221 comment "Package build options"
225 prompt "Compile packages with debugging info"
228 Adds -g3 to the CFLAGS
232 prompt "Enable IPv6 support in packages"
235 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
237 config PKG_BUILD_PARALLEL
239 prompt "Compile certain packages parallelized"
242 This adds a -jX option to certain packages that are known to
243 behave well for parallel build.
245 Note that this may overcommit CPU resources depending on the
246 -j level of the main make process, the number of package
247 submake jobs selected below and the number of actual CPUs present.
248 Example: If the main make is passed a -j4 and the submake -j
249 is also set to 4, we may end up with 16 parallel make processes
252 You get maximum build performance, if you set the package build
253 jobs to the number of CPUs (cores) available and also start the main
254 make process with -jX, where X is the number of CPUs (cores).
255 However, make sure you have enough RAM available for
256 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
258 If you are unsure, select N.
260 config PKG_BUILD_JOBS
262 prompt "Number of package submake jobs (2-512)"
265 depends on PKG_BUILD_PARALLEL
267 The number of jobs (-jX) to pass to packages submake.
269 config PKG_DEFAULT_PARALLEL
271 prompt "Parallelize the default package build rule (May break build)"
272 depends on PKG_BUILD_PARALLEL
275 Always set the default package build rules to parallel build.
277 WARNING: This may break build or kill your cat, as it builds
278 packages with multiple jobs that are probably not tested in
279 a parallel build environment.
281 Only say Y, if you don't mind fixing broken packages.
282 Before reporting build bugs, set this to N and re-run the build.
284 config TOOLCHAIN_PARALLEL
286 prompt "Parallelize the toolchain build (May break build)"
287 depends on PKG_BUILD_PARALLEL
290 Build the toolchain with parallel make jobs.
291 This speeds up the toolchain build on SMP machines, but may
292 break the build for certain toolchain versions.
294 If you say Y, toolchain build might break.
295 Before reporting build bugs, set this to N and re-run the build.

301 default USE_STRIP if EXTERNAL_TOOLCHAIN
302 default USE_STRIP if USE_GLIBC || USE_EGLIBC
305 Select the binary stripping method you wish to use.
310 This will install unstripped binaries (useful for native compiling/debugging)
315 This will install binaries stripped using strip from binutils
324 This will install binaries stripped using sstrip
329 prompt "Strip arguments"
331 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
332 default "--strip-all"
334 Specifies arguments passed to the strip command when stripping binaries
336 config STRIP_KERNEL_EXPORTS
338 bool "Strip unnecessary exports from the kernel image"
340 Reduces kernel size by stripping unused kernel exports from the kernel image
341 Note that this might make the kernel incompatible with any kernel modules that
342 were not selected at the time the kernel image was created
345 bool "Strip unnecessary functions from libraries"
347 Reduces libraries to only those functions that are necessary for using all
348 selected packages (including those selected as <M>)
349 Note that this will make the system libraries incompatible with most of the packages
350 that are not selected during the build process

405 This will create a git clone of the kernel in your build
408 config KERNEL_GIT_LOCAL_REPOSITORY
409 string "Enter path to local reference repository" if DEVEL
412 Enter a full pathname to a local reference git repository.
413 In this instance, the --refererence option of git clone will
414 be used thus creating a quick local clone of your repo.
416 menuconfig TARGET_OPTIONS

426 bool "Use software floating point by default" if TARGET_OPTIONS
428 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
430 If your target CPU does not have a Floating Point Unit (FPU) or a
431 kernel FPU emulator, but you still wish to support floating point
432 functions, then everything will need to be compiled with soft floating
433 point support (-msoft-float).
435 Most people will answer N.
