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"

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
177 bool "Strip unnecessary functions from libraries"
179 Reduces libraries to only those functions that are necessary for using all
180 selected packages (including those selected as <M>)
181 Note that this will make the system libraries incompatible with most of the packages
182 that are not selected during the build process
184 config STRIP_KERNEL_EXPORTS
186 bool "Strip unnecessary exports from the kernel image"
188 Reduces kernel size by stripping unused kernel exports from the kernel image
189 Note that this might make the kernel incompatible with any kernel modules that
190 were not selected at the time the kernel image was created
192 comment "Package build options"
196 prompt "Compile packages with debugging info"
199 Adds -g3 to the CFLAGS
202 bool "Install debugging binaries into a staging directory"
205 This will install all compiled package binaries into build_dir/target-*/debug-*/,
206 useful for cross-debugging via gdb/gdbserver
210 prompt "Enable IPv6 support in packages"
213 Enable IPV6 support in packages (passes --enable-ipv6 to configure scripts).
215 comment "Kernel build options"
217 config KERNEL_KALLSYMS
218 bool "Compile the kernel with symbol table information"
221 This will give you more information in stack traces from kernel oopses
223 config KERNEL_PROFILING
224 bool "Compile the kernel with profiling enabled"
227 Enable the extended profiling support mechanisms used by profilers such
230 config KERNEL_DEBUG_FS
231 bool "Compile the kernel with Debug Filesystem enabled"
235 debugfs is a virtual file system that kernel developers use to put
236 debugging files into. Enable this option to be able to read and
237 write to these files.

261 prompt "Automatic rebuild of packages" if DEVEL
264 Automatically rebuild packages when their files change
268 prompt "Build suffix to append to the BUILD_DIR variable" if DEVEL
271 Build suffix to append to the BUILD_DIR variable, i.e: build_dir_suffix
273 config TARGET_ROOTFS_DIR
275 prompt "Override the default TARGET_ROOTFS_DIR variable" if DEVEL
278 Override the default TARGET_ROOTFS_DIR variable content $(BUILD_DIR) with custom path.
279 Use this option to re-define the location of the target root file system directory.
283 prompt "Use ccache" if DEVEL
286 Compiler cache; see http://ccache.samba.org/
288 config EXTERNAL_KERNEL_TREE
290 prompt "Use external kernel tree" if DEVEL
293 config KERNEL_GIT_CLONE_URI
295 prompt "Enter git repository to clone" if DEVEL
298 Enter the full git repository path i.e.:
299 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
300 This will create a git clone of the kernel in your build
303 config KERNEL_GIT_LOCAL_REPOSITORY
305 prompt "Enter path to local reference repository" if DEVEL
308 Enter a full pathname to a local reference git repository.
309 In this instance, the --refererence option of git clone will
310 be used thus creating a quick local clone of your repo.
313 menuconfig TARGET_OPTIONS
314 bool "Target Options" if DEVEL
316 config TARGET_OPTIMIZATION
318 prompt "Target Optimizations" if TARGET_OPTIONS
319 default DEFAULT_TARGET_OPTIMIZATION
321 Optimizations to use when building for the target host.
325 prompt "Use software floating point by default" if TARGET_OPTIONS
327 depends on (arm || armeb || powerpc || mipsel || mips) && !HAS_FPU
329 If your target CPU does not have a Floating Point Unit (FPU) or a
330 kernel FPU emulator, but you still wish to support floating point
331 functions, then everything will need to be compiled with soft floating
332 point support (-msoft-float).
