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

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

384 bool "Strip unnecessary exports from the kernel image"
386 Reduces kernel size by stripping unused kernel exports from the kernel image
387 Note that this might make the kernel incompatible with any kernel modules that
388 were not selected at the time the kernel image was created
391 bool "Strip unnecessary functions from libraries"
393 Reduces libraries to only those functions that are necessary for using all
394 selected packages (including those selected as <M>)
395 Note that this will make the system libraries incompatible with most of the packages
396 that are not selected during the build process
399 prompt "Preferred standard C++ library"
400 default USE_LIBSTDCXX if USE_EGLIBC
403 Select the preferred standard C++ library for all packages that support this.

469 config KERNEL_GIT_LOCAL_REPOSITORY
470 string "Enter path to local reference repository" if DEVEL
473 Enter a full pathname to a local reference git repository.
474 In this instance, the --refererence option of git clone will
475 be used thus creating a quick local clone of your repo.

480 If enabled log files will be written to the ./log directory
482 config SRC_TREE_OVERRIDE
483 bool "Enable package source tree override" if DEVEL
485 If enabled, you can force a package to use a git tree as source

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