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.

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).
