444 config PKG_BUILD_PARALLEL
446 prompt "Compile certain packages parallelized"
449 This adds a -jX option to certain packages that are known to
450 behave well for parallel build. By default the package make processes
451 use the main jobserver, in which case this option only takes effect
452 when you add -jX to the make command.
454 If you are unsure, select N.

459 depends on PKG_BUILD_PARALLEL
462 This passes the main make process jobserver fds to package builds,
463 enabling full parallelization across different packages
465 Note that disabling this may overcommit CPU resources depending on the
466 -j level of the main make process, the number of package
467 submake jobs selected below and the number of actual CPUs present.
468 Example: If the main make is passed a -j4 and the submake -j
469 is also set to 4, we may end up with 16 parallel make processes
473 config PKG_BUILD_JOBS

485 depends on PKG_BUILD_PARALLEL
489 Always set the default package build rules to parallel build.
491 WARNING: This may break build or kill your cat, as it builds
492 packages with multiple jobs that are probably not tested in
493 a parallel build environment.
495 Only say Y, if you don't mind fixing broken packages.
496 Before reporting build bugs, set this to N and re-run the build.

541 Note that this might make the kernel incompatible with any kernel modules that
542 were not selected at the time the kernel image was created
545 bool "Strip unnecessary functions from libraries"
547 Reduces libraries to only those functions that are necessary for using all
548 selected packages (including those selected as <M>)
549 Note that this will make the system libraries incompatible with most of the packages
550 that are not selected during the build process
