8 bool "Advanced configuration options (for developers)"
12 bool "Show broken platforms / packages" 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/
72 config EXTERNAL_KERNEL_TREE
73 string "Use external kernel tree" if DEVEL
76 config KERNEL_GIT_CLONE_URI
77 string "Enter git repository to clone" if DEVEL
80 Enter the full git repository path i.e.:
81 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
82 This will create a git clone of the kernel in your build directory.
84 config KERNEL_GIT_LOCAL_REPOSITORY
85 string "Enter path to local reference repository" if DEVEL
86 depends on (KERNEL_GIT_CLONE_URI != "")
89 Enter a full pathname to a local reference git repository.
90 In this instance, the --reference option of git clone will
91 be used thus creating a quick local clone of your repo.
94 string "Enter git ref at which to checkout" if DEVEL
95 depends on (KERNEL_GIT_CLONE_URI != "")
98 Enter the git ref at which to checkout the git repository
99 after it is cloned, and before making it a tar-ball.
100 It can be a git hash or a branch name.
101 If unused, the clone's repository HEAD will be checked-out.
104 bool "Enable log files during build process" if DEVEL
106 If enabled, log files will be written to the ./log directory.
108 config SRC_TREE_OVERRIDE
109 bool "Enable package source tree override" if DEVEL
111 If enabled, you can force a package to use a git tree as source
112 code instead of the normal tarball. Create a symlink 'git-src'
113 in the package directory, pointing to the .git tree that you want
114 to pull the source code from.
116 config EXTRA_OPTIMIZATION
117 string "Additional compiler options" if DEVEL
118 default "-fno-caller-saves -fno-plt" if !CONFIG_EXTERNAL_TOOLCHAIN && !arc
119 default "-fno-caller-saves"
121 Extra target-independent optimizations to use when building for the target.
