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

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

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

531 If your target CPU does not have a Floating Point Unit (FPU) or a

533 functions, then everything will need to be compiled with soft floating
534 point support (-msoft-float).
