167 comment "Kernel build options"
169 config KERNEL_DEBUG_FS
170 bool "Compile the kernel with Debug FileSystem enabled"
174 debugfs is a virtual file system that kernel developers use to put

176 write to these files.

202 comment "Package build options"
206 prompt "Compile packages with debugging info"
209 Adds -g3 to the CFLAGS
213 prompt "Enable IPv6 support in packages"
216 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
218 config PKG_BUILD_PARALLEL
220 prompt "Compile certain packages parallelized"
223 This adds a -jX option to certain packages that are known to
224 behave well for parallel build.
226 Note that this may overcommit CPU resources depending on the
227 -j level of the main make process, the number of package
228 submake jobs selected below and the number of actual CPUs present.
229 Example: If the main make is passed a -j4 and the submake -j
230 is also set to 4, we may end up with 16 parallel make processes
233 You get maximum build performance, if you set the package build
234 jobs to the number of CPUs (cores) available and also start the main
235 make process with -jX, where X is the number of CPUs (cores).
236 However, make sure you have enough RAM available for
237 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
239 If you are unsure, select N.
241 config PKG_BUILD_JOBS
243 prompt "Number of package submake jobs (2-512)"
246 depends on PKG_BUILD_PARALLEL
248 The number of jobs (-jX) to pass to packages submake.
250 comment "Stripping options"
253 prompt "Binary stripping method"
254 default USE_STRIP if EXTERNAL_TOOLCHAIN
255 default USE_STRIP if USE_GLIBC || USE_EGLIBC
258 Select the binary stripping method you wish to use.
263 This will install unstripped binaries (useful for native compiling/debugging)
268 This will install binaries stripped using strip from binutils
277 This will install binaries stripped using sstrip
282 prompt "Strip arguments"
284 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
285 default "--strip-all"
287 Specifies arguments passed to the strip command when stripping binaries
289 config STRIP_KERNEL_EXPORTS
291 bool "Strip unnecessary exports from the kernel image"
293 Reduces kernel size by stripping unused kernel exports from the kernel image
294 Note that this might make the kernel incompatible with any kernel modules that
295 were not selected at the time the kernel image was created
298 bool "Strip unnecessary functions from libraries"
300 Reduces libraries to only those functions that are necessary for using all
301 selected packages (including those selected as <M>)
302 Note that this will make the system libraries incompatible with most of the packages
303 that are not selected during the build process

335 config TARGET_ROOTFS_DIR
336 string "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
339 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with custom path.
340 Use this option to re-define the location of the target root file system directory.
343 bool "Use ccache" if DEVEL
346 Compiler cache; see http://ccache.samba.org/
348 config EXTERNAL_KERNEL_TREE
349 string "Use external kernel tree" if DEVEL

356 Enter the full git repository path i.e.:
357 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
358 This will create a git clone of the kernel in your build
361 config KERNEL_GIT_LOCAL_REPOSITORY
362 string "Enter path to local reference repository" if DEVEL
365 Enter a full pathname to a local reference git repository.
366 In this instance, the --refererence option of git clone will
367 be used thus creating a quick local clone of your repo.
369 menuconfig TARGET_OPTIONS
370 bool "Target Options" if DEVEL
372 config TARGET_OPTIMIZATION
373 string "Target Optimizations" if TARGET_OPTIONS
374 default DEFAULT_TARGET_OPTIMIZATION
376 Optimizations to use when building for the target host.
379 bool "Use software floating point by default" if TARGET_OPTIONS
381 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
383 If your target CPU does not have a Floating Point Unit (FPU) or a
384 kernel FPU emulator, but you still wish to support floating point
385 functions, then everything will need to be compiled with soft floating
386 point support (-msoft-float).
388 Most people will answer N.
