# Builds linker config file, ld.config.txt, from the specified template

# under $(LOCAL_PATH)/etc/*.
|
#
|
# Inputs:
|
# (expected to follow an include of $(BUILD_SYSTEM)/base_rules.mk)
|
# ld_config_template: template linker config file to use,
|
# e.g. $(LOCAL_PATH)/etc/ld.config.txt
|
# vndk_version: version of the VNDK library lists used to update the
|
# template linker config file, e.g. 28
|
# lib_list_from_prebuilts: should be set to 'true' if the VNDK library
|
# lists should be read from /prebuilts/vndk/*
|
# libz_is_llndk: should be set to 'true' if libz must be included in
|
# llndk and not in vndk-sp
|
# Outputs:
|
# Builds and installs ld.config.$VER.txt or ld.config.vndk_lite.txt
