# When building this project, we actually generate several components which
# are the following:
#
#  - the emulator-ui program (which is target-agnostic)
#  - the target-specific qemu-android-$ARCH programs (headless emulation engines)
#  - the "standalone" emulator programs (embed both UI and engine in a single
#    binary and process), i.e. "emulator" for ARM and "emulator-x86" for x86.
#
# This file defines static host libraries that will be used by at least two
# of these components.

###  gen-hw-config-defs: Generate hardware configuration definitions header
###
###  The 'gen-hw-config.py' script is used to generate the hw-config-defs.h
###  header from the an .ini file like android/avd/hardware-properties.ini
###
###  Due to the way the Android build system works, we need to regenerate
###  it for each module (the output will go into a module-specific directory).
###
###  This defines a function that can be used inside a module definition
###
###  $(call gen-hw-config-defs)
###

# First, define a rule to generate a dummy "emulator_hw_config_defs" module
# which purpose is simply to host the generated header in its output directory.
