6 bool "Advanced configuration options (for developers)"
10 bool "Show broken platforms / packages / devices" if DEVEL
14 string "Binary folder" if DEVEL
17 Store built firmware images and filesystem images in this directory.
18 If not set, uses './bin/$(BOARD)'
20 config DOWNLOAD_FOLDER
21 string "Download folder" if DEVEL
24 Store downloaded source bundles in this directory.
25 If not set then defaults to './dl', which is removed by operations such as
26 'git clean -xdf' or 'make distclean'.
27 This option is useful if you have a low bandwidth Internet connection, and by
28 setting a path outside the OpenWrt tree downloads will be saved.
31 string "Local mirror for source packages" if DEVEL
35 bool "Automatic rebuild of packages" if DEVEL
38 Automatically rebuild packages when their files change.
41 bool "Automatic removal of build directories" if DEVEL
44 Automatically delete build directories after make target completed.
45 This allows you to symlink build_dir into a scratch location, e.g. a ramdisk,
46 which does not have enough space to keep a complete build_dir.
49 string "Build suffix to append to the target BUILD_DIR variable" if DEVEL
52 Build suffix to append to the BUILD_DIR variable, i.e: './build_dir/{target-build-dir}_$(BUILD_SUFFIX)'.
53 This allows you to switch to a different .config whilst retaining all the build
54 objects generated by the first .config
56 config TARGET_ROOTFS_DIR
57 string "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
60 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with
61 custom path. Use this option to re-define the location of the target
62 root filesystem directory.
65 bool "Use ccache" if DEVEL
68 Compiler cache; see https://ccache.samba.org/
71 string "Set ccache directory" if CCACHE
74 Store ccache in this directory.
75 If not set, uses './.ccache'
78 string "Kernel extra CFLAGS" if DEVEL
81 config EXTERNAL_KERNEL_TREE
82 string "Use external kernel tree" if DEVEL
85 config KERNEL_GIT_CLONE_URI
86 string "Enter git repository to clone" if DEVEL
89 Enter the full git repository path i.e.:
90 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
91 This will create a git clone of the kernel in your build directory.
93 config KERNEL_GIT_LOCAL_REPOSITORY
94 string "Enter path to local reference repository" if DEVEL
95 depends on (KERNEL_GIT_CLONE_URI != "")
98 Enter a full pathname to a local reference git repository.
99 In this instance, the --reference option of git clone will
100 be used thus creating a quick local clone of your repo.
102 config KERNEL_GIT_REF
103 string "Enter git ref at which to checkout" if DEVEL
104 depends on (KERNEL_GIT_CLONE_URI != "")
107 Enter the git ref at which to checkout the git repository
108 after it is cloned, and before making it a tar-ball.
109 It can be a git hash or a branch name.
110 If unused, the clone's repository HEAD will be checked-out.
112 config KERNEL_GIT_MIRROR_HASH
113 string "Enter hash of Git kernel tree source checkout tarball" if DEVEL
114 depends on (KERNEL_GIT_CLONE_URI != "")
118 bool "Enable log files during build process" if DEVEL
120 If enabled, log files will be written to the ./log directory.
123 string "Log folder" if DEVEL
126 Store build logs in this directory.
127 If not set, uses './logs'
129 config SRC_TREE_OVERRIDE
130 bool "Enable package source tree override" if DEVEL
132 If enabled, you can force a package to use a git tree as source
133 code instead of the normal tarball. Create a symlink 'git-src'
134 in the package directory, pointing to the .git tree that you want
135 to pull the source code from.
137 config EXTRA_OPTIMIZATION
138 string "Additional compiler options" if DEVEL
139 default "-fno-caller-saves -fno-plt" if !CONFIG_EXTERNAL_TOOLCHAIN && !arc
140 default "-fno-caller-saves"
142 Extra target-independent optimizations to use when building for the target.
