8 bool "Advanced configuration options (for developers)"
12 bool "Show broken platforms / packages / devices" if DEVEL
16 string "Binary folder" if DEVEL
19 Store built firmware images and filesystem images in this directory.
20 If not set, uses './bin/$(BOARD)'
22 config DOWNLOAD_FOLDER
23 string "Download folder" if DEVEL
26 Store downloaded source bundles in this directory.
27 If not set then defaults to './dl', which is removed by operations such as
28 'git clean -xdf' or 'make distclean'.
29 This option is useful if you have a low bandwidth Internet connection, and by
30 setting a path outside the OpenWrt tree downloads will be saved.
33 string "Local mirror for source packages" if DEVEL
37 bool "Automatic rebuild of packages" if DEVEL
40 Automatically rebuild packages when their files change.
43 bool "Automatic removal of build directories" if DEVEL
46 Automatically delete build directories after make target completed.
47 This allows you to symlink build_dir into a scratch location, e.g. a ramdisk,
48 which does not have enough space to keep a complete build_dir.
51 string "Build suffix to append to the target BUILD_DIR variable" if DEVEL
54 Build suffix to append to the BUILD_DIR variable, i.e: './build_dir/{target-build-dir}_$(BUILD_SUFFIX)'.
55 This allows you to switch to a different .config whilst retaining all the build
56 objects generated by the first .config
58 config TARGET_ROOTFS_DIR
59 string "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
62 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with
63 custom path. Use this option to re-define the location of the target
64 root filesystem directory.
67 bool "Use ccache" if DEVEL
70 Compiler cache; see https://ccache.samba.org/
73 string "Set ccache directory" if CCACHE
76 Store ccache in this directory.
77 If not set, uses './.ccache'
79 config EXTERNAL_KERNEL_TREE
80 string "Use external kernel tree" if DEVEL
83 config KERNEL_GIT_CLONE_URI
84 string "Enter git repository to clone" if DEVEL
87 Enter the full git repository path i.e.:
88 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
89 This will create a git clone of the kernel in your build directory.
91 config KERNEL_GIT_LOCAL_REPOSITORY
92 string "Enter path to local reference repository" if DEVEL
93 depends on (KERNEL_GIT_CLONE_URI != "")
96 Enter a full pathname to a local reference git repository.
97 In this instance, the --reference option of git clone will
98 be used thus creating a quick local clone of your repo.
100 config KERNEL_GIT_REF
101 string "Enter git ref at which to checkout" if DEVEL
102 depends on (KERNEL_GIT_CLONE_URI != "")
105 Enter the git ref at which to checkout the git repository
106 after it is cloned, and before making it a tar-ball.
107 It can be a git hash or a branch name.
108 If unused, the clone's repository HEAD will be checked-out.
111 bool "Enable log files during build process" if DEVEL
113 If enabled, log files will be written to the ./log directory.
116 string "Log folder" if DEVEL
119 Store build logs in this directory.
120 If not set, uses './logs'
122 config SRC_TREE_OVERRIDE
123 bool "Enable package source tree override" if DEVEL
125 If enabled, you can force a package to use a git tree as source
126 code instead of the normal tarball. Create a symlink 'git-src'
127 in the package directory, pointing to the .git tree that you want
128 to pull the source code from.
130 config EXTRA_OPTIMIZATION
131 string "Additional compiler options" if DEVEL
132 default "-fno-caller-saves -fno-plt" if !CONFIG_EXTERNAL_TOOLCHAIN && !arc
133 default "-fno-caller-saves"
135 Extra target-independent optimizations to use when building for the target.
