146 In case software provides optional support for patented functionality,
147 this optional support will get disabled for this package.
151 bool "Compile with full language support"
153 When this option is enabled, packages are built with the full versions of iconv and GNU gettext
154 instead of the default OpenWrt stubs. If uClibc is used, it is also built with locale support.
156 config BUILD_STATIC_TOOLS

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

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

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

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

500 If enabled log files will be written to the ./log directory

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

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