# add_circular(name ...)
|
|
#
|
|
# Creates a shared library with circular/mutual dependencies on other libraries.
|
|
#
|
|
# Typical use: circular dependencies between libs in /usr/lib/system
|
|
#
|
|
# Parameters:
|
|
# * SOURCES: Sources to build the library from. This function will internally create an object library for them.
|
|
# * OBJECTS: Object libraries to build the library from. (Because we cannot add object libraries into object libraries.)
|
|
# * SIBLINGS: Which "circular" libraries we should link against in the final pass.
|
|
# All specified libs must also be built with this function!
|
|
# * STRONG_SIBLINGS: Which "circular" libraries we should link against in the 1st pass.
|
|
# Only use for special cases, e.g. if this library reexports from this strong siblibg
|
|
# and another sibling depends on this reexport's existence.
|
|
# * DEPENDENCIES: Which standard libraries we should link against.
|
|
# * LINK_FLAGS: Extra linker flags, e.g. an alias list
|
|
# * UPWARD: Add an upward dependency. This affects initialization order. The specified dependency will only be
|
|
# loaded and initialized after the current library is fully loaded. This is needed to break
|
|
# certain dependency issues, esp. if a libSystem sublibrary depends on a library that depends on libSystem
|
|
# and has initializers. dyld bails out unless this dependency is upward.
|
|
# * STRONG_DEPENDENCIES: Which regular dependencies we should link against in the firstpass.
|
|
# Just like STRONG_SIBLINGS, this should only be used in special cases. The intended use case is when
|
|
# another sibling depends on symbols linked into this sibling from dependencies (usually static libraries).
|
|
# Current use case is for Security to link to its static libraries in the firstpass,
|
|
# because coretls_cfhelpers depends on them.
