofile, lttng, valgrind)
#  "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
#  "debug-tweaks"   - make an image suitable for development
#                     e.g. ssh root access has a blank password
# There are other application targets that can be used here too, see
# meta/classes-recipe/image.bbclass and
# meta/classes-recipe/core-image.bbclass for more details.
# We default to enabling the debugging tweaks.
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"

#add chromium to the image
IMAGE_INSTALL:append = " chromium-ozone-wayland ros-core"

#
# Additional image features
#
# The following is a list of additional classes to use when building images which
# enable extra features. Some available options which can be included in this variable
# are:
#   - 'buildstats' collect build statistics
USER_CLASSES ?= "buildstats "

#
# Runtime testing of images
#
# The build system can test booting virtual machine images under qemu (an emulator)
# after any root filesystems are created and run tests against those images. It can also
# run tests against any SDK that are built. To enable this uncomment these lines.
# See meta/classes-recipe/test{image,sdk}.bbclass for further details.
#IMAGE_CLASSES += "testimage testsdk"
#TESTIMAGE_AUTO:qemuall = "1"

#
# Interactive shell configuration
#
# Under certain circumstances the system may need input from you and to do this it
# can launch an interactive shell. It needs to do this since the build is
# multithreaded and needs to be able to handle the case where more than one parallel
# process may require the user's attention. The default is iterate over the available
# terminal types to find one that works.
#
# Examples of the occasions this may happen are when resolving patches which cannot
# be applied, to use the devshell or the kernel menuconfig
#
# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
# Note: currently, Konsole support only works for KDE 3.x due to the way
# newer Konsole versions behave
#OE_TERMINAL = "auto"
# By default disable interactive patch resolution (tasks will just fail instead):
PATCHRESOLVE = "noop"

#
# Disk Space Monitoring during the build
#
# Monitor the disk space during the build. If there is less that 1GB of space or less
# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
# shutdown the build. If there is less than 100MB or 1K inodes, perform a hard halt
# of the build. The reason for this is that running completely out of space can corrupt
# files and damages the build in ways which may not be easily recoverable.
# It's necessary to monitor /tmp, if there is no space left the build will fail
# with very exotic errors.
BB_DISKMON_DIRS ??= "\
    STOPTASKS,${TMPDIR},1G,100K \
    STOPTASKS,${DL_DIR},1G,100K \
    STOPTASKS,${SSTATE_DIR},1G,100K \
    STOPTASKS,/tmp,100M,100K \
    HALT,${TMPDIR},100M,1K \
    HALT,${DL_DIR},100M,1K \
    HALT,${SSTATE_DIR},100M,1K \
    HALT,/tmp,10M,1K"

#
# Shared-state files from other locations
#
# As mentioned above, shared state files are prebuilt cache data objects which can be
# used to accelerate build time. This variable can be used to configure the system
# to search other mirror locations for these objects before it builds the data itself.
#
# This can be a filesystem directory, or a remote url such as https or ftp. These
# would contain the sstate-cache results from previous builds (possibly from other
# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
# cache locations to check for the shared objects.
# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
# at the end as shown in the examples below. This will be substituted with the
# correct path within the directory structure.
#SSTATE_MIRRORS ?= "\
#file://.* https://someserver.tld/share/sstate/PATH;downloadfilename=PATH \
#file://.* file:///some/local/dir/sstate/PATH"

#
# Yocto Project SState Mirror
#
# The Yocto Project has prebuilt artefacts available for its releases, you can enable
# use of these by uncommenting some of the following lines. This will mean the build uses
# the network to check for artefacts at the start of builds, which does slow it down
# initially but it will then speed up the builds by not having to build things if they are
# present in the cache. It assumes you can download something faster than you can build it
# which will depend on your network.
# Note: For this to work you also need hash-equivalence passthrough to the matching server
# There is a choice between our sstate server directly and a faster content delivery network
# (CDN) kindly provided by JSDelivr, uncomment one of the SSTATE_MIRRORS lines, not both.
# Using the CDN rather than the yoctoproject.org address is suggested/preferred.
#
#BB_HASHSERVE_UPSTREAM = 'wss://hashserv.yoctoproject.org/ws'
#SSTATE_MIRRORS ?= "file://.* http://cdn.jsdelivr.net/yocto/sstate/all/PATH;downloadfilename=PATH"
#
###SSTATE_MIRRORS ?= "file://.* http://sstate.yoctoproject.org/all/PATH;downloadfilename=PATH"


#
# Qemu configuration
#
# By default native qemu will build with a builtin VNC server where graphical output can be
# seen. The line below enables the SDL UI frontend too.
PACKAGECONFIG:append:pn-qemu-system-native = " sdl"
# By default libsdl2-native will be built, if you want to use your host's libSDL instead of 
# the minimal libsdl built by libsdl2-native then uncomment the ASSUME_PROVIDED line below.
#ASSUME_PROVIDED += "libsdl2-native"

# You can also enable the Gtk UI frontend, which takes somewhat longer to build, but adds
# a handy set of menus for controlling the emulator.
#PACKAGECONFIG:append:pn-qemu-system-native = " gtk+"

#
# Hash Equivalence
#
# Enable support for automatically running a local hash equivalence server and
# instruct bitbake to use a hash equivalence aware signature generator. Hash
# equivalence improves reuse of sstate by detecting when a given sstate
# artifact can be reused as equivalent, even if the current task hash doesn't
# match the one that generated the artifact.
#
# A shared hash equivalent server can be set with "<HOSTNAME>:<PORT>" format
#
BB_HASHSERVE = "auto"
BB_SIGNATURE_HANDLER = "OEEquivHash"

#
# Memory Resident Bitbake
#
# Bitbake's server component can stay in memory after the UI for the current command
# has completed. This means subsequent commands can run faster since there is no need
# for bitbake to reload cache files and so on. Number is in seconds, after which the
# server will shut down.
#
#BB_SERVER_TIMEOUT = "60"

# CONF_VERSION is increased each time build/conf/ changes incompatibly and is used to

You are reporting this against 1.80 but the latest stable is 1.84. Can you reproduce this on the latest stable? Or nightly?

@orascheg Yocto seems to support many customizations of its list of targets that we do not. Please include the target spec definition that you are using for this build, if you are aware of one.

[saethlin]

I suspect this is just a duplicate of #127396, which is why I'm asking if this still crashes on stable.

[workingjubilee]

yeah, it looks like poky's latest rust is actually 1.81.0 which would have fixed this issue if you're correct.

[workingjubilee]

scarthgap is apparently poky 5.0.6 which does not include that rust version bump, so it's far out of support for us.

[orascheg]

Target is amd64 or x86_64 in Yocto speak. I will try to switch to 1.81.0 and test if it still crashing. If so, I will do a report at Yocto project with the request to update meta-lts-mixins

[orascheg]

scarthgap is apparently poky 5.0.6 which does not include that rust version bump, so it's far out of support for us.

Therefore, meta-lts-mixin is used (branch scarthgap/rust). This layer enables integration of newer component versions into the long term service (LTS) releases, which is currently at rust version 1.80.1. This was working fine until some component was making the rust panic showing up (with the pull from 29th January)
I have tried to port back version rust 1.81.0 from Yocto branch master. However, I experience problems with cargo ($WORKDIR is ńot properly set for it in Scarthgap). It seems that rust is a lot faster innovating than Yocto and the build environment in Yocto is not so trivial... I am still working on it.

[orascheg]

Now I have managed to get the back-port running. (it was the introduction of $UNPACKDIR in the newer Yocto variants). The bug is fixed in 1.81.0. Thank you all for your support.
