Customizing CM7 build process

[Guest sm4tik]

Hi,

I've been looking for ways to customize the building process of CM7 for my own use. Just to be clear here, I have no intentions of forking a rom etc., I just like to customize stuff and learn as I go. The one thing I just discovered was vendor/cyanogen/products/cyanogen_blade.mk and all the other inherited makefiles. It makes sense that these files are scattered around, but to make things clear for myself, rather than editing each of these I was wondering if there is a way to override the set things with an extra "custom.mk" file which would be read last.

So basically I have 2 questions for now:

1) How do I inherit or include my own makefile so it gets read last, ie. overrides/adds/removes whatever I want it to?

2) Can I exclude for instance built apps with something like PRODUCT_PACKAGES -= AppNotNeeded App2NotNeeded, or any other way?

Thanks in advance

Uhh.. I've tried to make sense of the makefiles and it's quite a jungle, but since there is no such thing as ./configure --without-live-wallpapers, I'm still hunting ;) I've tried to read some tutorials and alike, but none are answering my questions. Could someone atleast give me a hint about the hierarchy of the makefiles so I know which ones have more weight. I'll give an example.

I'd like to compile with a custom set of locales/languages. There are these lines in device/zte/blade/device_blade.mk

# Inherit from those products. Most specific first.

$(call inherit-product, $(SRC_TARGET_DIR)/product/languages_full.mk)

$(call inherit-product, $(SRC_TARGET_DIR)/product/full_base.mk)

Now in build/target/product/full_base.mk, which was inherited in device/zte/blade/device_blade.mk there's also the line

$(call inherit-product, $(SRC_TARGET_DIR)/product/languages_full.mk)

Can I just change the line in device/zte/blade/device_blade.mk to point to something like $(SRC_TARGET_DIR)/product/languages_custom.mk (which I will create) and this will be the only change I need to make, or do I have to edit both makefiles accordingly.

Yes, I know I could just comment out the unwanted languages in languages_full.mk, but I'd consider that a workaround, not a solution :)
