If this option is enabled, downloads will only be attempted
from the primary download site. Other locations, like the
package's official download location or the backup download
site, will not be considered. Therefore, if the package is
not present on the primary site, the download fails.

that the project can be built even if the upstream tarball
locations disappear.

config BR2_CCACHE
bool "Enable compiler cache"
help
This option will enable the use of ccache, a compiler
cache. 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.
config BR2_CCACHE_INITIAL_SETUP
string "Compiler cache initial setup"
help
Initial ccache settings to apply, such as --max-files or --max-size.
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.

save space, mainly by removing debugging symbols. Debugging
symbols on the target are needed for native debugging, but
not when remote debugging is used.

help
Set the optimization level for gcc
config BR2_OPTIMIZE_0
bool "optimization level 0"
help
Do not optimize. This is the default.
config BR2_OPTIMIZE_1
bool "optimization level 1"
help
Optimize. 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

-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_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 option will enable the use of google breakpad, a
library and tool suite that allows you to distribute an
application to users with compiler-provided debugging
information removed, record crashes in compact "minidump"

stack traces from these minidumps. Breakpad can also write
minidumps on request for programs that have not crashed.

help
Enable stack smashing protection support using GCC's
-fstack-protector option family.
See http://www.linuxfromscratch.org/hints/downloads/files/ssp.txt
for details.
Note that this requires the toolchain to have SSP
support. This is always the case for glibc and eglibc
toolchain, but is optional in uClibc toolchains.

bool "None"
help
Disable stack-smashing protection.
config BR2_SSP_REGULAR
bool "-fstack-protector"
help
Emit extra code to check for buffer overflows, such as stack
smashing attacks. This is done by adding a guard variable to
functions with vulnerable objects. This includes functions
that call alloca, and functions with buffers larger than 8
bytes. The guards are initialized when a function is entered
and then checked when the function exits. If a guard check
fails, an error message is printed and the program exits.
config BR2_SSP_STRONG

The default is to build dynamic libraries and use those on
the target filesystem, except when the architecture and/or
the selected binary format does not support shared
libraries.
config BR2_STATIC_LIBS
bool "static only"
help
Build and use only static libraries. No shared libraries
will be instaled on the target. This potentially increases
your code size and should only be used if you know what you

this option is enabled, due to their need for dynamic
library support.
config BR2_SHARED_LIBS

help
Build and use only shared libraries. This is the recommended
solution as it saves space and build time.
config BR2_SHARED_STATIC_LIBS
bool "both static and shared"
depends on BR2_BINFMT_SUPPORTS_SHARED

Build both shared and static libraries, but link executables

may be useful to link some of the applications statically.

help
A package override file is a short makefile that contains
variable definitions of the form <pkg>_OVERRIDE_SRCDIR,
which allows to tell Buildroot to use an existing directory
as the source directory for a particular package. See the
Buildroot documentation for more details on this feature.
config BR2_GLOBAL_PATCH_DIR

help
You may specify a space separated list of one or more directories
containing global package patches. For a specific version
<packageversion> of a specific package <packagename>, 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 - <global-patch-dir> - that exists in
BR2_GLOBAL_PATCH_DIR, if the directory
<global-patch-dir>/<packagename>/<packageversion>/ exists, then all
*.patch files in this directory will be applied.
Otherwise, if the directory <global-patch-dir>/<packagename> exists,
then all *.patch files in the directory will be applied.

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 gcc and binutils patches) and external
toolchain backends (through the external toolchain wrapper).
