306 config PKG_BUILD_PARALLEL
308 prompt "Compile certain packages parallelized"
311 This adds a -jX option to certain packages that are known to
312 behave well for parallel build. By default the package make processes
313 use the main jobserver, in which case this option only takes effect
314 when you add -jX to the make command.
316 If you are unsure, select N.
318 config PKG_BUILD_USE_JOBSERVER
320 prompt "Use top-level make jobserver for packages"
321 depends on PKG_BUILD_PARALLEL
324 This passes the main make process jobserver fds to package builds,
325 enabling full parallelization across different packages
327 Note that disabling this may overcommit CPU resources depending on the
328 -j level of the main make process, the number of package
329 submake jobs selected below and the number of actual CPUs present.
330 Example: If the main make is passed a -j4 and the submake -j
331 is also set to 4, we may end up with 16 parallel make processes
335 config PKG_BUILD_JOBS
337 prompt "Number of package submake jobs (2-512)"

347 depends on PKG_BUILD_PARALLEL
351 Always set the default package build rules to parallel build.
353 WARNING: This may break build or kill your cat, as it builds
354 packages with multiple jobs that are probably not tested in
355 a parallel build environment.
357 Only say Y, if you don't mind fixing broken packages.
358 Before reporting build bugs, set this to N and re-run the build.
360 config TOOLCHAIN_PARALLEL
362 prompt "Parallelize the toolchain build (May break build)"
363 depends on PKG_BUILD_PARALLEL
367 Build the toolchain with parallel make jobs.
368 This speeds up the toolchain build on SMP machines, but may
369 break the build for certain toolchain versions.
371 If you say Y, toolchain build might break.
372 Before reporting build bugs, set this to N and re-run the build.

413 config STRIP_KERNEL_EXPORTS
414 bool "Strip unnecessary exports from the kernel image"
416 Reduces kernel size by stripping unused kernel exports from the kernel image
417 Note that this might make the kernel incompatible with any kernel modules that
418 were not selected at the time the kernel image was created
421 bool "Strip unnecessary functions from libraries"
423 Reduces libraries to only those functions that are necessary for using all
424 selected packages (including those selected as <M>)
425 Note that this will make the system libraries incompatible with most of the packages
426 that are not selected during the build process
429 prompt "Preferred standard C++ library"
430 default USE_LIBSTDCXX if USE_EGLIBC

499 config KERNEL_GIT_LOCAL_REPOSITORY
500 string "Enter path to local reference repository" if DEVEL

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

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