257 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
259 config PKG_BUILD_PARALLEL
261 prompt "Compile certain packages parallelized"
264 This adds a -jX option to certain packages that are known to
265 behave well for parallel build.
267 Note that this may overcommit CPU resources depending on the
268 -j level of the main make process, the number of package
269 submake jobs selected below and the number of actual CPUs present.
270 Example: If the main make is passed a -j4 and the submake -j
271 is also set to 4, we may end up with 16 parallel make processes
274 You get maximum build performance, if you set the package build
275 jobs to the number of CPUs (cores) available and also start the main
276 make process with -jX, where X is the number of CPUs (cores).
277 However, make sure you have enough RAM available for
278 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
280 If you are unsure, select N.
282 config PKG_BUILD_JOBS
284 prompt "Number of package submake jobs (2-512)"
287 depends on PKG_BUILD_PARALLEL
289 The number of jobs (-jX) to pass to packages submake.
291 config PKG_DEFAULT_PARALLEL
293 prompt "Parallelize the default package build rule (May break build)"
294 depends on PKG_BUILD_PARALLEL
297 Always set the default package build rules to parallel build.
299 WARNING: This may break build or kill your cat, as it builds
300 packages with multiple jobs that are probably not tested in
301 a parallel build environment.
303 Only say Y, if you don't mind fixing broken packages.
304 Before reporting build bugs, set this to N and re-run the build.
306 config TOOLCHAIN_PARALLEL
308 prompt "Parallelize the toolchain build (May break build)"
309 depends on PKG_BUILD_PARALLEL
312 Build the toolchain with parallel make jobs.
313 This speeds up the toolchain build on SMP machines, but may
314 break the build for certain toolchain versions.
316 If you say Y, toolchain build might break.
317 Before reporting build bugs, set this to N and re-run the build.
319 comment "Stripping options"

323 default USE_STRIP if EXTERNAL_TOOLCHAIN
324 default USE_STRIP if USE_GLIBC || USE_EGLIBC
327 Select the binary stripping method you wish to use.
332 This will install unstripped binaries (useful for native compiling/debugging)
337 This will install binaries stripped using strip from binutils
346 This will install binaries stripped using sstrip
351 prompt "Strip arguments"
353 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
354 default "--strip-all"
356 Specifies arguments passed to the strip command when stripping binaries
358 config STRIP_KERNEL_EXPORTS
359 bool "Strip unnecessary exports from the kernel image"
361 Reduces kernel size by stripping unused kernel exports from the kernel image
362 Note that this might make the kernel incompatible with any kernel modules that
363 were not selected at the time the kernel image was created
366 bool "Strip unnecessary functions from libraries"
368 Reduces libraries to only those functions that are necessary for using all
369 selected packages (including those selected as <M>)
370 Note that this will make the system libraries incompatible with most of the packages
371 that are not selected during the build process

424 Enter the full git repository path i.e.:
425 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
426 This will create a git clone of the kernel in your build
429 config KERNEL_GIT_LOCAL_REPOSITORY
430 string "Enter path to local reference repository" if DEVEL
433 Enter a full pathname to a local reference git repository.
434 In this instance, the --refererence option of git clone will
435 be used thus creating a quick local clone of your repo.
438 bool "Enable log files during build process" if DEVEL
440 If enabled log files will be written to the ./log directory
442 config SRC_TREE_OVERRIDE
443 bool "Enable package source tree override" if DEVEL
445 If enabled, you can force a package to use a git tree as source
446 code instead of the normal tarball. Create a symlink 'git-src'
447 in the package directory, pointing to the .git tree that you want
448 to pull the source code from

462 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
464 If your target CPU does not have a Floating Point Unit (FPU) or a
465 kernel FPU emulator, but you still wish to support floating point
466 functions, then everything will need to be compiled with soft floating
467 point support (-msoft-float).
