219 comment "Package build options"
223 prompt "Compile packages with debugging info"
226 Adds -g3 to the CFLAGS
230 prompt "Enable IPv6 support in packages"
233 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
235 config PKG_BUILD_PARALLEL
237 prompt "Compile certain packages parallelized"
240 This adds a -jX option to certain packages that are known to
241 behave well for parallel build.
243 Note that this may overcommit CPU resources depending on the
244 -j level of the main make process, the number of package
245 submake jobs selected below and the number of actual CPUs present.
246 Example: If the main make is passed a -j4 and the submake -j
247 is also set to 4, we may end up with 16 parallel make processes
250 You get maximum build performance, if you set the package build
251 jobs to the number of CPUs (cores) available and also start the main
252 make process with -jX, where X is the number of CPUs (cores).
253 However, make sure you have enough RAM available for
254 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
256 If you are unsure, select N.
258 config PKG_BUILD_JOBS
260 prompt "Number of package submake jobs (2-512)"
263 depends on PKG_BUILD_PARALLEL
265 The number of jobs (-jX) to pass to packages submake.
267 config PKG_DEFAULT_PARALLEL
269 prompt "Parallelize the default package build rule (May break build)"
270 depends on PKG_BUILD_PARALLEL
273 Always set the default package build rules to parallel build.
275 WARNING: This may break build or kill your cat, as it builds
276 packages with multiple jobs that are probably not tested in
277 a parallel build environment.
279 Only say Y, if you don't mind fixing broken packages.
280 Before reporting build bugs, set this to N and re-run the build.
282 config TOOLCHAIN_PARALLEL
284 prompt "Parallelize the toolchain build (May break build)"
285 depends on PKG_BUILD_PARALLEL
288 Build the toolchain with parallel make jobs.
289 This speeds up the toolchain build on SMP machines, but may
290 break the build for certain toolchain versions.
292 If you say Y, toolchain build might break.
293 Before reporting build bugs, set this to N and re-run the build.
295 comment "Stripping options"

303 Select the binary stripping method you wish to use.
308 This will install unstripped binaries (useful for native compiling/debugging)
313 This will install binaries stripped using strip from binutils
322 This will install binaries stripped using sstrip
327 prompt "Strip arguments"
329 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
330 default "--strip-all"
332 Specifies arguments passed to the strip command when stripping binaries
334 config STRIP_KERNEL_EXPORTS
335 bool "Strip unnecessary exports from the kernel image"
337 Reduces kernel size by stripping unused kernel exports from the kernel image
338 Note that this might make the kernel incompatible with any kernel modules that
339 were not selected at the time the kernel image was created
342 bool "Strip unnecessary functions from libraries"
344 Reduces libraries to only those functions that are necessary for using all
345 selected packages (including those selected as <M>)
346 Note that this will make the system libraries incompatible with most of the packages
347 that are not selected during the build process

402 This will create a git clone of the kernel in your build
405 config KERNEL_GIT_LOCAL_REPOSITORY
406 string "Enter path to local reference repository" if DEVEL
409 Enter a full pathname to a local reference git repository.
410 In this instance, the --refererence option of git clone will
411 be used thus creating a quick local clone of your repo.
413 menuconfig TARGET_OPTIONS
414 bool "Target Options" if DEVEL
416 config TARGET_OPTIMIZATION

420 Optimizations to use when building for the target host.
423 bool "Use software floating point by default" if TARGET_OPTIONS
425 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
427 If your target CPU does not have a Floating Point Unit (FPU) or a
428 kernel FPU emulator, but you still wish to support floating point
429 functions, then everything will need to be compiled with soft floating
430 point support (-msoft-float).
432 Most people will answer N.
