- config BUILD_PATENTED

- bool "Compile with support for patented functionality"
- help
- When this option is disabled, software which provides patented functionality
- will not be built. In case software provides optional support for patented
- functionality, this optional support will get disabled for this package.
- config BUILD_NLS
- default n
- bool "Compile with full language support"
- help
- When this option is enabled, packages are built with the full versions of
- iconv and GNU gettext instead of the default libreCMC stubs. If uClibc is
- used, it is also built with locale support.
- config BUILD_STATIC_TOOLS
- default n
- bool "Attempt to link host utilities statically"
- help
- Linking host utilities like sed or firmware-utils statically increases the
- portability of the generated ImageBuilder and SDK tarballs; however, it may
- fail on some Linux distributions.

- Enable shadow password support.

- This removes all ipkg/opkg status data files from the target directory
- before building the root filesystem.
- config COLLECT_KERNEL_DEBUG

- This collects debugging symbols from the kernel and all compiled modules.

- later.

- help
- Enable IPv6 support in packages (passes --enable-ipv6 to configure scripts).
- config PKG_BUILD_PARALLEL
- bool
- prompt "Compile certain packages parallelized"
- default y
- help
- This adds a -jX option to certain packages that are known to behave well
- for parallel build. By default, the package make processes use the main
- jobserver, in which case this option only takes effect when you add -jX
- to the make command.
- If you are unsure, select N.
- config PKG_CHECK_FORMAT_SECURITY
- bool
- prompt "Enable gcc format-security"
- default n
- help
- Add -Wformat -Werror=format-security to the CFLAGS. You can disable
- this per package by adding PKG_CHECK_FORMAT_SECURITY:=0 in the package
- Makefile.
- config PKG_BUILD_USE_JOBSERVER
- bool
- prompt "Use top-level make jobserver for packages"
- depends on PKG_BUILD_PARALLEL
- default y
- help
- This passes the main make process jobserver fds to package builds,
- enabling full parallelization across different packages.
- Note that disabling this may overcommit CPU resources depending on the
- -j level of the main make process, the number of package submake jobs
- selected below and the number of actual CPUs present.
- Example: If the main make is passed a -j4 and the submake -j
- is also set to 4, we may end up with 16 parallel make processes
- in the worst case.

- depends on PKG_BUILD_PARALLEL
- depends on BROKEN
- default n
- help
- Always set the default package build rules to parallel build.
- WARNING: This may break build or kill your cat, as it builds packages
- with multiple jobs that are probably not tested in a parallel build
- environment.
- Only say Y if you don't mind fixing broken packages. Before reporting
- build bugs, set this to N and re-run the build.

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