118 menu "Global build settings"
121 bool "Select all packages by default"
124 comment "General build options"
128 prompt "Disable ipkg/opkg installation on the target"
131 This removes all ipkg data from the target directory before building the root fs
135 prompt "Enable large file (files > 2 GB) support"
138 Enable large file (files > 2 GB) support.
140 config SHADOW_PASSWORDS
142 prompt "Enable shadow password support"
145 Enable shadow password support.
148 prompt "Binary stripping method"
149 default USE_STRIP if EXTERNAL_TOOLCHAIN
150 default USE_STRIP if USE_GLIBC || USE_EGLIBC
153 Select the binary stripping method you wish to use.
158 This will install unstripped binaries (useful for native compiling/debugging)
163 This will install binaries stripped using strip from binutils
172 This will install binaries stripped using sstrip
178 prompt "Strip arguments"
180 default "--strip-unneeded --remove-section=.comment --remove-section=.note" if DEBUG
181 default "--strip-all"
183 Specifies arguments passed to the strip command when stripping binaries
186 bool "Strip unnecessary functions from libraries"
188 Reduces libraries to only those functions that are necessary for using all
189 selected packages (including those selected as <M>)
190 Note that this will make the system libraries incompatible with most of the packages
191 that are not selected during the build process
193 config STRIP_KERNEL_EXPORTS
195 bool "Strip unnecessary exports from the kernel image"
197 Reduces kernel size by stripping unused kernel exports from the kernel image
198 Note that this might make the kernel incompatible with any kernel modules that
199 were not selected at the time the kernel image was created
201 comment "Package build options"
205 prompt "Compile packages with debugging info"
208 Adds -g3 to the CFLAGS
211 bool "Install debugging binaries into a staging directory"
214 This will install all compiled package binaries into build_dir/target-*/debug-*/,
215 useful for cross-debugging via gdb/gdbserver
219 prompt "Enable IPv6 support in packages"
222 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
224 comment "Kernel build options"
226 config KERNEL_KALLSYMS
227 bool "Compile the kernel with symbol table information"
230 This will give you more information in stack traces from kernel oopses
232 config KERNEL_PROFILING
233 bool "Compile the kernel with profiling enabled"
236 Enable the extended profiling support mechanisms used by profilers such
239 config KERNEL_DEBUG_FS
240 bool "Compile the kernel with Debug Filesystem enabled"
244 debugfs is a virtual file system that kernel developers use to put
245 debugging files into. Enable this option to be able to read and
246 write to these files.
251 bool "Advanced configuration options (for developers)"
256 prompt "Show broken platforms / packages" if DEVEL
259 config DOWNLOAD_FOLDER
261 prompt "Download folder" if DEVEL

270 prompt "Automatic rebuild of packages" if DEVEL
273 Automatically rebuild packages when their files change
277 prompt "Build suffix to append to the BUILD_DIR variable" if DEVEL
280 Build suffix to append to the BUILD_DIR variable, i.e: build_dir_suffix
282 config TARGET_ROOTFS_DIR
284 prompt "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
287 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with custom path.
288 Use this option to re-define the location of the target root file system directory.
292 prompt "Use ccache" if DEVEL
295 Compiler cache; see http://ccache.samba.org/
297 config EXTERNAL_KERNEL_TREE
299 prompt "Use external kernel tree" if DEVEL
302 config KERNEL_GIT_CLONE_URI
304 prompt "Enter git repository to clone" if DEVEL
307 Enter the full git repository path i.e.:
308 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
309 This will create a git clone of the kernel in your build
312 config KERNEL_GIT_LOCAL_REPOSITORY
314 prompt "Enter path to local reference repository" if DEVEL
317 Enter a full pathname to a local reference git repository.
318 In this instance, the --refererence option of git clone will
319 be used thus creating a quick local clone of your repo.
322 menuconfig TARGET_OPTIONS
323 bool "Target Options" if DEVEL
325 config TARGET_OPTIMIZATION
327 prompt "Target Optimizations" if TARGET_OPTIONS
328 default DEFAULT_TARGET_OPTIMIZATION
330 Optimizations to use when building for the target host.
334 prompt "Use software floating point by default" if TARGET_OPTIONS
336 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
338 If your target CPU does not have a Floating Point Unit (FPU) or a
339 kernel FPU emulator, but you still wish to support floating point
340 functions, then everything will need to be compiled with soft floating
341 point support (-msoft-float).
