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.

162 config COLLECT_KERNEL_DEBUG
164 prompt "Collect kernel debug information"
165 select KERNEL_DEBUG_INFO
168 This collects debugging symbols from the kernel and all compiled modules.
169 Useful for release builds, so that kernel issues can be debugged offline later.
171 comment "Kernel build options"
173 config KERNEL_DEBUG_FS
174 bool "Compile the kernel with Debug FileSystem enabled"
178 debugfs is a virtual file system that kernel developers use to put
179 debugging files into. Enable this option to be able to read and
180 write to these files.
182 config KERNEL_PROFILING
183 bool "Compile the kernel with profiling enabled"
186 Enable the extended profiling support mechanisms used by profilers such
189 config KERNEL_KALLSYMS
190 bool "Compile the kernel with symbol table information"
193 This will give you more information in stack traces from kernel oopses
195 config KERNEL_DEBUG_KERNEL
199 config KERNEL_DEBUG_INFO
200 bool "Compile the kernel with debug information"
202 select KERNEL_DEBUG_KERNEL
204 This will compile your kernel and modules with debug information.
206 comment "Package build options"
210 prompt "Compile packages with debugging info"
213 Adds -g3 to the CFLAGS
217 prompt "Enable IPv6 support in packages"

222 comment "Stripping options"
225 prompt "Binary stripping method"
226 default USE_STRIP if EXTERNAL_TOOLCHAIN
227 default USE_STRIP if USE_GLIBC || USE_EGLIBC
230 Select the binary stripping method you wish to use.
235 This will install unstripped binaries (useful for native compiling/debugging)
240 This will install binaries stripped using strip from binutils
249 This will install binaries stripped using sstrip
254 prompt "Strip arguments"
256 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
257 default "--strip-all"
259 Specifies arguments passed to the strip command when stripping binaries
261 config STRIP_KERNEL_EXPORTS
263 bool "Strip unnecessary exports from the kernel image"
265 Reduces kernel size by stripping unused kernel exports from the kernel image
266 Note that this might make the kernel incompatible with any kernel modules that
267 were not selected at the time the kernel image was created
270 bool "Strip unnecessary functions from libraries"
272 Reduces libraries to only those functions that are necessary for using all
273 selected packages (including those selected as <M>)
274 Note that this will make the system libraries incompatible with most of the packages
275 that are not selected during the build process
280 bool "Advanced configuration options (for developers)"

287 config DOWNLOAD_FOLDER
288 string "Download folder" if DEVEL
292 string "Local mirror for source packages" if DEVEL

302 string "Build suffix to append to the BUILD_DIR variable" if DEVEL
305 Build suffix to append to the BUILD_DIR variable, i.e: build_dir_suffix
307 config TARGET_ROOTFS_DIR
308 string "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
311 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with custom path.
312 Use this option to re-define the location of the target root file system directory.
315 bool "Use ccache" if DEVEL
318 Compiler cache; see http://ccache.samba.org/
320 config EXTERNAL_KERNEL_TREE
321 string "Use external kernel tree" if DEVEL
324 config KERNEL_GIT_CLONE_URI
325 string "Enter git repository to clone" if DEVEL
328 Enter the full git repository path i.e.:
329 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
330 This will create a git clone of the kernel in your build
333 config KERNEL_GIT_LOCAL_REPOSITORY
334 string "Enter path to local reference repository" if DEVEL
337 Enter a full pathname to a local reference git repository.
338 In this instance, the --refererence option of git clone will
339 be used thus creating a quick local clone of your repo.
341 menuconfig TARGET_OPTIONS
342 bool "Target Options" if DEVEL
344 config TARGET_OPTIMIZATION
345 string "Target Optimizations" if TARGET_OPTIONS
346 default DEFAULT_TARGET_OPTIMIZATION
348 Optimizations to use when building for the target host.
351 bool "Use software floating point by default" if TARGET_OPTIONS
353 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
355 If your target CPU does not have a Floating Point Unit (FPU) or a
356 kernel FPU emulator, but you still wish to support floating point
357 functions, then everything will need to be compiled with soft floating
358 point support (-msoft-float).
