# 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"

#MACHINE ?= "genericx86"

#MACHINE ?= "genericx86-64"

#MACHINE ?= "mpc8315e-rdb"

#MACHINE ?= "edgerouter"

MACHINE ?= "mitysom-5csx"

#

# 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

#   - 'image-swab' to perform host system intrusion detection

# 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

# image-prelink disabled for now due to issues with IFUNC symbol relocation

USER_CLASSES ?= "buildstats image-mklibs"

#

# 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. To

# enable this uncomment this line. See classes/testimage(-auto).bbclass for

# further details.

#TEST_IMAGE = "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.

#SSTATE_MIRRORS ?= "\

#file://.* http://someserver.tld/share/sstate/PATH;downloadfilename=PATH \n \

#file://.* file:///some/local/dir/sstate/PATH"

#

# Qemu configuration

#

# By default qemu will build with a builtin VNC server where graphical output can be

# seen. The two lines below enable the SDL backend too. By default libsdl-native will

# be built, if you want to use your host's libSDL instead of the minimal libsdl built

# by libsdl-native then uncomment the ASSUME_PROVIDED line below.

PACKAGECONFIG_append_pn-qemu-native = " sdl"

PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"

#ASSUME_PROVIDED += "libsdl-native"

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

# track the version of this file when it was generated. This can safely be ignored if

# this doesn't mean anything to you.
