poky/meta-poky/conf/local.conf.sample - mdmillerii/openbmc - Gitiles

 #
 # 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.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.
 #
 # 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 ?= "genericx86"
 #MACHINE ?= "genericx86-64"
 #MACHINE ?= "mpc8315e-rdb"
 #MACHINE ?= "edgerouter"
 #
 # This sets the default machine to be qemux86 if no other machine is selected:
 MACHINE ??= "qemux86"

 #
 # 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"
 # We default to rpm:
 PACKAGE_CLASSES ?= "package_rpm"

 #
 # 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 and x86_64
 #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)
 #  "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/image.bbclass and meta/classes/core-image.bbclass for more details.
 # We default to enabling the debugging tweaks.
 EXTRA_IMAGE_FEATURES ?= "debug-tweaks"

 #
 # 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
 #   - 'image-mklibs' to reduce shared library files size for an image
 #   - 'image-prelink' in order to prelink the filesystem image
 # NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
 # NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended
 USER_CLASSES ?= "buildstats image-mklibs image-prelink"

 #
 # 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 classes/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 that 100MB or 1K inodes, perform a hard abort
 # 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 necesary to monitor /tmp, if there is no space left the build will fail
 # with very exotic errors.

 # Shared-state files from other locations
 #
 # As mentioned above, shared state files are prebuilt cache data objects which can
 # 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 http 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.

 # present in the cache. It assumes you can download something faster than you can build it
 # which will depend on your network.
 #
 #SSTATE_MIRRORS ?= "file://.* http://sstate.yoctoproject.org/2.5/PATH;downloadfilename=PATH"
