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

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

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

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