It will cache the result of previous builds to speed up future builds. By default, the cache is stored in $HOME/.buildroot-ccache. Note that Buildroot does not try to invalidate the cache contents when the compiler changes in an incompatible way. Therefore, if you make a change to the compiler version and/or configuration, you are responsible for purging the ccache cache by removing the $HOME/.buildroot-ccache directory. if BR2_CCACHE config BR2_CCACHE_DIR string "Compiler cache location" default "$(HOME)/.buildroot-ccache" help Where ccache should store cached files.

For example, if your project is known to require more space than the default max cache size, then you might want to increase the cache size to a suitable amount using the -M (--max-size) option. The string you specify here is passed verbatim to ccache. Refer to ccache documentation for more details. These initial settings are applied after ccache has been compiled. config BR2_CCACHE_USE_BASEDIR bool "Use relative paths" default y help Allow ccache to convert absolute paths within the output directory into relative paths. During the build, many -I include directives are given with an absolute path. These absolute paths end up in the hashes that are computed by ccache. Therefore, when you build from a different directory, the hash will be different and the cached object will not be used. To improve cache performance, set this option to y. This allows ccache to rewrite absolute paths within the output directory into relative paths. Note that only paths within the output directory will be rewritten; therefore, if you change BR2_HOST_DIR to point outside the output directory and subsequently move it to a different location, this will lead to cache misses. This option has as a result that the debug information in the object files also has only relative paths. Therefore, make sure you cd to the build directory before starting gdb. See the section "COMPILING IN DIFFERENT DIRECTORIES" in the ccache manual for more information. endif config BR2_ENABLE_DEBUG bool "build packages with debugging symbols" help Build packages with debugging symbols enabled.

Optimizing compilation takes somewhat more time, and a lot more memory for a large function. With -O, the compiler tries to reduce code size and execution time, without performing any optimizations that take a great deal of compilation time. -O turns on the following optimization flags: -fdefer-pop -fdelayed-branch -fguess-branch-probability -fcprop-registers -floop-optimize -fif-conversion -fif-conversion2 -ftree-ccp -ftree-dce -ftree-dominator-opts -ftree-dse -ftree-ter -ftree-lrs -ftree-sra -ftree-copyrename -ftree-fre -ftree-ch -funit-at-a-time -fmerge-constants. -O also turns on -fomit-frame-pointer on machines where doing so does not interfere with debugging. config BR2_OPTIMIZE_2 bool "optimization level 2" help Optimize even more. GCC performs nearly all supported optimizations that do not involve a space-speed tradeoff. The compiler does not perform loop unrolling or function inlining when you specify -O2. As compared to -O, this option increases both compilation time and the performance of the generated code. -O2 turns on all optimization flags specified by -O. It also turns on the following optimization flags: -fthread-jumps -fcrossjumping -foptimize-sibling-calls -fcse-follow-jumps -fcse-skip-blocks -fgcse -fgcse-lm -fexpensive-optimizations -fstrength-reduce -frerun-cse-after-loop -frerun-loop-opt -fcaller-saves -fpeephole2 -fschedule-insns -fschedule-insns2 -fsched-interblock -fsched-spec -fregmove -fstrict-aliasing -fdelete-null-pointer-checks -freorder-blocks -freorder-functions -falign-functions -falign-jumps -falign-loops -falign-labels -ftree-vrp -ftree-pre. Please note the warning under -fgcse about invoking -O2 on programs that use computed gotos. config BR2_OPTIMIZE_3 bool "optimization level 3" help Optimize yet more. -O3 turns on all optimizations specified by -O2 and also turns on the -finline-functions, -funswitch-loops and -fgcse-after-reload options. config BR2_OPTIMIZE_G bool "optimize for debugging" depends on BR2_TOOLCHAIN_GCC_AT_LEAST_4_8 help Optimize for debugging. This enables optimizations that do not interfere with debugging. It should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable level of optimization while maintaining fast compilation and a good debugging experience. config BR2_OPTIMIZE_S bool "optimize for size" help Optimize for size. -Os enables all -O2 optimizations that do not typically increase code size. It also performs further optimizations designed to reduce code size. -Os disables the following optimization flags: -falign-functions -falign-jumps -falign-loops -falign-labels -freorder-blocks -freorder-blocks-and-partition -fprefetch-loop-arrays -ftree-vect-loop-version This is the default. config BR2_OPTIMIZE_FAST bool "optimize for fast (may break packages!)" depends on BR2_TOOLCHAIN_GCC_AT_LEAST_4_6 help Optimize for fast. Disregard strict standards compliance. -Ofast enables all -O3 optimizations. It also enables optimizations that are not valid for all standard-compliant programs, so be careful, as it may break some packages.

No shared libraries will be installed on the target. This potentially increases your code size and should only be used if you know what you are doing. Note that some packages may not be available when this option is enabled, due to their need for dynamic library support. config BR2_SHARED_LIBS bool "shared only" depends on BR2_BINFMT_SUPPORTS_SHARED help Build and use only shared libraries.

See the Buildroot documentation for more details on this feature. config BR2_GLOBAL_PATCH_DIR string "global patch directories" help You may specify a space separated list of one or more directories containing global package patches. For a specific version of a specific package , patches are applied as follows: First, the default Buildroot patch set for the package is applied from the package's directory in Buildroot. Then for every directory - - that exists in BR2_GLOBAL_PATCH_DIR, if the directory /// exists, then all *.patch files in this directory will be applied. Otherwise, if the directory / exists, then all *.patch files in the directory will be applied. menu "Advanced" config BR2_COMPILER_PARANOID_UNSAFE_PATH bool "paranoid check of library/header paths" default y help By default, when this option is disabled, when the Buildroot cross-compiler will encounter an unsafe library or header path (such as /usr/include, or /usr/lib), the compiler will display a warning. By enabling this option, this warning is turned into an error, which will completely abort the build when such unsafe paths are encountered. Note that this mechanism is available for both the internal toolchain (through the toolchain wrapper and binutils patches) and external toolchain backends (through the toolchain wrapper). config BR2_FORCE_HOST_BUILD bool "Force the building of host dependencies" help Build all available host dependencies, even if they are already installed on the system. This option can be used to ensure that the download cache of source archives for packages remain consistent between different build hosts. This option will increase build time. config BR2_REPRODUCIBLE bool "Make the build reproducible (experimental)" # SOURCE_DATE_EPOCH support in toolchain-wrapper requires GCC 4.4 depends on BR2_TOOLCHAIN_GCC_AT_LEAST_4_4 help This option will remove all sources of non-reproducibility from the build process. For a given Buildroot configuration, this allows to generate exactly identical binaries from one build to the other, including on different machines. The current implementation is restricted to builds with the same output directory. Many (absolute) paths are recorded in intermediary files, and it is very likely that some of these paths leak into the target rootfs. If you build with the same O=... path, however, the result is identical. This is labeled as an experimental feature, as not all packages behave properly to ensure reproducibility. config BR2_PER_PACKAGE_DIRECTORIES bool "Use per-package directories (experimental)" help This option will change the build process of Buildroot package to use per-package target and host directories. This is useful for two related purposes: - Cleanly isolate the build of each package, so that a given package only "sees" the dependencies it has explicitly expressed, and not other packages that may have by chance been built before. - Enable top-level parallel build.
