148 this optional support will get disabled for this package.
152 bool "Compile with full language support"
154 When this option is enabled, packages are built with the full versions of iconv and GNU gettext

268 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
270 config PKG_BUILD_PARALLEL
272 prompt "Compile certain packages parallelized"
275 This adds a -jX option to certain packages that are known to
276 behave well for parallel build.
278 Note that this may overcommit CPU resources depending on the
279 -j level of the main make process, the number of package
280 submake jobs selected below and the number of actual CPUs present.
281 Example: If the main make is passed a -j4 and the submake -j
282 is also set to 4, we may end up with 16 parallel make processes
285 You get maximum build performance, if you set the package build
286 jobs to the number of CPUs (cores) available and also start the main
287 make process with -jX, where X is the number of CPUs (cores).
288 However, make sure you have enough RAM available for
289 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
291 If you are unsure, select N.
293 config PKG_BUILD_JOBS
295 prompt "Number of package submake jobs (2-512)"

304 prompt "Parallelize the default package build rule (May break build)"
305 depends on PKG_BUILD_PARALLEL
308 Always set the default package build rules to parallel build.
310 WARNING: This may break build or kill your cat, as it builds
311 packages with multiple jobs that are probably not tested in
312 a parallel build environment.
314 Only say Y, if you don't mind fixing broken packages.
315 Before reporting build bugs, set this to N and re-run the build.
317 config TOOLCHAIN_PARALLEL
319 prompt "Parallelize the toolchain build (May break build)"
320 depends on PKG_BUILD_PARALLEL
323 Build the toolchain with parallel make jobs.
324 This speeds up the toolchain build on SMP machines, but may
325 break the build for certain toolchain versions.
327 If you say Y, toolchain build might break.
328 Before reporting build bugs, set this to N and re-run the build.

369 config STRIP_KERNEL_EXPORTS
370 bool "Strip unnecessary exports from the kernel image"
372 Reduces kernel size by stripping unused kernel exports from the kernel image
373 Note that this might make the kernel incompatible with any kernel modules that
374 were not selected at the time the kernel image was created
377 bool "Strip unnecessary functions from libraries"
379 Reduces libraries to only those functions that are necessary for using all
380 selected packages (including those selected as <M>)
381 Note that this will make the system libraries incompatible with most of the packages
382 that are not selected during the build process

435 Enter the full git repository path i.e.:

437 This will create a git clone of the kernel in your build
440 config KERNEL_GIT_LOCAL_REPOSITORY
441 string "Enter path to local reference repository" if DEVEL
444 Enter a full pathname to a local reference git repository.
445 In this instance, the --refererence option of git clone will
446 be used thus creating a quick local clone of your repo.
449 bool "Enable log files during build process" if DEVEL
451 If enabled log files will be written to the ./log directory
453 config SRC_TREE_OVERRIDE
454 bool "Enable package source tree override" if DEVEL
456 If enabled, you can force a package to use a git tree as source
457 code instead of the normal tarball. Create a symlink 'git-src'
458 in the package directory, pointing to the .git tree that you want
459 to pull the source code from

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