This tristate choose allows to select to build only some applications with PIE enabled. On MIPS binaries are getting about 30% bigger when PIE is activated for the, which is a huge increase. Network exposed applications like dnsmasq should then be build with PIE enabled, but some applications which are normally not parsing data from the network do not have it activated. The regular option should give a good trade off between extra flash and RAM memory usage and security. This changes the default from building no applications with PIE to build some specifically marked applications with PIE enabled. This option is only activated for targets with bigger flash and RAM to not consume extra memory on the very small targets. On SDK builds the Regular option should always be selected, because some tiny targets share the applications with big targets and only the images for the tiny targets should contain the none PIE applications, but the images for the normal targets should use PIE. The shared packages should always use PIE when it should be normally activated. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: Petr Štetiar <ynezz@true.cz> |

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
