config BR2_ZCAT
string "zcat command"
default "gzip -d -c"
help
Command to be used to extract a gzip'ed file to stdout.
zcat is identical to gunzip -c except that the former may
not be available on your system.
Default is "gzip -d -c"
Other possible values include "gunzip -c" or "zcat".
config BR2_BZCAT
string "bzcat command"
default "bzcat"
help
Command to be used to extract a bzip2'ed file to stdout.
bzcat is identical to bunzip2 -c except that the former may
not be available on your system.
Default is "bzcat"
Other possible values include "bunzip2 -c" or "bzip2 -d -c".
config BR2_TAR_OPTIONS
string "Tar options"
default ""
help
Options to pass to tar when extracting the sources.
E.g. " -v --exclude='*.svn*'" to exclude all .svn internal files
and to be verbose.
config BR2_DL_DIR
string "Download dir"
default "$(BASE_DIR)/dl"
help
Directory to store all the source files that we need to fetch.
If the Linux shell environment has defined the BUILDROOT_DL_DIR
environment variable, then this overrides this configuration item.
The default is $(BASE_DIR)/dl
source "target/device/Config.in.mirrors"
config BR2_STAGING_DIR
string "Toolchain and header file location?"
default "$(BUILD_DIR)/staging_dir"
help
This is the location where the toolchain will be installed. The
toolchain will not work if it is moved from this location.
Therefore, if you wish to package up a uClibc toolchain, it is
important that is is set to the final location where the toolchain
will be used.
Most people will leave this set to the default value of
"$(BUILD_DIR)/staging_dir".
config BR2_FPU_SUFFIX
bool "Add '_nofpu' suffix for softfloat toolchains"
default n
help
If the toolchain is configured to use softfloat, then
the "_nofpu" suffix will be added to the toolchain build
directory name and to any rootfs image name
config BR2_TOPDIR_PREFIX
string "Custom build dir prefix"
default ""
help
Add a custom string to the beginning of the build directories.
build_ARCH -> [PREFIX]_build_ARCH
toolchain_build_ARCH -> [PREFIX]_toolchain_build_ARCH
config BR2_TOPDIR_SUFFIX
string "Custom build dir suffix"
default ""
help
Add a custom string to the end of the build directories.
build_ARCH -> build_ARCH_[SUFFIX]
toolchain_build_ARCH -> toolchain_build_ARCH_[SUFFIX]
config BR2_ROOTFS_PREFIX
string "Custom root fs prefix"
default "rootfs"
help
Add a custom string to the beginning of the root file system name.

default "" if !BR2_TARGET_ATMEL
help
Add a custom string to the end of the root file system name.
config BR2_GNU_BUILD_SUFFIX
string "GNU build hostname suffix"
default "pc-linux-gnu"
help
The string used to pass to configure scripts via the
--build= option. Just specify the suffix here, the leading
arch will be filled in automatically.
Here's some copy and paste build host options for you:
linux: pc-linux-gnu
cygwin: pc-cygwin
os x: apple-darwin7 / apple-darwin8
config BR2_GNU_TARGET_SUFFIX
string "GNU target suffix"
default "linux-uclibcgnueabi" if BR2_ARM_EABI
default "linux-uclibc"
help
The string used to pass to configure scripts via the
--target= option. Just specify the suffix here, the leading
arch will be filled in automatically.
Most users will want to stick with the default setting, though
other users (most notably ARM EABI) like to add on to this in
order to stay in line with gcc conventions.
Default options are:
linux-uclibcgnueabi for ARM EABI
linux-uclibc for the rest
gnuhurd-uclibc for the hurd
config BR2_JLEVEL
int "Number of jobs to run simultaneously"
default "1"
help
Number of jobs to run simultaneously
config BR2_PREFER_IMA
bool "prefer IMA compiles"
default n
help
Where possible, compile package with Inter Module Analysis.
This potentially uses alot of system resources on your compile
host with the benefit of creating smaller binaries for the target.
If unsure, say No.
WARNING: This is highly experimental at the moment.
config BR2_DEPRECATED
bool "Show packages that are deprecated or obsolete"
default n
help
This option hides outdated/obsolete versions of packages.
config BR2_RECENT
bool "Show packages that are of the latest major version"
default y
help
This option show recent versions of packages.
choice
prompt "strip"
default BR2_STRIP_strip
help
Select whether to strip binaries and libraries for the target
or not.
strip is the normal strip command
sstrip is a strip that discards more than the normal strip
none do not strip (only for debugging!)
config BR2_STRIP_strip
bool "strip"
help
strip is the normal strip command
config BR2_STRIP_sstrip
bool "sstrip"
select BR2_PACKAGE_SSTRIP_HOST

config BR2_STRIP_none
bool "none"
help
none do not strip (only for debugging!)
endchoice
config BR2_PREFER_STATIC_LIB
bool "prefer static libraries"
default n
help
Where possible, build and use static libraries for the target.
This potentially increases your code size and should only be
used if you know what you do.
The default is to build dynamic libraries and use those on
the target filesystem.
WARNING: This is highly experimental at the moment.
config BR2_HAVE_MANPAGES
bool "manpages on the target"
default n
help
Leave the manpages on the target.
If you say n here, your target will not contain any
manpage.
config BR2_HAVE_INFOPAGES
bool "infopages on the target"
default n
help
Leave the infopages on the target.
If you say n here, your target will not contain any
infopage.
