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

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

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

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