291 config PKG_BUILD_PARALLEL
293 prompt "Compile certain packages parallelized"
296 This adds a -jX option to certain packages that are known to
297 behave well for parallel build.
299 Note that this may overcommit CPU resources depending on the
300 -j level of the main make process, the number of package
301 submake jobs selected below and the number of actual CPUs present.
302 Example: If the main make is passed a -j4 and the submake -j
303 is also set to 4, we may end up with 16 parallel make processes
306 You get maximum build performance, if you set the package build
307 jobs to the number of CPUs (cores) available and also start the main
308 make process with -jX, where X is the number of CPUs (cores).
309 However, make sure you have enough RAM available for
310 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
312 If you are unsure, select N.

332 config PKG_DEFAULT_PARALLEL
334 prompt "Parallelize the default package build rule (May break build)"
335 depends on PKG_BUILD_PARALLEL
339 Always set the default package build rules to parallel build.
341 WARNING: This may break build or kill your cat, as it builds
342 packages with multiple jobs that are probably not tested in
343 a parallel build environment.
345 Only say Y, if you don't mind fixing broken packages.
346 Before reporting build bugs, set this to N and re-run the build.
348 config TOOLCHAIN_PARALLEL
350 prompt "Parallelize the toolchain build (May break build)"
351 depends on PKG_BUILD_PARALLEL
355 Build the toolchain with parallel make jobs.
356 This speeds up the toolchain build on SMP machines, but may
357 break the build for certain toolchain versions.
359 If you say Y, toolchain build might break.
360 Before reporting build bugs, set this to N and re-run the build.

401 config STRIP_KERNEL_EXPORTS
402 bool "Strip unnecessary exports from the kernel image"
404 Reduces kernel size by stripping unused kernel exports from the kernel image
405 Note that this might make the kernel incompatible with any kernel modules that
406 were not selected at the time the kernel image was created
409 bool "Strip unnecessary functions from libraries"
411 Reduces libraries to only those functions that are necessary for using all
412 selected packages (including those selected as <M>)
413 Note that this will make the system libraries incompatible with most of the packages
414 that are not selected during the build process
417 prompt "Preferred standard C++ library"

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