129 config DISPLAY_SUPPORT
130 bool "Show packages that require graphics support (local or remote)"
133 config BUILD_PATENTED
135 bool "Compile with support for patented functionality"
137 When this option is disabled, software which provides patented functionality will not be built.
138 In case software provides optional support for patented functionality,
139 this optional support will get disabled for this package.
143 bool "Compile with full language support"
145 When this option is enabled, packages are built with the full versions of iconv and GNU gettext
146 instead of the default OpenWrt stubs.
150 prompt "Enable large file (files > 2 GB) support"
153 Enable large file (files > 2 GB) support.
155 config SHADOW_PASSWORDS
157 prompt "Enable shadow password support"

164 prompt "Remove ipkg/opkg status data files in final images"
167 This removes all ipkg/opkg status data files from the target directory before building the root fs
169 config COLLECT_KERNEL_DEBUG
171 prompt "Collect kernel debug information"
172 select KERNEL_DEBUG_INFO
175 This collects debugging symbols from the kernel and all compiled modules.
176 Useful for release builds, so that kernel issues can be debugged offline later.
178 comment "Kernel build options"
180 config KERNEL_DEBUG_FS
181 bool "Compile the kernel with Debug FileSystem enabled"
185 debugfs is a virtual file system that kernel developers use to put
186 debugging files into. Enable this option to be able to read and
187 write to these files.
189 config KERNEL_PROFILING
190 bool "Compile the kernel with profiling enabled"
193 Enable the extended profiling support mechanisms used by profilers such
196 config KERNEL_KALLSYMS
197 bool "Compile the kernel with symbol table information"
200 This will give you more information in stack traces from kernel oopses
202 config KERNEL_DEBUG_KERNEL
206 config KERNEL_DEBUG_INFO
207 bool "Compile the kernel with debug information"
209 select KERNEL_DEBUG_KERNEL
211 This will compile your kernel and modules with debug information.
213 comment "Package build options"
217 prompt "Compile packages with debugging info"
220 Adds -g3 to the CFLAGS
224 prompt "Enable IPv6 support in packages"
227 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
229 comment "Stripping options"
232 prompt "Binary stripping method"
233 default USE_STRIP if EXTERNAL_TOOLCHAIN
234 default USE_STRIP if USE_GLIBC || USE_EGLIBC
237 Select the binary stripping method you wish to use.
242 This will install unstripped binaries (useful for native compiling/debugging)
247 This will install binaries stripped using strip from binutils
256 This will install binaries stripped using sstrip
261 prompt "Strip arguments"
263 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
264 default "--strip-all"
266 Specifies arguments passed to the strip command when stripping binaries
268 config STRIP_KERNEL_EXPORTS
270 bool "Strip unnecessary exports from the kernel image"
272 Reduces kernel size by stripping unused kernel exports from the kernel image
273 Note that this might make the kernel incompatible with any kernel modules that
274 were not selected at the time the kernel image was created
277 bool "Strip unnecessary functions from libraries"
280 Reduces libraries to only those functions that are necessary for using all
281 selected packages (including those selected as <M>)
282 Note that this will make the system libraries incompatible with most of the packages
283 that are not selected during the build process
288 bool "Advanced configuration options (for developers)"
292 bool "Show broken platforms / packages" if DEVEL
295 config DOWNLOAD_FOLDER
296 string "Download folder" if DEVEL
300 string "Local mirror for source packages" if DEVEL

307 Automatically rebuild packages when their files change
310 string "Build suffix to append to the BUILD_DIR variable" if DEVEL
313 Build suffix to append to the BUILD_DIR variable, i.e: build_dir_suffix
315 config TARGET_ROOTFS_DIR
316 string "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
319 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with custom path.
320 Use this option to re-define the location of the target root file system directory.
323 bool "Use ccache" if DEVEL
326 Compiler cache; see http://ccache.samba.org/
328 config EXTERNAL_KERNEL_TREE
329 string "Use external kernel tree" if DEVEL
332 config KERNEL_GIT_CLONE_URI
333 string "Enter git repository to clone" if DEVEL
336 Enter the full git repository path i.e.:
337 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
338 This will create a git clone of the kernel in your build
341 config KERNEL_GIT_LOCAL_REPOSITORY
342 string "Enter path to local reference repository" if DEVEL
345 Enter a full pathname to a local reference git repository.
346 In this instance, the --refererence option of git clone will
347 be used thus creating a quick local clone of your repo.
349 menuconfig TARGET_OPTIONS
350 bool "Target Options" if DEVEL
352 config TARGET_OPTIMIZATION
353 string "Target Optimizations" if TARGET_OPTIONS
354 default DEFAULT_TARGET_OPTIMIZATION
356 Optimizations to use when building for the target host.
359 bool "Use software floating point by default" if TARGET_OPTIONS
361 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
363 If your target CPU does not have a Floating Point Unit (FPU) or a
364 kernel FPU emulator, but you still wish to support floating point
365 functions, then everything will need to be compiled with soft floating
366 point support (-msoft-float).
