283 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
285 config PKG_BUILD_PARALLEL
287 prompt "Compile certain packages parallelized"
290 This adds a -jX option to certain packages that are known to
291 behave well for parallel build.
293 Note that this may overcommit CPU resources depending on the
294 -j level of the main make process, the number of package
295 submake jobs selected below and the number of actual CPUs present.
296 Example: If the main make is passed a -j4 and the submake -j
297 is also set to 4, we may end up with 16 parallel make processes
300 You get maximum build performance, if you set the package build
301 jobs to the number of CPUs (cores) available and also start the main
302 make process with -jX, where X is the number of CPUs (cores).
303 However, make sure you have enough RAM available for
304 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
306 If you are unsure, select N.
308 config PKG_BUILD_JOBS

319 prompt "Parallelize the default package build rule (May break build)"
320 depends on PKG_BUILD_PARALLEL
323 Always set the default package build rules to parallel build.
325 WARNING: This may break build or kill your cat, as it builds
326 packages with multiple jobs that are probably not tested in
327 a parallel build environment.
329 Only say Y, if you don't mind fixing broken packages.
330 Before reporting build bugs, set this to N and re-run the build.
332 config TOOLCHAIN_PARALLEL
334 prompt "Parallelize the toolchain build (May break build)"
335 depends on PKG_BUILD_PARALLEL
338 Build the toolchain with parallel make jobs.
339 This speeds up the toolchain build on SMP machines, but may
340 break the build for certain toolchain versions.
342 If you say Y, toolchain build might break.
343 Before reporting build bugs, set this to N and re-run the build.

384 config STRIP_KERNEL_EXPORTS
385 bool "Strip unnecessary exports from the kernel image"
387 Reduces kernel size by stripping unused kernel exports from the kernel image
388 Note that this might make the kernel incompatible with any kernel modules that
389 were not selected at the time the kernel image was created
392 bool "Strip unnecessary functions from libraries"
394 Reduces libraries to only those functions that are necessary for using all
395 selected packages (including those selected as <M>)
396 Note that this will make the system libraries incompatible with most of the packages
397 that are not selected during the build process

466 If enabled log files will be written to the ./log directory
468 config SRC_TREE_OVERRIDE
469 bool "Enable package source tree override" if DEVEL
471 If enabled, you can force a package to use a git tree as source
472 code instead of the normal tarball. Create a symlink 'git-src'
473 in the package directory, pointing to the .git tree that you want
474 to pull the source code from

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