Things to verify

Move into ~/aex_rom/device/motorola/osprey using cd

  1. Open aosp_osprey.mk or lineage_osprey.mk or anything similar named file (<rom_name>_osprey.mk) using nano.
  • Check if the path in the line $(call inherit-product, vendor/aosp/common.mk) exists. If not, modify as required.
  1. Open aosp.dependencies or lineage.dependencies or anything similar named file (<rom_name>.dependencies) using nano.
  • Check if the dependencies without remote tag has been cloned.
  1. Check if AndroidProducts.mk file points to a valid make file.

Move into ~/aex_rom/device/motorola/msm8916-common using cd. If there is any .dependencies file (not present in this case), make sure to clone the dependencies in the file.

Further modifications

  1. AEX currently doesn't officially support pie for osprey. So by following the trails of vendor/aosp/vendorsetup.sh, the following file vendor/aosp/tools/get_official_devices.py had to be edited to allow Oreo devices to be shown on Pie list as well.
  2. To avoid error: error: vendor/motorola/msm8916-common: MODULE.TARGET.SHARED_LIBRARIES.libril already defined by hardware/ril/libril. the Android.mk file under hardware/ril/libril was renamed to Android.mk.bak
  3. Toolchain is required (arm-eabi-7.3.1 as of now). Use the following command:
git clone https://github.com/Subinsmani/prebuilts_gcc_linux-x86_arm_arm-eabi-7.2 -b master prebuilts/gcc/linux-x86/arm/arm-eabi-7.3.1

Build the ROM

cd ~/aex_rom  
. build/envsetup.sh  
lunch

Select device number from list.

make aex -j10
