Oh I should probably add in a few older findings here too

soong json generation has improved a lot since pie. There are now saner functions to handle this. For reference, see this.
So, now our custom map's config.mk would looks something like this:
https://github.com/PotatoProject-next/vendor_potato/commit/6ca5af3c9647898ea60feab9c8711fa64333aa06

Oh also, if you come across a build error on libselinux, this should fix it:
https://github.com/PotatoProject-next/external_selinux/commit/b4177583030e8e6a16f8976c570562d319ce5a1b
Not sure if this is the right thing to do, but it at least gets things going.

Most are probably aware, but yeah. Might as well add it here.
add_lunch_combo is deprecated and lunch relies on a build var:
Set COMMON_LUNCH_CHOICES in your AndroidProducts.mk, instead.

Also, AOSP now has fuchsia targets 😆

Thank you Google, very cool.

Checking the PATH variable from make, there seems to be only
/home/agentfabulous/q-preview/prebuilts/build-tools/path/linux-x86:/home/agentfabulous/q-preview/out/.path by default.
/home/agentfabulous/q-preview/out/.path has symlinks to ../.path_interposer

I don't know what I was expecting, but yes the only differnce now is that the system PATH variable is no more considered at all. We need to add paths to prebuilt binaries in our kernel.mk or we can look into path_interposer's inclusions.

So, path_interposer will back up the current PATH data to a file in outdir. This is restored when soong is exiting. If you manage to kill soong during the build (or even hit Ctrl+c a bunch of times when it starts exiting from the initial interrupt), you'll be left with the PATH set for the build.

inline kernel compilation now works :)

Though I guess we could do something nicer, this should do the job for now.

You may also be wondering as to why I'm using the prebuilt make while I'm running instructions against the original path. This is because path.go will throw an error if I try to build specifying any path tools such as make.

Oh also, I should mention, the soong kernel header generator also calls make. Fixed it up now, just need to clean-up and add my path override.

HAHAYES

that's enough for today oof

hell ye boii

TARGET_OUT_INTERMEDIATE_LIBRARIES has now been removed.
We are expected to use per-module intermediate dirs instead.

Oh well.

yeeet; PRODUCT_SOONG_NAMESPACES pickup (sort of) works now :D

We'd need to move quite a few things from BoardConfig to product config makefiles
