A cxx_universal_executable()
rule takes a target via its binary
attribute, builds it for multiple architectures and combines the result into a single binary using lipo
.
Parameters
-
name
: name of the target -
default_target_platform
: specifies the default target platform, used when no platforms are specified on the command line -
target_compatible_with
: a list of constraints that are required to be satisfied for this target to be compatible with a configuration -
compatible_with
: a list of constraints that are required to be satisfied for this target to be compatible with a configuration -
exec_compatible_with
: a list of constraints that are required to be satisfied for this target to be compatible with an execution platform -
visibility
: a list of visibility patterns restricting what targets can depend on this one -
within_view
: a list of visibility patterns restricting what this target can depend on -
metadata
: a key-value map of metadata associated with this target -
tests
: a list of targets that provide tests for this one -
modifiers
: an array of modifiers associated with this target -
executable
: A build target identifying the binary which will be built for multiple architectures. The target will be transitioned into different configurations, with distinct architectures.The target can be one of:
cxx_binary()
[shared]
subtargetcxx_library()
cxx_library()
which havepreferred_linkage = shared
attribute
-
executable_name
: By default, the name of the universal executable is same as the name of the binary from thebinary
target attribute. Setexecutable_name
to override the default. -
universal
: Controls whether the output is universal binary. Any value overrides the presence of theconfig//cpu/constraints:universal-enabled
constraint. Read the rule docs for more information on resolution.
Details
The output of the rule is a universal binary:
- If
config//cpu/constraints:universal-enabled
is present in the target platform. - If the
universal
attribute is set toTrue
.
If none of the conditions are met, then the rule acts as a nop alias()
.
The universal
attribute, if present, takes precedence over constraint.
For example, if universal = False
, then the presence of the constraint
would not affect the output.
