148 this optional support will get disabled for this package.
152 bool "Compile with full language support"

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

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

404 config STRIP_KERNEL_EXPORTS
405 bool "Strip unnecessary exports from the kernel image"
407 Reduces kernel size by stripping unused kernel exports from the kernel image
408 Note that this might make the kernel incompatible with any kernel modules that
409 were not selected at the time the kernel image was created
412 bool "Strip unnecessary functions from libraries"
414 Reduces libraries to only those functions that are necessary for using all
415 selected packages (including those selected as <M>)
416 Note that this will make the system libraries incompatible with most of the packages
417 that are not selected during the build process
420 prompt "Preferred standard C++ library"
421 default USE_LIBSTDCXX if USE_EGLIBC
424 Select the preferred standard C++ library for all packages that support this.

490 config KERNEL_GIT_LOCAL_REPOSITORY
491 string "Enter path to local reference repository" if DEVEL
494 Enter a full pathname to a local reference git repository.
495 In this instance, the --refererence option of git clone will
496 be used thus creating a quick local clone of your repo.

504 bool "Enable package source tree override" if DEVEL
506 If enabled, you can force a package to use a git tree as source

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