277 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
279 config PKG_BUILD_PARALLEL
281 prompt "Compile certain packages parallelized"
284 This adds a -jX option to certain packages that are known to
285 behave well for parallel build.
287 Note that this may overcommit CPU resources depending on the
288 -j level of the main make process, the number of package
289 submake jobs selected below and the number of actual CPUs present.
290 Example: If the main make is passed a -j4 and the submake -j
291 is also set to 4, we may end up with 16 parallel make processes
294 You get maximum build performance, if you set the package build
295 jobs to the number of CPUs (cores) available and also start the main
296 make process with -jX, where X is the number of CPUs (cores).
297 However, make sure you have enough RAM available for
298 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
300 If you are unsure, select N.
302 config PKG_BUILD_JOBS

311 config PKG_DEFAULT_PARALLEL
313 prompt "Parallelize the default package build rule (May break build)"
314 depends on PKG_BUILD_PARALLEL
317 Always set the default package build rules to parallel build.
319 WARNING: This may break build or kill your cat, as it builds
320 packages with multiple jobs that are probably not tested in
321 a parallel build environment.
323 Only say Y, if you don't mind fixing broken packages.
324 Before reporting build bugs, set this to N and re-run the build.
326 config TOOLCHAIN_PARALLEL
328 prompt "Parallelize the toolchain build (May break build)"
329 depends on PKG_BUILD_PARALLEL
332 Build the toolchain with parallel make jobs.
333 This speeds up the toolchain build on SMP machines, but may
334 break the build for certain toolchain versions.
336 If you say Y, toolchain build might break.
337 Before reporting build bugs, set this to N and re-run the build.

378 config STRIP_KERNEL_EXPORTS
379 bool "Strip unnecessary exports from the kernel image"
381 Reduces kernel size by stripping unused kernel exports from the kernel image
382 Note that this might make the kernel incompatible with any kernel modules that
383 were not selected at the time the kernel image was created
386 bool "Strip unnecessary functions from libraries"
388 Reduces libraries to only those functions that are necessary for using all
389 selected packages (including those selected as <M>)
390 Note that this will make the system libraries incompatible with most of the packages
391 that are not selected during the build process

449 config KERNEL_GIT_LOCAL_REPOSITORY
450 string "Enter path to local reference repository" if DEVEL

454 In this instance, the --refererence option of git clone will
455 be used thus creating a quick local clone of your repo.

460 If enabled log files will be written to the ./log directory
462 config SRC_TREE_OVERRIDE
463 bool "Enable package source tree override" if DEVEL
465 If enabled, you can force a package to use a git tree as source
466 code instead of the normal tarball. Create a symlink 'git-src'
467 in the package directory, pointing to the .git tree that you want
468 to pull the source code from

484 If your target CPU does not have a Floating Point Unit (FPU) or a
485 kernel FPU emulator, but you still wish to support floating point
486 functions, then everything will need to be compiled with soft floating
487 point support (-msoft-float).
