Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.

android_build's Issues

How do you build this?

I followed the steps -
mkdir -p ~/arrow
cd arrow
repo init -u https://github.com/ArrowOS/android_manifest.git -b arrow-12.1
repo sync
wait 2.5 hours no errors as far as I can see

But the file I got in the end is empty ;p I didn't have to rename it even it came as arrow_device-codename.mk
( Although I didn't see it at first in the folder ... I pasted this in terminal : lineage_device-codename.mk -> arrow_device-codename.mk but it did nothing as far as I can tell? It complains about not knowing what that command is. But weirdly after that I finally saw the file arrow_device......mk)

Anyways file is empty and instructions are really not helpful so I have no idea what to do... I am stuck on this step:
Now inside arrow_device.mk
Change “lineage” to “arrow” & “common_full_phone.mk” to “common.mk”
For example:
$(call inherit-product, vendor/arrow/config/common.mk)
Change PRODUCT_NAME value “lineage_device-codename”
( “lineage_beryllium” ) to arrow_device-codename ( i.e, arrow_beryllium )

Everything is empty , so idk if it's telling me to paste this into the file? IF it is it's really confusing I have no idea what am I supposed to change? This ? $(call inherit-arrow_alioth, vendor/arrow/config/common.mk)

:P Looking at stuff after this in the guide it's even more confusing as idk where the device tree is located?
.. it's been a while since A11 release , maybe the steps are dif now?
