2 # This file is your local configuration file and is where all local user settings
3 # are placed. The comments in this file give some guide to the options a new user
4 # to the system might want to change but pretty much any configuration option can
5 # be set in this file. More adventurous users can look at local.conf.extended
6 # which contains other examples of configuration which can be placed in this file
7 # but new users likely won't need any of them initially.
9 # Lines starting with the '#' character are commented out and in some cases the
10 # default values are provided as comments to show people example syntax. Enabling
11 # the option is a question of removing the # character and making any change to the
12 # variable as required.
17 # You need to select a specific machine to target the build with. There are a selection
18 # of emulated machines available which can boot and run in the QEMU emulator:
21 #MACHINE ?= "qemuarm64"
22 #MACHINE ?= "qemumips"
23 #MACHINE ?= "qemumips64"
26 #MACHINE ?= "qemux86-64"
28 # There are also the following hardware board target machines included for
29 # demonstration purposes:
31 #MACHINE ?= "beaglebone"
32 #MACHINE ?= "genericx86"
33 #MACHINE ?= "genericx86-64"
34 #MACHINE ?= "mpc8315e-rdb"
35 #MACHINE ?= "edgerouter"
37 # This sets the default machine to be qemux86 if no other machine is selected:
41 # Where to place downloads
43 # During a first build the system will download many different source code tarballs
44 # from various upstream projects. This can take a while, particularly if your network
45 # connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
46 # can preserve this directory to speed up this part of subsequent builds. This directory
47 # is safe to share between multiple builds on the same machine too.
49 # The default is a downloads directory under TOPDIR which is the build directory.
51 #DL_DIR ?= "${TOPDIR}/downloads"
54 # Where to place shared-state files
56 # BitBake has the capability to accelerate builds based on previously built output.
57 # This is done using "shared state" files which can be thought of as cache objects
58 # and this option determines where those files are placed.
60 # You can wipe out TMPDIR leaving this directory intact and the build would regenerate
61 # from these files if no changes were made to the configuration. If changes were made
62 # to the configuration, only shared state files where the state was still valid would
63 # be used (done using checksums).
65 # The default is a sstate-cache directory under TOPDIR.
67 #SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
70 # Where to place the build output
72 # This option specifies where the bulk of the building work should be done and
73 # where BitBake should place its temporary files and output. Keep in mind that
74 # this includes the extraction and compilation of many applications and the toolchain
75 # which can use Gigabytes of hard disk space.
77 # The default is a tmp directory under TOPDIR.
79 #TMPDIR = "${TOPDIR}/tmp"
82 # Default policy config
84 # The distribution setting controls which policy settings are used as defaults.
85 # The default value is fine for general Yocto project use, at least initially.
86 # Ultimately when creating custom policy, people will likely end up subclassing
90 # As an example of a subclass there is a "bleeding" edge policy configuration
91 # where many versions are set to the absolute latest code from the upstream
92 # source control systems. This is just mentioned here as an example, its not
93 # useful to most new users.
94 # DISTRO ?= "poky-bleeding"
97 # Package Management configuration
99 # This variable lists which packaging formats to enable. Multiple package backends
100 # can be enabled at once and the first item listed in the variable will be used
101 # to generate the root filesystems.
103 # - 'package_deb' for debian style deb files
104 # - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
105 # - 'package_rpm' for rpm style packages
106 # E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
108 PACKAGE_CLASSES ?= "package_rpm"
111 # SDK target architecture
113 # This variable specifies the architecture to build SDK items for and means
114 # you can build the SDK packages for architectures other than the machine you are
115 # running the build on (i.e. building i686 packages on an x86_64 host).
116 # Supported values are i686 and x86_64
117 #SDKMACHINE ?= "i686"
120 # Extra image configuration defaults
122 # The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
123 # images. Some of these options are added to certain image types automatically. The
124 # variable can contain the following options:
125 # "dbg-pkgs" - add -dbg packages for all installed packages
126 # (adds symbol information for debugging/profiling)
127 # "dev-pkgs" - add -dev packages for all installed packages
128 # (useful if you want to develop against libs in the image)
129 # "ptest-pkgs" - add -ptest packages for all ptest-enabled packages
130 # (useful if you want to run the package test suites)
131 # "tools-sdk" - add development tools (gcc, make, pkgconfig etc.)
132 # "tools-debug" - add debugging tools (gdb, strace)
133 # "eclipse-debug" - add Eclipse remote debugging support
134 # "tools-profile" - add profiling tools (oprofile, lttng, valgrind)
135 # "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
136 # "debug-tweaks" - make an image suitable for development
137 # e.g. ssh root access has a blank password
138 # There are other application targets that can be used here too, see
139 # meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.
140 # We default to enabling the debugging tweaks.
141 EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
144 # Additional image features
146 # The following is a list of additional classes to use when building images which
147 # enable extra features. Some available options which can be included in this variable
149 # - 'buildstats' collect build statistics
150 # - 'image-mklibs' to reduce shared library files size for an image
151 # - 'image-prelink' in order to prelink the filesystem image
152 # - 'image-swab' to perform host system intrusion detection
153 # NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
154 # NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended
155 USER_CLASSES ?= "buildstats image-mklibs image-prelink"
158 # Runtime testing of images
160 # The build system can test booting virtual machine images under qemu (an emulator)
161 # after any root filesystems are created and run tests against those images. To
162 # enable this uncomment this line. See classes/testimage(-auto).bbclass for
166 # Interactive shell configuration
168 # Under certain circumstances the system may need input from you and to do this it
169 # can launch an interactive shell. It needs to do this since the build is
170 # multithreaded and needs to be able to handle the case where more than one parallel
171 # process may require the user's attention. The default is iterate over the available
172 # terminal types to find one that works.
174 # Examples of the occasions this may happen are when resolving patches which cannot
175 # be applied, to use the devshell or the kernel menuconfig
177 # Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
178 # Note: currently, Konsole support only works for KDE 3.x due to the way
179 # newer Konsole versions behave
180 #OE_TERMINAL = "auto"
181 # By default disable interactive patch resolution (tasks will just fail instead):
182 PATCHRESOLVE = "noop"
185 # Disk Space Monitoring during the build
187 # Monitor the disk space during the build. If there is less that 1GB of space or less
188 # than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
189 # shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
190 # of the build. The reason for this is that running completely out of space can corrupt
191 # files and damages the build in ways which may not be easily recoverable.
192 # It's necesary to monitor /tmp, if there is no space left the build will fail
193 # with very exotic errors.

205 # Shared-state files from other locations
207 # As mentioned above, shared state files are prebuilt cache data objects which can
208 # used to accelerate build time. This variable can be used to configure the system
209 # to search other mirror locations for these objects before it builds the data itself.
211 # This can be a filesystem directory, or a remote url such as http or ftp. These
212 # would contain the sstate-cache results from previous builds (possibly from other
213 # machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
214 # cache locations to check for the shared objects.
215 # NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
216 # at the end as shown in the examples below. This will be substituted with the
217 # correct path within the directory structure.

226 # By default qemu will build with a builtin VNC server where graphical output can be
227 # seen. The two lines below enable the SDL backend too. By default libsdl-native will
