23 When this option is disabled, software which provides patented functionality will not be built.
24 In case software provides optional support for patented functionality,
25 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 iconv and GNU gettext
32 instead of the default OpenWrt stubs. If uClibc is used, it is also built with locale support.

38 Linking host utilities like sed or firmware-utils statically increases the portability of the

88 help
89 This adds a -jX option to certain packages that are known to
90 behave well for parallel build. By default the package make processes
91 use the main jobserver, in which case this option only takes effect
92 when you add -jX to the make command.

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

138 Always set the default package build rules to parallel build.
139
140 WARNING: This may break build or kill your cat, as it builds
141 packages with multiple jobs that are probably not tested in
142 a parallel build environment.
143
144 Only say Y, if you don't mind fixing broken packages.
145 Before reporting build bugs, set this to N and re-run the build.
