# This script creates a tarball that contains toolchains for android P.
# Before running it, please modify the following 4 variables
# - ANDROID_TREE
# - ARTIFACTS_DIR_ARM64
# - ARTIFACTS_DIR_X86_64
# - TO_DIR_BASE
# Then just run it from anywhere with no arguments.
# The constructed tarball will contain the sysroots under amd64 and arm.
#
# *** PREREQUISITES ***
# Before running the script, follow these steps:
#
# 1. Download prebuilts for ARM64 and x86_64
#
# Go to go/ab, select branch git_pi-arc-dev. Pick a -userdebug build for all
# architectures, then download cheets_${arch}-target_files-${build_id}.zip.
# Extract those files and point ARTIFACTS_DIR_${ARCH} to the respective
# directories.
# The prebuilts will provide most of the binaries.
#
# 2. Make sure you have the right version of the prebuilts
#
# $ grep "ro.build.version.release" ${ARTIFACTS_DIR_${ARCH}}/SYSTEM/build.prop
#
# The build artifacts will be created in subdirectories of out/ where the script
# will find them. Do not delete out/ or rebuild before running the script!
#
# 4. Run the script!
#
# $ ./gather.sh
