22 help
23 When this option is disabled, software which provides patented functionality
24 will not be built. In case software provides optional support for patented
25 functionality, this optional support will get disabled for this package.

29 bool "Compile with full language support"
30 help
31 When this option is enabled, packages are built with the full versions of
32 iconv and GNU gettext instead of the default OpenWrt stubs. If uClibc is
33 used, it is also built with locale support.

37 bool "Attempt to link host utilities statically"

39 Linking host utilities like sed or firmware-utils statically increases the
40 portability of the generated ImageBuilder and SDK tarballs; however, it may
41 fail on some Linux distributions.

90 prompt "Compile certain packages parallelized"
91 default y
92 help
93 This adds a -jX option to certain packages that are known to behave well
94 for parallel build. By default, the package make processes use the main
95 jobserver, in which case this option only takes effect when you add -jX
96 to the make command.

105 Add -Wformat -Werror=format-security to the CFLAGS. You can disable
106 this per package by adding PKG_CHECK_FORMAT_SECURITY:=0 in the package
107 Makefile.

113 default y
114 help
115 This passes the main make process jobserver fds to package builds,
116 enabling full parallelization across different packages.
117
118 Note that disabling this may overcommit CPU resources depending on the
119 -j level of the main make process, the number of package submake jobs
120 selected below and the number of actual CPUs present.
121 Example: If the main make is passed a -j4 and the submake -j
122 is also set to 4, we may end up with 16 parallel make processes
123 in the worst case.

140 help
141 Always set the default package build rules to parallel build.
142
143 WARNING: This may break build or kill your cat, as it builds packages
144 with multiple jobs that are probably not tested in a parallel build
145 environment.
146
147 Only say Y if you don't mind fixing broken packages. Before reporting
148 build bugs, set this to N and re-run the build.

192 help
193 Reduces kernel size by stripping unused kernel exports from the kernel
194 image. Note that this might make the kernel incompatible with any kernel
195 modules that were not selected at the time the kernel image was created.

200 Reduces libraries to only those functions that are necessary for using all
201 selected packages (including those selected as <M>). Note that this will
202 make the system libraries incompatible with most of the packages that are
203 not selected during the build process.
