# UnoApiHeadersTarget

# defined by platform
#  gb_UnoApiHeadersTarget_select_variant

# Allow to redefine header variant.
#
# On iOS we use static linking because dynamic loading of own code
# isn't allowed by the iOS App Store rules, and we want our code to be
# eventually distributable there as part of apps.
#
# To avoid problems that this causes together with the lovely
# intentional breaking of the One Definition Rule, for iOS we always
# generate comprehensive headers for certain type RDBS. (The ODR
# breakage doesn't harm, by accident or careful design, on platforms
# where shared libraries are used.) To avoid generating the same headers
# more than once, we are silently "redirecting" the target to point to
# comprehensive headers instead.
#
# Example:
# If gb_UnoApiHeadersTarget_select_variant is defined as
#
# ifeq ($(DISABLE_DYNLOADING),TRUE)
# gb_UnoApiHeadersTarget_select_variant = $(if $(filter udkapi,$(1)),comprehensive,$(2))
# else
# gb_UnoApiHeadersTarget_select_variant = $(2)
# endif
#
# then, for the DISABLE_DYNLOADING case, whenever a makefile uses
# $(call gb_UnoApiHeadersTarget_get_target,udkapi) or $(call
# gb_UnoApiHeadersTarget_get_dir,udkapi), it will get target or dir for
# comprehensive headers instead.
#
# We are experimenting with static linking on Android, too. There for
# technical reasons to get around silly limitations in the OS, sigh.
#
# gb_UnoApiHeadersTarget_select_variant api default-variant
